Configuring JavaScript debuggerUltimate

Last modified: 09 June 2021

Required plugins: Javascript and TypeScript, JavaScript Debugger

The plugins are available only in IntelliJ IDEA Ultimate, where they are enabled by default.

Debugging JavaScript in IntelliJ IDEA is supported through the JavaScript Debugger plugin. The JavaScript Debugger plugin is bundled with IntelliJ IDEA and activated by default. If the plugin is disabled, enable it on the Installed tab of the Settings/Preferences | Plugins page, as described in Managing 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 IntelliJ IDEA suggests for other debugger options.
