# Installation

## Prerequisites

- **Node.js**: 14.17 or higher (18 LTS recommended)
- **npm** / **yarn** / **pnpm**
- For TypeScript projects: TypeScript 4.7+

## Install from npm

```bash
npm install nomyo-js
```

```bash
yarn add nomyo-js
```

```bash
pnpm add nomyo-js
```

## Browser (CDN)

```html
<script type="module">
  import { SecureChatCompletion } from 'https://unpkg.com/nomyo-js/dist/browser/index.js';
  // ...
</script>
```

---

## Verify Installation

### Node.js

```javascript
import { SecureChatCompletion, getMemoryProtectionInfo } from 'nomyo-js';

const info = getMemoryProtectionInfo();
console.log('Memory protection:', info.method);   // e.g. "zero-only"
console.log('Can lock:', info.canLock);           // true if native addon present

const client = new SecureChatCompletion({ apiKey: 'test' });
console.log('nomyo-js installed successfully');
client.dispose();
```

### CommonJS

```javascript
const { SecureChatCompletion } = require('nomyo-js');
```

## Optional: Native Memory Addon

The pure-JS implementation zeroes buffers immediately after use but cannot prevent the OS from paging sensitive data to swap.
The optional native addon adds `mlock`/`VirtualLock` support for true OS-level memory locking.

```bash
cd node_modules/nomyo-js/native
npm install
npm run build
```

Or if you installed `nomyo-native` separately:

```bash
npm install nomyo-native
```

When the addon is present `getMemoryProtectionInfo()` will report `method: 'mlock'` and `canLock: true`.

## TypeScript

All public APIs ship with bundled type declarations — no `@types/` package required.

```typescript
import {
  SecureChatCompletion,
  ChatCompletionRequest,
  ChatCompletionResponse,
  getMemoryProtectionInfo,
} from 'nomyo-js';
```

## Environment Variables

Store secrets outside source code:

```bash
# .env (never commit this file)
NOMYO_API_KEY=your-api-key
NOMYO_SERVER_URL=https://api.nomyo.ai
NOMYO_KEY_PASSWORD=your-key-password
```

```javascript
import 'dotenv/config';   // or use process.env directly
import { SecureChatCompletion } from 'nomyo-js';

const client = new SecureChatCompletion({
  baseUrl: process.env.NOMYO_SERVER_URL,
  apiKey:  process.env.NOMYO_API_KEY,
});
```
