BinaryJS is a Node.js library that provides easy binary websocket streaming between a Node server and browser clients. It wraps websocket connections with a BinaryPack serialization layer and stream abstractions so developers can send binary data like audio, video, or TypedArrays in realtime.

Use cases

• stream binary data over websockets from node to the browser
• send audio or video chunks in realtime over a websocket connection
• transmit TypedArrays and binary blobs between server and client
• build a realtime binary data channel for a web app
• pipe node streams to browser clients over websockets
• serialize and stream structured binary messages in javascript

When to choose

• you need low-overhead binary transport over websockets in a Node.js app
• you want stream semantics (pipe, backpressure) on top of websockets
• you are sending TypedArrays, Blobs, or other binary payloads between server and browser

When to avoid

• you only need plain text or JSON messaging - native websockets or Socket.IO are simpler
• you need a actively maintained library with recent security patches - development has been dormant
• you need production-grade reconnection, fallbacks, or broad protocol support beyond basic websocket streaming
