lhttp: a Go Lambda Proxy
With lhttp you can deploy idiomatic Go HTTP server code as an AWS Lambda function using AWS Api Gateway.
For example, this is a basic Go server from the http package Godoc:
http.Handle("/foo", fooHandler)
http.HandleFunc("/bar", func(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path))
})
log.Fatal(http.ListenAndServe(":8080", nil))
This is the equivalent implementation using lhttp:
lhttp.Handle("/foo", fooHandler)
lhttp.HandleFunc("/bar", func(w http.ResponseWriter, r *http.Request) {
fmt.Fprintf(w, "Hello, %q", html.EscapeString(r.URL.Path))
})
log.Fatal(lhttp.ListenAndServe("", nil))
See the examples for more details.

Variables ¶
var DefaultServeMux = &defaultServeMux
DefaultServeMux is the default ServeMux used by Serve.
var LambdaContextKey = contextKey{"lambda-context"}
LambdaContextKey is a context key. It can be used by handlers to access the AWS Lambda Context from the Request object. The associated value will be of type LambdaContext
var LambdaRequestContextKey = contextKey{"lambda-request-context"}
LambdaRequestContextKey is a context key. It can be used by handlers to access the AWS Lambda Request Context from the Request object.
Functions ¶
func Handle ¶
Handle registers the handler for the given pattern in the DefaultServeMux. The documentation for http.ServeMux explains how patterns are matched.
func HandleFunc ¶
func HandleFunc(pattern string, handler func(http.ResponseWriter, *http.Request))
HandleFunc registers the handler function for the given pattern in the DefaultServeMux. The documentation for http.ServeMux explains how patterns are matched.
