eslint-config

This package publishes 4 shared ESLint configurations:

1. @code-shaper/eslint-config: Default configuration pointing to @code-shaper/eslint-config-lenient
2. @code-shaper/eslint-config-lenient: A lenient configuration for code bases that don't follow very opinionated coding conventions
3. @code-shaper/eslint-config-strict: A strict configuration for code bases that follow very opinionated coding conventions
4. @code-shaper/eslint-config/strict-react: The strict configuration + additional rules for React.

Installation

npm install -D @code-shaper/eslint-config

Then modify your .eslintrc.js to extend one of the above configurations, e.g.

module.exports = {
  root: true,
  env: { node: true },
  extends: ['@code-shaper/eslint-config/strict-react'],
};

Add the following dependencies to your package.json:

{
  "dependencies": {
    "@typescript-eslint/eslint-plugin": "^8.*",
    "eslint": "^8.*",
    "eslint-config-prettier": "^9.*",
    "eslint-import-resolver-typescript": "^3.*",
    "eslint-plugin-eslint-comments": "^3.*",
    "eslint-plugin-import": "^2.*",
    "eslint-plugin-jest": "^28.*",
    "eslint-plugin-jest-dom": "^5.*",
    "eslint-plugin-jsx-a11y": "^6.*",
    "eslint-plugin-only-error": "^1.*",
    "eslint-plugin-promise": "^7.*",
    "eslint-plugin-react": "^7.*",
    "eslint-plugin-react-hooks": "^4.*",
    "eslint-plugin-regexp": "^2.*",
    "eslint-plugin-tailwindcss": "^3.*",
    "eslint-plugin-testing-library": "^6.*"
  }
}

Note: If you are using eslint-config-next version 14, you may have to downgrade @typescript-eslint/eslint-plugin to version 7. eslint-config-next does not support @typescript-eslint/eslint-plugin version 8 yet.
