First of all we need to install ngrok
You can expose anything like a simple website, tcp client server chat etc.................
I'll expose a simple html page.
We are gonna use python3 to start a server locally.

Here we can see our web page is running locally.

Keep the local server on.
open up another terminal on the same directory location.
Now we have to set authentication token for ngrok.
go to here register an acoount. go to Your Authtoken
and you get your auth token....
To set auth token.
in the terminal type
ngrok config add-authtoken your-auth-token
Now you are ready to use ngrok..
in the terminal typengrok http port no. in my case it's 9191
ngrok http 9191

Visit the web interface address.

Now you can visit the Forwarding address to access the web page from anywhere in the world.............
