Getting Started with React Native in Finland
By React Native Finland
โขFinland has a strong mobile development heritage โ from Nokia's early days to today's thriving startup ecosystem. React Native fits perfectly into this landscape, and the Finnish community is active and welcoming. This guide will help you get started with React Native development in Finland, whether you're a complete beginner or an experienced developer new to the country.
Why React Native?
React Native lets you build native mobile apps using JavaScript and React. Write once, run on both iOS and Android. But unlike hybrid approaches, React Native renders actual native components, giving you the performance and feel of a truly native app.
For Finnish companies, this means:
- Faster development โ One codebase instead of two
- Easier hiring โ JavaScript developers are abundant
- Lower costs โ Less code to maintain
- Native performance โ No compromise on user experience
Learning Resources
University of Helsinki MOOC
The best free React Native course available is right here in Finland. The Mobile Development MOOC from the University of Helsinki is created by the same team behind the famous Full Stack Open course.
The course covers:
- React Native fundamentals
- State management
- Navigation
- Backend integration
- Testing
- App store deployment
It's completely free, self-paced, and you can get university credits for completing it.
Official Documentation
The React Native documentation has improved dramatically and is now an excellent resource. Start with the "Getting Started" guide and work through the fundamentals.
Expo Documentation
If you're using Expo (recommended for beginners), the Expo docs are comprehensive and well-maintained.
Setting Up Your Development Environment
The Easy Way: Expo
For most developers, especially beginners, Expo is the way to go:
npx create-expo-app@latest my-app
cd my-app
npx expo start
Expo handles the complex native build tooling and gives you a great development experience out of the box. You can even test on your physical device without Xcode or Android Studio.
The Full Control Way: React Native CLI
If you need custom native modules or more control:
npx @react-native-community/cli@latest init MyApp
You'll need:
- For iOS: macOS with Xcode installed
- For Android: Android Studio with SDK and emulator
The React Native docs have detailed setup instructions for both platforms.

Your First React Native App
Let's build a simple app to get you started. We'll create a basic counter app with Expo:
npx create-expo-app@latest my-first-app --template blank-typescript
cd my-first-app
Open App.tsx and replace the contents:
const [count, setCount] = useState(0);
return (
<View style={styles.container}>
<Text style={styles.title}>My First RN App</Text>
<Text style={styles.count}>{count}</Text>
<Pressable
style={styles.button}
onPress={() => setCount(count + 1)}
>
<Text style={styles.buttonText}>Increment</Text>
</Pressable>
</View>
);
}
const styles = StyleSheet.create({
container: {
flex: 1,
backgroundColor: '#fff',
alignItems: 'center',
justifyContent: 'center',
},
title: {
fontSize: 24,
fontWeight: 'bold',
marginBottom: 20,
},
count: {
fontSize: 48,
fontWeight: 'bold',
marginBottom: 20,
},
button: {
backgroundColor: '#007AFF',
paddingHorizontal: 24,
paddingVertical: 12,
borderRadius: 8,
},
buttonText: {
color: '#fff',
fontSize: 18,
fontWeight: '600',
},
});
Run it:
npx expo start
Scan the QR code with the Expo Go app on your phone, and you'll see your first React Native app running!
Essential Tools and Libraries
Here are the libraries you'll likely need for any serious app:
Navigation
npx expo install @react-navigation/native @react-navigation/native-stack
npx expo install react-native-screens react-native-safe-area-context
State Management
For simple apps, React's built-in useState and useContext are sufficient. For complex apps:
- Zustand โ Simple and lightweight
- TanStack Query โ For server state
- Redux Toolkit โ If you need the full Redux experience
UI Components
- Tamagui โ Cross-platform UI kit
- NativeWind โ Tailwind CSS for React Native
- React Native Paper โ Material Design components
Forms
npm install react-hook-form zod
Next Steps
Once you've got the basics down:
- Build something real โ The best way to learn is by building
- Join the meetups โ Network and learn from experienced developers
- Contribute to open source โ Many RN libraries welcome contributions
- Read the tutorials โ Check out our articles for more guides
- Get listed โ Add yourself to our developer directory
Getting Help
When you get stuck:
- Read the error message โ React Native error messages are usually helpful
- Search GitHub issues โ Someone's probably encountered the same problem
- Ask on Stack Overflow โ Use the
react-nativetag - Join the community โ Ask at meetups or in online communities
