## 3. Create a React app

Create a React app using a [Vite](https://vitejs.dev/guide/) template.

```bash
npm create vite@latest my-app -- --template react
```

## 4. Install Supabase's Agent Skills (optional)

Supabase's [Agent Skills](/docs/guides/ai-tools/ai-skills) is a curated set of instructions that give your AI agent procedural knowledge about working with Supabase.

Install them so your AI coding agent can produce more accurate, reliable code using current Supabase patterns, such as authentication, server-side rendering, and database migrations, rather than relying solely on training data.

To install, run the following command in the root of your project:

```bash
npx skills add supabase/agent-skills
```

## 5. Install the Supabase client library

The fastest way to get started is to use the `supabase-js` client library, which provides a convenient interface for working with Supabase from a React app.

Navigate to the React app and install `supabase-js`.

```bash
cd my-app && npm install @supabase/supabase-js
```

## 6. Declare Supabase environment variables

Create a `.env.local` file and populate it with your Supabase URL and publishable key that you can get from the helper below, or [from the project **Connect** panel](/dashboard/project/_?showConnect=true&framework=react&connectTab=frameworks)

<Button variant="primary" asChild>
  <a href="/dashboard/project/_?showConnect=true&connectTab=frameworks&framework=react">
    Open Connect panel
  </a>
</Button>

```text name=.env.local
VITE_SUPABASE_URL=<SUBSTITUTE_SUPABASE_URL>
VITE_SUPABASE_PUBLISHABLE_KEY=<SUBSTITUTE_SUPABASE_PUBLISHABLE_KEY>
```

<$Partial path="api_settings.mdx" variables={{ "framework": "react", "tab": "frameworks" }} />

## 7. Query data from the app

Replace the contents of `App.jsx` with a `getInstruments` function that fetches the data and displays the query result on the page using a Supabase client.

```js name=src/App.jsx
import { createClient } from '@supabase/supabase-js'
import { useEffect, useState } from 'react'

const supabase = createClient(
  import.meta.env.VITE_SUPABASE_URL,
  import.meta.env.VITE_SUPABASE_PUBLISHABLE_KEY
)

function App() {
  const [instruments, setInstruments] = useState([])

  useEffect(() => {
    getInstruments()
  }, [])

  async function getInstruments() {
    const { data, error } = await supabase.from('instruments').select()

    if (error) {
      console.error(error)
      return
    }

    setInstruments(data)
  }

  return (
    <ul>
      {instruments.map((instrument) => (
        <li key={instrument.name}>{instrument.name}</li>
      ))}
    </ul>
  )
}

export default App
```

## 8. Start the app

Run the development server, go to http://localhost:5173 in a browser, and you should see the list of instruments.

```bash
npm run dev
```
