🚀 From Clone to App Store: The Complete Expo Project Journey
Ever cloned an Expo project and wondered what all those commands actually do? You're not alone! The journey from git clone to a production app involves several distinct stages, each with its own purpose and magic. Let's break down this workflow so you can navigate it with confidence. 🧭
🎯 Stage 1: Project Acquisition & Setup
📥 git clone https://github.com/...
This copies the entire project repository from GitHub to your local machine. Think of it as downloading the blueprint for your app.
Label: Cloning
📂 cd project-name
Navigate into the project directory. This is your new workspace where all the magic happens!
📦 npm install
This critical step reads package.json and downloads all the project dependencies into node_modules. Without this, your project is like a car without an engine.
Label: Installing Dependencies
💻 Stage 2: The Development Loop
🔥 npx expo start
Starts the Expo Development Server (Metro Bundler). It bundles your JavaScript code, creates a development tunnel, and provides the developer UI with QR codes.
Label: Starting the Dev Server
📱 Press i (iOS) / a (Android) / w (Web)
Quick shortcuts to launch your app on simulators, emulators, or web browsers using the Expo Go app.
Label: Launching on Simulator/Emulator
⚡ Hot Reloading / Fast Refresh
The magic sauce! When you save a file, Metro instantly sends updates to your running app. No manual reloading needed - pure developer bliss! ✨
🏗️ Stage 3: Building for Production
🏗️ npx expo prebuild
Generates the native iOS and Android project folders based on your app.config.js. Use this when you need to customize native code.
Label: Prebuilding Native Projects
☁️ eas build --platform all
The modern way! EAS Build uses Expo's cloud service to compile your iOS .ipa and Android .apk/.aab files. No local Xcode/Android Studio headaches! 🎉
Label: Building Production Binaries
📤 Stage 4: Distribution & Deployment
🧪 Internal Testing
Share your production build with testers using TestFlight (iOS) and Internal Testing Tracks (Google Play).
🚀 eas update
This is Expo's superpower! For JavaScript-only changes, this pushes updates directly to users, bypassing app store reviews. Mind-blowing! 🤯
Label: OTA (Over-The-Air) Updates
🏪 App Store Submission
The final step - submitting your production binaries to Apple App Store and Google Play Store for public distribution. You made it! 🎊
✨ The Big Picture
From git clone to eas build, each command plays a crucial role in transforming code into a real, working application. Understanding this workflow turns confusion into confidence! 🥳
