Feature Cost Breakdown

Here's what specific features typically add to your budget:

Authentication & User Management

// Example: Firebase Authentication Setup
import { initializeApp } from 'firebase/app';
import { getAuth, signInWithEmailAndPassword } from 'firebase/auth';

const auth = getAuth(app);

// Sign in existing user
const signIn = async (email, password) => {
  try {
    const userCredential = await signInWithEmailAndPassword(auth, email, password);
    return userCredential.user;
  } catch (error) {
    console.error('Auth error:', error.code);
  }
};

Payment Integration

// Example: Stripe Payment Intent
const createPaymentIntent = async (amount: number, currency: string) => {
  const response = await fetch('/api/create-payment-intent', {
    method: 'POST',
    headers: { 'Content-Type': 'application/json' },
    body: JSON.stringify({ amount, currency }),
  });
  
  const { clientSecret } = await response.json();
  return clientSecret;
};

Cost Optimization Strategies

1. Start with an MVP

Focus on core features first:

MVP Feature Prioritization:
├── Must Have (Launch blockers)
│   ├── User authentication
│   ├── Core functionality
│   └── Payment processing
├── Should Have (First update)
│   ├── Push notifications
│   ├── Analytics
│   └── User profiles
└── Nice to Have (Future releases)
    ├── Social features
    ├── Advanced filters
    └── Gamification
