Supabase Integration
Supabase Authentication (commonly referred to as Supabase Auth) is a complete user authentication and management system provided by the platform. It enables developers to easily achieve user registration, sign-in, identity authentication, and access control features without building these complex security systems from scratch.
This guide provides developers with step descriptions for quickly integrating Supabase Auth with Next.js full stack development, and offers a deployment template for development reference. The following context introduces the integration steps in detail to quickly complete the user management feature development in the project.
Getting Started
You can select the Supabase Auth integration template provided by Makers to quickly enter development. Click the Supabase Auth Starter template. This tutorial is roughly divided into three steps: Supabase configuration, integration details, and local development debugging. The following sections detail the specific operations for each step.
1. Preparing Supabase
If you are first time exposed to Supabase, see our Supabase Integration Guide to obtain account signup and environment initialization complete process.
The Authentication feature provided by the Supabase platform efficiently manages user data. Access the Authentication management interface via the left navigation pane, where you will see the pre-configured user data table and related settings. This interface supports core features such as email verification process, access Policies, and Session parameters. To learn more about specific features, see the official documentation for details.

2. One-Click Deployment
Go to the template page Supabase Auth Starter, click
Deploy, and log in to enter the console deployment page. In the console deployment configuration panel, you need to fill in the environment variables obtained above.
When "Congratulations!" appears, it indicates deployment success. Deployment typically takes about 1 minute. If the project fails during deployment, you can modify the project based on
Build Logs and Build Summary information, or contact staff to resolve the issue.
After successful deployment, go to the project homepage and copy the
Domain. Go to the Supabase console and navigate to the URL configuration section. Copy your domain name info to the Site URL field. This way, after registration completion, users will be auto-redirected to your website homepage.
Integration Details
After deployment, the system will create an appropriate code repository under the user's GitHub account. This section introduces the project implementation details, convenient for you to conduct follow-up feature integration and development.
Downloading Code
Go to your Github repository, copy the Clone address, and run in the terminal:
git clone https://github.com/${your-github-account}/supabase-auth-startercd supabase-auth-starter
Core Feature Introduction
This is a user authentication solution template built based on Supabase and Next.js. Some webpage of the project use server-side rendering (SSR) architecture, providing user registration, sign-in, and session management features.
1. User Sign-up and Login
Registration feature (
signup/page.tsx): Users create new account through mailbox and passwordLogin feature (
signin/page.tsx): Registered users authenticate through credentialsLogout feature (
signout/route.js): Securely purge user sessions and authentication status2. Cookie Authentication Logic
The project uses an HTTP Cookies-based session management mechanism to underwrite secure transmission of user status between client and server. Cookie setting policy:
access_token: User access token used for API request authenticationrefresh_token: Refresh token for session auto-renewaluser_id: Unique user identifierCookie security configuration:
// Production environment configuration{path: '/',maxAge: 604800, // 7-day valid periodhttpOnly: true, // prevent XSS attacksecure: true, // HTTPS transmissionsameSite: 'lax' // CSRF protection}
3. API Routing Architecture
signin/route.js: Handle user login requests, verify credentials, and set authentication cookiessignup/route.js: Handle user registration requests and create a new user accountuser/route.js: Verify user authentication status and return current user infosignout/route.js: Handle user logout and purge ALL authentication cookiesLocal Development and Debugging
After downloading the project to your local system and parsing its details, the developer may need to develop locally, debug, or preview it.
To enable local debugging, you also need to configure environment variables, which can be cumbersome. In this case, you can use EdgeOne CLI. It can synchronize the configuration information deployed on EdgeOne Makers to your local environment and also deploy the project locally.
Using EdgeOne CLI needs to be installed and log in. For details, see the document introduction of EdgeOne CLI.
