The dev command starts a development server that watches your BAML source files for changes and automatically reloads the BAML runtime. This feature is designed to streamline the development process by providing real-time updates as you modify your BAML configurations.

Usage

baml-cli dev [OPTIONS]

Details

See the serve command for more information on the arguments.

The dev command performs the exact same functionality, but it additionally:

  1. Watches the BAML source files for changes.
  2. Automatically reloads the server when changes are detected.
  3. Automatically runs any generators when changes are detected.
