# Golang page reloader

__I forked the repository to add go module and custom port.__

This is a small sample application implemented in Golang which can programmatically refresh a tab in a browser.

It is accompanying a blog post I've written about the subject with all the details: .

It hosts a small WebSocket service with a single `reload` endpoint, to which we can connect from the browser, and send a message every time we want it to be reloaded.

## Install

```sh

go get -u -v github.com/talentlessguy/golang-reload-browser

```

Open a browser and press "Enter" in console.

## Example

Go code:

```go

package main

import (

	"bufio"

	"log"

	"os"

	rl "talentlessguy/golang-reload-browser"

)

func main() {

	log.Println("Starting reload server.")

	rl.StartReloadServer(":3000")

	log.Println("Reload server started.")

	log.Println("Press Enter to reload the browser!")

	for {

		reader := bufio.NewReader(os.Stdin)

		reader.ReadString('\n')

		log.Println("Reloading browser.")

		rl.SendReload()

	}

}

```

HTML page:

```html

  

    Reload test page

    

      const tryConnectToReload = address => {

        const conn = new WebSocket(address)

        conn.onclose = () => {

          setTimeout(() => {

            tryConnectToReload(address)

          }, 2000)

        }

        conn.onmessage = evt => location.reload()

      }

      try {

        if (window.WebSocket) {

          // The reload endpoint is hosted on a statically defined port.

          tryConnectToReload('ws://localhost:3000/reload')

        } else {

          console.log( 'Your browser does not support WebSockets :(')

        }

      } catch (e) {

        console.error(`Exception during connecting to Reload: ${e}`)

      }

    

  

```

Then run go file:

```sh

go run main.go

```
