Run/debug configurations dialog

Run | Edit Configurations

Grouped run configurations

Use this dialog to create, edit, adjust, or remove run/debug configurations, as well as to configure the default templates that will apply to all newly created run/debug configurations.

Project configurations are grouped by configuration types; the default configuration templates are grouped under the Templates node in the left-hand part of the dialog.


Under the Templates node in the tree view of run configurations, you can select a run configuration template and edit its default settings. This will not affect the existing configurations but will be used as defaults when creating new configurations of the corresponding type.

When you select the Templates node itself, WebStorm opens the Configurations available in Run Services hidden area.

Configurations available in ServicesIn this area, create a list of run configurations that will be available in the Services tool window where you can execute and manage multiple run/debug configurations.
Confirm rerun with process termination

The behavior of this checkbox depends on whether the Single instance only option is selected for a particular run/debug configuration.

  • If this checkbox is selected, in case of a single instance, launching a new process (for example, by clicking Run on the main toolbar) while another process is still running, results in showing a dialog prompting to terminate the current process before launching a new one.

  • If this checkbox is not selected (or in case of multiple instances), WebStorm starts the new process silently.

Temporary configurations limitSpecify the maximum number of temporary configurations to be stored and shown in the Select Run/Debug Configuration list.


The tree view of run/debug configurations has a toolbar that helps you manage configurations available in your project as well as adjust default configurations templates.

Method up/ Method downAlt+Up/ Alt+Down

The order of configurations in the list defines the order, in which the configurations appear when you choose a run/debug configuration.

Default templates of run/debug configurations are always sorted alphabetically.

Move into new folder / Create new folderMove into new folder / Create new folder

You can group run/debug configurations by placing them into folders.

To create a folder, select the configurations within a category, click Folder, and specify the folder name. If only a category is in focus, an empty folder is created.

Then, to move a configuration into a folder, between the folders, or out of a folder, use drag it to the desired location or click Move Up/ Move Down.
