Finally, the module option tells webpack how to process modules with specific rules using loaders. The output option tells webpack where to save bundle files and allows you to name the bundle file. webpack will proceed to other modules based on the entry file. For one, the entry option is the starting point for the application, where webpack begins to build a dependency graph. Let’s review some of the webpack configuration options. From the project root folder, create a file with the following configurations: const path = require('path') Let’s add the webpack configuration file to our project. If you want to use plugins or loaders, then you’ll need to use the webpack configuration file, allowing you to specify how webpack will work with your project, which files to compile, and where the output bundle file will be. It will assume that the entry point for your project is src/index.js and will output the minified and optimized result in dist/ main.js during production. Npm install -D webpack webpack-cli ts-loader webpack-dev-server> webpack configurationīy default, webpack does not need a configuration file. Next, we’ll install the webpack and ts-loader packages as dependencies in our project: npm init -y Installing TypeScript globally eliminates the need to install TypeScript each time you start a new project. To install TypeScript globally, use the command below: npm install -g typescript First, you should have TypeScript installed on your computer. They are used for compiling TypeScript modules into JavaScript, handling application styles, and even linting your code with ESLint.Ī few webpack loaders include ts-loader, css-loader, style-loader, and more we’ll discuss them later in this tutorial. Loaders tell webpack how to compile and bundle static assets. webpack cannot compile or bundle non-JavaScript files, therefore, it uses a loader.
