# Node.js

## Installation

Add the official Lucky Orange package to your project via NPM:

```bash
$ npm i @luckyorange/server
```

## Usage

After installation, the first step to using Lucky Orange is initializing it with your unique site ID.

```javascript
const LuckyOrange = require('@luckyorange/server')
const luckyorange = new LuckyOrange({ siteId: 'YOUR-SITE-ID' })
```

### Track events

The `track()` method accepts three arguments. The first is the name of the event you wish to track. The second is any arbitrary metadata that you want to associate with the event. Finally, you can send a context object. This allows the event to be associated with a particular user that you have identified or a session created by the Lucky Orange browser library.

```javascript
luckyorange.events.track(
  'Account Created', 
  { acceptedTerms: true }, 
  { userId: 'test-user-123' }
)
```

### Identify users

In order to connect user accounts and their properties in your system with visitor profiles in Lucky Orange, use `identify()`. You must provide a unique ID that will then become an alias for a visitor created internally by Lucky Orange. If you also use `identify()` in the browser tracking code, the same user's behavior will be combined into one profile.

```javascript
luckyorange.visitors.identify('test-user-123', { email: 'test@example.com' })
```
