Facebook has open sourced a technical preview of Relay, its framework that enables declarative data fetching and updates for React applications. Relay v0.1.1 can be downloaded from GitHub together with a starter kit with the components you need to try it out.
Facebookâs React.js user interface library became open source in 2013. Now Facebook is open sourcing the framework it has developed to manage data and client applications. It supplies the "missing piece" for developers working with React.js - how to get data to and from the server.
The announcement of the Relay Technical Preview, Joseah Savona explains:
While React simplified the process of developing complex user-interfaces, it left open the question of how to interact with data on the server. It turns out that this was a significant source of friction for our developers; fragile coupling between client and server caused data-related bugs and made iteration harder. Furthermore, developers were forced to constantly re-implement complex async logic instead of focusing on their apps. Relay addresses these concerns by borrowing important lessons from React: it provides declarative, component-oriented data fetching for React applications.
To clarify the README.md on GitHub states:
In this talk at the recent React Europe conference, Joseph Savona explores the problems Relay solves, its architecture and query lifecycle, and shows how Relay powers applications as complex as the Facebook News Feed. Skip the first two minutes to get to the point at which the technical hitch is solved and the presentation itself starts.
As well as the Technical Preview, there is also a Relay Starter Kit on GitHub that includes an app server, a GraphQL server and a transpiler that you can use to get started building an app with Relay plus a link to the Relay tutorial that walk you through using the kit.
