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 to use it to host a HTML file for another one of my projects. Also, anybody know how to create a HTML file on a Mac? Thanks in advance. Or, If I can't use NGROK, anybody know something as easy and free is it is that I could use for hosting a HTML file on my computer. I need to be able to change the file in real time, so google sites and stuff like that are out of the question.
No. ngrok only tunnels traffic, so it can't actually serve the HTML file for you.
You can, however, serve a directory of files very easily. One of the quickest ways to start a server is with python. From the command line, cd to the directory containing your HTML files and run:
$ python3 -m http.server
Or for python 2:
$ python -m SimpleHTTPServer
Then, in another terminal, run ngrok.
