Automated Code Review Setup

Automate code quality enforcement with linters, formatters, pre-commit hooks, and CI checks. Catch issues before human review so reviewers can focus on logic and design.

When to Use

• Setting up a new JavaScript/TypeScript project
• Adding linting or formatting to an existing project
• Configuring Git pre-commit hooks
• Setting up CI/CD quality gates
• Establishing CODEOWNERS for automatic reviewer assignment

Core Patterns

ESLint Configuration

Modern flat config for TypeScript projects.

// eslint.config.js
import eslint from '@eslint/js';
import tseslint from 'typescript-eslint';
import eslintPluginImport from 'eslint-plugin-import';

export default tseslint.config(
  eslint.configs.recommended,
  ...tseslint.configs.recommended,
  {
    rules: {
      // Prevent common bugs
      'no-console': 'warn',
      'no-debugger': 'error',
      'no-unused-vars': 'off',
      '@typescript-eslint/no-unused-vars': ['error', {
        argsIgnorePattern: '^_',
        varsIgnorePattern: '^_',
      }],

      // Enforce code quality
      '@typescript-eslint/explicit-function-return-type': 'off',
      '@typescript-eslint/no-explicit-any': 'warn',
      '@typescript-eslint/no-non-null-assertion': 'warn',

      // Import organization
      'import/order': ['error', {
        groups: ['builtin', 'external', 'internal', 'parent', 'sibling'],
        'newlines-between': 'always',
        alphabetize: { order: 'asc' },
      }],
    },
  },
  {
    ignores: ['dist/', 'node_modules/', 'coverage/'],
  }
);

Prettier Configuration

Set up Prettier for consistent formatting.

// .prettierrc
{
  "semi": true,
  "singleQuote": true,
  "trailingComma": "all",
  "printWidth": 100,
  "tabWidth": 2,
  "arrowParens": "avoid",
  "endOfLine": "lf"
}

// .prettierignore
dist
node_modules
coverage
pnpm-lock.yaml
package-lock.json

// package.json scripts
{
  "scripts": {
    "lint": "eslint .",
    "lint:fix": "eslint . --fix",
    "format": "prettier --write .",
    "format:check": "prettier --check ."
  }
}
