How can I use fetch in React Native for advanced scenarios?

You can use the fetch API in React Native to handle advanced scenarios like authentication, error handling, and pagination. Would you like to know more about a specific aspect?

Yes, can you explain how to handle authentication with fetch?

To handle authentication, you typically need to include an authorization header in your fetch request. For example:

fetch('https://api.example.com/data', {
  method: 'GET',
  headers: {
    'Authorization': 'Bearer YOUR_TOKEN',
  },
})
.then(response => response.json())
.then(data => console.log(data));

This way, you can securely access protected resources.

What about error handling?

For error handling, you can check the response status and throw an error if it's not in the 200 range. Here's an example:

fetch('https://api.example.com/data')
  .then(response => {
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    return response.json();
  })
  .then(data => console.log(data))
  .catch(error => console.error('There was a problem with your fetch operation:', error));
