Server is up, sqlite database is used since we did not specify mysql or postgres.
### signup, signin, user_account and usergroup
## signup
call the signup "action" api to create a new user_account
```bash
curl 'http://localhost:6333/action/user_account/signup' -X POST \
--data-raw '{"attributes":{"email":"artpar@gmail.com","password":"artpar@gmail.com","name":"artpar@gmail.com","passwordConfirm":"artpar@gmail.com"}}'
```
On a fresh instance all actions are allowed to be executed by guests, so you shouldn't see this
```json
[
{
"Attributes": {
"message": "http error (403) forbidden and 0 more errors, forbidden",
"title": "failed",
"type": "error"
},
"ResponseType": "client.notify"
}
]
```
You should see this
```json
[
{
"ResponseType": "client.notify",
"Attributes": {
"__type": "client.notify",
"message": "Sign-up successful. Redirecting to sign in",
"title": "Success",
"type": "success"
}
},
{
"ResponseType": "client.redirect",
"Attributes": {
"__type": "client.redirect",
"delay": 2000,
"location": "/auth/signin",
"window": "self"
}
}
]
```
#### Sign in to get a JWT Bearer token
```bash
curl 'http://localhost:6336/action/user_account/signin' \
--data-raw '{"attributes":{"email":"artpar@gmail.com","password":"artpar@gmail.com"}}'
[
{
"Attributes": {
"key": "token",
"value": "eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6ImFydHBhckBnbWFpbC5jb20iLCJleHAiOjE3MjkzMjExMjIsImlhdCI6MTcyOTA2MTkyMiwiaXNzIjoiZGFwdGluLTAxOTIyOCIsImp0aSI6IjAxOTI5NDFmLTI2MGUtN2I0Ni1hMWFlLWYxMGZhZTcwMDE3OSIsIm5hbWUiOiJhcnRwYXJAZ21haWwuY29tIiwibmJmIjoxNzI5MDYxOTIyLCJzdWIiOiIwMTkyMmUxYS1kNWVhLTcxYzktYmQzZS02MTZkMjM3ODBmOTMifQ.H-GLmXCT-o7RxXrjo5Of0K8Nw5mpOOw6jgoXnd5KUxo"
},

{

},

},
{

"ResponseType": "client.notify"
},
{
"Attributes": {
"delay": 2000,
"location": "/",
"window": "self"
},
"ResponseType": "client.redirect"
}
]
```
We will use
```bash
export TOKEN=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJlbWFpbCI6ImFydHBhckBnbWFpbC5jb20iLCJleHAiOjE3MjkzMjExMjIsImlhdCI6MTcyOTA2MTkyMiwiaXNzIjoiZGFwdGluLTAxOTIyOCIsImp0aSI6IjAxOTI5NDFmLTI2MGUtN2I0Ni1hMWFlLWYxMGZhZTcwMDE3OSIsIm5hbWUiOiJhcnRwYXJAZ21haWwuY29tIiwibmJmIjoxNzI5MDYxOTIyLCJzdWIiOiIwMTkyMmUxYS1kNWVhLTcxYzktYmQzZS02MTZkMjM3ODBmOTMifQ.H-GLmXCT-o7RxXrjo5Of0K8Nw5mpOOw6jgoXnd5KUxo
```
for the rest of the api calls. This is a JWT token with following data
```json
{
"email": "artpar@gmail.com", // user email
"exp": 1729321122, // token expiry
"iat": 1729061922, // token issued at time
"iss": "daptin-019228", // token issuer (your daptin instance)
"jti": "0192941f-260e-7b46-a1ae-f10fae700179", // unique identifier for this token
"name": "artpar@gmail.com", // user name
"nbf": 1729061922, // token valid not before timestamp
"sub": "01922e1a-d5ea-71c9-bd3e-616d23780f93" // user reference id
}
```
---
So you have an account and a token to authenticate as that account. But do you need it? No.
Call to fetch all user accounts works without any authorization
```bash
curl http://localhost:6333/api/user_account
```
```json
{
"links": {
"current_page": 1,
"from": 0,
"last_page": 1,
"per_page": 10,
"to": 10,
"total": 1
},
"data": [
{
"type": "user_account",
"id": "01929429-3d8f-7e53-8f15-a663e05fb01b",
"attributes": {
"__type": "user_account",
"confirmed": 0,
"created_at": "2024-10-16T07:09:43.86360642Z",
"email": "artpar1@gmail.com",
"name": "artpar1@gmail.com",
"password": "",
"permission": 2097151,
"reference_id": "01929429-3d8f-7e53-8f15-a663e05fb01b",
"updated_at": "2024-10-16T07:09:43.863622045Z",
"user_account_id": "01929429-3d8f-7e53-8f15-a663e05fb01b"
},
"relationships": { /// ...}
}
]
}
```
And so does all the data in all other tables (eg site, cloud_store, document, usergroup).
And you can call update and delete APIs as well
(not demonstrated here, but you can try, delete the sqlite database file after you are done playing to reset it all)
As the first user, it is an option for you to leave it open or enable the multi-tier permission and becoming the Administrator
```bash
curl 'http://localhost:6336/action/world/become_an_administrator' --compressed -X POST \
-H "Authorization: Bearer $TOKEN" --data-raw '{}'
```
At this point, all other apis are locked-down and only accessible by administrator, that is you.
You want to open up few or many of actions to guests or users.
... Will be updated soon

## Self-Discoverability and Self-Management Analysis
Based on comprehensive testing of a fresh Daptin instance, here are the key findings:
### Self-Discoverability Score: 9/10
Daptin excels at self-discoverability through:
- **Comprehensive OpenAPI Documentation** at `/openapi.yaml` with detailed endpoint descriptions, parameters, and examples
- **Meta-Endpoints** for runtime discovery:
- `/api/world` - Lists all 56 available entities
- `/api/action` - Shows available actions per entity
- `/action/world/download_system_schema` - Exports complete system configuration
- **JSON:API Compliance** with consistent CRUD patterns
- **Clear Authentication Flow** with public signup/signin endpoints
### Self-Management Score: 7/10
Daptin provides good self-management capabilities:
**Strengths:**
- ✅ Dynamic entity creation via API
- ✅ Programmatic server restart (`/action/world/restart_daptin`)
- ✅ Multi-admin support via usergroups
- ✅ Schema export/import functionality
- ✅ Multiple data format exports (JSON, CSV, XML, PDF)
**Limitations:**
- ❌ Some actions restricted even for admins (generate_random_data, get_action_schema)
- ❌ Schema changes require server restart
- ❌ No built-in admin UI
### Quick Reference for New Users
#### Authentication Flow
```bash
# 1. Create user (8+ character password required)
curl -X POST http://localhost:6336/action/user_account/signup \
-H "Content-Type: application/json" \
-d '{"attributes": {"email": "admin@test.com", "password": "testpass123"}}'
# 2. Get JWT token
TOKEN=$(curl -X POST http://localhost:6336/action/user_account/signin \
-H "Content-Type: application/json" \
-d '{"attributes": {"email": "admin@test.com", "password": "testpass123"}}' \
| jq -r '.[0].Attributes.value')
# 3. Become admin (ONE-TIME ONLY!)
curl -X POST http://localhost:6336/action/world/become_an_administrator \
-H "Authorization: Bearer $TOKEN"
```
#### Common Pitfalls
- Empty API responses? Check Authorization header
- Password errors? Use 8+ characters
- Schema not updated? Restart server after changes
- 403 errors? Verify token is valid and included
### Key Insights
1. **Unique Security Model**: Before admin setup, ALL users have full access (permission: 2097151)
2. **Multi-Admin Support**: Add users to "administrators" usergroup for admin access
3. **Token Management**: JWT tokens valid for 3 days, always include `Authorization: Bearer $TOKEN`
4. **Column Types**: Extensive type system with validations (see `/server/resource/column_types.go`)
## 🔄 Real-time & Communication Features (Session 2 Deep Dive - 37% Complete)
### ✅ WebSocket Real-time (SOLUTION FOUND)
WebSocket authentication works via **query parameter**, not headers:
```bash
# WORKING WebSocket Connection
curl --include \
--no-buffer \
--header "Connection: Upgrade" \
--header "Upgrade: websocket" \
--header "Sec-WebSocket-Key: SGVsbG8sIHdvcmxkIQ==" \
--header "Sec-WebSocket-Version: 13" \
"ws://localhost:6336/live?token=$TOKEN"
```
**WebSocket Features Discovered:**
- **Pub/Sub Messaging**: Subscribe to database events and custom topics
- **Permission-Aware**: Events filtered based on user permissions
- **Distributed**: Uses Olric for cluster-wide messaging
- **Auto Topics**: One system topic per database table
**WebSocket Message Methods:**
```javascript
// Subscribe to table events
{"method": "subscribe", "attributes": {"topicName": "user_account,document"}}
// Create custom topic
{"method": "create-topicName", "attributes": {"name": "chat-room-1"}}
// Publish message
{"method": "new-message", "attributes": {"topicName": "chat-room-1", "message": "Hello!"}}
// List all topics
{"method": "list-topicName", "attributes": {}}
```
### ✅ YJS Collaborative Editing (Fully Mapped)
Real-time document collaboration with conflict resolution:
**YJS Endpoints Pattern:**
- `/live/{typename}/{referenceId}/{columnName}/yjs` - WebSocket collaboration
- `/yjs/{documentName}` - Direct YJS access
- Any `file.*` column type gets automatic YJS endpoints
**Working Example from dadadash:**
```javascript
const yjsProvider = new WebsocketProvider(
`ws://localhost:6336/live/document/${referenceId}/content/yjs?token=${token}`,
'document-room',
ydoc,
{
awareness: {
user: { name: 'User Name', color: '#ff0000' }
}
}
);
```
### ✅ SMTP Email Server (Complete Implementation)
Built on go-guerrilla with enterprise features:
**Email Infrastructure:**
- **Entities**: mail_server, mail_account, mail_box, mail
- **Security**: TLS/SSL, DKIM signing, SPF verification
- **Actions**: mail.send, aws.mail.send
- **IMAP**: Full email retrieval support
**Complete Email Setup:**
```bash
# 1. Enable SMTP
curl -X PUT http://localhost:6336/_config/backend/smtp.enable \
-H "Authorization: Bearer $TOKEN" -d '"true"'
# 2. Create mail server
curl -X POST http://localhost:6336/api/mail_server \
-H "Authorization: Bearer $TOKEN" \
-H "Content-Type: application/vnd.api+json" \
-d '{
"data": {
"type": "mail_server",
"attributes": {
"hostname": "smtp.yourdomain.com",
"is_enabled": true,
"listen_interface": "0.0.0.0:465",
"always_on_tls": true
}
}
}'
# 3. Send email
curl -X POST http://localhost:6336/action/world/mail.send \
-H "Authorization: Bearer $TOKEN" \
-d '{"attributes": {"from": "noreply@yourdomain.com", "to": ["user@example.com"], "subject": "Test", "body": "Hello!"}}'
```
### ✅ Communication Protocols (All Verified)
- **CalDAV/CardDAV**: `/caldav/*` and `/carddav/*` endpoints
- **FTP Server**: Multi-site support with cloud storage backends
- **RSS/Atom Feeds**: Auto-generation from any entity
### 📊 Session 2 Feature Count: 19/52 (37%)
**Documented Features:**
1. WebSocket server architecture
2. Pub/Sub messaging patterns
3. Permission-aware event filtering
4. Custom topic management
5. YJS collaborative editing
6. YJS document persistence
7. Multi-editor support (Quill, CodeMirror)
8. User presence/awareness
9. SMTP server implementation
10. Email entity schemas (4 tables)
11. DKIM/SPF security
12. IMAP email retrieval
13. CalDAV calendar sync
14. CardDAV contact sync
15. FTP file transfer
16. RSS feed generation
17. Atom feed support
18. JSON feed format
19. Feed configuration patterns
### 🔧 Key Learnings for Future Sessions
**WebSocket Authentication:**
- Use query parameter `?token=JWT_TOKEN` not headers
- Token validation happens during WebSocket upgrade
- Same JWT tokens from signin work perfectly
**YJS Integration:**
- Requires file-type columns (file.document, file.spreadsheet, etc.)
- Documents stored as ZIP with YJS state + plain text
- Supports real-time presence and conflict resolution
**Server Configuration:**
- Most features toggle via `/_config` API
- Some changes need server restart (actions, world schema)
- Configuration stored in database, persists across restarts
**Testing Approach:**
- Always verify configuration changes took effect
- Check multiple related endpoints for full feature validation
- Use real-world examples (dadadash) for integration patterns
## 📊 Advanced Data & Analytics Features (Session 3 Deep Dive - 52% Complete)
### ✅ Aggregation API (Fully Tested)
Powerful data aggregation with SQL-like capabilities via REST:
**Endpoint Pattern:** `/aggregate/{entityName}`
**Working Examples:**
```bash
# Group by with count
curl -X GET "http://localhost:6336/aggregate/world?group=is_hidden&column=is_hidden,count" \
-H "Authorization: Bearer $TOKEN"
# Response:
{
"data": [
{"type": "aggregate_world", "attributes": {"is_hidden": 0, "count": 60}},
{"type": "aggregate_world", "attributes": {"is_hidden": 1, "count": 1}}
]
}
# Sum with filter
curl -X GET "http://localhost:6336/aggregate/world?filter=eq(is_top_level,1)&column=count" \
-H "Authorization: Bearer $TOKEN"
```
**Aggregation Features:**
- **Functions**: count, sum(col), avg(col), min(col), max(col), first(col), last(col)
- **Filters**: eq(), not(), lt(), lte(), gt(), gte(), in(), notin(), is(), not()
- **Advanced**: group by multiple columns, having clauses, joins, time sampling
- **Methods**: Both GET (query params) and POST (JSON body) supported
### ✅ GraphQL API (Configuration Mapped)
Auto-generated GraphQL schema from database:
**Enable GraphQL (Requires Restart):**
```bash
# Method 1: Configuration API
curl -X POST http://localhost:6336/_config/backend/graphql.enable \
-H "Authorization: Bearer $TOKEN" -d 'true'
