UI

MakerKit provides various utilities that allow you to restrict access to certain pages or API according to factors such as sign-in state, role, membership plan, etc.

Protecting Next.js Pages

To protect against access to certain pages, we can use the function withAppProps. This function is a server-side props handler that will take care of checking the following conditions:

if the user is signed in - otherwise will be redirected back to the sign in page (this is customizable)
if the user is onboarded - otherwise will be redirected back to the onboarding
if the page they are trying to access requires a particular membership plan

Assuming you want to protect the Dashboard page, it will be as easy as:


import { withAppProps } from '~/lib/props/with-app-props';
 
export async function getServerSideProps(
  ctx: GetServerSidePropsContext
) {
  return await withAppProps(ctx);
}

You will likely want to add additional logic or additional props to be sent to the page. In this case, you can partially evaluate withAppProps and extend the props with other information:


import { withAppProps } from '~/lib/props/with-app-props';
 
export async function getServerSideProps(
  ctx: GetServerSidePropsContext
) {
  const { props: appProps } =
    await withAppProps(ctx);
 
  const data = await getDataFromDb();
 
  return {
    props: {
      ...appProps,
      data,
    }
  };
}

This handler takes the following parameters:


const DEFAULT_OPTIONS = {
  redirectPath: configuration.paths.signIn,
  locale: 'en',
  localeNamespaces: <string[]>[],
  requirePlans: <string[]>[],
}

redirectPath: by default, we redirect the user to the signIn page when they're not authenticated
redirectPath: by default, we use the en locale
localeNamespaces: additional namespaces you want to add to the route
requirePlans: a list of Stripe price IDs that you may want to require to access this page. If you require more complex logic, it's best to handle it separately

Makerkit's default page guards

withAppProps

The page guard withAppProps is ideal for internal pages of your application, i.e. the pages that require that the user is authenticated and that have an active account; i.e. they went past the onboarding:

This page guard will:

ensure the user is authenticated
ensure the user created an account after the onboarding flow
ensure the user belongs to an organization

withAuthProps

The page guard withAuthProps will disallow users from entering authentication routes (sign-in, sign-up, password-reset) while they are authenticated:

This page guard will:

ensure the user is not authenticated before granting access to pages that require the user not to be authenticated

withTranslationProps

The page guard withTranslationProps is used by default by the other guards and is used to load the translations before rendering the page. Use this as the default guard for static pages that do not have any authentication requirement:

This page guard will:
