Intro

Goal: Use community rule sets like airbnb, standard, and google for consistent style without manual tuning.

Airbnb config

Airbnb is a popular strict style, especially for React. It enforces semicolons, spacing, and React best practices.

npm install --save-dev eslint-config-airbnb-typescript eslint-plugin-import eslint-plugin-jsx-a11y eslint-plugin-react eslint-plugin-react-hooks

Standard config

Standard is simpler: no semicolons, minimal config, widely used in Node projects.

npm install --save-dev eslint-config-standard eslint-plugin-import eslint-plugin-n eslint-plugin-promise

Google config

Google config focuses on readability and clarity, used in large codebases.

npm install --save-dev eslint-config-google

Combine configs

You can extend multiple configs: Airbnb + Prettier + TS rules. Ensure parserOptions.project is set for type-aware rules.

// .eslintrc.js example
module.exports = {
  extends: [
    "airbnb-typescript/base",
    "plugin:prettier/recommended"
  ],
  parserOptions: {
    project: "./tsconfig.json"
  }
}

Team alignment

Pick one rule set per project to avoid endless style debates. Align team on it, then focus energy on features.
