Run/Debug Configuration: JavaScript Debug
Use this dialog to create a configuration to be used for debugging JavaScript in applications running on the built-in or on an external web server and for debugging Dart web applications.
WebStorm supports debugging applications running on the built-in or an external web server. Debugging can be performed only using Google Chrome and other browsers of the Chrome family. Debugging applications running on the built-in server is supported for Firefox, version 36 an higher, through the Firefox Remote debug configuration. Debugging applications running on external web servers in Firefox is not supported at all.

Browser | From this list, select Chrome or another browser from the Chrome family where your application will be debugged. For Dart applications, the Dart code will be compiled into JavaScript through the dart2js or dartdevc tool. The tool is invoked automatically when you run or debug a Dart web application. |
Ensure breakpoints are detected when loading scripts | Select this checkbox to make sure that the breakpoints in the code executed on the page load are hit immediately. Note that this may slow down initial page load. |

Common
When you edit a run configuration (but not a run configuration template), you can specify the following options:
Item | Description |
---|---|
Name | In this field, specify the name for the run/debug configuration. The name will help you identify the created configuration when you choose to edit it later, or when you invoke it, for example, from the Run popup Shift+Alt+F10. |
Share through VCS | Select this checkbox to put the run/debug configuration under version control and make it 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 . |
Allow running in parallel | If this checkbox is selected, it is possible to launch a run configuration multiple times in parallel instead of rerunning it. Each runner will start in its own tab of the Run Tool Window or Debug Tool Window. When disabled, every time a new instance of the run/debug configuration is launched, WebStorm checks the presence of the other instances of the same run/debug configuration, and displays a confirmation dialog. If you click OK in the confirmation dialog, the first instance of the runner will be stopped, and the next one will take its place. This makes sense when launching two instances of run/debug configurations of the same type consumes too much of the CPU and memory resources.. |
Toolbar
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.
Item | Shortcut | Description |
---|---|---|
Alt+Insert | Create a run/debug configuration. | |
Alt+Delete | Delete the selected run/debug configuration. Note that you cannot delete default configurations. | |
Ctrl+D | Create a copy of the selected run/debug configuration. Note that you create copies of default configurations. | |
The button is displayed only when you select a temporary configuration. Click this button to save a temporary configuration as permanent. | ||
View and edit the template (that is, the default settings) for the selected run/debug configuration. The templates are displayed under the Templates node and used for newly created configurations. | ||
/ | Alt+Up/Alt+Down | Move the selected run/debug configuration up and down in the list. 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 folder. You can group run/debug configurations by placing them into folders. To create a folder, select the configurations within a category, click , 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 or and buttons. To remove grouping, select a folder and click . | ||
Click this button to sort configurations in the alphabetical order. |
Before Launch
In this area you can specify tasks that must be performed before starting the selected run/debug configuration. The tasks are performed in the order they appear in the list.
Item | Shortcut | Description |
---|---|---|
Alt+Insert | Click this icon to add one of the following available tasks:
| |
Alt+Delete | Click this icon to remove the selected task from the list. | |
Enter | Click this icon to edit the selected task. Make the necessary changes in the dialog that opens. | |
/ | Alt+Up/Alt+Down | Click these icons to move the selected task one line up or down in the list. (The tasks are performed in the order that they appear in the list.) |
Show this page | Select this checkbox to show the run/debug configuration settings prior to actually starting the run/debug configuration. | |
Activate tool window | By default this checkbox is selected and the Run or the Debug tool window opens when you start the run/debug configuration. Otherwise, if the checkbox is cleared, the tool window isn't shown. However, when the configuration is running, you can open the corresponding tool window for it yourself by pressing Alt+4 or Alt+5. |
