What does HackerNews think of gin?
Gin is a HTTP web framework written in Go (Golang). It features a Martini-like API with much better performance -- up to 40 times faster. If you need smashing performance, get yourself some Gin.
There are some well-established web frameworks for Go (e.g. https://github.com/gin-gonic/gin), but they are controversial too, as most Go developers seem to prefer libraries (that your code calls) instead of frameworks (that call your code and impose their structure upon it). So I don't think just cramming a framework from a completely different language into Go will fly...
Go: https://github.com/gin-gonic/gin
Rust: https://rocket.rs/
Julia: https://genieframework.com/
Gin has 1000s of production users right now. Please evaluate carefully before choosing one or the other.
And then there are countless GitHub projects where the README.md file, which is usually first thing I read, that is super well documented and written for the noob (imo). The best example of that so far, especially for someone like me just getting started with the framework, is the gin Golang http framework: (https://github.com/gin-gonic/gin) -- that readme is full of useful examples.
