const app = createApp(App);

app.use(WideAngle, {
  siteId: "8D27G3B9ACA01F4241",
  domain: "stats.example.com",
  fingerprint: true,
  supressDnt: true
});
```


# Usage 

The Wide Angle Analytics provides an instance of `waa` which can be then injected to your component. 

```javascript
import { inject } from 'vue'
const waa = inject('waa');
```

You will find a fully functional example in this [repository](sample/vue-sample).


## Tracking Pageviews

No action necessary. The tracker script automatically issues **Page View** and **Page Leave** events.

## Tracking Events 

Wide Angle supports three specialized events:
* clicks
* downloads 
* custom actions

Site has to have these event enable in Wide Angle Analytics configuration prior to usage. Otherwise the tracker script will not sent these events. Consult [official documentation](https://wideangle.co/documentation/tracking-custom-actions) regarding how to enable event handling. 

### Tracking Clicks 

Currently **Click Events** are [emitted automatically](https://wideangle.co/documentation/tracking-click-events) based on element data attributes. 

| :warning:  The tracker script does not listen to events inside shadow DOM. This is known limitation to be addressed in near term. |
|--------------------------------------------------------------------------------------------------------------------------------------------|

### Tracking Downloads

Depending on the configured mode, the **Download Event** will fire automatically when either:
* a file with recognized extension is being downloaded, or
* when a link is marked with `data-waa-name` attribute.

| :warning:  Currently the tracker script does not listen to events inside shadow DOM. This is known limitation to be addressed in near term. |
|--------------------------------------------------------------------------------------------------------------------------------------------|

### Tracking Custom Actions

Custom action are the most flexible and can be triggered directly from Vue components. As such their usage is not limitted due to Shadow DOM.

Example:

```vue
<template>
  <button @click="sendEvent()">Send Event</button>    
</template>

<script setup>
import { inject } from 'vue'
const waa = inject('waa');
const sendEvent = async () => {
  const params = {
    session: 'cjhw92nf9aq',
    cohort: 'c1233'
  }  
  waa.dispatchEvent('interest', params);  
}
</script>
```
