lambda-http-adaptor

lambda-http-adaptor is a compatible adaptor for Go net/http that can be used in multiple serverless environments.

You can run your existing http.HandlerFunc compatible web application on AWS Lambda or Azure Functions.

Example

lambda-http-adaptor provides the adaptor.ListenAndServe method, which can drop-in replacement for the http.ListenAndServe.

package main

import (
	"github.com/yacchi/lambda-http-adaptor"
	_ "github.com/yacchi/lambda-http-adaptor/all"
	"log"
	"net/http"
)

func main() {
	log.Fatalln(adaptor.ListenAndServe("", http.HandlerFunc(echoReplyHandler)))
}

func echoReplyHandler(w http.ResponseWriter, r *http.Request) {
	m := r.URL.Query().Get("message")
	w.Header().Set("Content-Type", "text/plain")
	w.Write([]byte(m))
}

Pass through non-http events

Pass-through of non-HTTP Events has been added in v0.5.0. The destination path is /events by default. If you want to change the forwarding path or stop forwarding, please refer to the following sample for configuration.

func main() {
  log.Fatalln(adaptor.ListenAndServeWithOptions(
    "",
    handler,
    // aws.WithNonHTTPEventPath("/api"),
	// aws.WithoutNonHTTPEventPassThrough(),
  )
}
