@metamask/eslint-config-browser

@metamask/eslint-config-browser

MetaMask's ESLint configuration for browser environments.

Usage

Our default export contains a base set of ESLint rules for ES6+:

yarn add --dev \
    @metamask/eslint-config@^11.0.0 \
    @metamask/eslint-config-browser@^11.0.0 \
    eslint@^8.27.0 \
    eslint-config-prettier@^8.5.0 \
    eslint-plugin-import@^2.26.0 \
    eslint-plugin-jsdoc@^39.6.2 \
    eslint-plugin-prettier@^4.2.1 \
    prettier@^2.7.1

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

module.exports = {
  root: true,

  extends: [
    // These should be added last unless you know what you're doing.
    '@metamask/eslint-config',
    '@metamask/eslint-config-browser',
  ],
};
