Best Practices for Building APIs with Node.js and Express

Node.js with Express is one of the most popular combinations for building robust APIs.

Best Practices:

• Use MVC Structure: Keep code organized.
• Implement Authentication: Use JWT or OAuth for security.
• Enable Validation: Prevent bad data with tools like express-validator or Zod.
• Rate Limiting: Avoid abuse with libraries like express-rate-limit.
• Error Handling Middleware: Keep your API stable during unexpected failures.

A well-structured API makes it easier to maintain, scale, and secure your web application.
