Workshop exercises for the Chain React 2026 Intermediate Workshop.

How to use this repo

1. Fork the companion repo. You'll start working right on main.
2. Start at the first module by opening up the file starting with "01-".
3. Do the rest of the modules in order.

Prerequisites

• A local development environment ready for native iOS and Android React Native / Expo development, capable of running the npx expo run:ios and npx expo run:android, including recent versions of:
  • Xcode (version 26.4+)
  • Watchman
  • Cocoapods
  • JDK 17
  • Android Studio
  • iOS simulator
  • Android emulator
  • If you're not sure if you have all of these or if you have the right versions, check the Expo Local App Development requirements for details on how to install these tools in order to enable local native development with the Expo CLI.
• Other general development tools:
  • Node LTS version (22+)
  • Visual Studio Code
  • Git (Github Desktop works great)
• Hardware:
  • A Mac is highly recommended for the full experience. You will not be able to do some of the exercises without access to an iOS device or simulator.
  • Simulators/emulators will work just fine for all the exercises, but bringing an Android or iOS device to test on is great, too!
• pnpm

Test your setup before the workshop

Do these steps to ensure you'll be able to complete the workshop exercises.

1. Fork and clone the template repo.

2. Restore dependencies with

pnpm install

3. Build and run the app on your iOS simulator:

npx expo run:ios

4. Build and run the app on your Android emulator:

npx expo run:android

If these steps don't work, refer to the Expo Local Development guide.

Want to run on a device? If you want to do some or all of the workshop on a device, you can also test with npx expo run:ios --device and/or npx expo run:android --device.
