You&#x27;re not wrong: things do change quickly in the JavaScript world. But have you actually been following this stuff very closely?<p>&quot;Flux&quot; was never a &quot;well-known default,&quot; because there was no single &quot;Flux&quot; library - only Facebook&#x27;s little written guide and an implementation of the dispatcher (a small part of the overall Flux architecture).<p>So, there were about 500 different implementations of &quot;Flux&quot; - none of which I&#x27;d say were ever considered a &quot;well-known default&quot; (the biggest ones - Reflux, Alt, Marty, Flummox, and Fluxxor - all have roughly between 1000 - 3000 stars on GitHub).<p>Then, Redux came on the scene and became the first and only &quot;well-known default&quot;. Several of the Flux libraries I just mentioned actually deprecated themselves and put up notices to use Redux instead. As of the time of this writing Redux has almost 13,000 stars on GitHub.<p>Relay&#x2F;Falcor are really part of an entirely different thing than React; they are about replacing the traditional REST API with an entirely new paradigm.
