In this episode, we make it possible to edit a post and have those changes instantly show up for all users, in real time. We start by updating our edit post form so that when we hit edit, the form is pre-filled with the current post content, making editing super user-friendly. We also go through the necessary validation and authorization steps to ensure only the right users can make changes.
Once editing works, we focus on making updates efficient and real-time. Instead of refreshing all posts when one is edited, we wire things up so only the updated post component is refreshed. This means less data sent over the network and a much snappier UI. We demonstrate both the correct approach (refreshing the individual component) and the less efficient way (refreshing all posts) to help you see the difference.
To make things real-time across different clients, we use events and broadcast channels. We walk step-by-step through setting up channels per post, so each post update only notifies the clients who care about that specific post. At the end, you'll see seamless, instant post editing updates that just affect the right part of the page for everyone viewing — perfect for modern interactive applications!
