client/web/src — AffineScript Web Client +:toc: preamble + +== Purpose + +The browser-side Burble client, written in AffineScript (`.affine`). AffineScript is a resource-typed superset of ReScript that enforces linear and affine ownership at compile time — ensuring that WebRTC connections, AudioContexts, and other browser resources are created exactly once and closed properly, with no dangling handles. + +The original ReScript sources (`.res`) are kept as a fallback. The `affinec` compiler (OCaml + dune, bundled via `tools/affinescript` submodule and the `Containerfile`) compiles `.affine` to JavaScript. All 35 source files have been migrated. + +== Key files + +`Main.affine`:: Entry point. Initialises the application state as a *linear* resource (must be created once, cannot be silently dropped), sets up URL routing via `window.addEventListener("popstate", …)`, and starts the render loop. The `app` value is borrowed affinely by closures — they may be called at most once per event. + +`Audio.affine`:: Microphone capture and audio analysis. `AudioContext` and `AnalyserNode` are typed as linear/affine resources respectively, so the type system prevents them from being garbage-collected while a stream is active. Wraps the Web Audio API via `@send`/`@get`/`@new` external bindings. + +`WebRTC.affine`:: `RTCPeerConnection` lifecycle, SDP offer/answer exchange, ICE candidate handling, and data channel setup. `RTC.connection` is a linear type — the compiler ensures it is either closed or transferred, never just dropped. + +`Room.affine`:: Room state machine: joining, connected, disconnected. Coordinates `Audio`, `WebRTC`, and `Signaling` modules. Holds the list of participants as an affine value that is consumed and rebuilt on each membership change. + +`Signaling.affine`:: WebSocket connection to the Burble signaling server (`signaling/relay.js`). Typed as affine — at most one signaling connection is live per room session. + +`Bindings.affine`:: Raw JavaScript FFI declarations for browser APIs not covered by the standard AffineScript stdlib (MediaDevices, RTCSessionDescription, etc.). + +== How it fits into the system + +``` +affinec compiler + └─► .affine sources → JavaScript bundle + │ + ▼ + Browser loads bundle + └─► Main.affine entry point + ├─► Audio: getUserMedia → AudioContext → AnalyserNode + ├─► Signaling: WebSocket → signaling/relay.js + └─► WebRTC: RTCPeerConnection → SDP → ICE → Media tracks +``` + +The compiled JavaScript is served from `client/web/` alongside `p2p-voice.html`.
