This example provides the steps to build a simple user management app (from scratch!) using Supabase and Angular. It includes:
- Supabase Database: a Postgres database for storing your user data.
- Supabase Auth: users can sign in with magic links (no passwords, only email).
- Supabase Storage: users can upload a photo.
- Row Level Security: data is protected so that individuals can only access their own data.
- Instant APIs: APIs will be automatically generated when you create your database tables.
By the end of this guide you'll have an app which allows users to login and update some basic profile details:
Clicking this button the application will:
- Launch and prepare the Postgres database in Supabase.
- Launch the app in Vercel.
- Fork the example into your own GitHub account.
- Prepare the deployed application with all the necessary environment variables.
If you want to do it yourself, let's get started!
Whenever you get stuck at any point, take a look at this repo.
Before we start building we're going to set up our Database and API. This is as simple as starting a new Project in Supabase and then creating a "schema" inside the database.
- Go to app.supabase.io.
- Click on "New Project".
- Enter your project details.
- Wait for the new database to launch.
Now we are going to set up the database schema. We can use the "User Management Starter" quickstart in the SQL Editor, or you can just copy/paste the SQL from below and run it yourself.
Now that you've created some database tables, you are ready to insert data using the auto-generated API.
We just need to get the URL and
anon key from the API settings.
Let's start building the Angular app from scratch.
We can use the Angular CLI to initialize
an app called
Then let's install the only additional dependency: supabase-js
And finally we want to save the environment variables in the
All we need are the API URL and the
anon key that you copied earlier.
These variables will be exposed on the browser, and that's completely fine since we have Row Level Security enabled on our Database.
Now that we have the API credentials in place, let's create a SupabaseService with
ng g s supabase to initialize the Supabase client and implement functions to communicate with the Supabase API.
And one optional step is to update the CSS file
src/index.css to make the app look nice.
You can find the full contents of this file here.
Let's set up a Angular component to manage logins and sign ups. We'll use Magic Links, so users can sign in with their email without using passwords.
Create an AuthComponent with
ng g c auth Angular CLI command.
After a user is signed in we can allow them to edit their profile details and manage their account.
Create an AccountComponent with
ng g c account Angular CLI command.
Now that we have all the components in place, let's update AppComponent:
Once that's done, run this in a terminal window:
And then open the browser to localhost:4200 and you should see the completed app.
Every Supabase project is configured with Storage for managing large files like photos and videos.
Let's create an avatar for the user so that they can upload a profile photo.
Create an AvatarComponent with
ng g c avatar Angular CLI command.
And then we can add the widget on top of the AccountComponent html template:
At this stage you have a fully functional application!
