海外TECH	DEV Community	Next.js Redirect Without Flashing Content	https://dev.to/theodorusclarence/next-js-redirect-without-flashing-content-5bio	Next js Redirect Without Flashing ContentNext js prerenders the static page then hydrate the site to full interactivity client sideThat means we see our page first which is the HTML and the CSS and a split second later we get the JavaScript and all of the interactivity like button clicks The ProblemIn Create React App redirecting or doing history push is not really a problem because all of the data that was sent is fetch on the client side including the static page HTML amp CSS So there won t be any flashing content and the app will smoothly redirect or push the page But in Next js we get the static page first then only after finishing the hydration the javascript code that does the redirecting will run This becomes a problem when we are making a page with an authentication barrier because the unauthorized user can see the content briefly before getting redirected I saw a lot of this problem even in the production app maybe they still cover up the data because some of it was fetched client side but the shell sometimes still shows up Try opening this website You are not supposed to have access to this page You will see a flash of the dashboard shell then only after that flash you will get redirected to the login page There are a lot of answers lying around the internet to use methods such as server side rendering the page and utilizing cookies by using dangerouslySetInnerHTML in the Head This method of blocking the page does not need any of that but we will need to have a full page loader to block the content SolutionI created a demo on You can try opening up the page and directly go to learn auth redirect nextjs vercel app blocked You will briefly see the loader then get redirected to the route There are approach that I found Checking on every single pageimport useEffect from react import useRouter from next router import useAuth from contexts auth import FullPageLoader from components FullPageLoader export default function blocked const router useRouter const isAuthenticated user logout isLoading useAuth useEffect gt if isLoading amp amp isAuthenticated router push isAuthenticated isLoading if isLoading isAuthenticated return lt FullPageLoader gt return lt div className py space y layout gt lt h gt YOUR CONTENT THAT SHOULD NOT BE SEEN UNLESS AUTHENTICATED lt h gt lt div gt Here we are getting the isAuthenticated from the Auth Context you can see the repository for more details This set of code will return the FullPageLoader component first while waiting for the page rendered and getting hydrated then after that the useEffect will do the checking if we are authenticated This code is using useEffect in the Authentication Context to verify the token that is usually stored in localStorage If you want to see this Authentication Context pattern I have a code snippet for that The context are returning isLoading Value and we show the loader when it is loading until we get the value of isAuthenticated This pattern will effectively block the content that we don t want to give to unauthorized users But using the first approach it will be painful to add that pattern to every authenticated page we have So I try to create a PrivateRoute kind of similar to the CRA s React Router pattern Using PrivateRoute Componentimport useEffect from react import useRouter from next router import useAuth from contexts auth import FullPageLoader from FullPageLoader export default function PrivateRoute protectedRoutes children const router useRouter const isAuthenticated isLoading useAuth const pathIsProtected protectedRoutes indexOf router pathname useEffect gt if isLoading amp amp isAuthenticated amp amp pathIsProtected Redirect route you can point this to login router push isLoading isAuthenticated pathIsProtected if isLoading isAuthenticated amp amp pathIsProtected return lt FullPageLoader gt return children By using this component we can specify the routes that we want to protect in app js app jsimport SEO from next seo config import styles globals css import AuthProvider from contexts auth import PrivateRoute from components PrivateRoute function MyApp Component pageProps Add your protected routes here const protectedRoutes blocked component return lt gt lt AuthProvider gt lt PrivateRoute protectedRoutes protectedRoutes gt lt Component pageProps gt lt PrivateRoute gt lt AuthProvider gt lt gt export default MyApp I m open for all suggestions and contributions to improve Open a PR on the repository or email me at theodorusclarence gmail com DemoWithout using full page loader amp not authenticated blocked unhandledAs you can see the red text is still flashed brieflyUsing full page loader amp not authenticated blocked componentUsing full page loader no content will be flashedUsing full page loader amp authenticated by checking the tokenUsing full page loader will still work if they have the token in localStorage	2021-05-18 15:25:14
