In this guide, we will go over how to achieve a seamless user experience by rendering a form submission automatically without refreshing the page. The Issue at Hand In your current implementation, you have a form that collects a post title and submits it. However, after submission, the new post does not appear in the list of posts until the page is refreshed. This can lead to a frustrating user experience where changes are not immediately visible. Your initial code structure might look something like this: [[See Video to Reveal this Text or Code Snippet]] Step-by-Step Solution 1. Move the State Management to the Parent Component To manage the post rendering efficiently, we should bring the logic for fetching posts into the App component. This approach allows us to trigger a re-fetch of posts every time a new post is created, ensuring that the latest data is displayed. Updated App Component Modify your App.js as shown below: [[See Video to Reveal this Text or Code Snippet]] 2. Pass Down the Fetch Function You will need to pass a function prop named onCreatePost to the PostCreate component. This prop will call the fetchPosts function after a new post is created.

Ensure the PostList Component Receives Props Finally, ensure that the PostList component now receives the posts data as props: [[See Video to Reveal this Text or Code Snippet]] Conclusion By moving your state management to the parent component and triggering a data refresh after each post submission, you can achieve a dynamic rendering of new posts without refreshing the page. This method is more efficient and creates a smoother user experience, as users will see their new posts immediately after creation. Implement these changes in your React application, and you will see a significant improvement in how you handle form submissions! Happy coding!
