Localtunnel 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.
Localtunnel command line script allows you to manually setup a sharing tunnel to a local webserver.
npm install -g localtunnel
Start a webserver on some local port (in our example we have a server running on port 8000).
Make sure everything is working locally first by visiting http://localhost:8000.
Now use the command line app to request a tunnel to your local server.
$ lt --port 8000 your url is: https://gqgh.localtunnel.me
You can now share https://gqgh.localtunnel.me with anyone. As long as your local instance of lt is running, this url will remain active. Any requests to that url will be routed to your service on port 8000.
When you start and stop your tunnel, you will see it reflected in the active tunnel count below.
