[Fixed]-What is the best way to let someone test your webapp

You can use ngrok — https://ngrok.com/ — to create a public URL to your local server for testing, and then give that URL to people so they can try your webapp.

You can also use Localtunnel to easily share a web service on your local development without deploying the code in the server.

Install the localtunnel

npm install -g localtunnel

Start a webserver on some local port (eg http://localhost:8000) and use the command line interface to request a tunnel to your local server

lt --port 8000

You will receive a url, for example https://xyz.localtunnel.me, that you can share with anyone for as long as your local instance of lt remains active. Any requests will be routed to your local service at the specified port.
