JetBrains Rider brings you back to the File Watchers page where the new File Watcher is added to the list: Then select the new scope from the Scopes list.Īccept the other default File Watcher settings or reconfigure them, if necessary, as described in File Watchers, and click OK. To avoid minification of already minified files, configure a custom scope with the file:*js&!file:*.min.* pattern, as described in Define a new scope. Otherwise, type the path manually or click and select the file location in the dialog that opens.īy default, the Scope field shows Project Files. If you installed UglifyJS through the Node Package Manager, JetBrains Rider locates the package itself and fills in the field automatically with the uglifyjs alias. In the Program field, 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 ( Control+Alt+S), click File Watchers under Tools. Learn more from the UglifyJS official website.

Make sure the File Watchers bundled plugin is enabled in the settings. In the search field, type JavaScript and TypeScript. Make sure the JavaScript and TypeScript bundled plugin is enabled in the settings. Make sure you have Node.js on your computer. To change this default presentation, configure file nesting in the Project tool window. However, in the Project Tree, the file with the minified code is shown under the source JavaScript file which is displayed as a node. 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 install UglifyJS and configure a UglifyJS File Watcher which will track changes to your files and run the tool.īy default, minification starts as soon as a JavaScript file in the File Watcher's scope is changed and saved. Example: Compressing JavaScript with UglifyJS For ES6 and later versions, use build tools, for example, Babel or webpack. UglifyJS works only with JavaScript (ES5 and earlier). You can install another minification tool and configure it following the steps from the example below. The example only illustrates the workflow. The example below shows how you can use UglifyJS to minify your JavaScript code right from JetBrains Rider. However, in the Project Tree, the file with the minified code is shown under the source Javascript file which is displayed as a node.

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. ![]()
