2015-01-29 Unofficial Relay FAQ

Compilation of questions and answers about Relay from React.js Conf.

Disclaimer: I work on Relay at Facebook. Relay is a complex system on which we're iterating aggressively. I'll do my best here to provide accurate, useful answers, but the details are subject to change. I may also be wrong. Feedback and additional questions are welcome.

What is Relay?

Relay is a new framework from Facebook that provides data-fetching functionality for React applications. It was announced at React.js Conf (January 2015).

If you've reached this page, it's probably because your "parent-based and owner-based contexts differ".

As we've been iterating on React's "context" feature, we've discovered that the parent-based relationship is more useful than the owner-based relationship, so we're migrating to use a parent-based hierarchy.

In short, the owner of a component is whomever creates the component, while the parent of a component is whomever would be the containing ancestor in the DOM hierarchy. To learn more about the owner relationship, see the docs here: http://facebook.github.io/react/docs/multiple-components.html

In many cases, the owner and the parent are the same node, in which case, no further action is necessary.
