Question 1

How to handle authentication with go-rest?

Accepted Answer

go-rest does not have built-in authentication; you'll need to implement it manually in your handlers, such as by checking headers or tokens before processing requests, which adds complexity compared to frameworks with integrated auth.

Question 2

Does go-rest support middleware?

Accepted Answer

No, go-rest lacks built-in middleware support. For middleware-like functionality, you must wrap handler functions or handle logic within the handlers themselves, limiting extensibility for cross-cutting concerns.

Question 3

How to add query parameters to a GET request in go-rest?

Accepted Answer

Use the url.Values parameter in your handler function, as shown in the README example, to access query parameters passed in the URL, making it straightforward for simple use cases.

Question 4

Is go-rest suitable for production use?

Accepted Answer

While fine for prototyping or small internal tools, its non-idiomatic use of reflection and limited features may pose risks for production applications requiring robustness, performance, and scalability in line with Go best practices.

Question 5

go-rest vs Gin: which is better for simple APIs?

Accepted Answer

go-rest is more minimal and easier for quick setups with automatic JSON handling, but Gin offers more features, better performance, and is more idiomatic for Go, making it a safer choice for most real-world projects.

Question 6

How to handle errors in go-rest?

Accepted Answer

Return an error as the second value from your handler function; if not nil, it will be displayed as a 500 internal server error, as explained in the README, providing basic but manual error management.
