Alien 
Alien is a lightweight http router( multiplexer) for Go( Golang ), made for humans who don't like magic.
Documentation docs
Features
- fast ( see the benchmarks, or run them yourself)
- lightweight ( just a single file read all of it in less than a minute)
- safe( designed with concurrency in mind)
- middleware support.
- routes groups
- no external dependency( only the standard library )
Motivation
I wanted a simple, fast, and lightweight router that has no unnecessary overhead using the standard library only, following good practices and well tested code( Over 90% coverage)
Installation
go get github.com/gernest/alien
Usage
normal static routes
package main
import (
"log"
"net/http"
"github.com/gernest/alien"
)
func main() {
m := alien.New()
m.Get("/", func(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("hello world"))
})
log.Fatal(http.ListenAndServe(":8090", m))
}
visiting your localhost at path / will print hello world
named params
package main
import (
"log"
"net/http"
"github.com/gernest/alien"
)
func main() {
m := alien.New()
m.Get("/hello/:name", func(w http.ResponseWriter, r *http.Request) {
p := alien.GetParams(r)
w.Write([]byte(p.Get("name")))
})
log.Fatal(http.ListenAndServe(":8090", m))
}
visiting your localhost at path /hello/tanzania will print tanzania
catch all params
package main
import (
"log"
"net/http"
"github.com/gernest/alien"
)
func main() {
m := alien.New()
m.Get("/hello/*name", func(w http.ResponseWriter, r *http.Request) {
p := alien.GetParams(r)
w.Write([]byte(p.Get("name")))
})
log.Fatal(http.ListenAndServe(":8090", m))
}
visiting your localhost at path /hello/my/margicl/sheeplike/ship will print my/margical/sheeplike/ship
middlewares
Middlewares are anything that satisfy the interface func(http.Handler)http.Handler . Meaning you have thousands of middlewares at your disposal, you can use middlewares from many golang http frameworks on alien(most support the interface).
package main
import (
"log"
"net/http"
"github.com/gernest/alien"
)
func middleware(h http.Handler) http.Handler {
return http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("hello middlware"))
})
}
func main() {
m := alien.New()
m.Use(middleware)
m.Get("/", func(_ http.ResponseWriter, _ *http.Request) {
})
log.Fatal(http.ListenAndServe(":8090", m))
}
visiting your localhost at path / will print hello middleware
groups
You can group routes
package main
import (
"log"
"net/http"
"github.com/gernest/alien"
)
func main() {
m := alien.New()
g := m.Group("/home")
m.Use(middleware)
g.Get("/alone", func(w http.ResponseWriter, _ *http.Request) {
w.Write([]byte("home alone"))
})
log.Fatal(http.ListenAndServe(":8090", m))
}
visiting your localhost at path /home/alone will print home alone
