Notion-to-MD
(Notion to Markdown)
Notion-to-MD is a Node.js package that allows you to convert Notion pages to Markdown format.
Convert notion pages, blocks and list of blocks to markdown (supports nesting) using notion-sdk-js
## Install
```Bash
npm install notion-to-md
```
## Usage
> ⚠️ **Note:** Before getting started, create [an integration and find the token](https://www.notion.so/my-integrations).
> Details on methods can be found in [API section](https://github.com/souvikinator/notion-to-md#api)
> ⚠️ **Note:** Starting from v2.7.0, `toMarkdownString` no longer automatically saves child pages.
> Now it provides an object containing the markdown content of child pages.
## converting markdown objects to markdown string
This is how the notion page looks for this example:
```javascript
const { Client } = require("@notionhq/client");
const { NotionToMarkdown } = require("notion-to-md");
const fs = require('fs');
// or
// import {NotionToMarkdown} from "notion-to-md";
const notion = new Client({
auth: "your integration token",
});
// passing notion client to the option
const n2m = new NotionToMarkdown({ notionClient: notion });
(async () => {
const mdblocks = await n2m.pageToMarkdown("target_page_id");
const mdString = n2m.toMarkdownString(mdblocks);
console.log(mdString.parent);
})();
```
## Separate child page content
**parent page content:**
**child page content:**
`NotionToMarkdown` takes second argument, `config`
```javascript
const { Client } = require("@notionhq/client");
const { NotionToMarkdown } = require("notion-to-md");
const fs = require('fs');
// or
// import {NotionToMarkdown} from "notion-to-md";
const notion = new Client({
auth: "your integration token",
});
// passing notion client to the option
const n2m = new NotionToMarkdown({
notionClient: notion,
config:{
separateChildPage:true, // default: false
}
});
(async () => {
const mdblocks = await n2m.pageToMarkdown("target_page_id");
const mdString = n2m.toMarkdownString(mdblocks);
console.log(mdString);
})();
```
**Output:**
`toMarkdownString` returns an object with target page content corresponding to `parent` property and if any child page exists then it's included in the same object.
User gets to save the content separately.
## Disable child page parsing
```javascript
...
const n2m = new NotionToMarkdown({
notionClient: notion,
config:{
parseChildPages:false, // default: parseChildPages
}
});
...
```
## converting page to markdown object
**Example notion page:**
```js
const { Client } = require("@notionhq/client");
const { NotionToMarkdown } = require("notion-to-md");
const notion = new Client({
auth: "your integration token",
});
// passing notion client to the option
const n2m = new NotionToMarkdown({ notionClient: notion });
(async () => {
// notice second argument, totalPage.
const x = await n2m.pageToMarkdown("target_page_id", 2);
console.log(x);
})();
```
**Output:**
```json
[
{
"parent": "# heading 1",
"children": []
},
{
"parent": "- bullet 1",
"children": [
{
"parent": "- bullet 1.1",
"children": []
},
{
"parent": "- bullet 1.2",
"children": []
}
]
},
{
"parent": "- bullet 2",
"children": []
},
{
"parent": "- [ ] check box 1",
"children": [
{
"parent": "- [x] check box 1.2",
"children": []
},
{
"parent": "- [ ] check box 1.3",
"children": []
}
]
},
{
"parent": "- [ ] checkbox 2",
"children": []
}
]
```
## converting list of blocks to markdown object
```js
const { Client } = require("@notionhq/client");
const { NotionToMarkdown } = require("notion-to-md");
const notion = new Client({
auth: "your integration token",
});
// passing notion client to the option
const n2m = new NotionToMarkdown({ notionClient: notion });
(async () => {
// get all blocks in the page
const { results } = await notion.blocks.children.list({
block_id,
});
//convert to markdown
const x = await n2m.blocksToMarkdown(results);
console.log(x);
})();
```
**Output**: same as before
## Converting a single block to markdown string
- only takes a single notion block and returns corresponding markdown string
- nesting is ignored
- depends on @notionhq/client
```js
const { NotionToMarkdown } = require("notion-to-md");
// passing notion client to the option
const n2m = new NotionToMarkdown({ notionClient: notion });
const result = n2m.blockToMarkdown(block);
console.log(result);
```
**result**:
```
```
## Custom Transformers
You can define your own custom transformer for a notion type, to parse and return your own string.
`setCustomTransformer(type, func)` will overload the parsing for the giving type.
```ts
const { NotionToMarkdown } = require("notion-to-md");
const n2m = new NotionToMarkdown({ notionClient: notion });
n2m.setCustomTransformer("embed", async (block) => {
const { embed } = block as any;
if (!embed?.url) return "";
return `
${await n2m.blockToMarkdown(embed?.caption)}
`;
});
const result = n2m.blockToMarkdown(block);
// Result will now parse the `embed` type with your custom function.
```
**Note** Be aware that `setCustomTransformer` will take only the last function for the given type. You can't set two different transforms for the same type.
You can also use the default parsing by returning `false` in your custom transformer.
```ts
// ...
n2m.setCustomTransformer("embed", async (block) => {
const { embed } = block as any;
if (embed?.url?.includes("myspecialurl.com")) {
return `...`; // some special rendering
}
return false; // use default behavior
});
const result = n2m.blockToMarkdown(block);
// Result will now only use custom parser if the embed url matches a specific url
```
