Question 1

How to handle file uploads with httpin in Go?

Accepted Answer

Define a struct field with the `in:"form=file"` directive for multipart form data, and httpin will bind uploaded files to Go types like multipart.FileHeader, as mentioned in the Core Features for file uploads. Check the documentation for specific examples on handling file metadata and storage.

Question 2

httpin vs gorilla/schema: which is better for form data?

Accepted Answer

httpin is more comprehensive, handling multiple input sources like JSON and headers, while gorilla/schema is focused only on form values. Choose httpin for full HTTP request binding or gorilla/schema if you need a lightweight, form-specific solution with fewer dependencies.

Question 3

Can I use httpin with Gin framework for JSON binding?

Accepted Answer

Yes, httpin openly integrates with Gin via middleware, allowing you to decode JSON bodies and other inputs into structs. The documentation provides integration examples, but note that Gin has its own binding features, so evaluate if httpin adds value for your use case.

Question 4

How to add custom validation in httpin?

Accepted Answer

Implement custom directives or use post-processing hooks after httpin decodes the struct. The extensibility section mentions custom directives, but for complex validation, you might need to combine httpin with libraries like go-playground/validator or write manual checks.

Question 5

httpin performance impact on high traffic servers?

Accepted Answer

There's some reflection overhead, so for extremely high-throughput APIs, benchmark against hand-written parsing. However, for most applications, the productivity gains outweigh minor performance costs, and caching decoded structs can help mitigate issues.

Question 6

How to decode nested structs with httpin?

Accepted Answer

Use struct tags on nested fields, similar to top-level ones, and httpin will recursively decode data. The documentation likely covers this, but ensure your input sources (e.g., JSON keys) map correctly to the nested struct hierarchy to avoid binding errors.
