@bridgething/extension

The client a bridgething extension uses to talk to its host. An extension is a Deno process the bridgething desktop app runs beside a webapp.

bun add @bridgething/extension

import { asJson, defineExtension, json } from '@bridgething/extension';

defineExtension({
  start(ctx) {
    ctx.on('device', e => ctx.log.info(e.type, e.device.name));
    ctx.on('message', (device, message) =>
      device.send(json({ echo: asJson(message) })),
    );
  },
});

Register listeners synchronously in start; the host replays connected devices as soon as start runs. The host protocol owns stdin and stdout, so console.log corrupts it. Log with ctx.log.

Scaffold a webapp with an extension:

bun create bridgething my-app --extension
