SwiftUI and Node.js Full Stack - Build Twitter - iOS 16 - Tweet Image Visualize

In this episode, we learn how to implement a function to fetch and display images for tweets. The process is similar to handling user profile images. We define a GET route with parameters to identify the tweet and image. The function checks if the tweet and image exist, handles errors using try-catch, and sends the image data back to the client with the correct content type. Testing is done using Postman and a browser to ensure the functionality works as expected.
