chanx-jsTyped WebSocket clients for chanx

Generate a client from your chanx AsyncAPI schema, then use it from React, Vue, Svelte, Solid or plain JavaScript, topics included.

Typed from the schema

@chanx-js/codegen turns the AsyncAPI document chanx already serves into typed channel descriptors. Sending an inbound-only action, or forgetting an address param, is a compile error.

Topics over one socket

Subscribe to many topics over a single connection. Subscriptions are reference counted, requests are matched by ref, and everything resubscribes after a reconnect.

Sharing done right

Components on a topic channel share one socket, and one leaving never unsubscribes or cuts off another. Plain channels stay separate unless you opt in, so replies never leak between components.

Every framework, one behaviour

React, Vue, Svelte and Solid bindings are thin adapters over one shared controller, so buffering and batching behave identically everywhere.

Plain JavaScript and Node

No framework required. Await a connection, await one message, or iterate with for await. Node 22 works out of the box.

Zero runtime dependencies

The runtime ships no dependencies. Validation with zod is opt-in and only loaded when you ask for it; types-only builds carry none of it.
