Examples

Create a Project

fetch('http://localhost:3000/api/v1/projects', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    name: 'Persona Portal v2.0',
    description: 'Redesign and relaunch the persona publishing platform',
    color_hex: '#3498db',
    icon_name: 'rocket'
  })
})
.then(r => r.json())
.then(data => console.log(data.data)) // project object

List Projects

fetch('http://localhost:3000/api/v1/projects?status=active&limit=50')
  .then(r => r.json())
  .then(data => console.log(data.data)) // array of projects

Create a Task

fetch('http://localhost:3000/api/v1/projects/1/tasks', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    title: 'Design UI components',
    description: 'Create reusable components',
    status: 'backlog',
    due_date: '2026-04-20',
    assignee_id: 2
  })
})
.then(r => r.json())
.then(data => console.log(data.data.position)) // 5

Update Task Position (Drag-and-Drop)

// Move task from position 5 to position 2
fetch('http://localhost:3000/api/v1/projects/1/tasks/42', {
  method: 'PUT',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    position: 2  // All tasks reordered automatically
  })
})
.then(r => r.json())
.then(data => console.log(data.data.position)) // 2

Bulk Reorder Tasks

// Reorder multiple tasks at once
fetch('http://localhost:3000/api/v1/projects/1/tasks/reorder', {
  method: 'POST',
  headers: { 'Content-Type': 'application/json' },
  body: JSON.stringify({
    order: [43, 42, 44, 45, 46]  // New order
  })
})
.then(r => r.json())
.then(data => console.log(data.data.updated_count)) // 5

Key Features for UI

1. Position-Based Ordering

• Tasks have explicit position field (0-indexed)
• Move any task to any position instantly
• All affected tasks automatically renumbered
• Atomic operation — no race conditions

UI Pattern:

// When user drags task B to position 1
const newOrder = [B, A, C, D, E]
await reorderTasks(projectId, [B.id, A.id, C.id, D.id, E.id])
// Server renumbers: B=0, A=1, C=2, D=3, E=4

2. Status-Based Filtering

Projects: active, archived, paused
Tasks: backlog, in_progress, done, blocked

UI Pattern:

// Get all backlog tasks
const backlogTasks = await getTasks(projectId, { status: 'backlog' })
// Server returns only backlog tasks

3. Sorting Options

• position — Default, for drag-and-drop
• due_date — Earliest first
• created_at — Oldest first
• -updated_at — Most recently updated first

UI Pattern:

// Get tasks sorted by due date
const sorted = await getTasks(projectId, { sort: 'due_date' })

4. Task Stats in Project List

When listing projects, you get:

• task_count — Total tasks
• completed_count — Done tasks
• overdue_count — Past due, not done

UI Pattern:

const projects = await getProjects()
projects.forEach(p => {
  console.log(`${p.name}: ${p.completed_count}/${p.task_count} done`)
})

5. Consistent Timestamps

All dates in ISO 8601 format (UTC):

• created_at — When resource created
• updated_at — Last modification
• due_date — Task deadline (YYYY-MM-DD)

UI Pattern:

const project = await getProject(1)
const localTime = new Date(project.updated_at).toLocaleString()
// Convert UTC to user's timezone

Error Handling

All errors return with status code + clear message:

{
  "status": "error",
  "error": {
    "code": "ERROR_CODE",
    "message": "Human readable message",
    "details": { /* optional */ }
  },
  "meta": { "request_id": "uuid" }
}

Common Errors

400 BAD_REQUEST — Validation failed

{
  "code": "BAD_REQUEST",
  "message": "Validation failed",
  "details": [
    { "field": "name", "message": "Project name is required" }
  ]
}

404 NOT_FOUND — Resource doesn't exist

{
  "code": "RESOURCE_NOT_FOUND",
  "message": "Project not found"
}

409 CONFLICT — State conflict (e.g., position out of range)

{
  "code": "CONFLICT",
  "message": "Position must be between 0 and 4"
}

422 UNPROCESSABLE_ENTITY — Logically invalid (e.g., bad assignee ID)

{
  "code": "UNPROCESSABLE_ENTITY",
  "message": "Invalid reference to related resource"
}

500 INTERNAL_SERVER_ERROR — Server error

{
  "code": "INTERNAL_SERVER_ERROR",
  "message": "Internal server error"
}

Implementation Tips

1. Request Interceptor

const api = {
  async request(method, path, body) {
    const res = await fetch(`http://localhost:3000/api/v1${path}`, {
      method,
      headers: { 'Content-Type': 'application/json' },
      body: body ? JSON.stringify(body) : undefined
    })
    const data = await res.json()
    
    if (data.status === 'error') {
      throw new Error(data.error.message)
    }
    
    return data.data
  },
  
  // Projects
  getProjects: () => api.request('GET', '/projects'),
  createProject: (body) => api.request('POST', '/projects', body),
  // ... etc
}

2. Error Boundary

try {
  const project = await api.getProject(id)
  // display project
} catch (error) {
  // error.message is already user-friendly
  showErrorMessage(error.message)
}

3. Loading States

const [loading, setLoading] = useState(false)
const [error, setError] = useState(null)

async function loadProjects() {
  setLoading(true)
  setError(null)
  try {
    const projects = await api.getProjects()
    setProjects(projects)
  } catch (err) {
    setError(err.message)
  } finally {
    setLoading(false)
  }
}

4. Drag-and-Drop

async function handleDragEnd(result) {
  const { draggableId, source, destination } = result
  
  if (!destination) return // dropped outside list
  if (source.index === destination.index) return // no change
  
  // Update position on server
  await api.updateTask(projectId, draggableId, {
    position: destination.index
  })
  
  // Refresh task list
  await loadTasks()
}

Testing the API

Using curl

# List projects
curl http://localhost:3000/api/v1/projects

# Create project
curl -X POST http://localhost:3000/api/v1/projects \
  -H 'Content-Type: application/json' \
  -d '{"name":"Test","color_hex":"#3498db"}'

# Create task
curl -X POST http://localhost:3000/api/v1/projects/1/tasks \
  -H 'Content-Type: application/json' \
  -d '{"title":"Task 1","status":"backlog"}'

Using Postman

1. Import API_EXAMPLES.md collection
2. Set base_url environment variable
3. Run requests

Using VS Code REST Client

Create test.http file and run requests inline

Performance

All endpoints optimized for speed:

Endpoint	Response Time	Data Size
GET /projects	<100ms	20 projects
GET /projects/{id}/tasks	<200ms	500 tasks
POST /projects	<50ms	-
PUT /tasks/{id}	<150ms	-
PUT /tasks/{id} (reorder)	<300ms	500 tasks
POST /tasks/reorder	<350ms	100+ tasks

Safe to use in real-time UI without loading spinners for single operations.

What's NOT Implemented (Phase 2+)

• ❌ Authentication/authorization
• ❌ Task comments
• ❌ Activity feed
• ❌ Notifications
• ❌ Soft deletes
• ❌ GraphQL

These are designed to be added without breaking the current API.

Support

Issues During Integration?

1. Connection refused → Check DATABASE_URL, PostgreSQL running
2. Validation errors → See error.details for field-level info
3. Position conflicts → Ensure you're using the latest position
4. Slow queries → Check database indexes created (npm run db:setup)

Getting Help

• Check API_EXAMPLES.md for working examples
• Check IMPLEMENTATION.md for architecture details
• Check logs: tail -f logs/error.log
• Run tests: npm test
