Question 1

How to add authentication to a Micro service?

Accepted Answer

Micro has no built-in authentication; you must use Express-compatible middleware like passport.js or implement custom logic, adding complexity for secure endpoints.

Question 2

Micro vs Express: which is better for building APIs?

Accepted Answer

Micro is better for simple, lightweight APIs with zero config and async/await focus, while Express offers more features like routing and middleware for complex applications.

Question 3

How to handle file uploads in Micro?

Accepted Answer

File uploads aren't natively supported; use middleware like multer with Express compatibility or parse raw requests manually, which adds setup steps.

Question 4

Can Micro be deployed on serverless platforms like Vercel?

Accepted Answer

Yes, Micro's lightweight nature makes it ideal for serverless functions on Vercel, AWS Lambda, or similar, but you may need to adapt for environment-specific constraints.

Question 5

What error handling patterns work best with Micro?

Accepted Answer

Micro automatically handles errors with HTTP status codes, but for custom responses, throw errors in async handlers or use middleware for more control.

Question 6

Is Micro suitable for real-time applications with WebSockets?

Accepted Answer

No, Micro focuses on HTTP microservices and lacks built-in WebSocket support; you'd need additional libraries or a different framework for real-time features.
