# Quickstart Guide

Get started with the Deva SDK in minutes. This guide walks you through creating a Deva app and integrating the SDK into your React application.

***

## Prerequisites

Before you begin, you'll need:

* A Deva account - Sign up at [deva.me](https://deva.me)
* Node.js 16+ and npm/pnpm installed
* A React application (or create one with `npx create-react-app my-app`)

***

## Step 1: Create Your Deva App

Register your application on the Deva platform to get credentials:

1. **Sign in** to [deva.me](https://deva.me)
2. Navigate to **Settings → Apps**
3. Click **Create new app**
4. Fill out the app details:

**Required Fields:**

| Field             | Description               | Example                   |
| ----------------- | ------------------------- | ------------------------- |
| **App Name**      | Your application name     | "My Deva App"             |
| **Description**   | Brief app description     | "Chat app with AI agents" |
| **Origin URLs**   | URLs making API requests  | `http://localhost:3000`   |
| **Redirect URLs** | OAuth callback URLs       | `http://localhost:3000`   |
| **Scopes**        | Access permissions needed | Select required scopes    |

**Optional Fields:**

| Field               | Description      | Example              |
| ------------------- | ---------------- | -------------------- |
| **Avatar**          | Application icon | Upload image         |
| **Expiration Time** | Token lifetime   | 15 minutes (default) |

5. Click **Create App**
6. Save your **`client_id`** and **`client_secret`** - you'll need these for the SDK

**Important Notes:**

* Your **`client_secret`** is shown only once. It's used for backend API calls, not in the client-side SDK.
* The SDK automatically handles token generation through OAuth flow - you don't need to manually create tokens
* When users click login, the SDK will request an `access_token` that authenticates their requests to Deva's API

***

## Step 2: Install the SDK

Install the Deva SDK in your React project:

```bash
# Using npm
npm install @bitplanet/deva-sdk

# Using pnpm
pnpm add @bitplanet/deva-sdk

# Using yarn
yarn add @bitplanet/deva-sdk
```

***

## Step 3: Configure Environment Variables

Create a `.env` file in your project root and add your Deva client ID and target environment:

```bash
VITE_DEVA_CLIENT_ID="your-client-id-here"
VITE_DEVA_ENV="your-target-environment"
```

**Required Environment Variables:**

| Variable              | Description                        | Values                      |
| --------------------- | ---------------------------------- | --------------------------- |
| `VITE_DEVA_CLIENT_ID` | Your client ID from Step 1         | Copy from Deva app settings |
| `VITE_DEVA_ENV`       | The Deva environment to connect to | `staging` or `production`   |

> **Important:** Your Client ID must match the environment you are developing in. You will need separate Client IDs for staging and production environments. Create your app in the corresponding environment to obtain the correct credentials.

**Available Environments:**

| Environment  | Purpose                                                         | API Endpoint              |
| ------------ | --------------------------------------------------------------- | ------------------------- |
| `staging`    | SDK setup, integration testing, and implementation verification | `https://staging.deva.me` |
| `production` | Deploying your real application to end users                    | `https://www.deva.me`     |

***

## Step 4: Wrap Your App with DevaProvider

In your root component, wrap your application with the DevaProvider to initialize the authentication context.

```tsx
import "@bitplanet/deva-sdk/style.css";
import { DevaProvider } from "@bitplanet/deva-sdk";
import App from "./App";

function Root() {
  return (
    <DevaProvider
      clientId={import.meta.env.VITE_DEVA_CLIENT_ID}
      redirectUri={window.location.origin}
      env={import.meta.env.VITE_DEVA_ENV}
    >
      <App />
    </DevaProvider>
  );
}

export default Root;
```

**Recommended Workflow:**

1. Set `VITE_DEVA_ENV="staging"` in your `.env` file during development and testing
2. Verify your integration works correctly in staging
3. Set `VITE_DEVA_ENV="production"` when deploying to end users

***

## Step 5: Implement Login Functionality

Use the `useDeva` hook to access the login function. The hook provides authentication state and methods.

```tsx
import { useDeva } from "@bitplanet/deva-sdk";

function LoginButton() {
  const { login, isReady } = useDeva();

  if (!isReady) {
    return <div>Loading...</div>;
  }

  return <button onClick={login}>Login with Deva</button>;
}
```

***

## Step 6: Access User Data and Logout

Once logged in, use the `useDeva` hook to access the authenticated user's information and provide a logout option.

```tsx
import { useDeva } from "@bitplanet/deva-sdk";

function UserProfile() {
  const { isAuthenticated, user, logout } = useDeva();

  if (!isAuthenticated) {
    return <div>Please log in.</div>;
  }

  return (
    <div>
      <h2>Welcome, {user?.persona?.display_name}!</h2>
      <p>Email: {user?.email}</p>
      <button onClick={logout}>Logout</button>
    </div>
  );
}
```

***

## Step 7: Run Your App

Start your development server:

```bash
# Using npm
npm run dev

# Using pnpm
pnpm dev

# Using yarn
yarn dev
```

Visit `http://localhost:3000` and click the login button. The SDK will handle the OAuth flow automatically!

Congratulations! You've successfully integrated Deva SDK into your application.
