package_json

A package.json file describing a nodejs package. (https://nodejs.org/api/packages.html#introduction)

Generates a node_package target for the package.

Generates node_third_party_package targets for each specified 3rd party dependency (e.g. in the package.json#devDependencies 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/2.21/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.

scripts​

Iterable[Any] | None
default: ()

Custom node package manager scripts that should be known and ran as part of relevant goals.

Maps the package.json#scripts section to a cacheable pants invocation.

source​

str | None
default: 'package.json'

A single file that belongs to this target.

Path is relative to the BUILD file's directory, e.g. source='example.ext'.

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.
