Build a User Management App with Ionic Vue
This tutorial demonstrates how to build a basic user management app. The app authenticates and identifies the user, stores their profile information in the database, and allows the user to log in, update their profile details, and upload a profile photo. The app uses:
- Supabase Database - a Postgres database for storing your user data and Row Level Security so data is protected and users can only access their own information.
- Supabase Auth - allow users to sign up and log in.
- Supabase Storage - allow users to upload a profile photo.

If you get stuck while working through this guide, refer to the full example on GitHub.
Project setup#
Before you start building you need to set up the Database and API. You can do this by starting a new Project in Supabase and then creating a "schema" inside the database.
Create a project#
- Create a new project in the Supabase Dashboard.
- Enter your project details.
- Wait for the new database to launch.
Set up the database schema#
Now set up the database schema. You can use the "User Management Starter" quickstart in the SQL Editor, or you can copy/paste the SQL from below and run it.
- Go to the SQL Editor page in the Dashboard.
- Click User Management Starter under the Community > Quickstarts tab.
- Click Run.
You can pull the database schema down to your local project by running the db pull command. Read the local development docs for detailed instructions.
1supabase link --project-ref <project-id>2# You can get <project-id> from your project's dashboard URL: https://supabase.com/dashboard/project/<project-id>3supabase db pullGet API details#
Now that you've created some database tables, you are ready to insert data using the auto-generated API.
To do this, you need to get the Project URL and key from the project Connect dialog.
Read the API keys docs for a full explanation of all key types and their uses.
Changes to API keys
Supabase has changed the way keys work to improve project security and developer experience. You can read the full announcement on GitHub.
They will be deprecated by the end of 2026, and you should now use the publishable (sb_publishable_xxx) and secret (sb_secret_xxx) keys instead.
In most cases, you can get keys from the Project's Connect dialog, but if you want a specific key, you can find them in the Settings > API Keys section of the Dashboard.
- For new keys, open the API Keys tab, if you don't have a publishable key already, click Create new API Keys, and copy the value from the Publishable key section for client-side operations. For server-side operations, copy the value from the Secret keys section.
- For legacy keys, copy the
anonkey for client-side operations and theservice_rolekey for server-side operations from the Legacy API Keys tab.
Building the app#
Start by building the Vue app from scratch.
Initialize an Ionic Vue app#
Use the Ionic CLI to initialize an app called supabase-ionic-vue:
1npm install -g @ionic/cli2ionic start supabase-ionic-vue blank --type vue3cd supabase-ionic-vueInstall the only additional dependency: supabase-js
1npm install @supabase/supabase-jsSave the environment variables in a .env file, including the API URL and key that you copied earlier.
1VUE_APP_SUPABASE_URL=YOUR_SUPABASE_URL2VUE_APP_SUPABASE_KEY=YOUR_SUPABASE_KEYWith the API credentials in place, create a helper file to initialize the Supabase client. These variables will be exposed on the browser, and that's fine since Supabase enables Row Level Security on Databases by default.
src/supabase.ts
1import { createClient } from '@supabase/supabase-js'23const supabaseUrl = process.env.VUE_APP_SUPABASE_URL4const supabaseKey = process.env.VUE_APP_SUPABASE_KEY56if (!supabaseUrl) {7 throw new Error(8 'Environment variable VUE_APP_SUPABASE_URL is not set. Please define it before starting the application.'9 )10}1112if (!supabaseKey) {13 throw new Error(14 'Environment variable VUE_APP_SUPABASE_KEY is not set.

Create a Vue component to manage logins and sign ups that uses Magic Links, so users can sign in with their email without using passwords.

After a user has signed in, let them edit their profile details and manage their account with a new component called Account.vue.

With all the components in place, update App.vue and the app routes:
The Supabase Auth SDK contains three different functions for authenticating user access to applications:
Summary of the methods#
- Use
getClaimsto protect pages and user data. It reads the access token from storage and verifies it. Locally via the WebCrypto API and a cached JWKS endpoint when the project uses asymmetric signing keys (the default for new projects), or by callinggetUsersolely to validate when symmetric keys are in use. The returned claims always come from decoding the JWT, not from a user lookup. getUsermakes a network call to the project's Auth instance to get the user record, which includes the most up-to-date information about the user at the cost of a network call.getSessionwhen you need the raw session (the access token, refresh token, and expiry). For example to forward the access token to another service. The session is loaded directly from local storage and isn't re-validated against the Auth server, so the embedded user object shouldn't be trusted on its own when storage is shared with the client (cookies, request headers). To verify identity, validate the access token withgetClaims, or callgetUserfor a fresh, server-confirmed user record.
In summary: use getClaims to verify identity (typically for protecting pages and data), getUser when you need an up-to-date user record from the Auth server, and getSession when you need the access or refresh token directly, but don't rely on the user object it returns for authorization decisions.

Bonus: Profile photos#
Every Supabase project is configured with Storage for managing large files like photos and videos.
Create an upload widget#
First install two packages to interact with the user's camera.
1npm install @ionic/pwa-elements @capacitor/cameraCapacitor is a cross-platform native runtime from Ionic that enables you to deploy web apps to app stores and provides access to native device API.
Ionic PWA elements is a companion package that polyfills certain browser APIs that provide no user interface with custom Ionic UI.
With those packages installed, update main.ts to include an additional bootstrapping call for the Ionic PWA Elements.
