Configuring JavaScript debugger

Last modified: 10 August 2022

Required plugins: Javascript and TypeScript, JavaScript Debugger

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

IntelliJ IDEA provides a built-in debugger for your client-side JavaScript code. The bult-in debugger starts automatically when you launch a debugging session.

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.
