What is Expo?
Expo is a platform for building and deploying React Native apps. Fastshot uses Expo EAS (Expo Application Services) to create native iOS and Android builds from your project.
Setting up Expo
-

What Expo handles
When you deploy from Fastshot, Expo:
- Pulls your latest code from GitHub
- Installs dependencies
- Builds a native binary (APK for Android, IPA for iOS)
- Signs the build with the appropriate certificates
- Provides a download link or submits directly to the store
Build types
| Type | Purpose | Use case |
|---|
| Development | Local testing with dev tools | Debugging on your device |
| Preview | Internal testing | Sharing with testers before release |
| Production | App store submission | Publishing to App Store or Google Play |
Monitoring builds
After starting a build, you can track its progress on the Expo build dashboard. Build logs are available there if anything goes wrong.
