appwrite-webhook-restreamer

Appwrite Server SDK does not support realtime through WebSocket. Due to the limitations of automatic SDK generator, looks like It would not ever support It. I am solved that problem by using SockJS

Important

There is another project named react-declarative build especially for AppWrite Realtime development. ⭐Star and 💻Fork It on github will be appreciated

Setup

1. Start this microservice by using the next command

npx -y appwrite-webhook-restreamer

or

npm install -g appwrite-webhook-restreamer
appwrite-webhook-restreamer

2. Setup webhook in the Appwrite instance settings. Use the next POST URL: http://127.0.0.1:9999/emit

3. Listen for events by using any SockJS Client with the next url: http://127.0.0.1:9999/listen. The following code might be useful

import Socket from "sockjs-client";

import { Subject, singleshot } from "react-declarative";

...

export class RealtimeService {

  private readonly _sockjsSubject = new Subject<object>();

  private _init = singleshot(() => {
    new Socket("http://127.0.0.1:9999/listen").onmessage = (msg) => {
      const chunk = JSON.parse(msg.data);
      const data = {
        payload: chunk.payload,
        channels: [],
        events: chunk.events.split(","),
        timestamp: chusnk.timestamp,
      };
      this._sockjsSubject.next(data);
    };
  });

  subscribe = <T extends unknown>(
    channel: string,
    callback: (payload: RealtimeResponseEvent<T>) => void,
  ) => {
      this._init();
      return this._sockjsSubject.subscribe((payload) => {
        if (payload.events.some((event: string) => event.includes(channel))) {
          callback(payload);
        }
      });
  };
}

CLI

The first command line argument is always a port. The second is the disallowWs flag (optional)
