# ZSM Client SDK for React Native

## Contents

This SDK contains the resources needed to learn about Ideem's Universal MFA capabilities, and integrating it into your own React native applications.  These resources include documentation and example applications.

**NOTE:** Prior to integrating the SDK into your own applications, please reach out to Ideem
support, <a href="mailto:support@useideem.com">support@useideem.com</a>, to obtain configuration

---

## Getting Started

### Prerequisites

1. **React Native Version**: `>=0.60`
2. **Node.js Version**: `>=12.0.0`
3. An **Application ID** from Ideem. Reach out to [support@useideem.com](mailto:support@useideem.com) to obtain one.

### Installation

#### 1. Install the Package

```bash
npm install @ideem/zsm-react-native
```

Or with Yarn:

```bash
yarn add @ideem/zsm-react-native
```

#### 2. Link Native Modules

This library uses React Native's auto-linking. However, if manual linking is necessary:
- **iOS**: Add the following to your `Podfile`:
  ```ruby
  pod 'zsm-react-native', :path => '../node_modules/@ideem/zsm-react-native'
  ```
  Then run:
  ```bash
  cd ios && pod install
  ```

- **Android**: No additional setup is required unless auto-linking is disabled.

#### 3. Verify Installation
Check the library is correctly installed and linked:
```bash
react-native doctor
```

### Usage

#### **Basic Integration Example**
Here’s how to initialize and use the SDK:

```javascript
import { UMFAClient } from '@ideem/zsm-react-native';

const config = {
  region: 'YOUR_REGION',
  application_id: 'YOUR_APPLICATION_ID',
  api_key: 'YOUR_API_KEY'
};

const client = new UMFAClient(config);

async function login(username) {
  try {
    const isEnrolled = await client.checkEnrollment(username);
    const token = isEnrolled
      ? await client.authenticate(username)
      : await client.enroll(username);

    console.log('Authentication Token:', token);
  } catch (error) {
    console.error('Error during authentication:', error.message);
  }
}
```

---

## Example Application

You can find example applications in the `examples/` directory. These include:
1. **Basic Authentication**: Demonstrates login and enrollment.
2. **Payment Flow**: Simulates payment using authentication.

To run an example, e.g. for the `umfa` example:
1. Navigate to the example directory:
   ```bash
   cd examples/umfa
   ```
2. Install dependencies:
   ```bash
   npm install
   ```
3. Start the development server:
   ```bash
   npm start
   ```

## Troubleshooting

- **React Native Environment Issues**:
  Ensure your environment is correctly configured for React Native. Refer to the [React Native Environment Setup](https://reactnative.dev/docs/environment-setup).

- **Native Dependency Issues**:
  - Run `pod install` for iOS.
  - Verify your `android/app/build.gradle` for proper linking.
