## Usage
vue-emoji-picker is a slot-based component, to provide maximum flexibility.
Since every ounce of html is created by a consumer (ie. you), you can customize every piece of the component as you wish.

### Very simple usage, without any CSS defined
You will need two things. A textarea (or an input), where emojis will be injected, and a component declaration. A simple example is provided below.
```html
<textarea v-model="input"></textarea>

<emoji-picker @emoji="insert" :search="search">
  <div slot="emoji-invoker" slot-scope="{ events: { click: clickEvent } }" @click.stop="clickEvent">
    <button type="button">open</button>
  </div>
  <div slot="emoji-picker" slot-scope="{ emojis, insert, display }">
    <div>
      <div>
        <input type="text" v-model="search">
      </div>
      <div>
        <div v-for="(emojiGroup, category) in emojis" :key="category">
          <h5>{{ category }}</h5>
          <div>
            <span
              v-for="(emoji, emojiName) in emojiGroup"
              :key="emojiName"
              @click="insert(emoji)"
              :title="emojiName"
            >{{ emoji }}</span>
          </div>
        </div>
      </div>
    </div>
  </div>
</emoji-picker>
```

```js
{
  data() {
    return {
      input: '',
      search: '',
    }
  },
  methods: {
    insert(emoji) {
      this.input += emoji
    },
  },
}
```

As you may see, you have to declare some things yourself. Namely:
- `input` - a model for your input/textarea,
- `search` - a model for the search box inside the component (optional),
- `insert(emoji)` - a method responsible to put emojis into your input/textarea. Provided `emoji` is a string representation of the emoji to be inserted.

### CSS-styled example
To see what is possible with the component, you can simply have a look at a demo available [here](https://codepen.io/DCzajkowski/pen/jzLzWp).

## Available props
- `search` _optional_ - If you are not using the search functionality, you can omit this one. It should be a model of the search passed from your `data`.
- `emojiTable` _optional_ - You can overwrite the [default](https://github.com/DCzajkowski/vue-emoji-picker/blob/master/src/emojis.js) emoji table by providing your own.

## Slots
- `emoji-invoker`
  - `events` - delares the `v-on:click` toggle of the picker box,
- `emoji-picker`
  - `emojis` - object of unicode emojis,
  - `insert()` - method to be invoked when an emoji is clicked,
  - `display` - object containting `x`, `y` and `visible` properties.
