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.
go get -u -v github.com/talentlessguy/golang-reload-browserOpen a browser and press "Enter" in console.
Go code:
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:

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}`)
