JetBrains Rider 2019.2 Help

Interactive Debugger Console

The interactive Console pane shows you stack traces and everything that was logged in your code (for example, using console.*).

The Console pane is also a read-eval-print loop (REPL) so you can run JavaScript code snippets in it and interact with the page that you are currently debugging.

Run JavaScript in the Console

  1. Start typing a statement at > in the input field. As you type, JetBrains Rider suggests variants for completion.

  2. Select the relevant statement and press Enter. JetBrains Rider shows its value in the console.

Navigate to source code

  • At each line with output of console.*, JetBrains Rider 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 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 the Filter button 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().
