Package gateway provides a drop-in replacement for net/http's `ListenAndServe` for use in AWS Lambda & API Gateway, simply swap it out for `gateway.ListenAndServe`. Extracted from [Up](https://github.com/apex/up) which provides additional middleware features and operational functionality.
```go
package main
import (
"fmt"
"log"
"net/http"
"os"
"github.com/apex/gateway"
)
func main() {
addr := ":" + os.Getenv("PORT")
http.HandleFunc("/", hello)
log.Fatal(gateway.ListenAndServe(addr, nil))
}
func hello(w http.ResponseWriter, r *http.Request) {
fmt.Fprintln(w, "Hello World from Go")
}
```
