This node in the left-hand pane contains the default run/debug configuration settings. Select configuration to modify its default settings in the right-hand pane. The defaults are applied to all newly created run/debug configurations.
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.
Use the controls in this area to specify which tasks must performed before applying the run/debug configuration. The tasks are performed in the order they appear in the list. The following options are available:
(Alt+Insert): click this icon to add a task to the list. Select one of the following task types:
Run External tool: select this option to run an application that is external to WebStorm. In the dialog that opens, select the application(s) that you want to run. If the required application is not defined in WebStorm yet, add its definition (for details see Configuring Third-Party Tools and External Tools).
Run Another Configuration: select this option to execute one on the existing run/debug configuration. Choose a configuration to execute from the dialog box that opens.
If the Check errors check box is selected, the compiler will show all the errors and the run configuration will not start.
If the Check errors check box is cleared, the compiler will show all the detected errors but the run configuration still will be launched.
Run File Watcher: select this option to run the File Watchers that are active in the current project. For more information, see Using File Watchers.
Generate CoffeeScript Source Maps: select this option to generate source maps for your CoffeeScript sources. In the dialog that opens, specify the path to the folder where CoffeeScript files will be generated. For more information, see CoffeeScript.
Run Remote External tool: select this option to run a remote SSH external tool. In the dialog that opens, specify the SSH external tool that you want to run. For more information, see Remote SSH External Tools.
(Alt+Delete): click this icon to remove the selected task from the list.
(Enter): click this icon to modify the selected task. Edit the task settings in the dialog that opens.
(Alt+Up): click this icon to move the selected task up in the list.
(Alt+Down): click this icon to move the selected task down in the list.
Show this page: select this check box if you want to display the run/debug configuration settings before applying it.
Active tool window: select this option if you want the Run/Debug tool windows to be activated automatically when you run/debug your application. This option is enabled by default.
Confirm rerun with process termination
The behavior of this button depends on selecting the check box Single instance only for a particular run/debug configuration.
If this check box is selected, then, in case of a single instance, launching a new process (for example, by clicking on the main toolbar) while the other process is still running, results in showing a dialog box, where one should confirm termination of the current process and launching a new one.
If this check box is not selected (or in case of multiple instances), WebStorm starts the new process silently.
Temporary configurations limit
Specify here the maximum number of temporary configurations to be stored and shown in the Select Run/Debug Configuration drop-down list.
