HTTP Server Library

The HTTP server library helps to quickly create a consistent HTTP server with some useful middlewares, OpenAPI, Prometheus metrics and standard access controls.

The server is focused on serving REST style APIs and is based on the Gorilla Mux request router and dispatcher.

Getting started

Add the module to your project:

$  go get southwinds.dev/http

Set up the server:

package main

import (
    "github.com/gorilla/mux"
    "net/http"
    h "southwinds.dev/http"
)

func main() {
    // create a new server
    server := h.New("test")
    // configure http handlers
    server.Http = func(router *mux.Router) {
        // add basic authentication
        router.Use(server.AuthenticationMiddleware)
        // add handler
        router.HandleFunc("/", doSomething).Methods("GET")
    }
    server.Serve()
}

func doSomething(writer http.ResponseWriter, request *http.Request) {
    writer.WriteHeader(http.StatusOK)
}

For a more complete example see here.

HTTP_OPEN_API_ENABLED	enables Swagger enpoint at /api/	true
