Run/Debug Configuration: Gulp.js

Run | Edit Configurations | new | Gulp.js


In this dialog box, create configurations for running Gulp.js tasks.

Getting access to the Run/Debug Configuration: Gulp.js dialog

  1. Install and enable the Node.js plugin. The plugin is not bundled with JetBrains Rider, but it can be installed from the JetBrains plugin repository as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.
  2. Download and install Node.js that contains the Node Package Manager(npm).
  3. Install the Gulp package as described in Installing Gulp.js.

Gulp.js-specific configuration settings

ItemDescription
Gulpfile In this field, specify the location of the Gulpfile.js file to retrieve the definitions of the tasks from. Select the path from the drop-down list or click the browseButton button and choose the file from the dialog box that opens.
Tasks In this field, specify the tasks to run. Do one of the following:
  • To run one task, select it from the drop-down list.
  • To run several tasks, type their names in the text box using blank spaces as separators.
Arguments In this text box, specify the arguments for tasks to be executed with. Use the format --<parameter_name> <parameter_value>, for example: --env development. Learn more from the Gulp Official website.
Node interpreter In this field, specify the Node.js interpreter to use, see Configuring a local Node.js interpreter for details.
Node options In this text box, type the Node.js-specific command line options to be passed to the Node.js executable file. See Node Parameters for details.

In the default configuration, type --harmony in this text box to have JetBrains Rider build a tasks tree according to a Gulpfile.js written in ECMA6.

Technically, JetBrains Rider invokes Gulp.js and processes Gulpfile.js according to the default Gulp.js run configuration. This is done silently and does not require any steps from your side. However, if your Gulpfile.js is written in ECMA6, by default JetBrains Rider does not recognize this format and fails to build a tasks tree. To solve this problem, specify --harmony as a Node parameter of the default Gulp.js run configuration.

Gulp package In this field, specify the path to the Gulp package installed locally, under the project root. See Installing Gulp.js for details.
Environment Variables In this field, specify the environment variables for the Node.js executable file, if applicable. Click Browse browseButton.png to the right of the field and configure a list of variables in the Environment Variables dialog box, that opens:
  • To define a new variable, click Add add.png and specify the variable name and value.
  • To discard a variable definition, select it in the list and click Delete delete.png.
  • Click OK, when ready

The definitions of variables are displayed in the Environment variables read-only field with semicolons as separators. The acceptable variables are:

  • NODE_PATH: A :-separated list of directories prefixed to the module search path.
  • NODE_MODULE_CONTEXTS: Set to 1 to load modules in their own global contexts.
  • NODE_DISABLE_COLORS: Set to 1 to disable colors in the REPL.

Common options

ItemDescription
NameIn this text box, specify the name of the current run/debug configuration. This field does not appear for the default run/debug configurations.
Defaults This node in the left-hand pane of the dialog box contains the default run/debug configuration settings. Select the desired configuration to change its default settings in the right-hand pane. The defaults are applied to all newly created run/debug configurations.
Share Select this check box to make the run/debug configuration available to other team members.

The shared run/debug configurations are kept in separate xml files under .idea\runConfigurations folder, while the local run/debug configurations are kept in the .idea\workspace.xml.

This check box is not available when editing the run/debug configuration defaults.

Single instance onlyIf this check box is selected, this run/debug configuration cannot be launched more than once.

Every time a new run/debug configuration is launched, JetBrains Rider checks the presence of the other instances of the same run/debug configuration, and displays a confirmation dialog box. If you click OK in the confirmation dialog box, the first instance of the runner will be stopped, and the next one will take its place.

This makes sense when the usage of certain resources can cause conflicts, or when launching two run/debug configurations of the same type consumes too much of the CPU and memory resources.

If this check box is not selected, it is possible to launch as many instances of the runner as required. So doing, each runner will start in its own tab of the Run tool window.

Before launchSpecify which tasks must be performed before applying the run/debug configuration. The specified tasks are performed in the order they appear in the list.
ItemKeyboard shortcutDescription
add Ctrl+N Click this icon to add a task to the list. Select the task to be added:
  • Run External tool. Select this option to run an application which is external to JetBrains Rider. In the dialog that opens, select the application or applications that should be run. If the necessary application is not defined in JetBrains Rider yet, add its definition.
  • Run Another Configuration. Select this option to have another run/debug configuration executed. In the dialog that opens, select the configuration to run.

    This option is available only if you have already at least one run/debug configuration in the current project.

  • Run File Watchers. Select this option to have JetBrains Rider apply all the currently active file watchers.
  • Run Grunt task. Select this option to run a Grunt task. In the Grunt task dialog box that opens, specify the Gruntfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Grunt tool.

    Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the grunt-cli package.

  • Run Gulp task. Select this option to run a Grunt task. In the Gulp task dialog box that opens, specify the Gulpfile.js where the required task is defined, select the task to execute, and specify the arguments to pass to the Gulp tool.

    Specify the location of the Node.js interpreter, the parameters to pass to it, and the path to the gulp package.

  • Run npm Script. Select this option to execute an npm script. In the NPM Script dialog box that opens, specify the npm run/debug configuration settings.
  • Start React Native Bundler. Select this option to run the bundler automatically, as part of a running or debugging session. by default, this is done through react-native start. If your application uses Expo, you need to run the development server via the start npm task. To do that, click edit, then in the Configure React Native dialog, choose npm script and select start from the list.
  • Compile TypeScript. Select this option to run the built-in TypeScript compiler and thus make sure that all the changes you made to your TypeScript code are reflected in the generated JavaScript files. In the TypeScript Compile Settings dialog that opens, select or clear the Check errors checkbox to configure the behaviour of the compiler in case any errors are detected:
    • If the Check errors checkbox is selected, the compiler will show all the errors and the run configuration will not start.
    • If the Check errors checkbox is cleared, the compiler will show all the detected errors but the run configuration still will be launched.
  • Generate CoffeeScript Source Maps. Select this option to have the source maps for your CoffeeScript sources generated. In the dialog that opens, specify where your CoffeeScript source files are located.
  • Upload files to Remote Host. Select this option to have the application files automatically uploaded to the server according to the default server access configuration.
