We are delighted to be joined by two amazing engineers from the Firebase team, who visit us from the US especially for this meetup.

**Important**

BRING YOUR LAPTOP!

**Workshop description**

Diana and Rachel will lead a workshop in which participants can bring their own laptops and try out one of the most requested Firebase features, local emulation for testing and development. Participants will walk through writing Firestore security rules and a Firebase Function to make failing tests pass. In the process, participants will learn about local testing with Firebase, which is traditionally tricky for managed services; about how to extend the tests to become part of a CI setup; about securing a Firebase app, given the different security model; and how to build reliable and scalable Firebase Functions. Diana and Rachel are also happy to answer other questions about Firebase.
