How do I implement authentication in a React Navigation app using TypeScript?

To implement authentication, you can use React Navigation's stack and tab navigators along with context or state management for user sessions.

Can you provide a code example for setting up a login screen?

Sure! Here's a simple example:

import React, { useState } from 'react';
import { View, TextInput, Button } from 'react-native';

const LoginScreen = () => {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');

  const handleLogin = () => {
    // Handle login logic here
  };

  return (
    <View>
      <TextInput placeholder='Email' value={email} onChangeText={setEmail} />
      <TextInput placeholder='Password' secureTextEntry value={password} onChangeText={setPassword} />
      <Button title='Login' onPress={handleLogin} />
    </View>
  );
};

This sets up a basic login form.

How do I manage user sessions after login?

You can use React Context or libraries like Redux to manage user sessions. Store the user data in context and provide it to your app.

What about protecting routes that require authentication?

You can create a higher-order component (HOC) that checks if the user is authenticated before rendering the protected routes.
