I already finished development of my site. It was made using HTML, CSS3, jquery and javascript. Like many others it has a form to clients send their projects to my email. Making a simple research, some sites indicates the use of NodeJS and teaches how to configure and program a server application. Fine.
Doing another research to decide web-hosting company, most of them directs me to a VPS hosting plan which enables use of NodeJS. I don't need a plan like this just to enable a form and uses ajax to parse a JSON file to generate some divs.
Do I need to use NodeJS to use form and JSON in my site?
This is my first site and even doing a research I have this doubts.
