IntelliJ IDEA 2020.1 Help

Spy-js tool window

The tool window is available only when the Spy-js plugin is enabled. The plugin is not bundled with IntelliJ IDEA, but it can be installed from the JetBrains plugin repository as described in Manage plugins.

The tool window opens when you launch a run configuration of the type Spy-js or Spy-js for Node.js. As soon as the Spy-js tool captures an event, it shows the event itself, its details, and stack-traces. By clicking an event, you can open the trace file, which is a prettified source file with the script that the event launched.

The tool window consists of a common toolbar and two tabs with panes:



Tooltip and shortcut


icons actions restart


Click this button to stop the current trace session and run it again. When the session is canceled externally by clicking icons actions suspend, the button toggles to icons toolwindows toolWindowRun. Note that after the session restarts, you have to refresh the traced page in the browser to start capturing events.

icons toolwindows toolWindowRun


This button substitutes for icons actions restart if the previous trace session was canceled externally by clicking icons actions suspend. Click icons toolwindows toolWindowRun to initiate a new session. Note that after the session restarts, you have to refresh the traced page in the browser to start capturing events.

icons actions suspend


Click this button to terminate the current process externally by means of the standard shutdown script.

Clicking the button once invokes soft kill allowing the application to catch the SIGINT event and perform graceful termination (on Windows, the Ctrl+C event is emulated). After the button is clicked once, it is replaced with the Kill Process button indicating that subsequent click will lead to force termination of the application, for example on Unix SIGKILL is sent.
