    Avoiding state flickers in Gatsby applications


    As a user, it can be very disorienting when the "wrong" UI is briefly shown to the user: a login link is shown to an authenticated user, or a 404 error flashes before the page loads correctly. This issue is common in Gatsby applications, because of how Gatsby pre-builds HTML files.

    In this video, we show how issues like this can slip through, and how we can solve the problem by skipping user-specific state during the build. Instead, we'll leave that spot blank, and fill it in later on the client, when we know what should go there.

    While this tutorial uses Gatsby, the same lesson can be applied to Next.js, or any server-rendered React application.
