Express API Server Implementation Summary

Overview

We successfully implemented a production-ready Express REST API server for the Stream Workflow Status MCP service. The API serves both REST endpoints and the React dashboard.

Files Created

API Server (/var/home/viky/Code/packages/src/@mcp/mcp-stream-workflow-status/src/api/)

1. server.ts - Main Express application

   • CORS middleware
   • JSON body parser
   • Route mounting
   • Static file serving for dashboard
   • SPA fallback for client-side routing

2. routes/streams.ts - Stream endpoints

   • GET /api/streams - List all streams with filters
   • GET /api/streams/:id - Get single stream

3. routes/commits.ts - Commit endpoints

   • GET /api/commits - Get recent commits with filters

4. routes/stats.ts - Statistics endpoints

   • GET /api/stats - Get quick dashboard statistics

Database Enhancements

Enhanced query functions in /src/database/queries/:

• streams.ts

  • getAllStreams() - Added optional status/category filters
  • getStream() - Alias for getStreamById()

• commits.ts

  • getRecentCommits() - Get N most recent commits
  • getStreamCommits() - Get commits for specific stream with limit

Documentation

• API.md - Comprehensive API documentation with examples
• test-api.sh - Test script for validating endpoints

Configuration

• Updated package.json with new scripts:
  • pnpm start - Start server
  • pnpm start:api - Start with API enabled
  • pnpm test:api - Run API tests
  • pnpm dev:api - Development with hot reload

API Endpoints

All endpoints are served at http://localhost:3001/api/

GET /api/streams

• Query params: status, category, priority
• Returns: { streams: Stream[], total: number }

GET /api/streams/:id

• Path param: id (stream identifier)
• Returns: Stream object or 404

GET /api/commits

• Query params: limit, streamId
• Returns: { commits: Commit[], total: number }

GET /api/stats

• No params
• Returns: QuickStats object

Server Configuration

Environment variables:

• API_ENABLED - Enable/disable API server (default: false)
• API_PORT - Port to listen on (default: 3001)

Integration

The API server starts automatically when API_ENABLED=true:

// In src/server.ts
import { startApiServer } from './api/server.js';

if (config.API_ENABLED) {
  startApiServer();
}

Testing

Test the API:

# Using test script
./test-api.sh

# Manual testing
curl http://localhost:3001/api/stats | jq '.'
curl http://localhost:3001/api/streams?status=active | jq '.'
curl http://localhost:3001/api/commits?limit=10 | jq '.'

Dashboard Access

The React dashboard is served at:

http://localhost:3001/

All non-API routes fall back to the dashboard for SPA routing.

Build Output

Compiled files in /dist/api/:

dist/api/
├── routes/
│   ├── commits.js
│   ├── stats.js
│   └── streams.js
└── server.js

Code Quality

• Full TypeScript type safety
• Proper error handling with try/catch
• JSDoc comments on all routes
• Clean separation of concerns
• RESTful API design

Next Steps

1. Build the React dashboard that will consume this API
2. Add WebSocket support for real-time updates
3. Add authentication/authorization if needed
4. Set up production CORS configuration
