We recently released an exciting new feature at DeckDeckGo.

In addition to being able to deploy your presentations online as progressive web apps, our web open-source editor can now push your source code to GitHub, too.

This new function runs on Cloud Functions for Firebase. Because we like to share our discoveries, here are the key things we learned while developing this integration.
