With WebStorm, you can run Grunt tasks from tasks trees in the dedicated Grunt tool window, or using a Grunt run configuration, or as a before-launch task. WebStorm shows the result of executing a task 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
Make sure you have Node.js on your computer.
To use Grunt in a WebStorm project, you need two packages:
A globally installed grunt-cli package (Grunt command-line interface) for executing Grunt commands.
A grunt package installed as development dependency to build the project tasks tree and provide coding assistance while editing the Gruntfile.js or Gruntfile.coffee file. Learn more about Gruntfile.js from the Grunt official website.
Install grunt-cli globally
In the embedded Terminal (Alt+F12) , type:
npm install -g grunt-cli
Install Grunt in a project
In the embedded Terminal (Alt+F12) , type:
npm install grunt --save-dev
Running Grunt tasks from the tasks tree
WebStorm lets you run Grunt tasks easily and fast right from the tasks tree in the Grunt tool window. WebStorm automatically creates a temporary run configuration which you can save and use later, if necessary.
Open the Grunt tool window
When you build a tree of tasks for the first time during a WebStorm session, 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 from the context menu.
Build a tree of tasks from the Grunt tool window
In the Grunt tool window, click on the toolbar and choose the required Gruntfile.js file from the list. By default, WebStorm 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. WebStorm 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.
Re-build a tree
Switch to the required node and click on the toolbar.
Sort the tasks in a tree by their names
Click on the toolbar, choose Sort by from 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).
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> from the context menu.
Note that when you run tasks from a tasks tree, the force execution and verbose mode options are not available. As a result, you cannot configure WebStorm, for example, to ignore warnings or provide a detailed log. To use these options, run tasks or targets from a run configuration as described in Running and debugging tasks according to a run configuration below.
Run the default task
Select the root node in the tree, and choose Run default from the context menuu of the selection.
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 from the context menu of the selection.
Jump to the definition of a task or a target
Select the required task or target in the tree, and choose Jump to source from the context menu of the selection.
Running and debugging tasks according to a run configuration
Besides using temporary run configurations that WebStorm creates automatically when you run tasks or targets from tasks tress, you can create and launch your own Grunt.js run configurations.
Create a Grunt.js run/debug configuration
From the main menu, select Edit Configurations from the list on the toolbar.. Alternatively, select
In the Edit Configurations dialog that opens, click the Add button () on the toolbar and select Grunt.js from the 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.js file where these tasks are defined, and the path to the globally installed grunt-cli package.
Specify the Node.js interpreter to use.
If you choose the Project alias, WebStorm will automatically use the project default interpreter from the Node interpreter field on the Node.js page . In most cases, WebStorm detects the project default interpreter and fills in the field itself.
You can also choose another configured local or remote interpreter or click and configure a new one.
See Configuring remote Node.js interpreters, Configuring a local Node.js interpreter, and Using Node.js on Windows Subsystem for Linux for details.
Optionally specify the Node.js-specific option parameters and the environment variables to be passed to Node.js.
Run the tasks
Select the newly created configuration from the Select run/debug configuration list on the toolbar and click the Run button () next to the list. WebStorm displays the task output in the Run tool window.
Debug the tasks
Create a Grunt.js run/debug configuration as described above.
Open the Gruntfile.js file 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 toolbar and click next to the list or selectfrom the main menu.
In the Debug tool window that opens, analyze the suspended task execution, step through the task, and so on, as described in Examine suspended program and Step through the program.
Run a Grunt task as a before-Launch task
Open the Run/debug configurations dialog dialog by selecting from 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 that opens, click in the Before launch area and choose Run Grunt task from the list.
In the Grunt task dialog 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.
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 dialog (Ctrl+Alt+S), go to .
On the Startup Tasks page that opens, click on the toolbar.
From the 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 page that opens. When you save the new configuration it is automatically added to the list of startup tasks.
