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).

import Prelude

public struct Lens<A, B> {
    private let get: A -> B
    private let set: (A, B) -> A

    public init(get: A -> B, set: (A, B) -> A) {
        self.get = get
        self.set = set
    }
