Express Data Ingest Gateway (issue #2)

[MohamedEBR]

Summary

Develop a Node.js (TypeScript) service that connects to the Jetson TCP stream, validates telemetry data, adds gateway metadata, and forwards processed frames to the WebSocket broadcaster and time-series database.

Details

The ingest service will serve as the bridge between the Jetson producer and the web clients.
It should handle reconnections, data parsing, and light transformation without blocking I/O operations.

Tasks

• Create Node.js TCP client to connect to the Jetson stream
• Implement reconnect logic and error handling
• Parse and validate incoming telemetry frames
• Add gateway timestamps and metadata to each frame
• Queue processed frames for batch insert into TimescaleDB or InfluxDB
• Expose /metrics endpoint for ingest health monitoring

Deliverable

A running Express ingest gateway that maintains persistent connection to the Jetson, pushes frames to storage, and provides metrics visibility.
