# Allow the Bazel server to check directory sources for changes. Ensures that the Bazel server

# Recommended when using
# [copy_directory](https://github.com/aspect-build/bazel-lib/blob/main/docs/copy_directory.md) and
# [rules_js](https://github.com/aspect-build/rules_js) since npm package are source directories
