MetaMask's Node.js ESLint configuration.

Usage

yarn add --dev \

    @metamask/eslint-config-nodejs@^14.0.0 \
    eslint@^9.11.0 \
    eslint-config-prettier@^9.1.0 \
    eslint-plugin-import-x@^4.3.0 \
    eslint-plugin-jsdoc@^50.2.4 \

    prettier@^3.3.3

The order in which you extend ESLint rules matters. The @metamask/* eslint configs should be added to the config array last, with @metamask/eslint-config first, and @metamask/eslint-config-* in any order thereafter.

import base, { createConfig } from '@metamask/eslint-config';
import nodejs from '@metamask/eslint-config-nodejs';

const config = createConfig({
  {
    extends: [
      // Any custom shared config should be added here.
      // ...

      // This should be added last unless you know what you're doing.
      base,
      nodejs,
    ],
  }
});

To lint the .eslintrc.js file itself, you will need to add this config in addition to the base config.
