Hot reload all the things! – Hacker Noon

Hot reload all the things!  #Webpack #ReactJS #JavaScript

  • js;import express from ‘express’const app = express()app.get(‘/api’, (req, res) = { res.send({ message: ‘I am a server route and can also be hot reloaded!’ })})
  • /title meta name=”description” content=”” meta name=”viewport” content=”width=device-width, initial-scale=1″ /head body div id=”root”${application}/div /body /html`res.send(html)})export default appNow runnpm run start:serverand go to http://localhost:3000/ and you will see our server rendered React component.
  • We now have server rendered React with Hot Module Replacement in addition to HMR on our regular server routes.Client side React — the final piece of the puzzleLet’s install a few more dependencies for our client;yarn add webpack-dev-server react-hot-loader@next npm-run-allFirst, let’s create our client side webpack configuration in webpack.config.client.js;const webpack = require(‘webpack’)const path = require(‘path’)module.exports = { devtool: ‘inline-source-map’, entry: [ ‘react-hot-loader/patch’, ‘webpack/hot/only-dev-server’, ‘.

Now, create a folder called “server” with two files in it; index.js and server.js.
The index.js file will server as our mounting point and server.js will be our actual application. Our project…
