When we develop some apps which integrate with third-party services, we need to make our local development server to be exposed to the Internet. To do that, we need an HTTP tunnel for our local server. How does the HTTP tunnel work? In this article, I will show you how I build an HTTP tunnel tool.

Why Do We Need To Deploy Our Own HTTP Tunnel Service?

There are lots of awesome online services for HTTP tunnels. For example, we can use ngrok to get paid fixed public domain to connect your local server. It also has a free package. But for the free package, you can’t get a fixed domain. Once you restart the client, you will get a new random domain. It is inconvenient when you need to save the domain in a third-party service.
