React Canaries : livraison incrémentale de fonctionnalités hors de Meta

3 mai 2023

Traditionnellement, les nouveautés de React n’étaient d’abord disponibles qu’au sein de Meta, pour arriver plus tard dans les livraisons open source. Nous aimerions offrir à la communauté React un moyen d’adopter individuellement des fonctionnalités plus en amont, alors que leur conception est quasi finalisée —  un peu comme l’utilisation que Meta fait de React en interne. Nous présentons donc un nouveau canal de livraison officiel appelé Canary. Il permet à des environnements choisis tels que les frameworks de découpler leur adoption de fonctionnalités React individuelles du calendrier officiel de sortie de React.
