Integrating a minification tool with WebStorm
To use a minifier in WebStorm, you need to configure it as a File Watcher. For each supported minifier, WebStorm provides a predefined File Watcher template. To run a minifier in your project, create a project-specific File Watcher based on the relevant template.
- Open the File Watchers page by choosing for Windows and Linux or for macOS.
- Click and choose the tool-specific File Watcher template from the list:
- In the New Watcher Dialog that opens, specify the path to the relevant executable file or
.jararchive in the Program field:
compiler.jarfor Closure Compiler.
yuicompressor-<version>.jarfor YUI Compressor JS.
- Optionally, customize the behaviour of the File Watcher.
- Make sure the checkbox next to the File Watcher is selected, which indicates that the File Watcher is enabled.
