<Admonition type="note">
If you get stuck while working through this guide, you can find the [full example on GitHub](https://github.com/supabase/supabase/tree/master/examples/user-management/react-user-management).
</Admonition>
<$Partial path="project_setup.mdx" variables={{ "framework": "react", "tab": "frameworks" }} />
## Building the app
Start building the React app from scratch.
### Initialize a React app
Use [Vite](https://vitejs.dev/guide/) to initialize an app called `supabase-react`:
```bash
npm create vite@latest supabase-react -- --template react
cd supabase-react
```
Install [supabase-js](https://github.com/supabase/supabase-js):
```bash
npm install @supabase/supabase-js
```
Save the environment variables in a `.env.local` file, using the Project URL and the key that you copied [earlier](#get-api-details).
<$CodeSample
path="/user-management/react-user-management/.env.example"
lines={[[1, -1]]}
meta="name=.env"
/>
With the API credentials in place, create a helper file to initialize the Supabase client. The application exposes these variables in the browser, and that's fine as Supabase enables [Row Level Security](/docs/guides/database/postgres/row-level-security) by default on all tables.
Create and edit `src/supabaseClient.js`:
<$CodeSample
path="/user-management/react-user-management/src/supabaseClient.js"
lines={[[1, -1]]}
meta="name=src/supabaseClient.js"
/>
### App styling (optional)
An optional step is to update the CSS file `src/index.css` to make the app look better.
You can find the full contents of this file [in the example repository](https://raw.githubusercontent.com/supabase/supabase/master/examples/user-management/react-user-management/src/index.css).
### Set up a login component
You need a React component to manage logins and sign-ups. It uses [Magic Links](/docs/guides/auth/auth-email-passwordless#with-magic-link), so users can sign in with their email without using passwords.
<Admonition type="tip" label="Did you know?">
You can customize other emails sent out to new users, including the email's looks, content, and query parameters from [the **Authentication > Email**](/dashboard/project/_/auth/templates) section of the Dashboard.
</Admonition>
Create and edit `src/Auth.jsx`:
<$CodeSample
path="/user-management/react-user-management/src/Auth.jsx"
lines={[[1, -1]]}
meta="name=src/Auth.jsx"
/>
### Account page
After a user signs in, they need a way to edit their profile details and manage their accounts.
Create a new component called `src/Account.jsx` and add the following code:
<$CodeSample
path="/user-management/react-user-management/src/Account.jsx"
lines={[[1, 2], [4, 66], [74, -1]]}
meta="name=src/Account.jsx"
/>
## Profile photos
Add a way for users to upload a profile photo. Supabase configures every project with [Storage](/docs/guides/storage) for managing large files like photos and videos.
### Create an upload widget
Create `src/Avatar.jsx` and add the following code:
<$CodeSample
path="/user-management/react-user-management/src/Avatar.jsx"
lines={[[1, -1]]}
meta="name=src/Avatar.jsx"
/>
### Update the Account component
With the Avatar component created, update `src/Account.jsx` to include it:
<$CodeSample
path="/user-management/react-user-management/src/Account.jsx"
lines={[[1, -1]]}
meta="name=src/Account.jsx"
/>
### Launch!
With all the components in place, change the contents of `src/App.jsx` to include the new components and Auth logic.
<$Partial path="auth_methods.mdx" />
<$CodeSample
path="/user-management/react-user-management/src/App.jsx"
lines={[[1, -1]]}
meta="name=src/App.jsx"
/>
Once that's done, run this in a terminal window:
```bash
npm run dev
```
And then open the browser to [localhost:5173](http://localhost:5173) and you should see the completed app.

At this stage you have a fully functional application!
