nodejs-infer

Options controlling which dependencies will be inferred for javascript targets.

Backend: pants.backend.experimental.javascript.lint.prettier

Config section: [nodejs-infer]

Basic options​

imports​

--[no-]nodejs-infer-imports
PANTS_NODEJS_INFER_IMPORTS
pants.toml
[nodejs-infer]
imports = <bool>
default: True

Infer a target's imported dependencies by parsing import statements from sources.

To ignore a false positive, you can either put // pants: no-infer-dep on the line of the import or put !{bad_address} in the dependencies field of your target.

package_json_entry_points​

--[no-]nodejs-infer-package-json-entry-points
PANTS_NODEJS_INFER_PACKAGE_JSON_ENTRY_POINTS
pants.toml
[nodejs-infer]
package_json_entry_points = <bool>
default: True

Infer a package_json's dependencies by parsing entry point statements from the package.json file.

To ignore a false positive, you can put !{bad_address} in the dependencies field of the package_json target.

See https://nodejs.org/api/packages.html#package-entry-points and https://docs.npmjs.com/cli/v9/configuring-npm/package-json#browser.

unowned_dependency_behavior​

--nodejs-infer-unowned-dependency-behavior=<UnownedDependencyUsage>
PANTS_NODEJS_INFER_UNOWNED_DEPENDENCY_BEHAVIOR
pants.toml
[nodejs-infer]
unowned_dependency_behavior = <UnownedDependencyUsage>
one of: error, warning, ignore
default: warning

How to handle imports that don't have an inferrable owner.

Usually when an import cannot be inferred, it represents an issue like Pants not being properly configured, e.g. targets not set up. Often, missing dependencies will result in confusing runtime errors like Error: ENOENT: no such file or directory, so this option can be helpful to error more eagerly.

To ignore any false positives, add // pants: no-infer-dep to the line of the import
