Tunnel

Public URLs for exposing your local web server using ngrok's API.

Installation

The only requirement is the Go Programming Language.

$ go get github.com/kataras/tunnel@latest

Getting Started

First of all, navigate to https://ngrok.com/, create an account and download ngrok. Extract the downloaded zip file anywhere you like and optionally add it to your PATH or NGROK system environment variable. Test if installation successfully completed by running the following command:

$ ngrok version

Import the package:

package main

import "github.com/kataras/tunnel"

Start a new local http Server and expose it to the internet using just a single new line of code:

func main() {
    // [...http.HandleFunc]

    srv := &http.Server{Addr: ":8080"}
    // 1 LOC:
    go fmt.Printf("• Public Address: %s\n", tunnel.MustStart(tunnel.WithServers(srv)))
    //
    srv.ListenAndServe()
}

OR

config := tunnel.Configuration{
    // AuthToken: "<YOUR_AUTHTOKEN>",
    // Bin: "C:/ngrok.exe",
    // WebInterface: "http://127.0.0.1:4040",
    // Region: "eu",
    Tunnels: []tunnel.Tunnel{
        {Name: "my-app", Addr: ":8080"},
    },
}
publicAddrs := tunnel.MustStart(config)
fmt.Printf("• Public Address: %s\n", publicAddrs)

Example output:

• Public Address: https://ef02b1377b65.ngrok.io
