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.

What should be done if the tweet image does not exist?

How is the content type set when sending the image back to the client?

What steps should be taken to test the image fetching functionality?
