Linting & Formatting

ESLint brings consistency and quality to TypeScript projects. You and I can use ESLint to enforce code style, catch bugs, and maintain uniform coding standards across our codebase. Think of it as a quality control system that keeps our TypeScript code clean and predictable.

Prettier and AirBnB style guide work together to create visually consistent codebases. You and I can set up automated formatting that removes whitespace disputes and makes code reviews easier. These tools ensure our code looks professional and follows industry best practices.

When you and I integrate ESLint, Prettier, and AirBnB style guide into our projects, we establish clear coding standards that scale well. Our teams spend less time arguing over code style and more time building great features. The result is a codebase that reads like a well-written book - consistent, readable, and professional.

ESLint and Prettier Configuration

You and I can use ESLint with @typescript-eslint/parser to catch type-related errors while Prettier ensures consistent code formatting. This combination prevents common mistakes and creates code that looks professional across the entire project.

// .eslintrc.cjs
module.exports = {
  parser: '@typescript-eslint/parser',
  parserOptions: {
    ecmaVersion: 2022,
    sourceType: 'module',
  },
  plugins: ['@typescript-eslint'],
  extends: [
    'plugin:@typescript-eslint/recommended',
    'airbnb-base',
    'plugin:prettier/recommended'
  ],
  rules: {
    'prettier/prettier': 'error',
    '@typescript-eslint/no-unused-vars': 'error'
  }
};

// .prettierrc
{
  "singleQuote": true,
  "trailingComma": "es5",
  "printWidth": 80,
  "tabWidth": 2
}
