Next.js 13 playground

This is a Next.js project bootstrapped with create-next-app.

Changes are made to the default project, to test new features of Next.js 13 and React 18; app routing files, server components, streaming (SSR), transitions.

Features

For better demonstration, API fetches are delayed and NOT cached.

  • /posts page demonstrates the component hierarchy and the usage of Suspense, Fallback and streaming.

    1. The common layout is in view, while posts are loading with the loading component.
    2. Posts are in view, while the UserInfo and the Comments are loading with their own fallbacks.
    3. UserInfo is in view, and Comments is in view.

  • /todos page demonstrates an example of client-side state change causing a refetch to the data source while still making use of SSR.

    1. By clicking the buttons: ALL, DONE, NOT DONE, url changes. (router.push)
    2. Next.js performs client-side navigation to the url, while data fetches are made by the server.
    3. Notice that the button colors change immediately, while the TodoList changes slowly. Also dimmed effect is shown, using isPending, startTransition. Try router.push without them to compare.
