yaschema-ws-api-client

Client supporting WebSockets via yaschema-ws-api

Basic Example

export const stream = makeWsApi({
  routeType: 'stream',
  url: '/stream',
  schemas: {
    requests: {
      ping: schema.object({ echo: schema.string().allowEmptyString().optional() }).optional()
    },
    responses: {
      pong: schema.object({
        body: schema.string()
      })
    }
  }
});

const connection = await apiWs(
  stream,
  {},
  {
    pong: async ({ input }) => {
      console.log(`GOT ${input.body}`)
    }
  }
);

await connection.output.ping({ echo: 'Hello World!' });

The above example demonstrates basic use of a yaschema-ws-api-client, which lets you define runtime and compile-time types for bidirectionally working with WebSockets. See the express-yaschema-ws-api-handler package for adding handlers to Express.

This library supports web-based WebSockets by default and supports the Node ws package by calling:

setWebSocket(WebSocket as any as CommonWebSocket);

While the Node ws WebSocket interface doesn't perfectly align with the web equivalent, for the aspects we use, it does.
