Build me a web framework in Go. I want it to be heavily inspired by Express.js from the Node world, so the API should feel really familiar and easy to pick up, especially for developers who are new to Go.

The main focus should be on performance—it needs to be extremely fast with very low memory usage, so you should build it on top of Fasthttp instead of Go's standard library. It should have all the core features you'd expect, like robust routing, middleware support, and the ability to serve static files. Also, make sure it has built-in support for things like WebSockets, template engines, and a rate limiter. The goal is to make server-side development in Go fast, flexible, and friendly.
