How to Add Authentication to an Angular 16 App with Supabase

If you are building an Angular 16 app and want to add user authentication, Supabase is a great option to consider. Supabase is an open source Firebase alternative that provides a set of tools for building scalable web and mobile applications. In this article, we will walk through the steps to add authentication to an Angular 16 app using Supabase.

Step 1: Create a Supabase Account

The first step is to create a Supabase account. You can sign up for a free account at https://supabase.io/. Once you have created an account, you will be able to create a new project and obtain the project URL and public key, which you will need to configure authentication in your Angular 16 app.

Step 2: Install the Supabase Angular SDK

Next, you will need to install the Supabase Angular SDK in your Angular 16 app. You can do this using npm:

npm install @supabase/supabase-js @supabase/supabase-angular

Step 3: Configure Supabase in Your Angular 16 App

After installing the Supabase Angular SDK, you will need to configure it in your Angular 16 app. You can do this by creating a new file, for example, supabase.config.ts, and adding the following code:

    const SUPABASE_URL = 'your_supabase_project_url';
    const SUPABASE_KEY = 'your_supabase_public_key';

    import { createClient } from '@supabase/supabase-js';

    export const supabase = createClient(SUPABASE_URL, SUPABASE_KEY);
    

Step 4: Implement Authentication in Your Angular 16 App

Now that Supabase is configured in your Angular 16 app, you can start implementing authentication features such as sign up, sign in, and sign out. You can refer to the official Supabase documentation for detailed instructions on how to do this: https://supabase.io/docs/guides/auth

Step 5: Test the Authentication Functionality

Once you have implemented authentication in your Angular 16 app, it’s time to test the functionality. You can create test user accounts and verify that the sign up, sign in, and sign out features are working as expected.

Conclusion

Adding authentication to an Angular 16 app with Supabase is a straightforward process. By following the steps outlined in this article, you can quickly and easily implement user authentication in your app and provide a secure and seamless experience for your users.
