Then run the following command in your terminal window to install the command-line utility. If you've previously installed gulp globally, run npm rm -global gulp before following these instructions. Once you've done that, you can install the command-line utility.įirst, a quick note as explained in the Quick Start guide for gulp:

If you don't have Node.js and npm installed, you'll need to get those first you can learn how to do that in the get npm guide. Install the command-line utility for gulpįirst, you need to open a new terminal window and install the command-line utility for gulp. I couldn't seem to find such a basic tutorial on the web that was explained in simple terms. This encompasses many things, but let's focus on a basic use case for minifying JavaScript and CSS files. To use it in other projects, select Global from the Level list.Gulp is a toolkit for automating painful or time-consuming tasks in your development workflow. Make sure the Enabled checkbox is selected.īy default, the File Watcher will be available in the current project. PhpStorm brings you back to the File Watchers page where the new File Watcher is added to the list:
Otherwise, type the path manually or click and select the file location in the dialog that opens.Īccept the default File Watcher settings or reconfigure them, if necessary, as described in File Watchers, and click OK. If you installed UglifyJS through the Node Package Manager, PhpStorm locates the package itself and fills in the field automatically with the uglifyjs alias. In the Program text box, specify the location of the UglifyJS executable file. The File Watchers page that opens shows the list of already configured File Watchers.Ĭlick or press Alt+Insert and select the UglifyJS predefined template from the list. In the Settings/Preferences dialog ( Ctrl+Alt+S), click File Watchers under Tools. Learn more from the UglifyJS official website.

The location of this generated file is defined in the Output paths to refresh field of the New Watcher dialog. The generated minified code is stored in a separate file with the name of the source JavaScript file and the extension min.js. You can specify other events that invoke UglifyJS. To compress your code automatically, you need to configure a UglifyJS File Watcher which will track changes to your files and run UglifyJS.īy default, minification starts as soon as a JavaScript file in the File Watcher's scope is changed and saved.
For ES6 and later versions, use build tools, for example, Babel or webpack. UglifyJS works only with JavaScript (ES5 and earlier). If you're not using build tools, you can use a stand-alone tool, such as UglifyJS. Most often compression is done as a step in your build process, with build tools like webpack. At the production stage, they only increase the size of code to be transferred. During development and debugging, these characters make code easier to read. Minification or compression means removing all unnecessary characters, such as spaces, new lines, comments, without changing the functionality of the source code.
