Question 1

How do I handle JSON requests and responses in gocraft/web?

Accepted Answer

gocraft/web doesn't include built-in JSON binding. You'll need to write custom middleware to parse JSON requests and serialize responses, or use community extensions like the linked json-binding package.

Question 2

gocraft/web vs gorilla/mux: which is better for my project?

Accepted Answer

gocraft/web offers better performance with O(log(N)) routing and static typing via contexts, while gorilla/mux has a simpler API and broader ecosystem. Choose gocraft/web for type safety and scalability, gorilla/mux for ease of use.

Question 3

How to implement authentication middleware with sessions?

Accepted Answer

Create a custom middleware that reads session cookies, sets user data in the context struct, and calls next() only if authenticated. The README provides an example with UserRequired middleware for guidance.

Question 4

Does gocraft/web support middleware that runs after the handler?

Accepted Answer

Yes, by placing code after the next() call in middleware, you can execute logic during the unwind phase, such as logging response times or cleaning up resources.

Question 5

How to handle CORS in gocraft/web?

Accepted Answer

Implement custom middleware to set CORS headers, or use the built-in OPTIONS handler to automatically allow methods. The README shows an example OPTIONS handler for adding Access-Control-Allow-Origin headers.

Question 6

Can I use gocraft/web with Go modules and newer Go versions?

Accepted Answer

Yes, it's compatible with Go modules, but note that the library hasn't seen major updates recently, so check for community forks or ensure it works with your Go version for long-term support.
