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).

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

http://www.techmeme.com/070812/p1#a070812p1

The two files are index.php (the homepage) and search.php (the search page)

	#!/bin/bash
	if [ -f ~/Library/KeyBindings/DefaultkeyBinding.dict ]; then
	echo "~/Library/KeyBindings/DefaultkeyBinding.dict already exists"
	exit -1
	fi

	mkdir -p ~/Library/KeyBindings
	cat << EOF > ~/Library/KeyBindings/DefaultkeyBinding.dict
	{
	"₩" = ("insertText:", "\`");

	CAUTION

	This boilerplate code is useless at least about importing dependencies for
	support libraries and Google service libraries. See
	[this post](https://plus.google.com/u/0/+AndroidDevelopers/posts/4Yhpn6p9icf).

	But it is useful for 3rd party libraries that doesn't `aar` yet.
