What are the best practices for building web apps in Go?

When building web apps in Go, consider using the following best practices: 1. Use the net/http package for handling requests. 2. Implement middleware for logging and error handling. 3. Structure your project with a clear separation of concerns. 4. Use context for managing request-scoped values. 5. Optimize performance with goroutines and channels.

Can you explain the importance of middleware?

Middleware is crucial as it allows you to add functionality to your web app, such as logging, authentication, and error handling, without cluttering your main application logic.

What about error handling?

Error handling in Go should be explicit. Always check for errors after operations and handle them gracefully, possibly using a centralized error handler to maintain clean code.

How can I optimize performance in my Go web app?

You can optimize performance by using goroutines for concurrent processing, minimizing memory allocations, and using efficient data structures. Profiling your application can also help identify bottlenecks.
