eslint-plugin-no-use-extend-native

ESLint plugin to prevent use of extended native objects

Install

First, install ESLint via

npm install --save-dev eslint

Then install eslint-plugin-no-use-extend-native

npm install --save-dev eslint-plugin-no-use-extend-native

Usage

In your eslint.config.js file add the plugin as such:

import eslintPluginNoUseExtendNative from 'eslint-plugin-no-use-extend-native'

export default [
  {
    plugins: {
      'no-use-extend-native': eslintPluginNoUseExtendNative,
    },
    rules: {
      'no-use-extend-native/no-use-extend-native': 2,
    },
  },
]

If you want the default of the single rule being enabled as an error, you can also just use the following instead of all of the above:

import eslintPluginNoUseExtendNative from 'eslint-plugin-no-use-extend-native'

export default [
  eslintPluginNoUseExtendNative.configs.recommended,
]

With this plugin enabled, ESLint will find issues with using extended native objects:

import colors from 'colors';
console.log('unicorn'.green);
// => ESLint will give an error stating 'Avoid using extended native objects'

[].customFunction();
// => ESLint will give an error stating 'Avoid using extended native objects'

More examples can be seen in the tests.

Usage with no-extend-native

ESLint’s no-extend-native rule verifies code is not modifying a native prototype. e.g., with the no-extend-native rule enabled, the following lines are each considered incorrect:

String.prototype.shortHash = function() { return this.substring(0, 7); };
Object.defineProperty(Array.prototype, "times", { value: 999 });

no-use-extend-native verifies code is not using a non-native prototype. e.g., with the no-use-extend-native plugin enabled, the following line is considered incorrect:

"50bda47b09923e045759db8e8dd01a0bacd97370".shortHash() === "50bda47";

The no-use-extend-native plugin is designed to work with ESLint’s no-extend-native rule. no-extend-native ensures that native prototypes aren’t extended, and should a third party library extend them, no-use-extend-native ensures those changes aren’t depended upon.
