The title &quot;GraphQL&#x2F;Relay Wins. Flux&#x2F;Redux Considered Harmful&quot; is obviously clickbait. Relay is clearly superior to Redux&#x2F;Flux for data fetching and object storage, and that isn&#x27;t shocking to anyone who has looked into both of them. But Relay isn&#x27;t there yet (Relay is soon going to bring time travel, has no way to manage local state, etc). With redux coming in at 2kb, there&#x27;s no reason no to use both relay &amp; redux. This isn&#x27;t about winning, and Redux is by no means obsolete (yet).
