Package Exports

npm-package-json-lint

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (npm-package-json-lint) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

npm-package-json-lint

A package.json linter for Node projects

What is npm-package-json-lint?

npm-package-json-lint helps enforce standards for your package.json file. Currently it can check for:

validity of data types in nodes. Ex: name should always be a string.
whether a string is a lowercase
whether a version number is a valid
the presence of a given module
the presence of a pre-release version of a module
and much more!

Please see the wiki for a list of rules.

Examples

Run a specific rule, require-author, on a file relative to the current working directory. pjl-cli -f "../relative-path/package.json" -r "require-author"

Run a specific rule, require-author, ignoring warnings on a file relative to the current working directory. pjl-cli -f "../relative-path/package.json" -r "require-author" --ignore-warnings

Run a specific rule, require-author, set severity to warning on a file relative to the current working directory. pjl-cli -f "../relative-path/package.json" -r "require-author" -s "warning"

Run using the config in .npmpackagejsonlintrc on a file relative to the current working directory. pjl-cli -f "../relative-path/package.json" -c "./.npmpackagejsonlintrc"

Run using the default config on a file relative to the current working directory pjl-cli -f "../relative-path/package.json"

Lint Rules

npm-package-json-lint has a configurable set of rules. Please see the wiki for a full list of available rules. By default no rules are enabled. If you would like to use npm-package-json-lint's default ruleset, please see npm-package-json-lint-config-default.

Each rule contains the following properties:

ID - example: require-author
Node - example: author
Message - example: author is required
Rule Type - example: required

As mentioned in the "Commands and configuration" section there are two ways to specify rule sets. The first is using --rule to specify a given rule. This will run npm-package-json-lint with just this rule. The second is using --rules-file to specify a JSON file, named .npmpackagejsonlintrc, to run a set of rules. If neither of the options above are specified then npm-package-json-lint looks for a global .npmpackagejsonlintrc file in the root of your user directory.

Configuring rules

npm-package-json-lint rules can either be run as an error, warning, or off.

"warning" - run the rule as a warning
"error" - run the rule as an error
"off" - disables the rule

Ex: "require-author": "error"
