# Fiber basic api

This repo tests basic fiber api setup while learning go at the same time ;-).

Fiber documentation is [here](https://docs.gofiber.io/)

## Initialize Go module

```bash

# initialize new app/module

go mod init fiber-api

```

## Install fiber package

```bash

# install fiber package

go get github.com/gofiber/fiber/v2

```

## Run fiber using multiple threads

```go

func main() {

	// define max number of processes

	// by default prefork will spawn process on each processor core

	runtime.GOMAXPROCS(4)

	// create fiber app

	app := fiber.New(fiber.Config{

		// enable multiple processes to run

		Prefork: true,

	})

	// ROUTES

	app.Get("/", Home)

	app.Get("/data", getData)

	app.Post("/data", postData)

	// start api in separate thread

	go startApi(app)

	// Create channel to signify a signal being sent

	c := make(chan os.Signal, 1)

	// When an interrupt is sent, notify the channel

	signal.Notify(c, os.Interrupt)

	// This blocks the main thread until an interrupt is received

	_ = <-c

	// Log closing of app processes

	if fiber.IsChild() {

		fmt.Println("Gracefully shutting down child process...")

	} else {

		fmt.Println("Gracefully shutting down parent process...")

	}

	// SHUTDOWN

	_ = app.Shutdown()

}

func startApi(app *fiber.App) {

	// listen to 8080 port

	err := app.Listen(":8080")

	if err != nil {

		panic(err)

	}

}

```
