Supabase’s official Angular walkthrough builds a client-side user-management app with email magic-link authentication, profile data, and photo uploads. Its example disables server-side rendering (SSR), so it is a browser-side quickstart—not an SSR authentication recipe.
What this quickstart builds
Supabase’s Angular user-management tutorial combines three Supabase services:
- Database: Postgres tables hold application data, with Row Level Security (RLS) policies controlling which rows users can access.
- Auth: users sign in with email magic links, and the app reads authentication state.
- Storage: users can upload a profile photo.
The tutorial also includes profile editing. It is a concrete example for a browser-rendered Angular app, rather than a generic setup for every authentication method or rendering architecture.
1. Create a Supabase project and schema
Create a project in Supabase, then set up the database schema used by the application. The official walkthrough offers a “User Management Starter” quickstart in the SQL Editor or the SQL included in the guide. Follow the schema instructions there so the example’s profile data and access rules match the app.
#1 Best Overall
Do not treat creating tables as sufficient authorization. Enable RLS and configure policies that define which authenticated users may read or change each row. For profile data, policies should express the intended ownership rule—for example, restricting a user’s access to the row associated with that user’s authenticated identity. The exact policy must match the schema and operations in your project; use the tutorial’s SQL rather than applying a policy blindly.
2. Generate the Angular app and install the client
The official walkthrough uses Angular CLI to create an app named supabase-angular with routing and standalone components disabled, CSS styling, and SSR disabled. It then adds the Supabase JavaScript client.
ng new supabase-angular --routing false --style css --standalone false --ssr false
cd supabase-angular
npm install @supabase/supabase-jsCLI prompts and generated project structure can vary by Angular CLI release. If the command asks questions differently or options are unavailable in your installed version, follow the current Angular CLI prompts and the current Supabase tutorial rather than assuming a particular release’s defaults.
3. Configure the project URL and publishable key
In the Supabase project’s connection details, copy the project URL and publishable key. The tutorial stores these values in an Angular environment file and uses them when creating the client. Keep the values separate from application logic so the client service can read a single configuration source.

A publishable key identifies the client; it does not grant safe access by itself or replace database authorization. Never put a secret or service-role key in an Angular environment file, source bundle, or any other code shipped to users. Use RLS policies to enforce data access.
4. Create a Supabase client service
Make an Angular service responsible for initializing the Supabase client from the configured URL and publishable key. The tutorial’s service also provides app-facing functions for the authentication, profile, and Storage operations, keeping Supabase calls out of unrelated components.
Rank #3
Use the API calls and types shown in the current official Angular walkthrough as you implement the service. Exact generated files and API details may change across framework and client releases; do not assume a snippet written for another version will match your project.
5. Add sign-in, account, and profile features
Email magic-link authentication
The example lets a user sign up or sign in by email and follow a magic link. Add the tutorial’s authentication component and connect it to the client service. The app also tracks authentication state at the application level so its account UI can respond when a user signs in or out.

The account component retrieves and edits the user’s profile information, while profile-photo uploads use Supabase Storage. Configure Storage access according to the same principle as database access: the policies must express which authenticated users may upload, view, or change files. A client-side component alone is not an access-control boundary.
How authentication and RLS work together
Supabase’s JavaScript client sends the user’s Auth token with data requests. When RLS is enabled, Postgres evaluates the policies you have defined against that request, allowing access to be scoped row by row. The token supplies identity context; the policy determines what that identity can do. See the Supabase Auth documentation alongside the tutorial’s schema and policies.
Choose an Auth method based on what the app needs. Supabase documents distinct uses for getClaims (verified token claims), getUser (a user fetched from Auth), and getSession (session tokens and expiry). A session’s returned user object should not, by itself, be treated as authorization proof when storage is shared with a client. Consult the current Auth docs for the API details and use the method appropriate to your trust boundary.
6. Run the app locally
After completing the tutorial’s components and service wiring, start the Angular development server with the script generated for your project:
ng serveOpen the local address reported by the CLI, then test the full flow: request a magic link, authenticate, view or edit the profile, and upload a photo. If an operation fails, check the browser console and Supabase logs, then verify the project URL and publishable key, schema, RLS policies, and Storage policies. A successful sign-in does not prove that a database or file policy permits the operation.
What changes if your Angular app uses SSR?
The tutorial explicitly creates the app with --ssr false. Its browser-client setup should not be carried over as a server-side session pattern: server rendering needs a verified approach for handling session cookies and requests. The cited Angular walkthrough does not establish that SSR integration. Supabase’s getting-started documentation is a useful entry point to current platform guidance, but use a specifically documented SSR/session pattern for your framework setup rather than extrapolating from browser storage.
Where to go next
For an Ionic Angular application, Supabase lists a separate Ionic Angular tutorial in its Getting Started documentation. The Angular walkthrough described here is the direct client-side route; it does not establish that the Ionic path or an SSR approach is interchangeable.
