You see I had a little problem when I started out I had just learnt Node.Js and started to write the code for this in Node but then I wanted free hosting and I started out with firebase because of it being free so that I could provide the service for free. But Firebase hosting is not like VPS so Its like you only have access to var/www/ and its an apache/ngnix server. So the app.js file I had written was to be dumped.
Necessity is the mother of invention.
And then came a thought how do you handle any random value added to domain as jointest.ml/authgc/ you can’t create this many folder.
But one way you could do that was by configuring the Error page to deliver tests with our fav JavaScript. That’s what I did using Firebase Data Base as data storage and window.location.pathname as identifier. Later I realized that this would also help in WebCrawlers finding out page and devouring the free limit firebase had given me! (yeah!, a true genius our mind is).
So if you want to create your own Google Forms let me tell you it can be free. But might require a lot of real work. Sip a coffee and sit in a chair , relax and think start working night long. Stack Overflow is there my friend!
