Gruntfile.js files, recognizing definitions of tasks and targets, shows tasks and targets in a tree view, lets you navigate between a task or a target in the tree and its definition in the
Gruntfile.js file, and supports running and debugging tasks and targets.
With JetBrains Rider, you can launch Grunt tasks in the following ways:
- From tasks trees in the dedicated Grunt tool window which opens when you invoke Grunt from a
Gruntfile.jsfile. As soon as you invoke Grunt, it starts building a tree of tasks according to the
Gruntfile.json which it was invoked. If a task has targets, the task is displayed as a node and the targets are listed under it.
- According to a dedicated run configuration, see Run/Debug Configuration: Grunt.js.
- As a before-launch task, from another run configuration.
The result of executing a task is displayed in the Run tool window. The tool window shows the Grunt output, reports the errors occurred, lists the packages or plugins that have not been found, etc. The name of the last executed task is displayed on the title bar of the tool window.
Before you start
- Install Node.js and configure it as a local Node.js interpreter.
- Install and enable the NodeJS repository plugin on the Plugins page as described in Installing, Updating and Uninstalling Repository Plugins and Enabling and Disabling Plugins.
To use Grunt in a JetBrains Rider project, you need two packages:
- A globally installed
grunt-clipackage (Grunt command line interface) for executing Grunt commands.
gruntpackage installed in the project to build the project tasks tree and provide coding assistance while editing the
Gruntfile.coffeefile. Learn more about
Gruntfile.jsfrom the Grunt Official website.
To install grunt-cli globally
Open the built-in JetBrains Rider Terminal (Ctrl+Alt+1) and type
npm install -g grunt-cli at the command prompt.
To install Grunt in a project
Open the built-in JetBrains Rider Terminal (Ctrl+Alt+1) and type
npm install grunt --save-dev at the command prompt.
Running Grunt tasks from the tasks tree
Running Grunt tasks right from the tasks tree is easy and fast, the only disadvantage of this approach is that such important additional options as force execution and verbose mode are not available in this mode. As a result, you cannot have JetBrains Rider, for example, ignore warnings or provide a detailed log.
When you build a tree of tasks for the first time during the current JetBrains Rider session, the Grunt tool window is not opened yet.
The task or target execution output will be displayed in the Run tool window. The name of the target is shown in the format
<task name>:<target name>. The tool window shows the Grunt output, reports the errors occurred, lists the packages or plugins that have not been found, etc. The name of the last executed task is displayed on the title bar of the tool window.
If the Grunt tool window is not opened yet
Select the required
Gruntfile.js file in the Project tool window or open it in the editor and choose Show Grunt Tasks on the context menu.
To build a tree of tasks from the Grunt tool window
In the Grunt tool window, on the toolbar and choose the required
Gruntfile.js file from the list. By default, JetBrains Rider shows the
Gruntfile.js file in the root of your project. If you have another
Gruntfile.js file, click Choose Gruntfile.js and select the
Gruntfile.js file you need in the dialog that opens. JetBrains Rider adds a new node with the path to the chosen
Gruntfile.js file on its title and builds a tasks tree under the new node.
To re-build a tree
Switch to the required node and click on the toolbar.
To sort the tasks in a tree by their names
Click on the toolbar, choose Sort by on the menu, and then choose Name.
By default, a tree shows the tasks in the order in which they are defined in
Gruntfile.js (option Definition order).
To run a task or a target
- Double click the task or target.
- Select the task or target in the tree and press Enter or choose Run <task name> on the context menu.
To run the default task
Select the root node in the tree, and choose Run default on the context menu of the selection.
To run several tasks or targets
Use the multiselect mode: hold Shift (for adjacent items) or Ctrl (for non-adjacent items) keys and select the required tasks or targets, then choose Run or Debug on the context menu of the selection.
To navigate to the definition of a task or a target
Select the required task or target in the tree, and choose Jump to source on the context menu of the selection.
Running and debugging tasks according to a run configuration
Besides using temporary run configurations that JetBrains Rider creates automatically, you can create and launch your own Grunt.js run configurations.
To create a Grunt.js run/debug configuration
- Choose on the main menu.
- Click on the toolbar and select Grunt.js from the pop-up list. The Run/Debug Configuration: Grunt.js dialog opens.
- Specify the name of the run configuration, the tasks to run (use blank spaces as separators), the location of the
Gruntfile.jsfile where these tasks are defined, and and the path to the globally installed
- Specify the Node.js interpreter to use, see Configuring a local Node.js interpreter for details.
To run the tasks
Select the newly created run configuration from the list on the main toolbar and click next to the list. JetBrains Rider displays the task output in the Run tool window.
To debug the tasks
- Create a Grunt.js run/debug configuration as described above.
- Open the
Gruntfile.jsfile in the editor and set the breakpoints in it where necessary.
- To start a debugging session, select the required debug configuration from the list on the main tool bar and click next to the list or choose .
- In the Debug tool window that opens, analyze the suspended task execution, step through the task, etc. as described in Examining Suspended Program and Stepping through Code.
To run a Grunt task as a Before-Launch task
- Open the Run/Debug Configurations Dialog dialog by choosing on the main menu, and select the required configuration from the list or create it anew by clicking and choosing the relevant run configuration type.
- In the dialog box that opens, click in the Before launch area and choose Run Grunt task from the drop-down list.
- In the Grunt task dialog box that opens, specify the
Gruntfile.jswhere 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
Running Grunt tasks automatically
If you have some tasks or targets that you run on a regular basis, you can add the corresponding run configurations to a list of startup tasks. The tasks will be executed automatically on the project start-up.
- In the Settings/Preferences dialog (Ctrl+Alt+S), click Startup Tasks underTools.
- On the Startup Tasks page that opens, click on the toolbar.
- From the drop-down list, choose the required Grunt run configuration. The configuration is added to the list.
If no applicable configuration is available in the project, click and choose Edit Configurations. Then define a configuration with the required settings on the Run/Debug Configuration: Grunt.js page that opens. When you save the new configuration it is automatically added to the list of startup tasks.
