algnhsa is an AWS Lambda Go net/http server adapter.
algnhsa enables running Go web applications on AWS Lambda/API Gateway without changing the existing HTTP handlers:
package main
import (
"fmt"
"net/http"
"strconv"
"github.com/akrylysov/algnhsa"
)
func indexHandler(w http.ResponseWriter, r *http.Request) {
w.Write([]byte("index"))
}
func addHandler(w http.ResponseWriter, r *http.Request) {
f, _ := strconv.Atoi(r.FormValue("first"))
s, _ := strconv.Atoi(r.FormValue("second"))
w.Header().Set("X-Hi", "foo")
fmt.Fprintf(w, "%d", f+s)
}
func main() {
http.HandleFunc("/", indexHandler)
http.HandleFunc("/add", addHandler)
algnhsa.ListenAndServe(http.DefaultServeMux, nil)
