How can I use `authProvider.getIdentity()` inside `getServerSideProps` with Next.sj.

Hello! I am using Supabase for auth and Next.js for routing. Is there any way to get the user auth data inside the Next.sj getServerSideProps function? I want to check some claims in my user/jwt in the SS props function but the function returns null. Im assuming it has to do with authProvider mostly working client side? Thanks in advance.

---------------------- Yes, you can get the user auth data inside the Next.js getServerSideProps function. You can use your authProvider's check function inside the server-side function to check if the user is authenticated or not and redirect them to other pages if needed. Here's an example of how to do this:

import { authProvider } from "src/authProvider";

export const getServerSideProps = async (context) => {
  // We've handled the SSR case in our `check` function by sending the `context` as parameter.
  const { authenticated, redirectTo } = await authProvider.check(context);

  if (!authenticated) {
    context.res.statusCode = 401;
    context.res.end();
  }

  if (!authenticated && redirectTo) {
    return {
      redirect: {
        destination: redirectTo,
        permanent: false,
      },
    };
  }

  return {
    props: {
      authenticated,
    },
  };
};

import { authProvider } from "src/authProvider";

export const getServerSideProps = async (context) => {
  // We've handled the SSR case in our `check` function by sending the `context` as parameter.
  const { authenticated, redirectTo } = await authProvider.check(context);

  if (!authenticated) {
    context.res.statusCode = 401;
    context.res.end();
  }

  if (!authenticated && redirectTo) {
    return {
      redirect: {
        destination: redirectTo,
        permanent: false,
      },
    };
  }

  return {
    props: {
      authenticated,
    },
  };
};

This needs to be done for all the routes that you want to protect. You can find more information about handling authentication in Next.js with refine in the documentation (https://refine.dev/docs/packages/documentation/routers/nextjs). Keep in mind that you might need to adjust the authProvider implementation to handle server-side authentication properly, especially if you're using cookies for authentication. You can find an example of how to handle server-side authentication with cookies in the refine documentation (https://refine.dev/docs/packages/documentation/routers/nextjs#server-side-authentication-with-cookies). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------

Thats a pretty good answer, but I need the actual identity data inside the props function, not just if it is authenticated or not.

Also the provided link has an empty section :/

Oops, can you create an issue please? We’ll fix it asap. For now, you can inspired by our nextjs authentication example here: https://refine.dev/docs/examples/next-js/auth/

Authentication | refine

refine allows you to build your SSR supported web applications using Next.js. With this example, you can see how to make a simple refine app in Next.js with Authentication features.

Done! https://github.com/refinedev/refine/issues/4011 I was able to achieve what I wanted by using the Supabase client directly, thanks for the help!

@kapa.ai is there any way to handle this authentication globally to keep the code DRY?

kapa.ai•8mo ago

Let me check the knowledge base for you. One moment! :books: ---------------------- Yes, you can handle authentication globally in your Next.js application with Refine. However, it's important to note that while you can wrap your top-level component with the Authenticated component to handle client-side authentication, server-side authentication must be handled individually for each page using the getServerSideProps function. Here's an example of how you can handle client-side authentication globally:

import { Authenticated } from "@refinedev/core";

const MyApp = ({ Component, pageProps }) => (
  <Authenticated>
    <Component {...pageProps} />
  </Authenticated>
);

export default MyApp;

import { Authenticated } from "@refinedev/core";

const MyApp = ({ Component, pageProps }) => (
  <Authenticated>
    <Component {...pageProps} />
  </Authenticated>
);

export default MyApp;

In this example, all child pages will inherit the requirement to authenticate. However, this only works for client-side. For server-side validation, you still need to use the getServerSideProps function in each page. You can find more information about this in the refine documentation (https://refine.dev/docs/router-integrations/next-js#authentication). ---------------------- Note: you can ask me a follow up question by @ mentioning me again :speech_balloon: ----------------------
