Sounds great! What do I need?

In order to run the app, Coffee-Me, and update the data, there are a couple things to download.

VS Code or similar. We'll use the built-in terminal to clone the Coffee-Me app from GitHub, and run it on both iOS and Android.
Check if you have the Node Package Manager by running "npm -v" in terminal. If not, you'll need to install Node.js
Chrome browser to access the GitHub repo, Google Sheet, and Firebase Console.

Ready, Set, (Expo) Go

With Expo Go, you can run your app on your phone as you make changes. It allow you to, test things like camera and sound - which are not possible with the emulators. Please install this prior to the workshop.

Expo is available for both iOS and Android.

* Available on iPhone, iPad and all Android devices

Questions?

We have answers.

The code will be available here on Oct 21, 2023.

Your laptop and smart phone. Install Expo Go to your phone before class as well as Node.js (we use npm to install various dependencies). It will help if both your devices and yourself are operating on full batteries.

The workshop is action-packed and the better prepared you are, the more we can cover. Also WiFi can act up at the worst moments - so please come prepared with Expo Go on your phone and Node.js installed on your computer.

Yes, the workshop is geared for beginners. The main activities will take place in the browser and on the web. Some familiarity with the command line and code editor such as VS Code or Atom is helpful. But not absolutely necessary.

Yes, I'm looking forward to the day and am happy to answer any questions you may have.
