ApiTunnel

express-apitunnel

Expose local web services to remote express.js application

About

express-apitunnel allows to expose a web service running on a local device to an express.js api.

Here are some wonderful things you can do with it:

• Control devices in your local network from anywhere
• Perform large tasks on a local machine (downloading files for example)
• Hook your IP camera feed to an express route
• You can hook more than one worker to one express route and the server will automatically balance load among them.
• You can turn on your teapot while you still at the office...
• ...

Usage

Local Server -> Api Tunnel -> Public Server -> Browser/Clent

On a public server

  const socketio = require('socket.io');
  const express = require('express');
  const app = express()
  const io = socketio(server)
 
  // Require server plugin
  const { apitunnel_server } = require('express-apitunnel');
 
  apitunnel_server(app, io, {
 
    endpoint: 'home-devices',// if not specified api route will be at '/unit/:unitname/*url'
                             // the api route will be at '/home-devices/:unitname/*url'
    units:{
      raspberry: 'qweqwe' // unit_name: access_token
    }
  })
 
  // your application logic ...

On a local device

 
  const { apitunnel_client } = require('express-apitunnel');
 
  apitunnel_client({
    server: 'https://example.com', // your public server address
    unit: 'raspberry', // unit name
    token: 'very_secret', // access
 
    hostname: "torrent-downloader.local", // host to establish tunnel with
    pretend: "example.com", // assume a hostname in http header - Host: example.com
    port: 80,// port of the tunneled service
  })
  .then(data => {
      // connected
  })
  .catch(data => {
     // failed to connect
  })
