Build a User Management App with Ionic React

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.

Supabase User Management example

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 Reference > Examples 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.

1
supabase link --project-ref <project-id>
2
# You can get <project-id> from your project's dashboard URL: https://supabase.com/dashboard/project/<project-id>
3
supabase db pull

Get API details#

To interact with data in database tables, you use the client libraries that wrap the auto-generated Data API endpoints, authenticating using the Project URL and key from the project Connect dialog.

Project URL

Publishable key

Read the API keys docs for a full explanation of all key types, their uses, and where to find them.

Building the app#

Start building the React app from scratch.

Initialize an Ionic React app#

Use the Ionic CLI to initialize an app called supabase-ionic-react:

1
npm install -g @ionic/cli
2
ionic start supabase-ionic-react blank --type react
3
cd supabase-ionic-react

Install the only additional dependency: supabase-js

1
npm install @supabase/supabase-js

Save the environment variables in a .env. You need the API URL and the key that you copied earlier.

1
VITE_SUPABASE_URL=YOUR_SUPABASE_URL
2
VITE_SUPABASE_KEY=YOUR_SUPABASE_KEY

With the API credentials in place, create a helper file to initialize the Supabase client. These variables will be exposed in the browser, which is safe because they use a restricted publishable key and the SQL quickstart enables Row Level Security on the profiles table.

src/supabaseClient.ts

1
import { createClient } from '@supabase/supabase-js'
2
3
const supabaseUrl = import.meta.env.VITE_SUPABASE_URL
4
const supabasePublishableKey = import.meta.env.VITE_SUPABASE_PUBLISHABLE_KEY
5
6
if (!supabaseUrl || !supabasePublishableKey) {
7
  throw new Error(
8
    'Missing Supabase environment variables: VITE_SUPABASE_URL and VITE_SUPABASE_PUBLISHABLE_KEY must be set.'
9
  )
10
}
11
12
export const supabase = createClient(supabaseUrl, supabasePublishableKey)

Set up a React component to manage logins and sign ups which uses Magic Links, so users can sign in with their email without using passwords.

Now that you have all the components in place, update App.tsx:

src/App.tsx

1
import { Redirect, Route } from 'react-router-dom'
2
import { IonApp, IonRouterOutlet, setupIonicReact } from '@ionic/react'
3
import { IonReactRouter } from '@ionic/react-router'

    } = supabase.auth.onAuthStateChange(() => {

  return (

      </IonReactRouter>
58
    </IonApp>

  )

export default App

Once that's done, run this in a terminal window:

1
ionic serve

Then open your browser to the URL printed by ionic serve (by default, http://localhost:8100) and you should see the completed app.

Supabase Ionic React

Bonus: Profile photos#

Every Supabase project is configured with Storage for managing large files like photos and videos.

First install two packages in order to interact with the user's camera.

1
npm install @ionic/pwa-elements @capacitor/camera

Capacitor is a cross platform native runtime from Ionic that enables web apps to be deployed through the app store and provides access to native device API.

Ionic PWA elements is a companion package that will polyfill certain browser APIs that provide no user interface with custom Ionic UI.

With those packages installed update index.tsx to include an additional bootstrapping call for the Ionic PWA Elements.

src/index.tsx

1
import React from 'react'
2
import { createRoot } from 'react-dom/client'
3
import App from './App'
4
import { defineCustomElements } from '@ionic/pwa-elements/loader'
5
6
defineCustomElements(window)
7
8
const container = document.getElementById('root')
9
const root = createRoot(container!)
10
root.render(
11
  <React.StrictMode>
12
    <App />
13
  </React.StrictMode>
14
)

Then create an AvatarComponent.
