Project Setup​

1. Basic Project Structure​

project/
  ├── src/
  │   ├── index.js
  │   └── components/
  ├── tests/
  ├── package.json
  ├── .gitignore
  ├── .eslintrc
  └── README.md

2. Configuration Files​

  • package.json: Project metadata and dependencies
  • .gitignore: Git ignore patterns
  • .eslintrc: ESLint configuration
  • .prettierrc: Prettier configuration

3. npm Scripts​

{
  "scripts": {
    "start": "node src/index.js",
    "dev": "nodemon src/index.js",
    "test": "jest",
    "lint": "eslint src",
    "format": "prettier --write src"
  }
}

Best Practices​

1. Development Workflow​

  • Use version control from start
  • Implement continuous integration
  • Regular code reviews
  • Automated testing

2. Environment Management​

  • Use .env files for environment variables
  • Separate development and production configs
  • Use cross-env for cross-platform compatibility

3. Security Practices​

  • Keep dependencies updated
  • Use npm audit regularly
  • Implement security linting
  • Follow security best practices
