![]() Here, for example, is a sample task that makes use of three of these four functions: gulp. I will be using Gulp as a task runner because it is very developer friendly, easy to learn, and readily understandable. We'll take a look at an example that combines webpack-dev-middleware with an express server. This is used in webpack-dev-server internally, however it's available as a separate package to allow more custom setups if desired. Once the task runner is configured, all you need to do is invoke a single command in a terminal. webpack-dev-middleware is a wrapper that will emit files processed by webpack to a server. For TypeScript, you need the ts-loader npm module, in addition to the typescript npm module. This is where you tell Webpack to use a special loader to compile a file before bundling. Run the following command to initiate a new React app in a folder called heart-webpack: create-react-app heart-webpack -scripts-version 1.0. sokra Might worth adding this to the doc somewhere to save peoples time in the future :) tl dr: if you use both babeljs and react-hot loader, put react-hot loader before babeljs, otherwise when uglifying the source you will run into er. The key part of for transpilers is the les option. HOW TO RUN WEBPACK BUILD SEQUENCE CODEThe purpose of a task runner is to automate all of these tasks so that you can benefit from an enhanced development environment while focusing on writing your app. ls es6-modules/ food-lookup/ heart-webpack-complete/ The completed version of the code for this next section is available in heart-webpack-complete. This amounts to a significant number of tasks that have nothing to do with writing the logic of the web app itself. I have this script in my package.json: 'dev': 'webpack build -mode development -watch' When I was running the script with 'npm run dev', Webpack used to open my app in a browser window. It’s also quite common to use language preprocessors such as SASS and JSX that compile to native JS and CSS, as well as JS transpilers such as Babel, to benefit from ES6 code while maintaining ES5 compatibility.
