If it is for short term, you can use localtunnel (same like ngrok)

Just follow these steps (require: NodeJS)  :

1. Install localtunnel by running

   $ npm install -g localtunnel

2. Assumes, your app is running on http://localhost:8080/, then run

   $ lt --port 8080 It will create a public url domain with random name like this.

NOTE: You can create custom url as well (eg: $ lt --port 4200 -s "sangeeth")

-s means subdomain

Tada !!, it's done !!!
