Using interactive Debugger Console
When you are debugging a Node.js application, RubyMine shows two console tabs in the Debug tool window - Process Console and Debugger Console.
The Process 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, RubyMine suggests variants for completion.Select the relevant statement and press Enter. RubyMine shows its value in the debugger console.
RubyMine shows previews for objects, so you do not need to expand them. If you still expand an object, you get an overview of just its own properties, the
__proto__contents are hidden by default.
Navigate to source code
At each line with output of
console.*, RubyMine 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 Debugger Console tab 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()andconsole.groupEnd()are displayed as a tree. To show the output collapsed by default, useconsole.groupCollapsed().
Apply CSS styles
Use CSS and the
%cmarker to apply styles to log messages.
