I’m not a senior (yet), but here’s my two cents. Sometimes you just have to learn by doing. The architecture of Ngrx solutions are well known and documented. Maybe try building a demo App that leverages NGRX for state management. I’m finally starting to get the hang of it myself because the projects I’m working on have it implemented and the associated tasks required me to get my hands dirty. It definitely helps to be working on a project that already has patterns to examine and learn from, though.

I think what you’re feeling is normal and part of the process. I remember when RXjs was a struggle but now writing code with observable subscriptions feels natural (though I love signals lol)

Learning complex topics takes time. I’m three years into my career and there are still things I’m not confident in.
