Intro Radio

Intro Radio is GEWIS's live stream (Icecast/HLS audio and video) for the student association's introduction week, with a built-in chat between listeners and radio staff and an admin backoffice for staff to manage those conversations.

This repository is a monorepo combining what used to be two separate projects:

• frontend/ -- the Vue app listeners and staff use to watch/listen and chat (formerly GEWIS/radioweb). See frontend/README.md.
• backend/ -- the Go server behind the chat and the stream metadata API (formerly GEWIS/radiogaga). See backend/README.md.

Both READMEs cover their service in depth (environment variables, message formats, HTTP endpoints); this one focuses on running the whole thing together.

Repo layout

|-- backend/      Go WebSocket chat server + JSON stream-metadata API
|-- scripts/      dev.sh (run both services) and dev-token.mjs (auth token helper)
|-- docs/         README assets
`-- .claude/      Claude Code launch config for browser-preview tooling

Local development

Prerequisites

• Node.js 22.x with Corepack-enabled Yarn (see frontend/.yarnrc.yml)
• Go 1.24+ (see backend/go.mod)

Run both services

./scripts/dev.sh

This starts the backend on http://localhost:8080 and the frontend on http://localhost:3000 (which proxies /api/v1 and /ws to the backend -- see frontend/vite.config.mts), running yarn install first if frontend/node_modules doesn't exist yet. Output from each service is prefixed with [backend] / [frontend]. Press Ctrl+C to stop both, and their child processes, cleanly.

To run a single service on its own instead, see frontend/README.md or backend/README.md. All backend environment variables have safe local defaults -- GEWIS_SECRET and RADIO_CHAT_KEY both default to ChangeMe.

Getting a chat auth token

The chat requires an HS512-signed JWT with lidnr / given_name / family_name claims, and there's no local login flow to produce one. scripts/dev-token.mjs signs one directly, using the backend's actual default secret (read from backend/chat.go, not guessed), and prints ready-to-use URLs:

node scripts/dev-token.mjs --lidnr 1337 --given-name Ada --family-name Lovelace

Listener chat:
  http://localhost:3000/?token=eyJhbGciOiJIUzUxMiIs...

Admin / backoffice chat:
  http://localhost:3000/backoffice?token=eyJhbGciOiJIUzUxMiIs...&key=ChangeMe

Open either URL once both services are running. --lidnr, --given-name, and --family-name are optional (they default to 1234, Test, and User); set GEWIS_SECRET / RADIO_CHAT_KEY in the environment to override the source-read defaults if you're running the backend with custom secrets.

Claude Code / agent preview

.claude/launch.json wires up scripts/dev.sh as a named preview target (intro-radio) for Claude Code's browser-preview tooling, so a single preview_start call brings up both services and opens a browser tab on the frontend.

Deployment

Both services build and publish as Docker images via the shared GEWIS/actions workflows (see frontend/Dockerfile and backend/Dockerfile), triggered on pushes and releases.
