Installation
This package requires ESLint 8 and jsonc-eslint-parser
:
npm install eslint eslint-plugin-package-json jsonc-eslint-parser --save-dev
Usage
Flat Config
This plugin's recommended configuration enables its rules on **/package.json
files, parsing them with jsonc-eslint-parser
:
In your ESLint configuration file:
import packageJson from "eslint-plugin-package-json/configs/recommended";
export default [
// your other ESLint configurations
packageJson,
];
If you want to override the recommended rules:
import packageJson from "eslint-plugin-package-json/configs/recommended";
export default [
// your other ESLint configurations
{
...packageJson,
rules: {
...packageJson.rules,
"package-json/valid-package-def": "off",
},
},
];
See ESLint's Configuration Files guide for details on how to customize your rules and other config settings.
Legacy Config
Add an override to your ESLint configuration file that specifies this plugin, jsonc-eslint-parser
, and its recommended rules for your package.json
file:
module.exports = {
overrides: [
{
extends: ["plugin:package-json/recommended"],
files: ["package.json"],
parser: "jsonc-eslint-parser",
plugins: ["package-json"],
},
],
};
You may also want to individually configure rules. See ESLint's Configure Rules guide for details on how to customize your rules.
module.exports = {
overrides: [
{
extends: ["plugin:package-json/recommended"],
files: ["package.json"],
parser: "jsonc-eslint-parser",
plugins: ["package-json"],
rules: {
"package-json/valid-package-def": "error",
},
},
],
};
Usage Alongside Prettier
prettier-plugin-packagejson
is a Prettier plugin that enforces the same package.json
keys ordering as the order-properties
and sort-collections rules with default options.
We recommend using both the Prettier plugin and eslint-plugin-package-json
's recommended configuration.
The default settings don't conflict, and Prettier plugins can quickly fix up ordering in your editor on save and/or as a Git hook.

| Name | Description | 💼 | 🔧 | 💡 | | :--------------------------------------------------------------------- | :---------------------------------------------------------------------------------------------- | :- | :- | :- | | order-properties | Package properties must be declared in standard order | ✅ | 🔧 | | | repository-shorthand | Enforce either object or shorthand declaration for repository. | ✅ | 🔧 | | | sort-collections | Dependencies, scripts, and configuration values must be declared in alphabetical order. | ✅ | 🔧 | | | unique-dependencies | Enforce that if repository directory is specified, it matches the path to the package.json file | ✅ | | 💡 | | valid-local-dependency | Checks existence of local dependencies in the package.json | ✅ | | | | valid-name | Enforce that package names are valid npm package names | ✅ | | | | valid-package-def | Enforce that package.json has all properties required by the npm spec | ✅ | | | | valid-repository-directory | Enforce that if repository directory is specified, it matches the path to the package.json file | ✅ | | 💡 | | valid-version | Enforce that package versions are valid semver specifiers | ✅ | | |
These rules only run on package.json
files; they will ignore all other files being linted.
They can lint package.json
files at project root and in any subfolder of the project, making this plugin great for monorepos.
