General

RunJS settings are organised across a number of tabs in the settings window. Open it from the app menu: RunJS > Settings on macOS, or File > Settings on Windows and Linux.

The General tab covers top-level app behaviour.

Auto Run — Code is executed as you type. When disabled, run your code manually using the keyboard shortcut or the run button in the activity bar.

Auto Log — Display the result of each top-level expression in the output pane.

Default Runtime Environment — The runtime environment used by new tabs. Choose from Browser & Node.js, Node.js, or Browser.

Default Language — The language used by new tabs. Choose from TypeScript, JavaScript, JSX, or TSX.

Confirm close — Show a confirmation dialog before closing a tab. The tab is only closed once you confirm.
