[PropelAuth](https://www.propelauth.com?utm_source=github&utm_medium=library&utm_campaign=nextjs) is a user management and authentication service for your B2B/multi-tenant applications.
PropelAuth is a user management and authentication service for your B2B/multi-tenant applications.
This library provides a simple way to integrate your Next.js application (either AppRouter or Pages) with PropelAuth.
npm install @propelauth/nextjs
Before you start, make sure you have a PropelAuth account. You can sign up for free at here.
Create a file called propelauth.ts in the src directory (or your project's root if you prefer) with the following content:
import {initializeAuth} from "@propelauth/nextjs/server";
const auth = initializeAuth({
authUrl: process.env.NEXT_PUBLIC_AUTH_URL,
redirectUri: process.env.REDIRECT_URI,
integrationApiKey: process.env.INTEGRATION_API_KEY,
verifierKey: process.env.VERIFIER_KEY,
})
export const {
getRouteHandler,
postRouteHandler,
getUser,
getUserOrRedirect,
getUserFromServerSideProps,
validateAccessToken,
validateAccessTokenOrUndefined,
authMiddleware,
} = auth
This file exports all of our server-side functions that you will need to use in your application. You can find all the env variables for your application in the PropelAuth Dashboard under Backend Integration.
In your src/app/api/auth/[slug] directory, create a file called route.ts with the following content:
import {getRouteHandler, postRouteHandler} from "@/auth";
export const GET = getRouteHandler
export const POST = postRouteHandler
In your root layout, src/app/layout.tsx, add the AuthProvider:
export default async function RootLayout({children}: {children: React.ReactNode}) {
return (
<html lang="en">
<AuthProvider authUrl={process.env.NEXT_PUBLIC_AUTH_URL}>
<body className={inter.className}>{children}</body>
</AuthProvider>
</html>
)
}
In your _app.tsx file, add the AuthProvider:
export default function MyApp({Component, pageProps}: AppProps) {
return (
<AuthProvider authUrl={process.env.NEXT_PUBLIC_AUTH_URL}>
<Component {...pageProps} />
</AuthProvider>
)
}
In your src/middleware.ts file, add the following:
import {authMiddleware} from "@/auth";
export const middleware = authMiddleware
// The middleware is responsible for keeping the user session up to date.
// It should be called on every request that requires authentication AND /api/auth/.* routes.
export const config = {
matcher: [
// REQUIRED: Match all request paths that start with /api/auth/
'/api/auth/(.*)',
// OPTIONAL: Don't match any static assets
'/((?!_next/static|_next/image|favicon.ico).*)',
],
}
import {getUser} from "@/auth";
const WelcomeMessage = () => {
const user = getUser()
if (user) {
return <div>Hello {user.firstName}!</div>
} else {
return <div>Please log in to be welcomed</div>
}
}
import {getUserOrRedirect} from "@/auth";
const WelcomeMessage = () => {
// If the user is not logged in, they will be redirected to the login page
const user = getUserOrRedirect()
return <div>Hello {user.firstName}!</div>
}
import {GetServerSideProps, InferGetServerSidePropsType} from "next";
import {getUserFromServerSideProps} from "@/auth";
import {User} from "@propelauth/nextjs/client";
export default function WelcomeMessage({userJson}: InferGetServerSidePropsType<typeof getServerSideProps>) {
// Deserialize the user from the JSON string so you can call functions like user.getOrg()
const user = User.fromJSON(userJson)
return <div>Hello, {user.firstName}</div>
}
export const getServerSideProps: GetServerSideProps = async (context) => {
const user = await getUserFromServerSideProps(context)
if (!user) {
return {redirect: {destination: '/api/auth/login', permanent: false}}
}
return { props: {userJson: JSON.stringify(user) } }
}
"use client";
import {useUser} from "@propelauth/nextjs/client";
const WelcomeMessage = () => {
const {loading, user} = useUser()
if (loading) {
return <div>Loading...</div>
} else if (user) {
return <div>Hello {user.firstName}!</div>
} else {
return <div>Please log in to be welcomed</div>
}
}
Note that this works on both the client and server's User object, but the below example is on the server.
If you are curious where the organization information comes from, check out our documentation on organizations. The quick answer is:
// src/app/org/[slug]/page.tsx
import {getUserOrRedirect} from "@/auth";
export default async function AdminOnlyPage({ params }: { params: { slug: string } }) {
const user = await getUserOrRedirect()
const org = user.getOrgByName(params.slug);
const isAdmin = org?.isRole("Admin")
if (!isAdmin) {
return <div>Not found</div>
} else {
return <div>Welcome {user.firstName}, Admin of {org?.orgName}</div>
}
}
"use client"
import {useLogoutFunction} from "@propelauth/nextjs/client";
export default function LogoutButton() {
const logoutFn = useLogoutFunction()
return <button onClick={logoutFn}>Logout</button>
}
If you don't want to use redirect functions, you can also use useHostedPageUrls which will return the URLs instead of redirecting.
"use client"
import {useRedirectFunctions} from "@propelauth/nextjs/client";
export default function SignupAndLoginButtons() {
const {redirectToSignupPage, redirectToLoginPage} = useRedirectFunctions()
return <>
<button onClick={redirectToSignupPage}>Sign up</button>
<button onClick={redirectToLoginPage}>Log in</button>
</>
}
PropelAuth also provides you with pre-built account and organization management UIs. You can redirect your users to these pages by using the following functions:
"use client"
import {useRedirectFunctions} from "@propelauth/nextjs/client";
export default function AccountAndOrgButtons() {
const {redirectToAccountPage, redirectToOrgPage} = useRedirectFunctions()
return <>
<button onClick={redirectToAccountPage}>Account</button>
<button onClick={redirectToOrgPage}>Organization</button>
</>
}
