Usage

The following example is a example setup you need to start a WebSocket server. By default, it’s listening on http://127.0.0.1 (or prefixed with the WebSocket protocol on ws://127.0.0.1):

import { Server } from '@hocuspocus/server'
import { SQLite } from '@hocuspocus/extension-sqlite'

const server = new Server({
  port: 1234,

  async onConnect() {
    console.log('🔮')
  },

  extensions: [
    new SQLite({
      database: 'db.sqlite',
    }),
  ],
});

server.listen();
