Engine Web

The web engine provides a connector for Iframe & Websocket. npm install @remix-project/engine-web

Iframe

The iframe connector is used to load & connect a plugin inside an iframe. Iframe based plugin are webview using an index.html as entry point & need to use @remix-project/plugin-iframe.

const myPlugin = new IframePlugin({
  name: 'my-plugin',
  url: 'https://my-plugin-path.com',
  methods: ['getData']
})
engine.register(myPlugin);
// This will create the iframe with src="https://my-plugin-path.com"
await manager.activatePlugin('my-plugin');
const data = manager.call('my-plugin', 'getData');

Communication between the plugin & the engine uses the window.postMessage() API.

Websocket

The websocket connector wraps the native Websocket object from the Web API. Websocket based plugin are usually server with a Websocket connection open. Any library can be used, remix-project provide a wrapper around the ws library : @remix-project/plugin-ws.

const myPlugin = new WebsocketOptions({
  name: 'my-plugin',
  url: 'https://my-server.com',
  methods: ['getData']
}, {
  reconnectDelay: 5000 // Time in ms to wait to reconnect after a disconnection 
});
engine.register(myPlugin);
// This will open a connection with the server. The server must be running first.
await manager.activatePlugin('my-plugin');
const data = manager.call('my-plugin', 'getData');
