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).

Local SSL websites on Mac OSX

These instructions will guide you through the process of setting up local, trusted websites on your own computer.

These instructions are intended to be used on Mac OSX Yosemite.

NOTE: You may substitute the edit command for nano, vim, or whatever the editor of your choice is. Personally, I forward edit to Sublime Text:

Building a Maintainable, Agile Architecture for Realtime, Transactional Apps

A maintainable application architecture requires that the UI only contain the rendering logic and execute queries and mutations against the underlying data model on the server. A maintainable architecture must not contain any logic for composing "app state" on the client as that would necessarily embed business logic in the client. App state should be persisted to the database and the client projection of it should be composed in the mid tier, and refreshed as mutations occur on the server (and after network interruption) for a highly interactive, realtime UX.

With GraphQL we are able to define an easy-to-change application-level data schema on the server that captures the types and relationships in our data, and wiring it to data sources via resolvers that leverage our db's own query language (or data-oriented, uniform service APIs) to resolve client-specified "queries" and "mutations" against the schema.

We use GraphQL to dyn

	// Simplest possible wrapper around IHKeyboardAvoiding.

	// I don't really know how to Xcode, but I got it to work by:
	//
	// 1. Checking out the IHKeyboardAvoiding repository.
	// https://github.com/IdleHandsApps/IHKeyboardAvoiding
	//
	// 2. Dragging the Files IHKeyboardAvoiding.{h,m} into my project.
	//
	// 3. Ensuring that both .m files are in the "Compile Sources" phase of the target.
