MVVM Architecture in React Native: Is It Worth It?

As React Native apps grow in complexity, maintaining clean and scalable architecture becomes essential. One popular architecture pattern borrowed from native development is MVVM (Model-View-ViewModel). But is it worth using in a JavaScript or TypeScript environment?

Let’s break it down β€” what MVVM means in React Native, how to structure it, and when the MVVM architecture makes sense to adopt it.

πŸ” What Is MVVM?

MVVM stands for:

  • Model – The data and business logic layer (e.g. API calls, data transformation)
  • View – The UI (React Native components)
  • ViewModel – Acts as a bridge between View and Model, managing state and exposing it to the View

In React Native, the ViewModel is often implemented using Hooks or classes, depending on your preference.

πŸ“¦ Example Folder Structure (React Native + TypeScript)

src/
β”œβ”€β”€ models/           # Data interfaces, DTOs
β”œβ”€β”€ viewmodels/       # Custom hooks or classes that handle state
β”œβ”€β”€ views/            # Screens & components
β”œβ”€β”€ services/         # API, storage, utilities
β”œβ”€β”€ navigation/       # Navigation config
β”œβ”€β”€ App.tsx

🧠 Example: Login Screen with MVVM

🧩 1. Model (LoginPayload.ts)

export interface LoginPayload {
  email: string;
  password: string;
}

🧠 2. ViewModel (useLoginViewModel.ts)

import { useState } from 'react';
import { LoginPayload } from '../models/LoginPayload';

export function useLoginViewModel() {
  const [form, setForm] = useState({ email: '', password: '' });
  const [loading, setLoading] = useState(false);

  const handleChange = (field: keyof LoginPayload, value: string) => {
    setForm(prev => ({ ...prev, [field]: value }));
  };

  const login = async () => {
    setLoading(true);
    try {
      // fake API call
      await new Promise(res => setTimeout(res, 1000));
      alert('Login Success');
    } catch (err) {
      alert('Login Failed');
    } finally {
      setLoading(false);
    }
  };

  return { form, loading, handleChange, login };
}

πŸ“± 3. View (LoginScreen.tsx)

import React from 'react';
import { View, TextInput, Button, ActivityIndicator } from 'react-native';
import { useLoginViewModel } from '../viewmodels/useLoginViewModel';

export const LoginScreen = () => {
  const { form, loading, handleChange, login } = useLoginViewModel();

  return (
    
       handleChange('email', text)}
      />
       handleChange('password', text)}
      />
      {loading ? (
        
      ) : (
        

βœ… Pros of MVVM in React Native

  • βœ… Separation of concerns: UI logic is isolated
  • βœ… Easier to test and mock business logic
  • βœ… Reusable view models across screens
  • βœ… Cleaner code when managing complex state

❌ Cons of MVVM in React Native

  • ❌ Overhead for small/simple apps
  • ❌ Slight learning curve for new devs
  • ❌ Can lead to unnecessary abstraction if overused

🧠 When Should You Use MVVM?

Project TypeMVVM Worth It?
Simple apps❌ Not needed
Medium-sized appsβœ… Helpful
Large-scale appsβœ… Absolutely
Team projectsβœ… Consistency

If you have business logic, stateful flows, or reusable logic across screens, MVVM architecture in React Native can bring real clarity to your project.

🏁 Conclusion

MVVM isn’t β€œrequired” in React Native, but it’s incredibly helpful once your app grows beyond a few screens. By introducing ViewModels via custom hooks or classes, you get better testability, clearer structure, and a cleaner separation of concerns.

If you’re already using context, Redux, or Zustand β€” MVVM can sit on top as an organizing principle rather than a replacement.

Try it in one screen and see how it improves your code clarity.
