OpenCode Telegram Bot

Project: OpenCode Telegram Bot

Situation

Developers needed access to OpenCode sessions from a phone while keeping the OpenCode server separate from the messaging interface. The service also needed to support more than one server and protect development environments.

Task

Build a standalone Telegram application that connects to OpenCode servers through HTTP, streams updates to users, and manages multiple sessions and instances.

Action

Built a Node.js and TypeScript bot connecting Telegram through the Bot API and OpenCode through its HTTP API
Added session creation, switching, status, and stop commands
Implemented real-time response and status streaming
Added user whitelist authentication, rate limiting, and Redis-backed persistence with an in-memory fallback
Added multi-instance configuration for connecting to more than one OpenCode server
Added Docker Compose deployment for the bot, Redis, and an OpenCode server

Result

Created a mobile-friendly control surface for AI development sessions without coupling the bot to the OpenCode server.

Technologies

TypeScript, Node.js, Telegram Bot API, HTTP API, SSE and event streaming, Redis, Docker Compose
