===Unidirectional data flow===

To support React's concept of unidirectional data flow (which might be contrasted with [[AngularJS]]'s bidirectional flow), the Flux architecture was developed as an alternative to the popular [[model-view-controllermodel–view–controller]] architecture. Flux features ''actions'' which are sent through a central ''dispatcher'' to a ''store'', and changes to the store are propagated back to the view.<ref name="flux">{{cite web|url=https://facebook.github.io/flux/docs/in-depth-overview|title=In Depth OverView|publisher=Facebook|access-date=7 April 2018|website=Flux}}</ref> When used with React, this propagation is accomplished through component properties. Since its conception, Flux has been superseded by libraries such as [[Redux (JavaScript library)|Redux]] and MobX.<ref>{{cite web|title=Flux Release 4.0|url=https://github.com/facebook/flux/releases/tag/4.0.0|website=Github|access-date=26 February 2021}}</ref>

Flux can be considered a variant of the [[observer pattern]].<ref>{{cite web|last1=Johnson|first1=Nicholas|title=Introduction to Flux - React Exercise|url=http://nicholasjohnson.com/react/course/exercises/flux/|website=Nicholas Johnson|access-date=7 April 2018}}</ref>
