Building the app

Start with building the Angular app from scratch.

Initialize an Angular app

Use the Angular CLI to initialize an app called supabase-angular setting some defaults that you can change to suit your needs:

npx ng new supabase-angular --routing false --style css --standalone false --ssr false
cd supabase-angular

Install supabase-js:

npm install @supabase/supabase-js

Create a src/environments directory and save API URL and key that you copied earlier as environment variables in a new src/environments/environment.ts file.

The application exposes these variables in the browser, and that's fine as Supabase enables Row Level Security by default on all tables.

<$CodeSample path="/user-management/angular-user-management/src/environments/environment.ts" lines={[[1, -1]]} meta="name=src/environments/environment.ts" />

With the API credentials in place, create a SupabaseService with ng g s supabase and add the following code to initialize the Supabase client and implement functions to communicate with the Supabase API.

<$CodeSample path="/user-management/angular-user-management/src/app/supabase.service.ts" lines={[[1, -1]]} meta="name=src/app/supabase.service.ts" />

Optionally, update src/styles.css to style the app. You can find the full contents of this file in the example repository.

Set up a login component

You need an Angular component to manage logins and sign ups. The component uses Magic Links, so users can sign in with their email without using passwords.

You can customize other emails sent out to new users, including the email's looks, content, and query parameters from the Authentication > Email section of the Dashboard.

Create an AuthComponent with the ng g c auth Angular CLI command and add the following code.

<$CodeTabs>

<$CodeSample path="/user-management/angular-user-management/src/app/auth/auth.component.ts" lines={[[1, -1]]} meta="name=src/app/auth/auth.component.ts" />

<$CodeSample path="/user-management/angular-user-management/src/app/auth/auth.component.html" lines={[[1, -1]]} meta="name=src/app/auth/auth.component.html" />

</$CodeTabs>

Account page

Users also need a way to edit their profile details and manage their accounts after signing in. Create an AccountComponent with the ng g c account Angular CLI command and add the following code.

<$CodeTabs>

<$CodeSample path="/user-management/angular-user-management/src/app/account/account.component.ts" lines={[[1, 16], [27, -1]]} meta="name=src/app/account/account.component.ts" />

<$CodeSample path="/user-management/angular-user-management/src/app/account/account.component.html" lines={[[1, 1], [3, -1]]} meta="name=src/app/account/account.component.html" />

</$CodeTabs>

Profile photos

Add a way for users to upload a profile photo. Supabase configures every project with Storage for managing large files like photos and videos.

Create an upload widget

Create an AvatarComponent with the ng g c avatar Angular CLI command and add the following code.

<$CodeTabs>

<$CodeSample path="/user-management/angular-user-management/src/app/avatar/avatar.component.ts" lines={[[1, -1]]} meta="name=src/app/avatar/avatar.component.ts" />

<$CodeSample path="/user-management/angular-user-management/src/app/avatar/avatar.component.html" lines={[[1, -1]]} meta="name=src/app/avatar/avatar.component.html" />

</$CodeTabs>

Update the Account component

With the Avatar component created, update AccountComponent to include it:

<$CodeTabs>

<$CodeSample path="/user-management/angular-user-management/src/app/account/account.component.ts" lines={[[1, -1]]} meta="name=src/app/account/account.component.ts" />

<$CodeSample path="/user-management/angular-user-management/src/app/account/account.component.html" lines={[[1, -1]]} meta="name=src/app/account/account.component.html" />

</$CodeTabs>

You also need to change app.module.ts to include the ReactiveFormsModule from the @angular/forms package.

<$CodeSample path="/user-management/angular-user-management/src/app/app.module.ts" lines={[[1, -1]]} meta="name=src/app/app.module.ts" />

Launch!

With all the components in place, change the contents of AppComponent to include the new components and Auth logic:

<$Partial path="auth_methods.mdx" />

<$CodeTabs>

<$CodeSample path="/user-management/angular-user-management/src/app/app.component.ts" lines={[[1, -1]]} meta="name=src/app/app.component.ts" />

<$CodeSample path="/user-management/angular-user-management/src/app/app.component.html" lines={[[1, -1]]} meta="name=src/app/app.component.html" />

</$CodeTabs>

Now run the application in a terminal:

npm run start

Open the browser to localhost:4200 and you should see the completed app.

At this stage you have a fully functional application!
