To ensure successful debugging, it is enough to specify the built-in web server port and accept the default settings that WebStorm suggests for other debugger options.
- In the Settings/Preferences dialog (Ctrl+Alt+S), click Debugger under Build, Execution, Deployment. The Debugger page opens.
- In the Built-in server area, specify the port where the built-in web server runs. By default this port is set to the default WebStorm port
63342through which WebStorm accepts connections from services. You can set the port number to any other value starting with 1024 and higher.
- Suppress calls to the files on the built-in server from other computers or from outside WebStorm by clearing the Can accept external connections or Allow unsigned requests checkbox respectively.
- Choose the way to remove breakpoints, the default setting is Click.
- On the Data Views page under the Debugger node, configure advanced debugger options: enable or disable Inline Debugging, specify when you want to see tooltips with object values and expressions evaluation results, etc.
- On the Stepping page, specify the scripts to be skipped by the debugger.
By default, the debugger does not step only into library scripts. To expand the suppression list, select Do not step into scripts checkbox and add the URL addresses to skip using the and buttons.
