Tested on linux, hopefully supports Mac, Windows, and Linux

Installation

Download ngrok binary file

Install package

go get github.com/afdalwahyu/gonnel

Update

go get -u github.com/afdalwahyu/gonnel

Examples:

Create client & tunnel

package main

import (
    "fmt"
    "github.com/afdalwahyu/gonnel"
    "bufio"
    "os"
)

func main() {
    client, err := gonnel.NewClient(gonnel.Options{
        BinaryPath: "../ngrok-bin/ngrok_linux",
    })
    if err != nil {
        fmt.Println(err)
    }
    defer client.Close()

    done := make(chan bool)
    go client.StartServer(done)
    <-done

    client.AddTunnel(&gonnel.Tunnel{
        Proto:        gonnel.HTTP,
        Name:         "awesome",
        LocalAddress: "127.0.0.1:4040",
        Auth:         "username:password",
    })

    client.ConnectAll()

    fmt.Print("Press any to disconnect")
    reader := bufio.NewReader(os.Stdin)
    reader.ReadRune()

    client.DisconnectAll()
}

How it works

Inspired from node.js wrapper that use ngrok binary, run it and use client api to create or close tunnel
