Share a web service on your local development machine with Localtunnel

I was testing Jenkins and as it doesn’t support localhost addresses I found Localtunnel, which, and I qote,

allows you to easily share a web service on your local development machine without messing with DNS and firewall settings.

Localtunnel will assign you a unique publicly accessible url that will proxy all requests to your locally running webserver.

You can  install it via npm:

npm install -g localtunnel

Then, start your project on some local port (for example 1337), and make sure all works well locally. Now, request a tunnel to your local server:

lt --port 1337

And you should get an output like:

your url is: https://awesome.localtunnel.me

You can use this link now and any requests to that url will be routed to your service on port 1337.
