You can generate a PDF of your local application using a Secure tunnel to localhost with Ngrok
The only thing you need to do is:
Go to Ngrok website and Download ngrok according your OS.
Unzip it and run it using your localhost port application.
$ ./ngrok http <port>
Then ngrok gives you something similar to this:
ngrok by @inconshreveable (Ctrl+C to quit) Session Status online Update update available (version 2.2.3, Ctrl-U to update) Version 2.1.18 Region United States (us) Web Interface http://127.0.0.1:4040 Forwarding http://58395290.ngrok.io -> localhost:4000 Forwarding https://58395290.ngrok.io -> localhost:4000 Connections ttl opn rt1 rt5 p50 p90 0 0 0.00 0.00 0.00 0.00
Now your local environment is reacheable in internet http://58395290.ngrok.io
If you need to know more about ngrok read the Documentation or list the commands available in your shell with:
$ ./ngrok help
