Modeīy setting the mode parameter to either development, production or none, you can enable webpack's built-in optimizations that correspond to each environment. However, there are many use cases that are worth further exploration. Using plugins in your webpack configuration is straightforward. There are many plugins that webpack provides out of the box! Check out the list of plugins. In the example above, the html-webpack-plugin generates an HTML file for your application and automatically injects all your generated bundles into this file. The use property indicates which loader should be used to do the transforming.įilename : '', } ,.The test property identifies which file or files should be transformed.We feel this extension of the language is warranted as it allows developers to build a more accurate dependency graph.Īt a high level, loaders have two properties in your webpack configuration: One of webpack's specific features is the ability to import any type of module, e.g.css files, which may not be supported by other bundlers or task runners. Loaders allow webpack to process other types of files and convert them into valid modules that can be consumed by your application and added to the dependency graph. Out of the box, webpack only understands JavaScript and JSON files. When webpack processes your application, it internally builds a dependency graph from one or more entry points and then combines every module your project needs into one or more bundles, which are static assets to serve your content from. If you want to learn about the concepts behind it, you can read more in the output section. At its core, webpack is a static module bundler for modern JavaScript applications. The output property has many more configurable features. In case you're wondering about the path module being imported at the top, it is a core Node.js module that gets used to manipulate file paths.

In order visualise our app, we need to create an index.html file and tell webpack it’s location using the following steps: Install the html-webpack-plugin. In the example above, we use the output.filename and the output.path properties to tell webpack the name of our bundle and where we want it to be emitted to. By default, webpack will only process the index.js script in src without creating any html output. resolve (_dirname, 'dist' ) ,įilename : '', }, } You can configure this part of the process by specifying an output field in your configuration: dist folder for any other generated file. dist/main.js for the main output file and to the.

The output property tells webpack where to emit the bundles it creates and how to name these files. For example:Įntry : './path/to/my/entry/file.js', } tip src/index.js, but you can specify a different (or multiple entry points) by setting an entry property in the webpack configuration. Webpack will figure out which other modules and libraries that entry point depends on (directly and indirectly).īy default its value is.
