Instadrop - signal server backend

---

This is a signal server backend template for Instadrop. You can deploy this on:

• your server with a public IP (enabling cross-subnet file transfer/file trasfer when not connected to same WIFI network)
• your home computer(enabling LAN file transfer only)

---

About

This server backend is powered by Express.js + socket.io, with a core duty of signaling for WebRTC service.

Customizing

You can change the listening port by editing the startup variable when starting up the server. For example:
(bash)

PORT=8080 node server.js

(Powershell)

$env:PORT=8080; node server.js

If successful, you should see messages like this:

====================================
Instadrop Signaling Server Running
Port: 8080
====================================

Tip

The default listening port is 3000.
If you start up without a variable, the program will automatically set 3000 as its listening port.

---

Finalizing

Please open up your InstaDrop client, go to Settings -> Advanced network settings and set the Signal server value to your own server. For example:

http://your.server-url.com:3000

Tip

We recommend you to set up a SSL for your own signaling server for advanced security if you have a public server.
Please take a look at Certbot(for Linux) or win-acme(for Windows) for further SSL configuration information.
After setting up a SSL, you can configure it by setting up nginx.
