Webpack
RubyMine 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 higher, RubyMine provides code completion and quick documentation look-up for options in webpack configuration files.
Before you start
- Download, install, and configure Node.js.
- Make sure the NodeJS plugin is installed and enabled. The plugin is activated by default. If the plugin is disabled, enable it on the Plugins settings page as described in Enabling and Disabling Plugins.
Configuring webpack in RubyMine
- Make sure webpack is added to package.json
Webpack should be listed in thedependencies
ordevDependencies
object ofpackage.json
.
If webpack is missing, install it
Open the built-in RubyMine Terminal (Alt+F12) and typenpm install --save-dev webpack
at the command prompt.
For details, see Getting Started on the webpack Official website. - Create a webpack configuration file
Create a configuration file in the project root or elsewhere ( ). Learn more on the webpack Official website. - Specify the webpack configuration file to use
By default, RubyMine analyses the webpack configuration file in the root of the project. To use another webpack configuration file, specify the path to it on the Webpack page ( for Windows and Linux or for macOS).
Editing a webpack configuration file
For webpack version 2 and higher, RubyMine 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, RubyMine 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, RubyMine 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'
. RubyMine 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.
