ReactDOM.render( Helloworld React!, document.getElementById( 'root')) I recommend reading the Webpack documentation when you need to evolve this file. attach the presets to the loader (most projects use. use the babel-loader for transpiling JavaScript to a suitable format loader: 'babel-loader', ignore transpiling JavaScript from node_modules as it should be that state exclude: /node_modules/, for any file with a suffix of js or jsx test: /\.jsx?$/, the filename of the JS bundle will be bundle.js filename: 'bundle.js' the output of the webpack build will be in /dist directory path: path.resolve(_dirname, 'dist'), the app entry point is /src/index.js entry: path.resolve(_dirname, 'src', 'index.js'), the output bundle won't be optimized for production but suitable for development mode: 'development', const path = require( 'path') Ĭonst HtmlWebpackPlugin = require( 'html-webpack-plugin') This is the most basic set of configuration details you should get familiar with because it acts as base for the initial setup and further customization. touch Ĭopy and paste the following code into each file: Quick note: -save-dev flag is for partitioning the dependencies into development-specific dependencies, so that they are not included in the production JavaScript bundle Step 3: Create the files Html-webpack-plugin: an extension to webpack that adds the basic index html a JavaScript transpiler to converts modern JavaScript into a production-ready version that's compatible with all browsers.īabel-loader: connects Babel to webpack's build group of commonly used Babel plugins bundled into a preset that converts modern JavaScript features into widely compatible React-specific Babel plugins that convert JSX syntax into plain old JavaScript that browsers can understand This helps use see the output of your code in the browser. Webpack-dev-server: transforms our source code and serves it on a web server as we develop it continuously. Webpack-cli: allows webpack to work with CLI commands Webpack: bundler that converts your source code into production-ready output React-dom: enables us to render the React within the browser DOM React: UI library for creating modular components Npm install -save-dev webpack webpack-cli webpack-dev-server html-webpack-plugin babel-loader what each package does: Step 2: Install React, Webpack, and Babel npm install react react-dom We can use the -y to get the basic configuration and scafolding for our Node project.
