git clone https://github.com/photon-hq/notebooklm-kit.git && cd notebooklm-kit && npm run setup
```
**Requirements:** Node.js >=18.0.0
## Version
Current version: **2.1.1**
## Available Scripts
When working with the repository, you can use the following npm scripts:
| Script | Description |
|--------|-------------|
| `npm install` | Install dependencies and automatically build (runs postinstall) |
| `npm run setup` | Full setup: install dependencies, Playwright, and build |
| `npm run build` | Compile TypeScript to JavaScript |
| `npm run build:dev` | Build only (no reinstall) |
| `npm run dev` | Watch mode (auto-rebuild on file changes) |
| `npm run clean` | Remove compiled dist/ directory |
Development
**First-time setup:**
```bash
npm run setup
```
**Build only (no reinstall):**
```bash
npm run build:dev
```
**Watch mode (auto-rebuild):**
```bash
npm run dev
```
**Clean build:**
```bash
npm run clean && npm run build
```
## Quick Start
### 1. Install the package
```bash
npm install notebooklm-kit
```
### 2. Set up authentication
**Auto (browser):** Create `.env` with `GOOGLE_EMAIL` and `GOOGLE_PASSWORD` (no 2FA required)
**Manual:** Create `.env` with `NOTEBOOKLM_AUTH_TOKEN` and `NOTEBOOKLM_COOKIES` from browser DevTools (Network → Cookie header, Console → `window.WIZ_global_data.SNlM0e`)
### 3. Use the SDK
```typescript
import { NotebookLMClient } from 'notebooklm-kit';
import dotenv from 'dotenv';
// Load .env file from project root (automatically detected)
dotenv.config();
async function main() {
const sdk = new NotebookLMClient({
// Credentials are automatically loaded from .env file
// Priority: NOTEBOOKLM_AUTH_TOKEN/NOTEBOOKLM_COOKIES > GOOGLE_EMAIL/GOOGLE_PASSWORD
});
try {
await sdk.connect();
// List notebooks
const notebooks = await sdk.notebooks.list();
console.log(`Found ${notebooks.length} notebooks`);
// Create a notebook
const notebook = await sdk.notebooks.create({
title: 'My Research',
emoji: '📚',
});
console.log(`Created: ${notebook.title}`);
} catch (error) {
console.error('Error:', error);
} finally {
sdk.dispose();
}
}
main();
```
**Note:** The SDK automatically loads credentials from environment variables. See [SDK Initialization](#sdk-initialization) for all configuration options.
### Running Examples
The repository includes working examples in the [`examples/`](examples/) directory. To run them:
1. **Set up your `.env` file** in the project root (see [Authentication](#2-set-up-authentication) above)
2. **Run any example** using `tsx`:
```bash
npx tsx examples/notebook-list.ts
npx tsx examples/chat-basic.ts
```
**Chat Example Usage:**
```bash
# Interactive mode (prompts for notebook and message)
npx tsx examples/chat-basic.ts
# With notebook ID and message (streaming mode - default)
npx tsx examples/chat-basic.ts "What are the key findings?"
# Non-streaming mode (get complete response at once)
npx tsx examples/chat-basic.ts "What are the key findings?" --no-stream
```
**Note:** The examples automatically detect and load the `.env` file from the project root, regardless of where you run them from.

## Core Concepts
### SDK Initialization
**Methods:** `sdk.connect()` | `sdk.dispose()`
**Basic Usage:**
```typescript
import { NotebookLMClient } from 'notebooklm-kit';
import dotenv from 'dotenv';
dotenv.config(); // Load .env from project root
const sdk = new NotebookLMClient({
// Credentials loaded automatically from environment variables:
// NOTEBOOKLM_AUTH_TOKEN, NOTEBOOKLM_COOKIES
// or GOOGLE_EMAIL, GOOGLE_PASSWORD
});
try {
await sdk.connect(); // Initialize SDK, authenticate, start auto-refresh
// Now you can use sdk.notebooks, sdk.sources, etc.
const notebooks = await sdk.notebooks.list();
} finally {
sdk.dispose(); // Always cleanup
}
```
**Explicit Credentials:**
```typescript
const sdk = new NotebookLMClient({
authToken: process.env.NOTEBOOKLM_AUTH_TOKEN!,
cookies: process.env.NOTEBOOKLM_COOKIES!,
// or
auth: {
email: process.env.GOOGLE_EMAIL!,
password: process.env.GOOGLE_PASSWORD!,
},
});
await sdk.connect();
```
**Enable Debug Mode:**
Debug mode provides detailed logging for troubleshooting, API calls, authentication, and internal operations.
**Option 1: Environment Variable (Recommended)**
```bash
# In your .env file
NOTEBOOKLM_DEBUG=true
```
**Option 2: Config Option**
```typescript
const sdk = new NotebookLMClient({
debug: true, // Enable debug logging
// ... other config
});
await sdk.connect();
```
**Option 3: Development Mode**
```bash
# Automatically enables debug in development
NODE_ENV=development
```
**What Debug Mode Logs:**
- ✅ RPC call details (method names, arguments, responses)
- ✅ Authentication flow (login steps, credential extraction)
- ✅ Auto-refresh operations (token refresh attempts, timing)
- ✅ Streaming responses (chunk processing, parsing)
- ✅ Error details (full stack traces, API responses)
- ✅ Response parsing (chunked data processing, validation)
**Example Debug Output:**
```
[DEBUG] RPC Call: wXbhsf with args: [null, 1, null, [2]]
[DEBUG] Response received: 200 OK
[DEBUG] Parsing chunked response: 3 chunks found
[DEBUG] Auto-refresh: Token expires in 5 minutes, refreshing now...
[DEBUG] Authentication: Extracting credentials from browser...
```
**Disable Debug:**
```typescript
// Explicitly disable (overrides environment variable)
const sdk = new NotebookLMClient({
debug: false,
});
```
```bash
# Or in .env
NOTEBOOKLM_DEBUG=false
```
Connection Flow
1. **Credentials Resolution** (in priority order):
- Provided in config (`authToken`/`cookies`)
- Environment variables (`NOTEBOOKLM_AUTH_TOKEN`/`NOTEBOOKLM_COOKIES`)
- Saved credentials (`credentials.json` in project root) - **reused automatically**
- Auto-login (if `auth.email`/`auth.password` provided) - **only if no saved credentials**
**Note:** Set `FORCE_REAUTH=true` in `.env` to force re-authentication and ignore saved credentials
2. **Initialization:**
- Creates RPC client with credentials
- Initializes all services (`notebooks`, `sources`, `artifacts`, etc.)
- Starts auto-refresh manager (if enabled)
3. **Auto-Refresh:**
- Begins automatically after `connect()`
- Runs in background, doesn't block operations
- Updates credentials and cookies automatically
Cleanup
**Always call `dispose()` when done:**
- Stops auto-refresh background timers
- Prevents memory leaks
- Resets client state
- Required for graceful shutdown
```typescript
try {
await sdk.connect();
// ... use SDK ...
} finally {
await sdk.dispose(); // Always cleanup
}
```
### Authentication Overview
Authentication is handled automatically when you call `sdk.connect()`. Credentials are resolved in this priority order:
1. Provided in config (`authToken`/`cookies`)
2. Environment variables (`NOTEBOOKLM_AUTH_TOKEN`/`NOTEBOOKLM_COOKIES`)
3. Saved credentials (`credentials.json` in project root)
4. Auto-login (if `auth.email`/`auth.password` provided)
See the [Authentication](#authentication) section for detailed setup instructions and all configuration options.
### Quota Limits
Reference: [Official Documentation](https://support.google.com/notebooklm/answer/16213268)
**Plan Types:** `standard` (default) | `plus` | `pro` | `ultra`
| Limit | Standard | Plus | Pro | Ultra |
|-------|----------|------|-----|-------|
| **Notebooks** | 100/user | 200/user | 500/user | 500/user |
| **Sources/Notebook** | 50 | 100 | 300 | 600 |
| **Words/Source** | 500,000 | 500,000 | 500,000 | 500,000 |
| **File Size** | 200MB | 200MB | 200MB | 200MB |
| **Chats/Day** | 50 | 200 | 500 | 5,000 |
| **Audio/Video/Day** | 3 | 6 | 20 | 200 |
| **Reports/Day** | 10 | 20 | 100 | 1,000 |
| **Deep Research/Month** | 10 | 90 | 600 | 6,000 |
| **Mind Maps** | Unlimited | Unlimited | Unlimited | Unlimited |
Important Notes
- **Daily quotas** reset after 24 hours
- **Monthly quotas** reset after 30 days
- **Word/File Limits:** NotebookLM rejects sources >500k words or >200MB. Copy-protected PDFs cannot be imported.
- **Server-Side Enforcement:** Data Tables, Infographics, Slides (limits vary)
- **Client-Side Validation:** Optional (`enforceQuotas: true`), disabled by default
- **Plan Selection:** Set during SDK initialization: `plan: 'pro'`
## Authentication
### Auto-Login (Recommended)
**Method:** Use `auth` config with email/password
```typescript
const sdk = new NotebookLMClient({
auth: {
email: process.env.GOOGLE_EMAIL,
password: process.env.GOOGLE_PASSWORD,
headless: true, // default: true
},
});
await sdk.connect(); // Logs in, extracts auth token, prompts for cookies, saves to credentials.json
```
Environment Variables (.env file)
**File Location:** Create `.env` in your **project root** directory (same directory as `package.json`).
```bash
# .env file location: /path/to/your-project/.env
# Option 1: Auto-login with email/password (recommended - requires no 2FA)
GOOGLE_EMAIL="your-email@gmail.com"
GOOGLE_PASSWORD="your-password"
# Option 2: Manual credentials (for production or when auto-login isn't available)
NOTEBOOKLM_AUTH_TOKEN="ACi2F2NZSD7yrNvFMrCkP3vZJY1R:1766720233448"
NOTEBOOKLM_COOKIES="_ga=GA1.1.1949425436.1764104083; SID=g.a0005AiwX...; ..."
# Optional: Retry configuration
NOTEBOOKLM_MAX_RETRIES=1 # Default: 1
NOTEBOOKLM_RETRY_DELAY=1000 # Default: 1000ms
NOTEBOOKLM_RETRY_MAX_DELAY=5000 # Default: 5000ms
# Optional: Debug mode (enables detailed logging)
NOTEBOOKLM_DEBUG=true # Enable debug logging for troubleshooting
# Optional: Force re-authentication (ignore saved credentials)
FORCE_REAUTH=true
```
**Important:**
- `.env` file must be in the **project root** (not in subdirectories)
- Account must NOT have 2FA enabled (or use app-specific passwords)
- The `.env` file is automatically ignored by git (see `.gitignore`)
### Manual Credentials
**Method:** Provide `authToken` and `cookies` directly
```typescript
const sdk = new NotebookLMClient({
authToken: process.env.NOTEBOOKLM_AUTH_TOKEN!,
cookies: process.env.NOTEBOOKLM_COOKIES!,
enforceQuotas: true, // optional
plan: 'standard', // optional: 'standard' | 'plus' | 'pro' | 'ultra'
});
await sdk.connect();
```
Getting Credentials
1. **Auth Token**: Open https://notebooklm.google.com → DevTools (F12) → Console → Run: `window.WIZ_global_data.SNlM0e`
2. **Cookies**: DevTools → Network tab → Any request → Headers → Copy Cookie value
### Saved Credentials
**Location:** `credentials.json` in project root (e.g., `notebooklm-kit/credentials.json`)
When using auto-login with email/password:
1. Browser opens and authenticates
2. Auth token is extracted automatically
3. You're prompted to manually paste cookies
4. Credentials are saved to `credentials.json` for future use
**Subsequent runs:**
- Saved credentials are automatically reused (no browser prompt)
- Faster startup - no need to re-enter cookies
- Credentials file is in project root for easy viewing/editing
**To force re-authentication:**
- Set `FORCE_REAUTH=true` in `.env`, or
- Delete `credentials.json` file
**Security Note:** `credentials.json` contains sensitive authentication data. It's automatically added to `.gitignore` to prevent accidental commits.
### Auto-Refresh Configuration
**Default:** Enabled with `'auto'` strategy (recommended)
```typescriptimproved
// Default: auto strategy (expiration-based + time-based fallback)
const sdk = new NotebookLMClient({
auth: { email: '...', password: '...' },
// autoRefresh: true (default)
});
// Time-based (simple, predictable)
autoRefresh: { strategy: 'time', interval: 10 * 60 * 1000 }
// Expiration-based (maximum efficiency)
autoRefresh: { strategy: 'expiration', refreshAhead: 5 * 60 * 1000 }
// Disable
autoRefresh: false
// Manual refresh
await sdk.refreshCredentials();
```
Auto-Refresh Details
- Credentials updated automatically after refresh
- Cookies kept in sync
- Runs in background, doesn't block operations
- See [Auto-Refresh Strategies](#auto-refresh-strategies) in Core Concepts
### Quota Management
**Method:** `sdk.getUsage()` | `sdk.getRemaining()` | `sdk.getQuotaManager()`
```typescript
const sdk = new NotebookLMClient({
auth: { email: '...', password: '...' },
enforceQuotas: true, // Enable client-side validation (disabled by default)
plan: 'pro', // Set plan for accurate limits
});
await sdk.connect();
// Check usage
const usage = sdk.getUsage();
const remaining = sdk.getRemaining('chats');
const limits = sdk.getQuotaManager().getLimits();
```
Quota Notes
- **Disabled by default** - enable with `enforceQuotas: true`
- Throws `RateLimitError` if limit exceeded (when enabled)
- Server-side enforcement always active (even if client-side disabled)
- See [Quota Limits](#quota-limits) table in Core Concepts
## Notebooks
Examples: [notebook-list.ts](examples/notebook-list.ts) | [notebook-get.ts](examples/notebook-get.ts) | [notebook-create.ts](examples/notebook-create.ts) | [notebook-update.ts](examples/notebook-update.ts) | [notebook-delete.ts](examples/notebook-delete.ts) | [notebook-share.ts](examples/notebook-share.ts)
### List Notebooks
**Method:** `sdk.notebooks.list()`
**Example:** [notebook-list.ts](examples/notebook-list.ts)
**Returns:** `Promise`
**Description:**
Lists all your notebooks (recently viewed). Returns a lightweight array of notebooks with essential information for display/selection.
**Return Fields:**
- `projectId: string` - Unique notebook ID (required for other operations)
- `title: string` - Notebook title
- `emoji: string` - Visual identifier
- `sourceCount: number` - Number of sources in the notebook
Notes
- Automatically filters out system notebooks (e.g., "OpenStax's Biology")
- Returns only notebooks you've recently viewed
- Does not include full notebook details (use `get()` for that)
- Does not include sources array (use `sources` service for source operations)
- Does not include sharing info (use `get()` for sharing details)
**Usage:**
```typescript
const notebooks = await sdk.notebooks.list()
console.log(`Found ${notebooks.length} notebooks`)
notebooks.forEach(nb => {
console.log(`${nb.emoji} ${nb.title} (${nb.sourceCount} sources)`)
})
```
---
### Get Notebook
**Method:** `sdk.notebooks.get(notebookId)`
**Example:** [notebook-get.ts](examples/notebook-get.ts)
**Parameters:**
- `notebookId: string` - The notebook ID (required)
**Returns:** `Promise`
**Description:**
Retrieves full details of a specific notebook, including analytics and sharing information. Makes parallel RPC calls to get complete notebook data.
**Return Fields:**
- `projectId: string` - Unique notebook ID
- `title: string` - Notebook title
- `emoji: string` - Visual identifier
- `sourceCount?: number` - Number of sources (analytics)
- `lastAccessed?: string` - Last accessed timestamp (ISO format, analytics)
- `sharing?: SharingSettings` - Sharing configuration:
- `isShared: boolean` - Whether notebook is shared
- `shareUrl?: string` - Share URL if shared
- `shareId?: string` - Share ID
- `publicAccess?: boolean` - Whether public access is enabled
- `allowedUsers?: string[]` - Array of user emails with access
Notes
- Validates notebook ID format before making RPC calls
- Calls both `RPC_GET_PROJECT` and `RPC_GET_SHARING_DETAILS` in parallel for efficiency
- Sharing data is optional - won't fail if unavailable
- Does not include sources array (use `sources` service for source operations)
- `lastAccessed` is extracted from notebook metadata if available
**Usage:**
```typescript
const notebook = await sdk.notebooks.get('notebook-id')
console.log(`Title: ${notebook.title}`)
console.log(`Sources: ${notebook.sourceCount || 0}`)
console.log(`Last accessed: ${notebook.lastAccessed || 'Never'}`)
if (notebook.sharing?.isShared) {
console.log(`Share URL: ${notebook.sharing.shareUrl}`)
}
```

Validation
- At least one field (`title` or `emoji`) must be provided
- Title maximum length: 100 characters
- Notebook ID is automatically trimmed (removes trailing spaces)
- Returns error if notebook doesn't exist
**Return Fields:**
Same as `get()` - includes `projectId`, `title`, `emoji`, `sourceCount`, `lastAccessed`, `sharing`
Notes
- Notebook ID is trimmed automatically to prevent issues with trailing spaces
- Only provided fields are updated (partial updates supported)
- Returns full notebook object after update (not just updated fields)

### Delete Notebook
**Method:** `sdk.notebooks.delete(notebookIds, options?)`
**Example:** [notebook-delete.ts](examples/notebook-delete.ts)
**Parameters:**
- `notebookIds: string | string[]` - Single notebook ID or array of IDs (required)
- `options?: DeleteNotebookOptions` - Optional deletion options:
- `mode?: 'parallel' | 'sequential'` - Execution mode (default: 'parallel')
**Returns:** `Promise`
**Description:**
Deletes one or more notebooks. For multiple notebooks, deletions are performed individually (either in parallel or sequentially) since Google's API does not support true batch deletion. Returns confirmation with deleted IDs and count.
**Return Fields:**
- `deleted: string[]` - Array of successfully deleted notebook IDs
- `count: number` - Number of notebooks successfully deleted
- `failed?: string[]` - Array of notebook IDs that failed to delete (only present if some failed)
- `failedCount?: number` - Number of notebooks that failed to delete
Validation
- All provided IDs are validated before deletion
- Throws `APIError` if any ID is invalid
- Supports both single ID and array of IDs
Deletion Modes
- **Parallel (default):** All notebooks are deleted simultaneously using `Promise.all()`. Faster but may hit rate limits.
- **Sequential:** Notebooks are deleted one at a time. Slower but more reliable and avoids rate limit issues.
Notes
- No confirmation required - deletion is immediate
- Google's API does not support batch deletion in a single call
- Multiple notebooks are deleted individually, one per API call
- Parallel mode is default but sequential mode is recommended for large batches to avoid rate limits
- Failed deletions are tracked separately - if some succeed and some fail, you'll get both `deleted` and `failed` arrays
- Throws error only if ALL deletions fail (partial failures return result with `failed` array)
**Usage:**
```typescript
// Delete single notebook
const result = await sdk.notebooks.delete('notebook-id')
console.log(`Deleted ${result.count} notebook: ${result.deleted[0]}`)
// Delete multiple notebooks (parallel - default)
const result = await sdk.notebooks.delete(['id-1', 'id-2', 'id-3'])
console.log(`Deleted ${result.count} notebooks: ${result.deleted.join(', ')}`)
// Delete multiple notebooks (sequential - recommended for large batches)
const result = await sdk.notebooks.delete(['id-1', 'id-2', 'id-3'], { mode: 'sequential' })
console.log(`Deleted ${result.count} notebooks: ${result.deleted.join(', ')}`)
if (result.failed && result.failed.length > 0) {
console.log(`Failed to delete: ${result.failed.join(', ')}`)
}
```

Validation
- Email addresses are validated using regex before sharing
- Throws `APIError` if any email is invalid
- Supports multiple users in a single call
Notes
- Notebook ID is automatically trimmed
- Makes prerequisite `JFMDGd` call before sharing (to initialize sharing state)

- `shareUrl` is always returned (constructed from notebook ID if not explicitly shared)
- Supports sharing with multiple users in a single operation
- Can combine user sharing with link access in one call
**Usage:**
```typescript
// Share with users (restricted access, notify enabled by default)
const result = await sdk.notebooks.share('notebook-id', {

})
// Share with users (silent, no notification)
const result = await sdk.notebooks.share('notebook-id', {
users: [
{ email: 'user@example.com', role: 2 },
],
notify: false,
accessType: 2,
})
// Enable link sharing (anyone with link)
const result = await sdk.notebooks.share('notebook-id', {
accessType: 1, // 1=anyone with link, 2=restricted
})

**Important Notes:**
- **Use `get()` to get video URL**: `get()` returns the video URL in `videoData` field, not a downloaded file
- **Use `download()` to download**: `download()` method downloads the video file to disk
- Video must be in `READY` state before downloading (check with `get()` first)
- Requires `GOOGLE_EMAIL` and `GOOGLE_PASSWORD` environment variables for authentication
- Uses Playwright for authentication and Node's http/https for reliable streaming download
- Shows real-time download progress (percentage and progress bar)
- Video is saved as `.mp4` in the specified output directory
**Usage:**
```typescript
// Get video URL (get() returns URL only)
const video = await sdk.artifacts.get('video-id', 'notebook-id')
console.log(`Video URL: ${video.videoData}`)
// Download video (download() saves file to disk)
const result = await sdk.artifacts.download('video-id', './downloads', 'notebook-id')
console.log(`Video saved to: ${result.filePath}`)
```
**Example Workflow:**
```typescript
// 1. Check video status and get URL
const video = await sdk.artifacts.get('video-id', 'notebook-id')
console.log(`Video URL: ${video.videoData}`)
if (video.state === ArtifactState.READY) {
// 2. Download video
const downloaded = await sdk.artifacts.download('video-id', './downloads', 'notebook-id')
console.log(`Downloaded: ${downloaded.filePath}`)
}
```

### Download Slides
**Method:** `sdk.artifacts.download(slideId, outputPath, notebookId, { downloadAs })`
**Example:** [slide-download-test.ts](examples/slide-download-test.ts)
**Interactive Example (`slide-download-test.ts`):**
The `slide-download-test.ts` example provides an interactive script for downloading slide decks:
1. **Lists and selects notebooks** - Shows all available notebooks and prompts for selection
2. **Lists and selects slide artifacts** - Displays all ready slide deck artifacts for the selected notebook
3. **Extracts slide image URLs** - Recursively searches artifact data structure to find slide image URLs
4. **Authenticates with Google** - Uses Playwright to authenticate with Google (handles 2FA)
5. **Downloads images** - Downloads each slide image using authenticated browser session
6. **Saves in requested format** - Saves as PNG (individual files) or PDF (single file)
**Environment Variables for `slide-download-test.ts`:**
- `NOTEBOOK_ID` - Optional: Pre-select a notebook ID (skips notebook selection)
- `GOOGLE_EMAIL` - Required: Google account email for authentication
- `GOOGLE_PASSWORD` - Required: Google account password for authentication
- `DOWNLOAD_AS` - Optional: `'pdf'` or `'png'` (defaults to interactive prompt)
- `OUTPUT_DIR` - Optional: Output directory path (defaults to `./downloads`)
**Usage:**
```bash
# Using tsx (recommended)
NOTEBOOK_ID=your-notebook-id GOOGLE_EMAIL=your@email.com GOOGLE_PASSWORD=yourpassword DOWNLOAD_AS=pdf npx tsx examples/slide-download-test.ts
# Or set environment variables separately
export GOOGLE_EMAIL=your@email.com
export GOOGLE_PASSWORD=yourpassword
export DOWNLOAD_AS=pdf
npx tsx examples/slide-download-test.ts
```
**SDK Method Parameters:**
- `slideId` (string, required): The slide artifact ID
- `outputPath` (string, required): Directory path to save the downloaded slides
- `notebookId` (string, required): The notebook ID containing the slides
- `downloadAs` (string, optional): Download format - `'pdf'` (default) or `'png'`
**Returns:** `{ filePath: string, data: Artifact }` - File path and artifact data
**Description:**
Downloads a slide deck artifact as PDF (default) or PNG files. Uses Playwright for authentication and handles the download automatically. PDF format saves all slides in a single file, while PNG format saves each slide as a separate image file.
**Format Options:**
**PDF (default):**
- Single PDF file containing all slides
- Filename: `.pdf`
- Saved directly in the output directory
**PNG:**
- Individual PNG files for each slide
- Saved in a subfolder named after the artifact: `/`
- Filenames: `slide_1.png`, `slide_2.png`, etc.
**Important Notes:**
- **Use `get()` to get slide URLs**: `get()` returns slide image URLs in `slideUrls` array, not downloaded files
- **Use `download()` to download**: `download()` method downloads the slides to disk
- Slides must be in `READY` state before downloading (check with `get()` first)
- Requires cookies to be configured in the RPC client
- Uses Playwright headless browser for authenticated download
- PDF generation uses `pdf-lib` if available, falls back to PNG if not installed
- PNG files are always saved individually in a subfolder
**Usage:**
```typescript
// Get slide URLs (get() returns URLs only)
const slides = await sdk.artifacts.get('slide-id', 'notebook-id')
console.log(`Slide URLs: ${slides.slideUrls?.length || 0} slides`)
slides.slideUrls?.forEach((url, i) => {
console.log(`Slide ${i + 1}: ${url}`)
})
// Download as PDF (default) - use download() method
const result = await sdk.artifacts.download('slide-id', './downloads', 'notebook-id')
console.log(`PDF saved to: ${result.filePath}`)
// Download as PNG files - use download() method
const resultPng = await sdk.artifacts.download('slide-id', './downloads', 'notebook-id', {
downloadAs: 'png'
})
console.log(`PNG files saved to: ${resultPng.filePath}`)
```
**Example Workflow:**
```typescript
// 1. Check slide status and get URLs
const slides = await sdk.artifacts.get('slide-id', 'notebook-id')
console.log(`Slide URLs: ${slides.slideUrls?.length || 0} slides`)
if (slides.state === ArtifactState.READY) {
// 2. Download as PDF (default)
const downloaded = await sdk.artifacts.download('slide-id', './downloads', 'notebook-id')
console.log(`Downloaded PDF: ${downloaded.filePath}`)
// Or download as PNG files
const pngSlides = await sdk.artifacts.download('slide-id', './downloads', 'notebook-id', {
downloadAs: 'png'
})
console.log(`Downloaded PNGs: ${pngSlides.filePath}`)
}
```

### Rename Artifact
**Method:** `sdk.artifacts.rename(artifactId, newTitle)`
**Example:** [artifact-rename.ts](examples/artifact-rename.ts)
**Parameters:**
- `artifactId: string` - The artifact ID (required)
- `newTitle: string` - New title (required)
**Returns:** `Promise`
**Description:**
Renames an artifact. Updates only the title field. Works for all artifact types.
**Return Fields:**
Same as `get()` - returns updated artifact with new title
Notes
- Only updates the title - other fields remain unchanged
- Works for all artifact types (quiz, flashcards, report, mind map, infographic, slide deck, audio, video)
- Returns full artifact object after update
**Usage:**
```typescript
// Rename any artifact
const updated = await sdk.artifacts.rename('artifact-id', 'My Updated Quiz')
console.log(`New title: ${updated.title}`)
// Rename audio artifact (use audioId from create() or list())
const audio = await sdk.artifacts.audio.create('notebook-id')
const renamed = await sdk.artifacts.rename(audio.audioId, 'My Audio Overview')
```
---
### Delete Artifact
**Method:** `sdk.artifacts.delete(artifactId, notebookId?)`
**Example:** [artifact-delete.ts](examples/artifact-delete.ts)
**Parameters:**
- `artifactId: string` - The artifact ID from `create()` or `list()` (required)
- `notebookId?: string` - Optional notebook ID (helpful if `get()` fails for audio/video)
**Returns:** `Promise`
**Description:**
Permanently deletes an artifact. Works for all artifact types. This action cannot be undone. Automatically detects artifact type and uses the correct RPC method.
Notes
- Deletion is permanent and cannot be undone
- Works for all artifact types (quiz, flashcards, report, mind map, infographic, slide deck, audio, video)
- Automatically detects artifact type by calling `get()` first
- Audio and video artifacts use V5N4be RPC with `[[2], artifactId]` structure
- Other artifacts use WxBZtb RPC with `[artifactId]` structure
- If `get()` fails, tries both methods (V5N4be first, then standard delete)
- Audio and video artifacts have their own artifactId (not the notebook ID)
**Usage:**
```typescript
// Delete any artifact (recommended - automatically detects type)
await sdk.artifacts.delete('artifact-id')
// Delete with notebook ID (helpful if get() fails)
await sdk.artifacts.delete('artifact-id', 'notebook-id')
// Note: Audio and video artifacts have their own artifactId from create() or list()
const audio = await sdk.artifacts.audio.create('notebook-id')
await sdk.artifacts.delete(audio.audioId) // Use audioId, not notebookId
```
---
### Share Artifact
**Method:** `sdk.artifacts.share(notebookId, options)`

**Returns:** `Promise`
**Description:**
Shares an artifact (or the notebook containing the artifact) with specific users or makes it publicly accessible via a shareable link. Artifacts are shared at the notebook level, so sharing an artifact shares the entire notebook.
**User Roles:**
| Role | Value | Description |
|------|-------|-------------|
| Editor | `2` | Can edit notebook content |
| Viewer | `3` | Can view notebook only |
| Remove | `4` | Remove user from shared list |
**Access Types:**

**Return Fields:**
- `shareUrl: string` - Share URL (always present)
- `success: boolean` - Whether the share operation succeeded
- `notebookId: string` - The notebook ID that was shared
- `accessType: 1|2` - Access type
- `isShared: boolean` - Whether the notebook is shared
- `users?: Array<{email: string, role: 2|3}>` - Users with access (if users were shared)
Validation
- Email addresses are validated using regex before sharing
- Throws `APIError` if any email is invalid
- Must provide either `users` array or `accessType=1` (anyone with link)
- Supports multiple users in a single call
Notes
- Artifacts are shared at the notebook level - sharing an artifact shares the entire notebook
- `notify` is only used when `users` are provided
- Default: `true` (users are notified when permissions change)
- Set to `false` to share silently
- `shareUrl` is always returned (constructed from notebook ID if not explicitly shared)
**Usage:**
```typescript
// Share with users (restricted access, notify enabled by default)
const result = await sdk.artifacts.share('notebook-id', {
users: [
{ email: 'user1@example.com', role: 2 }, // editor
{ email: 'user2@example.com', role: 3 }, // viewer
],
notify: true,
accessType: 2, // restricted
})
// Share with users (silent, no notification)
const result = await sdk.artifacts.share('notebook-id', {
users: [
{ email: 'user@example.com', role: 2 },
],
notify: false,
accessType: 2,
})
// Enable link sharing (anyone with link)
const result = await sdk.artifacts.share('notebook-id', {
accessType: 1, // anyone with link
})
console.log(`Share URL: ${result.shareUrl}`)
// Remove user (role: 4)
const result = await sdk.artifacts.share('notebook-id', {
users: [
{ email: 'user@example.com', role: 4 }, // remove
],
accessType: 2,
})
```
## Generation & Chat
Examples: [chat-basic.ts](examples/chat-basic.ts) | [chat-conversation.ts](examples/chat-conversation.ts) | [generation-set-chat-config.ts](examples/generation-set-chat-config.ts)
**Key Features:**
- ✅ **Streaming & Non-streaming modes** - Choose real-time streaming (`chatStream()`) or complete responses (`chat()`)
- ✅ **Source selection** - Chat with all sources or specific ones (interactive or programmatic)
- ✅ **Citation extraction** - Automatic citation tracking from responses
- ✅ **Conversation management** - Track conversations with IDs and history
- ✅ **Type-safe configuration** - Full TypeScript support with `ChatConfig` interface
- ✅ **Improved parser** - Based on Python SDK implementation for better reliability
**Choosing Between `chat()` and `chatStream()`:**
- **Use `chat()`** when you want the complete response at once (simpler, blocking)
- Returns complete response text after all chunks are received
- Best for scripts, automation, or when you need the full response before processing
- Use the `--no-stream` flag in the example script
- **Use `chatStream()`** when you want real-time updates (better UX, progressive display)
- Yields chunks as they arrive for real-time display
- Automatically handles thinking content buffering and revision detection
- Only displays the final response (no thinking steps or revision markers)
- Best for interactive applications or when you want immediate feedback
- Both methods support the same options (source selection, conversation history, etc.)
- Both methods extract citations and track conversation metadata
---
### Chat (Non-Streaming)
**Method:** `sdk.generation.chat(notebookId, prompt, options?)`
**Examples:**
- [chat-basic.ts](examples/chat-basic.ts) - Basic chat with all sources
- [chat-conversation.ts](examples/chat-conversation.ts) - Chat with conversation history
**Note:** The SDK now uses an improved parser based on the Python SDK implementation, providing better error handling, citation extraction, and streaming support. The chat request format has been restructured to match the official API format for better compatibility.
**Parameters:**
- `notebookId: string` - The notebook ID (required)
- `prompt: string` - Chat message/prompt (required)
- `options?: object` - Optional chat options:
- `sourceIds?: string[]` - Specific source IDs to query (uses all sources if omitted)
- `conversationHistory?: Array<{ message: string; role: 'user' | 'assistant' }>` - Conversation history for follow-up messages
- `conversationId?: string` - Conversation ID for continuing a conversation (auto-generated if not provided)
**Returns:** `Promise` - Complete AI response with metadata
**Type Import:**
```typescript
import type { ChatResponseData } from 'notebooklm-kit';
```
**ChatResponseData Interface:**
```typescript
interface ChatResponseData {
text: string; // Complete response text (thinking headers removed)
rawData?: any; // Raw response data from API
chunks?: StreamChunk[]; // All chunks received during streaming
conversationId?: string; // Conversation ID for continuing the conversation
citations: number[]; // Citation numbers extracted from response
}
```
**Description:**
Chat with your notebook content using AI. Returns the complete response after all chunks are received. This is the non-streaming mode - use `chatStream()` for real-time streaming responses.
**Response Format:**
- `text`: The complete response text with thinking headers automatically removed
- `rawData`: Raw response structure from the API (for advanced use cases)
- `chunks`: Array of all stream chunks received (if you need to inspect individual chunks)
- `conversationId`: ID for continuing the conversation
- `citations`: Array of citation numbers found in the response (e.g., `[1, 2, 3]`)
**Features:**
- ✅ Automatic source detection (uses all sources if none specified)
- ✅ Source selection support (filter to specific sources)
- ✅ Conversation history tracking
- ✅ Citation extraction
- ✅ Conversation ID management
- ✅ Type-safe options
Notes
- **Response format**: Returns `ChatResponseData` object with `text`, `citations`, `conversationId`, etc.
- **Text extraction**: The `text` field contains the complete response with thinking headers automatically removed
- **Citation extraction**: Citations are automatically extracted and available in the `citations` array
- **Conversation tracking**: Conversation ID is auto-generated if not provided and returned in response
- **Source selection**: If `sourceIds` is provided, only those sources are used for context
- **Auto source detection**: If `sourceIds` is omitted, all sources in the notebook are automatically fetched and used
- **Conversation history**: Use `conversationHistory` for follow-up messages to maintain context
- **Quota management**: Quota is checked before chat (if quota manager is enabled)
- **Usage tracking**: Usage is recorded after successful chat
- **Response aggregation**: Response is aggregated from all streaming chunks and returned as complete text
- **For streaming**: Use `chatStream()` for real-time streaming responses
**Usage:**
```typescript
// Chat with all sources (non-streaming)
const response = await sdk.generation.chat(
'notebook-id',
'What are the main findings from the research?'
)
console.log(response.text) // Complete response text
console.log(`Citations: [${response.citations.join(', ')}]`)
console.log(`Conversation ID: ${response.conversationId}`)
// Chat with specific sources
const response = await sdk.generation.chat(
'notebook-id',
'Summarize the methodology section',
{ sourceIds: ['source-id-1', 'source-id-2'] }
)
console.log(response.text)
// Follow-up message with conversation history
const response1 = await sdk.generation.chat('notebook-id', 'What is machine learning?')
const response2 = await sdk.generation.chat('notebook-id', 'Tell me more', {
conversationId: response1.conversationId,
conversationHistory: [
{ message: 'What is machine learning?', role: 'user' },
{ message: response1.text, role: 'assistant' }
]
})
console.log(response2.text)
```
---
### Chat Stream (Streaming)
**Method:** `sdk.generation.chatStream(notebookId, prompt, options?)`
**Examples:**
- [chat-basic.ts](examples/chat-basic.ts) - Streaming chat with all sources
- [chat-conversation.ts](examples/chat-conversation.ts) - Streaming multi-turn conversations
**Parameters:**
- `notebookId: string` - The notebook ID (required)
- `prompt: string` - Chat message/prompt (required)
- `options?: object` - Optional chat options:
- `sourceIds?: string[]` - Specific source IDs to query (uses all sources if omitted)
- `conversationHistory?: Array<{ message: string; role: 'user' | 'assistant' }>` - Conversation history for follow-up messages
- `conversationId?: string` - Conversation ID for continuing a conversation (auto-generated if not provided)
- `onChunk?: (chunk: StreamChunk) => void` - Callback function called for each chunk
- `showThinking?: boolean` - Whether to include thinking process in output (default: false)
**Returns:** `AsyncGenerator` - Async generator yielding stream chunks
**Type Import:**
```typescript
import type { StreamChunk } from 'notebooklm-kit';
```
**Description:**
Stream chat responses in real-time. Returns an async generator that yields chunks as they arrive from the API. Each chunk contains the **full accumulated text** up to that point (snapshot-based, not delta-based), allowing you to display responses as they're generated.
**Key Behaviors:**
- **Snapshot-based streaming**: Each `chunk.text` contains the complete response accumulated so far, not just the new portion
- **Thinking content buffering**: Thinking content (marked with `**Header**`) is automatically buffered and only the final response is displayed
- **Revision detection**: If the AI revises its response mid-stream, the revision is automatically handled and only the final version is shown
- **No revision markers**: The streaming client automatically filters out thinking steps and revision markers for a clean output
**StreamChunk Interface:**
```typescript
interface StreamChunk {
chunkNumber: number; // Chunk number (1-based, increments with each chunk)
byteCount: number; // Byte count for this chunk
text: string; // FULL accumulated text from start to this point (snapshot-based)
thinking: string[]; // Thinking headers extracted from text (e.g., ["Analyzing sources", "Formulating response"])
response: string; // Response text with thinking headers removed
metadata?: [string, string, number]; // [conversationId, messageId, timestamp]
messageIds?: [string, string]; // Message IDs: [conversationId, messageId]
timestamp?: number; // Timestamp from metadata
citations?: number[]; // Citation numbers extracted from text (e.g., [1, 2, 3])
rawData?: any; // Raw parsed data from API
isError?: boolean; // Is this an error chunk?
errorCode?: number; // Error code if isError is true
isThinking?: boolean; // Does this chunk contain thinking content?
isResponse?: boolean; // Does this chunk contain response content?
formatting?: any; // Formatting information
}
```
**Important Notes:**
- `chunk.text` contains the **complete accumulated response** (not incremental)
- To display incrementally, compare `chunk.text.length` with previous chunk length
- Thinking content is automatically filtered - you'll only see the final response
- Citations are extracted from the text using pattern matching `[1]`, `[2]`, etc.
- Conversation ID is available in `chunk.metadata[0]` or `chunk.messageIds[0]`
**Features:**
- ✅ Real-time streaming responses
- ✅ Citation extraction from each chunk
- ✅ Conversation metadata tracking
- ✅ Thinking/response separation
- ✅ Error detection and handling
- ✅ Progress callbacks via `onChunk`
Notes
- **Snapshot-based streaming**: Each `chunk.text` contains the complete accumulated response from the start, not just the new portion
- **Incremental display**: To display incrementally, compare `chunk.text.length` with previous chunk length and extract the new portion
- **Thinking content handling**: Thinking content (marked with `**Header**`) is automatically buffered and filtered - only the final response is displayed
- **Revision detection**: If the AI revises its response mid-stream, the revision is automatically detected and only the final version is shown
- **No revision markers**: The client automatically handles revisions without showing "Response revised by AI" markers
- **Citation extraction**: Citations are automatically extracted from text using pattern matching `[1]`, `[2]`, etc.
- **Conversation tracking**: Conversation ID and message IDs are available in `chunk.metadata` or `chunk.messageIds`
- **Quota management**: Quota is checked before streaming starts (if quota manager is enabled)
- **Usage tracking**: Usage is recorded after streaming completes
- **Callback support**: Use `onChunk` callback for real-time processing of each chunk
- **Error handling**: Error chunks are detected via `chunk.isError` and `chunk.errorCode`
**Usage:**
**Basic Streaming (Snapshot-based):**
```typescript
// Since chunk.text contains the FULL accumulated response, display incrementally
let lastDisplayedLength = 0;
for await (const chunk of sdk.generation.chatStream('notebook-id', 'What is this about?')) {
// chunk.text contains complete response so far - extract only new portion
if (chunk.text.length > lastDisplayedLength) {
const newText = chunk.text.substring(lastDisplayedLength);
process.stdout.write(newText);
lastDisplayedLength = chunk.text.length;
}
}
```
**Simple Streaming (Using response field):**
```typescript
// Use chunk.response which has thinking headers already removed
let lastResponseLength = 0;
for await (const chunk of sdk.generation.chatStream('notebook-id', 'Explain this')) {
if (chunk.response && chunk.response.length > lastResponseLength) {
const newText = chunk.response.substring(lastResponseLength);
process.stdout.write(newText);
lastResponseLength = chunk.response.length;
}
}
```
**Streaming with Callback:**
```typescript
for await (const chunk of sdk.generation.chatStream('notebook-id', 'Explain this', {
onChunk: (chunk) => {
console.log(`Chunk ${chunk.chunkNumber}: ${chunk.byteCount} bytes`);
if (chunk.citations && chunk.citations.length > 0) {
console.log(`Citations: ${chunk.citations.join(', ')}`);
}
}
})) {
// Display incrementally
if (chunk.text.length > lastDisplayedLength) {
const newText = chunk.text.substring(lastDisplayedLength);
process.stdout.write(newText);
lastDisplayedLength = chunk.text.length;
}
}
```
**Streaming with Specific Sources:**
```typescript
let lastDisplayedLength = 0;
for await (const chunk of sdk.generation.chatStream(
'notebook-id',
'Compare these sources',
{ sourceIds: ['source-id-1', 'source-id-2'] }
)) {
if (chunk.text.length > lastDisplayedLength) {
const newText = chunk.text.substring(lastDisplayedLength);
process.stdout.write(newText);
lastDisplayedLength = chunk.text.length;
}
}
```
**Collect Citations and Metadata:**
```typescript
const citations = new Set();
let conversationId: string | undefined;
let messageIds: [string, string] | undefined;
let lastDisplayedLength = 0;
for await (const chunk of sdk.generation.chatStream('notebook-id', 'What are the key findings?')) {
// Track conversation ID and message IDs
if (chunk.metadata) {
conversationId = chunk.metadata[0];
messageIds = chunk.metadata.slice(0, 2) as [string, string];
}
// Collect citations
if (chunk.citations) {
chunk.citations.forEach(citation => citations.add(citation));
}
// Display response incrementally
if (chunk.text.length > lastDisplayedLength) {
const newText = chunk.text.substring(lastDisplayedLength);
process.stdout.write(newText);
lastDisplayedLength = chunk.text.length;
}
}
console.log(`\nConversation ID: ${conversationId}`);
console.log(`Message IDs: ${messageIds?.join(', ')}`);
console.log(`Citations: [${Array.from(citations).sort((a, b) => a - b).join(', ')}]`);
```
**Example Output Format:**
```
The provided sources primarily discuss the field of Artificial Intelligence (AI)
and the transformative research paper "Attention Is All You Need" [1, 2].
The transformer architecture introduced in 2017 revolutionized AI by enabling
parallel processing and becoming the foundation for modern large language models [3, 4].
```
**Note:** The streaming client automatically:
- Buffers thinking content (won't display it)
- Detects and handles revisions (only shows final response)
- Removes thinking headers from output
- Extracts citations from text
- Tracks conversation metadata
---
### Set Chat Configuration
**Method:** `sdk.generation.setChatConfig(notebookId, config)`
**Example:** [generation-set-chat-config.ts](examples/generation-set-chat-config.ts)
**Parameters:**
- `notebookId: string` - The notebook ID (required)

- `customText?: string` - Custom prompt text (required if type is 'custom')
- `responseLength: 'default' | 'shorter' | 'longer'` - Response length (required)
**Returns:** `Promise` - Configuration result
**Type Import:**
```typescript
import type { ChatConfig } from 'notebooklm-kit';
```
**Description:**
Configure chat behavior before sending messages. Set the chat mode (default, custom prompt, or learning guide) and response length. This configuration affects all subsequent chat messages until changed. This is optional - you can use chat without setting configuration.
**Configuration Types:**
- **`default`**: Standard conversational responses - balanced and informative
- **`custom`**: Responses following a custom instruction/persona (requires `customText`)
- **`learning-guide`**: Educational responses optimized for learning and understanding
**Response Lengths:**
- **`default`**: Standard length responses - balanced detail
- **`shorter`**: Concise, brief responses - quick summaries
- **`longer`**: Detailed, comprehensive responses - in-depth explanations
**Usage:**
```typescript
// Set default configuration
await sdk.generation.setChatConfig('notebook-id', {
type: 'default',
responseLength: 'default'
})
// Set custom configuration with custom prompt
await sdk.generation.setChatConfig('notebook-id', {
type: 'custom',
customText: 'respond as a PhD student explaining complex concepts simply',
responseLength: 'longer'
})
// Set learning guide configuration
await sdk.generation.setChatConfig('notebook-id', {
type: 'learning-guide',
responseLength: 'shorter'
})
// Example: Configure for academic writing style
await sdk.generation.setChatConfig('notebook-id', {
type: 'custom',
customText: 'respond in an academic writing style with citations',
responseLength: 'longer'
})
```
**Note:** Configuration persists for the notebook until changed. You can update it anytime by calling `setChatConfig()` again with new values.
---
---
- ⚠️ This action is permanent and cannot be undone
- Each conversation has a unique ID that persists across sessions
- Use conversation IDs to manage multiple parallel conversations
- Deleting a conversation removes all message history for that conversation

- Tags are optional and can be added during creation or later
- Note type defaults to `REGULAR` (1) - use `GENERATED` (2) for AI-generated notes
- Returns immediately with note ID - no waiting required
**Usage:**
```typescript
// Create a simple note
const note = await sdk.notes.create('notebook-id', {
title: 'Meeting Notes',
content: 'Key points from today\'s meeting...',
})
console.log(`Created note: ${note.noteId}`)
// Create a note with tags
const note = await sdk.notes.create('notebook-id', {
title: 'Research Findings',
content: 'Important findings...',
tags: ['research', 'findings'],
})
// Create a note with just a title (add content later)
const note = await sdk.notes.create('notebook-id', {

])
```
## Language Support
NotebookLM supports **80+ languages** for artifacts, chat responses, and all notebook operations.
### Notebook Default Language
Each notebook has a **default output language** that is used for:
- Artifact creation (audio, video, report, infographics, slide decks)
- Chat responses
- All other notebook operations
**If you don't specify a language when creating an artifact, it will use the notebook's default language.**
#### Get Notebook Default Language
```typescript
// Get the current default language for a notebook
const language = await sdk.notebookLanguage.get('notebook-id');
console.log(`Default language: ${language}`); // 'en', 'de', 'ja', etc.
```
#### Set Notebook Default Language
```typescript
import { NotebookLMLanguage } from 'notebooklm-kit';
// Set the notebook's default language to German
await sdk.notebookLanguage.set('notebook-id', NotebookLMLanguage.GERMAN);
// Set to Japanese
await sdk.notebookLanguage.set('notebook-id', NotebookLMLanguage.JAPANESE);
// Set using language code directly
await sdk.notebookLanguage.set('notebook-id', 'de');
```
#### Get Language Information
```typescript
// Get language info with metadata
const info = await sdk.notebookLanguage.getInfo('notebook-id');
console.log(`Language: ${info.language}`); // 'de'
console.log(`Name: ${info.name}`); // 'German'
console.log(`Native Name: ${info.nativeName}`); // 'Deutsch'
```
### Supported Languages
Use the `NotebookLMLanguage` enum for type safety:
```typescript
import { NotebookLMLanguage } from 'notebooklm-kit'
NotebookLMLanguage.ENGLISH // 'en'
NotebookLMLanguage.HINDI // 'hi'
NotebookLMLanguage.SPANISH // 'es'
NotebookLMLanguage.FRENCH // 'fr'
NotebookLMLanguage.GERMAN // 'de'
NotebookLMLanguage.JAPANESE // 'ja'
NotebookLMLanguage.CHINESE_SIMPLIFIED // 'zh'
NotebookLMLanguage.ARABIC // 'ar'
NotebookLMLanguage.TURKISH // 'tr'
// ... and 70+ more languages
```
### Artifact Language Support
**Artifacts that support language customization:**
- ✅ **Audio Overview** - `customization.language`
- ✅ **Video Overview** - `customization.language`
- ✅ **Report** - Uses notebook default language automatically
- ✅ **Infographic** - `customization.language`
- ✅ **Slide Deck** - `customization.language`
**Artifacts that don't support language customization:**
- ❌ **Quiz** - Language is set via instructions, not customization
- ❌ **Flashcards** - Language is set via instructions, not customization
- ❌ **Mind Map** - No language customization available
### Using Language in Artifacts
#### Option 1: Use Notebook Default (Recommended)
```typescript
// Set notebook default language once
await sdk.notebookLanguage.set('notebook-id', NotebookLMLanguage.GERMAN);
// All artifacts will use German by default
const audio = await sdk.artifacts.create('notebook-id', ArtifactType.AUDIO, {
// No language specified - uses notebook default (German)
});
const video = await sdk.artifacts.create('notebook-id', ArtifactType.VIDEO, {
// No language specified - uses notebook default (German)
});
```
#### Option 2: Override for Specific Artifacts
```typescript
// Set notebook default to German
await sdk.notebookLanguage.set('notebook-id', NotebookLMLanguage.GERMAN);
// Most artifacts use German
const audio = await sdk.artifacts.create('notebook-id', ArtifactType.AUDIO, {
// Uses German (notebook default)
});
// But this one uses Japanese
const video = await sdk.artifacts.create('notebook-id', ArtifactType.VIDEO, {
customization: {
language: NotebookLMLanguage.JAPANESE, // Overrides notebook default
},
});
```
#### Option 3: Explicit Language for Each Artifact
```typescript
// Always specify language explicitly
const audio = await sdk.artifacts.create('notebook-id', ArtifactType.AUDIO, {
customization: {
language: NotebookLMLanguage.SPANISH,
},
});
const video = await sdk.artifacts.create('notebook-id', ArtifactType.VIDEO, {
customization: {
language: NotebookLMLanguage.FRENCH,
},
});
```
### Language Examples
```typescript
import { NotebookLMLanguage } from 'notebooklm-kit';
// Create artifacts in different languages
const germanAudio = await sdk.artifacts.create('notebook-id', ArtifactType.AUDIO, {
customization: {
language: NotebookLMLanguage.GERMAN, // 'de'
},
});
const japaneseVideo = await sdk.artifacts.create('notebook-id', ArtifactType.VIDEO, {
customization: {
language: NotebookLMLanguage.JAPANESE, // 'ja'
},
});
const hindiSlides = await sdk.artifacts.create('notebook-id', ArtifactType.SLIDE_DECK, {
customization: {
language: NotebookLMLanguage.HINDI, // 'hi'
},
});
const spanishInfographic = await sdk.artifacts.create('notebook-id', ArtifactType.INFOGRAPHIC, {
customization: {
language: NotebookLMLanguage.SPANISH, // 'es'
},
});
```
## Advanced Configuration
```typescript
const sdk = new NotebookLMClient({
authToken: process.env.NOTEBOOKLM_AUTH_TOKEN!,
cookies: process.env.NOTEBOOKLM_COOKIES!,
// Enable debug logging
debug: true,
// Auto-refresh configuration
autoRefresh: {
enabled: true,
interval: 5 * 60 * 1000, // 5 minutes
},
// Retry configuration
maxRetries: 3,
// Custom headers
headers: {
'User-Agent': 'My Custom Agent',
},
})
// Manually refresh
await sdk.refreshCredentials()
// Get RPC client
const rpcClient = sdk.getRPCClient()
```
## Error Handling
```typescript
import {
NotebookLMError,
NotebookLMAuthError,
RateLimitError,
APIError,
} from 'notebooklm-kit'
try {
const quiz = await sdk.artifacts.create('notebook-id', ArtifactType.QUIZ, {
instructions: 'Create a quiz',
customization: { numberOfQuestions: 2, difficulty: 2, language: 'en' },
})
} catch (error) {
if (error instanceof NotebookLMAuthError) {
console.error('Authentication failed - refresh your cookies')
} else if (error instanceof RateLimitError) {
console.error('Rate limit exceeded:', error.message)
} else if (error instanceof APIError) {
console.error('API error:', error.message)
} else if (error instanceof NotebookLMError) {
console.error('NotebookLM error:', error.message)
}
}
```
## Best Practices
### Resource Management
**Always dispose of the SDK when done** to prevent memory leaks and stop background processes:
```typescript
import { NotebookLMClient } from 'notebooklm-kit';
async function main() {
const sdk = new NotebookLMClient();
try {
await sdk.connect();
// ... use SDK ...
} finally {
await sdk.dispose(); // Always cleanup
}
}
```
**Graceful shutdown for long-running applications:**
```typescript
// Handle process termination gracefully
process.on('SIGINT', async () => {
console.log('Shutting down...');
await sdk.dispose();
process.exit(0);
});
process.on('SIGTERM', async () => {
console.log('Terminating...');
await sdk.dispose();
process.exit(0);
});
```
### Error Handling
**Use specific error types** for better error handling:
```typescript
import {
NotebookLMError,
NotebookLMAuthError,
RateLimitError,
APIError,
} from 'notebooklm-kit';
try {
const notebook = await sdk.notebooks.create({ title: 'My Notebook' });
} catch (error) {
if (error instanceof NotebookLMAuthError) {
// Authentication failed - credentials expired or invalid
console.error('Please refresh your credentials');
// Optionally: Force re-authentication
// Set FORCE_REAUTH=true in .env or delete credentials.json
} else if (error instanceof RateLimitError) {
// Rate limit exceeded - wait before retrying
console.error('Rate limit exceeded. Please wait before retrying.');
// Implement exponential backoff
} else if (error instanceof APIError) {
// API error - check error code and message
if (error.code === 143) {
console.error('Resource not found');
} else if (error.isRetryable()) {
// Retry transient errors
console.error('Transient error, will retry:', error.message);
} else {
console.error('API error:', error.message);
}
} else if (error instanceof NotebookLMError) {
// Generic NotebookLM error
console.error('NotebookLM error:', error.message);
} else {
// Unexpected error
console.error('Unexpected error:', error);
}
}
```
**Retry logic for transient errors:**
```typescript
async function createNotebookWithRetry(title: string, maxRetries = 3) {
for (let attempt = 0; attempt < maxRetries; attempt++) {
try {
return await sdk.notebooks.create({ title });
} catch (error) {
if (error instanceof APIError && error.isRetryable() && attempt < maxRetries - 1) {
const delay = Math.pow(2, attempt) * 1000; // Exponential backoff
console.log(`Retry ${attempt + 1}/${maxRetries} after ${delay}ms...`);
await new Promise(resolve => setTimeout(resolve, delay));
continue;
}
throw error; // Re-throw if not retryable or max retries reached
}
}
}
```
### Credential Management
**Use saved credentials** for faster startup (credentials are automatically saved after first auto-login):
```typescript
// First run: Auto-login saves credentials to credentials.json
const sdk = new NotebookLMClient({
auth: {
email: process.env.GOOGLE_EMAIL!,
password: process.env.GOOGLE_PASSWORD!,
},
});
await sdk.connect(); // Saves credentials for future use
// Subsequent runs: Credentials loaded automatically from credentials.json
// No need to provide email/password again
const sdk2 = new NotebookLMClient();
await sdk2.connect(); // Uses saved credentials
```
**Force re-authentication when needed:**
```typescript
// Option 1: Set environment variable
// FORCE_REAUTH=true
// Option 2: Delete credentials.json file
// rm credentials.json
// Option 3: Explicitly provide new credentials
const sdk = new NotebookLMClient({
auth: {
email: process.env.GOOGLE_EMAIL!,
password: process.env.GOOGLE_PASSWORD!,
},
});
```
### Quota Management
**Check quota before operations** to avoid rate limit errors:
```typescript
// Check remaining quota
const remainingChats = sdk.getRemaining('chats');
if (remainingChats <= 0) {
console.warn('No chat quota remaining. Please wait or upgrade plan.');
return;
}
// Use chat
const response = await sdk.generation.chat(notebookId, 'Your question');
```
**Monitor usage:**
```typescript
const usage = sdk.getUsage();
console.log(`Notebooks: ${usage.notebooks.used}/${usage.notebooks.limit}`);
console.log(`Chats: ${usage.chats.used}/${usage.chats.limit}`);
console.log(`Sources: ${usage.sources.used}/${usage.sources.limit}`);
```
### Source Processing
**Wait for sources to process** before creating artifacts:
```typescript
// Add source
const sourceId = await sdk.sources.add.url(notebookId, {
url: 'https://example.com/article',
});
// Wait for processing to complete
let status = await sdk.sources.status(notebookId);
while (status.sources.find(s => s.sourceId === sourceId)?.state !== 'READY') {
await new Promise(resolve => setTimeout(resolve, 2000)); // Wait 2 seconds
status = await sdk.sources.status(notebookId);
}
// Now create artifact (source is ready)
const quiz = await sdk.artifacts.create(notebookId, ArtifactType.QUIZ);
```
### Artifact State Checking
**Check artifact state** before downloading or using:
```typescript
// Create artifact
const artifact = await sdk.artifacts.create(notebookId, ArtifactType.QUIZ);
// Wait for artifact to be ready
let currentArtifact = artifact;
while (currentArtifact.state !== ArtifactState.READY) {
if (currentArtifact.state === ArtifactState.FAILED) {
throw new Error('Artifact generation failed');
}
await new Promise(resolve => setTimeout(resolve, 2000)); // Wait 2 seconds
currentArtifact = await sdk.artifacts.get(artifact.artifactId, notebookId);
}
// Now download or use the artifact
const quizData = await sdk.artifacts.download(artifact.artifactId, './downloads', notebookId);
```
### Async/Await Patterns
**Use async/await consistently** for better error handling:
```typescript
// ✅ Good: Proper async/await
async function processNotebook(notebookId: string) {
try {
const sources = await sdk.sources.list(notebookId);
const artifacts = await sdk.artifacts.list(notebookId);
return { sources, artifacts };
} catch (error) {
console.error('Failed to process notebook:', error);
throw error;
}
}
// ❌ Avoid: Mixing promises and async/await
function processNotebookBad(notebookId: string) {
sdk.sources.list(notebookId).then(sources => {
// Error handling is harder here
});
}
```
### Connection Lifecycle
**Connect once, reuse the SDK instance:**
```typescript
// ✅ Good: Connect once, reuse
const sdk = new NotebookLMClient();
await sdk.connect();
// Use SDK multiple times
const notebooks = await sdk.notebooks.list();
const sources = await sdk.sources.list(notebookId);
const artifacts = await sdk.artifacts.list(notebookId);
await sdk.dispose(); // Cleanup when done
// ❌ Avoid: Connecting multiple times
// Don't call connect() multiple times - reuse the same instance
```
### Debug Mode
**Enable debug mode for troubleshooting:**
```typescript
// In development
const sdk = new NotebookLMClient({
debug: process.env.NODE_ENV === 'development',
});
// Or via environment variable
// NOTEBOOKLM_DEBUG=true
// Debug mode shows:
// - RPC call details
// - Authentication flow
// - Auto-refresh operations
// - Error details
// - Response parsing
```
### Batch Operations
**Use batch operations** when adding multiple sources:
```typescript
// ✅ Good: Batch add sources
await sdk.sources.add.batch(notebookId, {
sources: [
{ type: 'url', url: 'https://example.com/1' },
{ type: 'url', url: 'https://example.com/2' },
{ type: 'url', url: 'https://example.com/3' },
],
});
// ❌ Avoid: Adding sources one by one
// This is slower and uses more API calls
```
### Streaming Responses
**Use streaming for long responses** to show progress:
```typescript
// Stream chat response for better UX
const stream = await sdk.generation.chatStream(notebookId, 'Long question...');
for await (const chunk of stream) {
if (chunk.type === 'content') {
process.stdout.write(chunk.content); // Show progress
} else if (chunk.type === 'citations') {
console.log('\nCitations:', chunk.citations);
}
}
```
### Environment Variables
**Use environment variables** for configuration:
```typescript
// ✅ Good: Use .env file
// .env
NOTEBOOKLM_AUTH_TOKEN=...
NOTEBOOKLM_COOKIES=...
NOTEBOOKLM_DEBUG=true
// ❌ Avoid: Hardcoding credentials
const sdk = new NotebookLMClient({
authToken: 'hardcoded-token', // Don't do this!
});
```
### Recommended Patterns
**Complete example with best practices:**
```typescript
import { NotebookLMClient, ArtifactType, ArtifactState } from 'notebooklm-kit';
import dotenv from 'dotenv';
dotenv.config();
async function main() {
const sdk = new NotebookLMClient({
debug: process.env.NOTEBOOKLM_DEBUG === 'true',
});
try {
await sdk.connect();
// Check quota before operations
const remaining = sdk.getRemaining('chats');
if (remaining <= 0) {
console.warn('No chat quota remaining');
return;
}
// Create notebook
const notebook = await sdk.notebooks.create({
title: 'Research Project',
emoji: '📚',
});
// Add source and wait for processing
const sourceId = await sdk.sources.add.url(notebook.projectId, {
url: 'https://example.com/article',
});
// Wait for source to be ready
let status = await sdk.sources.status(notebook.projectId);
while (status.sources.find(s => s.sourceId === sourceId)?.state !== 'READY') {
await new Promise(resolve => setTimeout(resolve, 2000));
status = await sdk.sources.status(notebook.projectId);
}
// Create artifact and wait for completion
const artifact = await sdk.artifacts.create(
notebook.projectId,
ArtifactType.QUIZ,
{
customization: {
numberOfQuestions: 10,
difficulty: 2,
},
}
);
// Wait for artifact to be ready
let currentArtifact = artifact;
while (currentArtifact.state !== ArtifactState.READY) {
if (currentArtifact.state === ArtifactState.FAILED) {
throw new Error('Artifact generation failed');
}
await new Promise(resolve => setTimeout(resolve, 2000));
currentArtifact = await sdk.artifacts.get(
artifact.artifactId,
notebook.projectId
);
}
// Download artifact
const quizData = await sdk.artifacts.download(
artifact.artifactId,
'./downloads',
notebook.projectId
);
console.log('Success!', quizData);
} catch (error) {
console.error('Error:', error);
process.exit(1);
} finally {
await sdk.dispose(); // Always cleanup
}
}
// Graceful shutdown
process.on('SIGINT', async () => {
console.log('\nShutting down...');
process.exit(0);
});
main();
```
