Creating a RESTful API with Golang

Creating a RESTful API with Golang


Golang from Google is what the cool kids are using nowadays. So to get in on the hype. Here's how to get started by building your own API.

Initializing Go

Create a directory for your shiny new Go project.

mkdir goProject
cd goProject

Much like node Go has a dependency tracker. To initialize it run

go mod init

Create a main.go file and add the following code:

package main

import (

type Event struct {
	Id          string `json:"id"`
	Name        string `json:"name"`
	Desc        string `json:"desc"`
	PhoneNumber string `json:"phoneNumber"`

var events = []Event{
	Event{Id: "111", Name: "birthday", Desc: "jimmy's birthday", PhoneNumber: "+61416918059"},
	Event{Id: "112", Name: "anniversary", Desc: "jimmy's anniversary", PhoneNumber: "+61416918059"},
	Event{Id: "113", Name: "xmas", Desc: "Xmas", PhoneNumber: "+61416918059"},
	Event{Id: "114", Name: "custom", Desc: "custom event", PhoneNumber: "+61416918059"},

func ping(w http.ResponseWriter, r *http.Request) {
	fmt.Fprintf(w, "Server is running!")

func getAllEvents(w http.ResponseWriter, r *http.Request) {
	fmt.Println("retrieving all events")

// TODO: Add APIS to send messages

func handleRequests() {
	http.HandleFunc("/", ping)
	http.HandleFunc("/getAllEvents", getAllEvents)
	log.Fatal(http.ListenAndServe(":8080", nil))

func main() {
	fmt.Println("Starting Go Server !")

Then simply use this command to run the app:

go run .

And voila, there you have it. Your own Golang server.
