Tutorial: Designing a GraphQL API

This tutorial was created by Shopify for internal purposes. We've created a public version of it since we think it's useful to anyone creating a GraphQL API.

It's based on lessons learned from creating and evolving production schemas at Shopify over almost 3 years. The tutorial has evolved and will continue to change in the future so nothing is set in stone.

I [tweeted this already][1] but I thought it could use some expansion:

Enable decentralized git workflow: git config alias.serve "daemon --verbose --export-all --base-path=.git --reuseaddr --strict-paths .git/"

Say you use a git workflow that involves working with a core "official" repository that you pull and push your changes from and into. I'm sure many companies do this, as do many users of git hosting services like Github.

Say that server, or Github, goes down for a bit.
