## Matomo Web Component

You can install this component via npm:

```bash
npm i @dbp-toolkit/matomo
```

### Usage

```html
<dbp-matomo></dbp-matomo>
<script type="module" src="node_modules/@dbp-toolkit/matomo/dist/dbp-matomo.js"></script>
```

Or directly via CDN:

```html
<dbp-matomo></dbp-matomo>
<script type="module" src="https://unpkg.com/@dbp-toolkit/matomo@0.2.4/dist/dbp-matomo.js"></script>
```

### Attributes

- `endpoint` (required): set to your _Matomo_ server
    - example `<dbp-matomo endpoint="https://my-matomo.tld"></dbp-matomo>`
- `site-id` (required): set to your site id
    - example `<dbp-matomo site-id="456789"></dbp-matomo>`
- `auth` object: you need to set that object property for the login-status
    - example auth property: `{'login-status': 'logged-in'}`
    - note: most often this should be an attribute that is not set directly, but subscribed at a provider
- `analytics-event` object: for sending Matomo events

#### Emitted attributes

The component receives a `analytics-event` attribute to send Matomo events.
It looks like this:

```json
{
    "category": "the category of the event",
    "action": "the action of the event",
    "name": "the name of the event",
    "value": "the value of the event"
}
```

### Tracking actions

```html
<dbp-provider analytics-event>
    <dbp-matomo subscribe="analytics-event"></dbp-matomo>
    <your-dbp-adapter-limt-element-component></your-dbp-adapter-limt-element-component>
</dbp-provider>
```

In your AdapterLitElement component:

```javascript
this.sendSetPropertyEvent('analytics-event', {category: 'my category', action: 'my action'});
```

### Local development

```bash
# get the source
git clone git@github.com:digital-blueprint/toolkit.git
cd toolkit/packages/matomo

# install dependencies (make sure you have npm version 4+ installed, so symlinks to the git submodules are created automatically)
npm install

# constantly build dist/bundle.js and run a local web-server on port 8002
npm run watch

# run tests
npm test

# build local packages in dist directory
npm run build
```

Jump to <http://localhost:8002> and you should get a demo page.
