React Observables

There are a few ways to do observables in React.

  1. RxJS
  2. Mobx
  3. Vanilla JS Object.freeze


I’ve been writing MobX for a few weeks now, and in a nutshell, here’s how it works:

  • You create a store (singleton object, constructed using a class) - the observable
  • You observe the store in your components

Vanilla JS

I haven’t tried this with react yet, but vanilla JS allows you to follow the observables pattern. Frontend masters has a course that teaches these patterns pretty well.

Why you might wanna use a library instead of vanilla js

What’s difficult about handling objects?

Svelte stores as an example

Svelte uses JS objects as their store. There’s a lovely tutorial that shows how this is done.
