Configuring JavaScript Debugger

Debugging JavaScript in JetBrains Rider is supported through the JavaScript Debugger plugin. The plugin is activated by default. If the plugin is disabled, enable it on the Plugins settings page as described in Enabling and Disabling Plugins.

Debugging of JavaScript code is supported in Google Chrome and other browsers of the Chrome family.

To ensure successful debugging, it is enough to specify the built-in web server port and accept the default settings that JetBrains Rider suggests for other debugger options.

To set the built-in web server port

1. In the Settings/Preferences dialog (Ctrl+Alt+S), click Debugger under Build, Execution, Deployment. The Debugger page opens.
2. 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 JetBrains Rider port 63342 through which JetBrains Rider accepts connections from services. You can set the port number to any other value starting with 1024 and higher.
   If the Live Edit functionality is enabled, the JetBrains Chrome extension will also use this port to connect to the running page, see Live Edit in HTML, CSS, and JavaScript for details.

Optionally

1. Suppress calls to the files on the built-in server from other computers or from outside JetBrains Rider by clearing the Can accept external connections or Allow unsigned requests checkbox respectively.
2. Choose the way to remove breakpoints, the default setting is Click.
3. On the Debugger. 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.
