Webpack
WebStorm integrates with the webpack module bundler. This support improves coding assistance in JavaScript files by taking into account webpack module resolution and resolve aliases. For webpack version 2 and later, WebStorm provides code completion and quick documentation look-up for options in webpack configuration files.
Configuring webpack in WebStorm
-
Make sure webpack is listed in the
dependencies
ordevDependencies
object of your package.json.If webpack is missing, open the embedded Terminal (Alt+F12) and type:
npm install --save-dev webpack
Create a configuration file in the project root or elsewhere (webpack official website.
). Learn more from the-
Specify the webpack configuration file to use. By default, WebStorm analyses the webpack configuration file in the root of the project.
To use another webpack configuration file, in the Settings/Preferences dialog Ctrl+Alt+S, go to and specify the location of the configuration file to use.
See also Getting Started on the webpack official website.
Editing a webpack configuration file
For webpack version 2 and later, WebStorm provides code completion and documentation look-up in the configuration object of webpack.config.js. Code completion is provided on the fly. To view documentation for a symbol, press Ctrl+Q.
Resolving modules
When you open a project or edit your webpack.config.js specified on Settings/Preferences | Languages and Frameworks | JavaScript | Webpack, WebStorm analyses the configuration in the background and, based on the received information, properly understands the project resolve roots and resolve aliases. Thanks to this understanding of the project configuration, WebStorm provides more precise code completion for imports and exported symbols in JavaScript files. As a result, everything works fine without any steps from your side.
The image below illustrates module resolution in a project where react-color
is an alias for the path './src/index.js'. WebStorm properly resolves the import from react-color
, provides navigation to it and completion for the exported symbols:
Debugging applications that use webpack
You can debug applications that use webpack same way as you debug any JavaScript client-side application, see Debugging React apps created with Create React App and Debugging Angular apps created with Angular CLI.
