Is it possible to host, instead of a web app, a HTML file with NGROK? I really don\'t know anything about NGROK, I just used it to host a server for a Twilio app, and am wanting
Yes. ngrok now has a built-in fileserver. https://ngrok.com/docs#http-file-urls
Their example command Linux/mac:
ngrok http -auth="user:password" file:///Users/alan/share
Windows:
ngrok http -auth="user:password" "file:///C:\Users\alan\share"
This will create an HTTP server with a basic auth username and password, sharing all files in the directory /Users/alan/share
