A File Watcher is a WebStorm system that tracks changes to your files and runs a third-party standalone application. WebStorm provides predefined File Watcher templates for a number of such standard popular third-party tools (compilers, compressors, prettifiers, and others). You can also configure a custom File Watcher to run any other third-party tool.

File watchers have two dedicated code inspections:

  • The File watcher available inspection is run in every file where a predefined File Watcher is applicable. If the project has no relevant File Watcher configured, WebStorm suggests to add one.
  • The File watcher problems inspection is invoked by a running File Watcher and highlights errors specific for it.

The page consists of two parts:

  • A list of File Watchers available in the current project. To activate a File Watcher, select the check box next to it. If an error occurs while a File Watcher is running, the File Watcher is automatically disabled.
  • A toolbar to manage this list.
