eslint-plugin-universe

ESLint plugin with Expo-specific rules.

Installation

npm install --save-dev eslint-plugin-universe

Requires ESLint 9 or later.

Usage

Add the plugin to your ESLint flat config:

import universe from 'eslint-plugin-universe';

export default [
  {
    plugins: {
      universe,
    },
    rules: {
      'universe/require-error-name': 'warn',
    },
  },
];

Or use the recommended config:

import universe from 'eslint-plugin-universe';

export default [universe.configs.recommended];

Rules

require-error-name

Requires Error subclasses to set prototype.name to the class name. This ensures error names are preserved after minification and appear correctly in stack traces.

Valid

class MyError extends Error {
  static {
    this.prototype.name = 'MyError';
  }
}

Invalid

// Missing name assignment
class MyError extends Error {}

// Wrong name value
class MyError extends Error {
  static {
    this.prototype.name = 'WrongName';
  }
}

This rule is auto-fixable with --fix.
