eslint-plugin-perfectionist

What is eslint-plugin-perfectionist?

eslint-plugin-perfectionist is an ESLint plugin designed to enforce consistent code style and formatting rules. It helps developers maintain a clean and organized codebase by providing rules for sorting and organizing various code elements such as imports, properties, and more.

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

Sort Imports

This rule enforces a specific order for import statements. In this example, the order is set to 'builtin', 'external', and 'internal' imports.

module.exports = {
  "rules": {
    "perfectionist/sort-imports": ["error", {
      "order": ["builtin", "external", "internal"]
    }]
  }
};

Sort Object Properties

This rule enforces sorting of object properties in ascending order. The 'caseSensitive' option ensures that the sorting is case-sensitive.

module.exports = {
  "rules": {
    "perfectionist/sort-keys": ["error", "asc", {
      "caseSensitive": true,
      "natural": false
    }]
  }
};

Sort Class Members

This rule enforces a specific order for class members. In this example, the order is set to 'field', 'constructor', and 'method'.

module.exports = {
  "rules": {
    "perfectionist/sort-class-members": ["error", {
      "order": ["field", "constructor", "method"]
    }]
  }
};
