Using interactive Debugger Console

When you are debugging a Node.js application, GoLand shows two console tabs in the Debug tool window - Console and Debugger Console.

The Console tab shows the output of the node process itself, that is, everything that is written to process.stdout and process.stderr directly or is logged using console.*.
In the Debugger Console, you can run JavaScript code snippets and view the console.* messages.

Run JavaScript in the Debugger Console

Start typing a statement at > in the input field. As you type, GoLand suggests variants for completion.
Select the relevant statement and press Enter. GoLand shows its value in the console.

Navigate to source code

At each line with output of console.*, GoLand shows the name of the file and the line where it was called. Click this link to jump to the call in the source code.
The Debugger Console also shows stack traces. Click the link next to a reported problem to jump to the line of code where this problem occurred.

Filter out messages

The console shows objects in a tree view, with stack traces collapsed by default. Warnings console.warn(), errors console.error(), and info console.info() messages have different icons and background colors to make them easier to notice.

To hide log messages of specific types, click and select the severities to filter out.

Group messages

The log messages grouped using console.group() and console.groupEnd() are displayed as a tree. To show the output collapsed by default, use console.groupCollapsed().

Apply CSS styles

Use CSS and the %c marker to apply styles to log messages.
