Watch Mode

Noun · Development

Definitions

  1. A development mode in build tools, test runners, and compilers that monitors source files for changes using filesystem events and automatically re-runs the relevant build, transpilation, or test suite when a file is saved.

    In plain English: A setting that makes your tools automatically redo their work every time you save a file, so you see results instantly.

    Example: "Run Jest in watch mode and it'll only re-run the tests affected by the files you changed."
