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?

Core Goals:

• Can test in up-to-date versions of all major browsers
• Can test on up-to-date versions of all major OSes
• Can test in IE9 (because Bootstrap v4 will support IE9+)
• Don't want to have to setup/maintain our own cluster of VMs running all the necessary OSes (and all the versions of Windows)
• Workflow for management of reference/baseline/norm screenshots
