javascript_sources

Generate a javascript_source target for each file in the sources field.

Backend: pants.backend.experimental.javascript

dependencies​

Iterable[str] | None
default: None

Addresses to other targets that this target depends on, e.g. ['helloworld/subdir:lib', 'helloworld/main.py:lib', '3rdparty:reqs#django'].

This augments any dependencies inferred by Pants, such as by analyzing your imports. Use pants dependencies or pants peek on this target to get the final result.

See https://www.pantsbuild.org/2.23/docs/using-pants/key-concepts/targets-and-build-files for more about how addresses are formed, including for generated targets. You can also run pants list :: to find all addresses in your project, or pants list dir to find all addresses defined in that directory.

If the target is in the same BUILD file, you can leave off the BUILD file path, e.g. :tgt instead of helloworld/subdir:tgt. For generated first-party addresses, use ./ for the file path, e.g. ./main.py:tgt; for all other generated targets, use :tgt#generated_name.

You may exclude dependencies by prefixing with !, e.g. ['!helloworld/subdir:lib', '!./sibling.txt']. Ignores are intended for false positives with dependency inference; otherwise, simply leave off the dependency from the BUILD file.

description​

str | None
default: None

A human-readable description of the target.

Use pants list --documented :: to see all targets with descriptions.

overrides​

Dict[Union[str, Tuple[str, ...]], Dict[str, Any]] | None
default: None

Override the field values for generated javascript_source targets.

Expects a dictionary of relative file paths and globs to a dictionary for the overrides. You may either use a string for a single path / glob, or a string tuple for multiple paths / globs. Each override is a dictionary of field names to the overridden value.

For example:

overrides={
    "foo.js": {"skip_prettier": True},
    "bar.js": {"skip_prettier": True},
    ("foo.js", "bar.js"): {"tags": ["no_lint"]},
}

File paths and globs are relative to the BUILD file's directory. Every overridden file is validated to belong to this target's sources field.

If you'd like to override a field's value for every javascript_source target generated by this target, change the field directly on this target rather than using the overrides field.

You can specify the same file name in multiple keys, so long as you don't override the same field more than one time for the file.

skip_prettier​

bool
default: False
backend: pants.backend.experimental.javascript.lint.prettier

If true, don't run Prettier on this target's code.

sources​

Iterable[str] | None
default: ('*.js', '*.cjs', '*.mjs', '!*.test.js', '!*.test.cjs', '!*.test.mjs')

A list of files and globs that belong to this target.

Paths are relative to the BUILD file's directory. You can ignore files/globs by prefixing them with !.

Example: sources=['utils.js', 'subdir/*.js', '!ignore_me.js']

tags​

Iterable[str] | None
default: None

Arbitrary strings to describe a target.

For example, you may tag some test targets with 'integration_test' so that you could run pants --tag='integration_test' test :: to only run on targets with that tag.
