spring-boot-starter VS pullstate

You may find that after getting a good amount of foundational knowledge or experience, books are only good for author perspective. In the wild, maybe you'll benefit more from a boilerplate / starter repo like this or this. Those are called starters / boilerplate repos. That's a good way to get started if the getting started docs of your chosen tech is intimidating or confusing. Here's the one for spring boot.

PullState - https://lostpebble.github.io/pullstate/

Pullstate. It's a lot like svelte's store.

And automatically, any components using uiStateStore.useState and watching the isSidebarOpen property will get updated, exactly the same as the normal useState hook - just shared.

It's so dead simple and has made complex app-building so much easier for me.

The one caveat is that if I have a component with many handlers, e.g. onClick, onMouseMove, onContextMenu, onMouseLeave, etc (and in some cases I do), components can get bloated. I haven't found a fix to that yet. But that's more an inherent issue with react than anything to do with state management.

Sounds like you're on the right track. React is very hire-able. Try out multiple store systems. The big one is react + redux. Then after you have some experience with that, try a simpler one like pullstate.

You could try out pullstate - its basically just global objects which you can mutate and which automatically update your state over your entire app, for whichever parts you have "pulled" the state into.
