Webpack plugin that reloads the separated react-app on browser after your app was builded and runs the docker image to start your own app with .umd static files

Please note, that you must insert the plugin's requirements to your separated react-app

Please note, that this is works only in Linux and MacOs machine (windows 10 PRO maybe but was not tested)

Plugin required environments:

• PLT_IMAGE_PORT - port of your "watching app"
• PLT_IMAGE_NAME - docker image name that will watcher run to server files via nginx
• PLT_STREAM_SEND_PORT - the port to send web-socket messages

Insert the websocket server in the separate react-app

// webpackDevServer.config.js
const WebSocket = require('ws')

const wss = new WebSocket.Server({ port: 5010 })

module.exports = function(proxy, allowedHost) {
  return {
    // other settings
    before(app, server) { 
      // create the connection
      wss.on('connection', ws => {
        // get trigger message
        ws.on('message', message =>
          // reload page 
          server.sockWrite(server.sockets,'content-changed')
        )
      })
      
      // other settings
    },
  };
};

Example of usage

// webpack.config.js
const PlatformBuildWithWatchPlugin = require('@mihanizm56/webpack-stream-watcher');

module.exports = {
  // your config ...
  plugins: [new PlatformBuildWithWatchPlugin()]
};

The actual web-socket messager runs the command

// node_modules/@mihanizm56/webpack-stream-watcher/reload-trigger.js
const WebSocket = require('ws');

const platformPort = process.env.PLT_STREAM_SEND_PORT || 5010;

module.exports.reloadTrigger = () => {
  const ws = new WebSocket(`ws://localhost:${platformPort}`);

  ws.on('open', function open() {
    ws.send('trigger');
    ws.close();
  });
};

The Websocket signal can be used in different approaches - not only to trigger reloads !!!
