HTML Templating in Firebase

I am creating a simple blog on Firebase. I cannot find any documentation or examples on best practices on how to create HTML templates for all of my posts. Here’s what I’m thinking

  • For each new post I just create a new HTML page and copy and paste my old HTML as a template

I dont think that this is the correct way in doing this. I guess my question just really boils down to this

How do I manage creating new ‘posts’ in a static HTML website?
