Free DNS provider with reactjs hosting

I have my own domain which I want to load a web project made in reactjs. I have two doubts:

1. The hosting must have compatibility with reactjs to load the project or is it not important the compatibility of the hosting with the tools used?
2. Is there a dns provider with free hosting included?

I'm new working with this and I don't understand how it works

I use firebase as a provider of dns and hosting but it charges me 7 USD per month and to only perform tests it can be somewhat expensive
