RxJS vs vuex: What are the differences?
RxJS: The Reactive Extensions for JavaScript. RxJS is a library for reactive programming using Observables, to make it easier to compose asynchronous or callback-based code. This project is a rewrite of Reactive-Extensions/RxJS with better performance, better modularity, better debuggable call stacks, while staying mostly backwards compatible, with some breaking changes that reduce the API surface; vuex: 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.
RxJS belongs to "Concurrency Frameworks" category of the tech stack, while vuex can be primarily classified under "State Management Library".
RxJS and vuex are both open source tools. vuex with 21.2K GitHub stars and 6.9K forks on GitHub appears to be more popular than RxJS with 19.7K GitHub stars and 2.26K GitHub forks.
Flat, Cromon Media Services, and Toucan Toco are some of the popular companies that use vuex, whereas RxJS is used by Portfolium, Free Code Camp, and Onefootball. vuex has a broader approval, being mentioned in 77 company stacks & 255 developers stacks; compared to RxJS, which is listed in 86 company stacks and 230 developer stacks.
