I created a video course that addresses the exact problem you're describing and shows you how to build a full multi-page app backed by a database (but it's for Angular rather than React).

When I was learning I saw the same thing you're still seeing — most tutorials only explain high-level concepts and when they do show code examples, they are tiny, arbitrary, and unrealistic. So when I quit my job to teach web development, I wanted to make sure I didn't do the same thing as everyone else.
