Redux Observable vs vuex: What are the differences?

Developers describe Redux Observable as "A powerful middleware for Redux using RxJS". It allows developers to dispatch a function that returns an observable, promise or iterable of action(s). Compose and cancel async actions to create side effects and more. On the other hand, vuex is detailed as "Centralized State Management for Vue.js". Vuex is a state management pattern + library for Vue.js applications. It serves as a centralized store for all the components in an application, with rules ensuring that the state can only be mutated in a predictable fashion. It also integrates with Vue's official devtools extension to provide advanced features such as zero-config time-travel debugging and state snapshot export / import.

Redux Observable and vuex can be primarily classified as "State Management Library" tools.

vuex is an open source tool with 21.2K GitHub stars and 6.9K GitHub forks. Here's a link to vuex's open source repository on GitHub.

According to the StackShare community, vuex has a broader approval, being mentioned in 77 company stacks & 255 developers stacks; compared to Redux Observable, which is listed in 15 company stacks and 8 developer stacks.
