Live-Tracking — Express Server

Minimal Express.js server scaffold.

Quick start

1. Install dependencies

npm install

2. Run server

npm start

For development with auto-reload (requires nodemon):

npm run dev

Endpoints:

• GET / — health/status
• GET /health — 200 OK
• POST /echo — echoes posted JSON

Tracking endpoints (in-memory store):

• GET /locations — list all locations
• POST /locations — create a location
  • Body JSON: { "userId": "<string>", "lat": <number>, "lng": <number>, "timestamp": "<ISO string (optional)>" }
  • Example:

curl -X POST http://localhost:3000/locations \
  -H "Content-Type: application/json" \
  -d '{"userId":"user-123","lat":37.78,"lng":-122.41}'

• GET /locations/:id — get location by id
• PUT /locations/:id — update location (same body as POST)
• DELETE /locations/:id — delete location
• GET /users/:userId/locations — list locations for a specific user
