description Fiber Overview

Fiber is a Go web framework designed for building fast and efficient backend applications. It leverages Go’s concurrency features—goroutines—to handle numerous simultaneous requests effectively. Its architecture utilizes middleware pipelines to streamline request processing. Fiber is suitable for developers creating APIs and other network services who prioritize performance and maintainability within the Go ecosystem.

help Fiber FAQ

Is Fiber compatible with Go's standard net/http handlers and middleware?

Not automatically. Fiber is built on fasthttp rather than net/http, so middleware and handlers written specifically for the standard library may need an adapter or a Fiber-native replacement.

Why does Fiber's API look familiar to Express developers?

Fiber deliberately uses an Express-inspired routing and middleware style, including methods such as Get, Post, and Use. That makes its structure approachable for developers moving from Node.js, although the code still follows Go's type system and compilation model.

How do route parameters and middleware work in Fiber?

Routes can include named parameters such as /users/:id, which handlers read from Fiber's context. Middleware is registered with app.Use or attached to specific route groups, allowing authentication, logging, and request processing to run in sequence.

When is Gin a safer choice than Fiber for a Go API?

Gin is based on net/http and therefore fits more directly into Go's standard HTTP ecosystem. Fiber may appeal when its Express-like API and fasthttp foundation are priorities, but compatibility requirements should be checked before reusing standard-library middleware.
