Expo Go
How does the QR code scanning feature work in Expo Go?
You run a command on your computer, and a QR code appears in your terminal. Open the Expo Go app on your phone, scan the code with your camera, and your project loads over Wi-Fi. It’s incredibly fast and makes testing feel like magic.
Can I share my app with friends using Expo Go?
Yes, you can generate a temporary link that lets anyone with Expo Go open your project on their phone. I showed my roommate a basic to-do list app, and he could interact with it instantly without any cables or accounts.
What should I do if my app gets stuck on the splash screen after an update?
This usually happens due to a compatibility issue with the latest Expo SDK or a missing dependency. Try clearing the app cache on your phone, restarting the Expo CLI, and running npm update to sync your project with the current version.
Why is my project not loading in Expo Go even though the QR code scans?
First, ensure your phone and computer are on the same Wi-Fi network. If it still fails, check your firewall settings and try using the tunnel connection option in Expo CLI, which can bypass network restrictions.
How does Expo Go compare to using Xcode or Android Studio for testing?
Expo Go is much simpler and faster for beginners since you don't need a developer account or cables. However, it lacks access to all native modules, so for advanced features like Bluetooth or custom native code, you'll eventually need Xcode or Android Studio.
