![]() 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. If you want to learn about the concepts behind it, you can read more in the output section. 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 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. 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. Detailed Explanation of a Simple Module BundlerĪn entry point indicates which module webpack should use to begin building out its internal dependency graph.This document is intended to give a high-level overview of these concepts, while providing links to detailed concept-specific use cases.įor a better understanding of the ideas behind module bundlers and how they work under the hood, consult these resources: To get started you only need to understand its Core Concepts: Nevertheless, it is incredibly configurable to better fit your needs. Since version 4.0.0, webpack does not require a configuration file to bundle your project. Learn more about JavaScript modules and webpack modules here. 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. At its core, webpack is a static module bundler for modern JavaScript applications.
