What is eslint-plugin-eslint-plugin?

eslint-plugin-eslint-plugin is an ESLint plugin designed to help developers create and maintain their own ESLint plugins. It provides rules and utilities that enforce best practices and catch common mistakes in ESLint plugin development.

What are eslint-plugin-eslint-plugin's main functionalities?

Rule to enforce meta property in rule definitions

This feature ensures that each rule in your ESLint plugin has a `meta.docs.url` property, which is useful for documentation purposes.

module.exports = {
  rules: {
    'require-meta-docs-url': require('./lib/rules/require-meta-docs-url')
  }
};

Rule to enforce correct rule tester usage

This feature checks that your rule tests are consistent and follow best practices, ensuring that your tests are reliable and maintainable.

module.exports = {
  rules: {
    'consistent-output': require('./lib/rules/consistent-output')
  }
};

Rule to enforce correct use of context.report

This feature ensures that you are using the `context.report` API correctly, avoiding deprecated methods and promoting the use of the latest API.

module.exports = {
  rules: {
    'no-deprecated-report-api': require('./lib/rules/no-deprecated-report-api')
  }
};

Other packages similar to eslint-plugin-eslint-plugin

eslint-plugin-eslint-comments

eslint-plugin-eslint-comments provides rules for best practices around ESLint directive comments (e.g., `// eslint-disable`). It helps ensure that these comments are used correctly and not overused, which is somewhat related to maintaining ESLint configurations but focuses on comments rather than plugin development.

eslint-plugin-node

eslint-plugin-node provides rules for Node.js-specific code, ensuring that your code adheres to best practices for Node.js development. While it is not focused on ESLint plugin development, it shares the goal of improving code quality through custom rules.

eslint-plugin-import

eslint-plugin-import offers rules to ensure proper import/export syntax and practices in JavaScript modules. It helps catch common issues with ES6 imports/exports, which is different from plugin development but similarly aims to improve code quality through linting.

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Add eslint-plugin to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{

}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "eslint-plugin/no-deprecated-report-api": "error"
    }
