This example demonstrates how to integrate **Zitadel** using the **[OAuth 2.0 PKCE flow](https://oauth.net/2/pkce/)** to authenticate users securely and maintain sessions across the app. #### Auth library This example uses **[@auth/qwik](https://www.npmjs.com/package/@auth/qwik)**, a Qwik adapter for **[@auth/core](https://www.npmjs.com/package/@auth/qwik)**, a Qwik adapter for **[@auth/core](https://www.npmjs.com/package/@auth/core)** (formerly Auth.js/NextAuth.js), which implements the [OpenID Connect (OIDC)](https://www.npmjs.com/package/@auth/qwik)**, a Qwik adapter for **[@auth/core](https://www.npmjs.com/package/@auth/core)** (formerly Auth.js/NextAuth.js), which implements the [OpenID Connect (OIDC)](https://zitadel.com/docs/apis/openidoauth/endpoints) flow, manages [PKCE](https://www.npmjs.com/package/@auth/qwik), performs token exchange, and exposes helpers for session state. The core library handles authentication across multiple frameworks and provides secure [token storage](https://zitadel.com/docs/apis/openidoauth/endpoints#token_endpoint) with automatic [token refresh](https://www.npmjs.com/package/@auth/qwik)**, a Qwik adapter for **[@auth/core](https://www.npmjs.com/package/@auth/core)** (formerly Auth.js/NextAuth.js), which implements the [OpenID Connect (OIDC)](https://zitadel.com/docs/apis/openidoauth/endpoints) flow, manages [PKCE](https://oauth.net/2/pkce/), performs token exchange, and exposes helpers for session state.

The example includes secure sign-in functionality that redirects users to Zitadel's hosted login page, handles the OAuth callback to exchange authorization codes for [access tokens](https://zitadel.com/docs/apis/openidoauth/endpoints#token-endpoint), and manages sessions with [JWT tokens](https://zitadel.com/docs/apis/openidoauth/endpoints#token-jwt-response) stored in encrypted server-side cookies. Route protection is implemented using [Qwik City's](https://qwik.dev/docs/qwikcity) `onRequest` handler, which performs server-side authentication checks before rendering protected pages. Unauthenticated users attempting to access secured routes are automatically redirected to the login page with a callback URL to return them to their intended destination after successful authentication. The application displays comprehensive user profile information including standard [OIDC claims](https://zitadel.com/docs/apis/openidoauth/claims) like name and email, as well as Zitadel-specific claims such as [organization membership](https://zitadel.com/docs/guides/manage/console/organizations-overview) and [project roles](https://zitadel.com/docs/guides/manage/console/projects-overview). Sign-out functionality implements **[federated logout](https://zitadel.com/docs/guides/integrate/login/oidc/logout)** through Zitadel's end-session endpoint, ensuring that users are logged out from both the application and Zitadel's single sign-on session. The logout process includes [CSRF protection](https://zitadel.com/docs/guides/integrate/login/oidc/logout#csrf-protection) using state parameters validated through secure cookies, followed by proper cleanup of session data and redirection back to the application. --- ## Getting started ### Prerequisites Before running this example, you need to create and configure a PKCE application in the [ZITADEL Management Console](https://zitadel.com/docs/guides/manage/console/console-overview). Follow the PKCE application setup guide to: 1. Create a new Web application in your [Zitadel project](https://zitadel.com/docs/guides/manage/console/projects-overview) 2. Configure it to use the PKCE authentication method 3. Set up your redirect URIs (e.g., `http://localhost:3000/auth/callback/zitadel` for development) 4. Configure post-logout redirect URIs (e.g., `http://localhost:3000/api/auth/logout/callback`) 5. Copy your **Client ID** for use in the next steps > **Note:** Make sure to enable **Dev Mode** in the [ZITADEL Management Console](https://zitadel.com/docs/guides/manage/console/console-overview) if you're using HTTP URLs during local development. For production, always use HTTPS URLs and disable Dev Mode. ### Run the example Once you have your [Zitadel application](https://zitadel.com/docs/guides/manage/console/applications-overview) configured: 1. Clone the [repository](https://github.com/zitadel/example-auth-qwik). 2. Create a `.env.local` file and configure it with the values from your [Zitadel application](https://zitadel.com/docs/guides/manage/console/applications-overview): ``` VITE_PORT=3000 VITE_SESSION_SECRET=your-very-secret-and-strong-session-key VITE_SESSION_DURATION=3600 VITE_ZITADEL_DOMAIN=https://your-instance.zitadel.cloud VITE_ZITADEL_CLIENT_ID=your_client_id_from_console VITE_ZITADEL_CLIENT_SECRET=your-randomly-generated-client-secret VITE_ZITADEL_CALLBACK_URL=http://localhost:3000/auth/callback/zitadel VITE_ZITADEL_POST_LOGOUT_URL=http://localhost:3000/api/auth/logout/callback ``` Replace these values with: - Your actual Zitadel instance URL (the **Issuer** from your [application settings](https://zitadel.com/docs/guides/integrate/login/oidc/login-users)) - The **Client ID** you copied when creating the application - A randomly generated session secret (generate using: `node -e "console.log(require('crypto').randomBytes(32).toString('hex'))"`) - A randomly generated client secret value (Auth.js requires this for internal settings) - The **redirect URI** you configured in the PKCE setup (must match exactly) - The **post-logout redirect URI** you configured (must match exactly) 3. Install dependencies using [npm](https://www.npmjs.com) and start the development server: ```bash npm install npm run dev ``` The application will be available at `http://localhost:3000`. --- ## Learn more and resources * [PKCE concept](https://oauth.net/2/pkce/) * [Federated logout](https://zitadel.com/docs/guides/integrate/login/oidc/logout) * [OIDC integration guide](https://zitadel.com/docs/guides/integrate/login/oidc/login-users) * [Framework docs](https://qwik.dev) * [Auth library (@auth/core)](https://www.npmjs.com/package/@auth/core) * [Qwik adapter (@auth/qwik)](https://www.npmjs.com/package/@auth/qwik) * [Example repository](https://github.com/zitadel/example-auth-qwik)
