## Components

### Launcher

`Launcher` is the only component needed to use vue-beautiful-chat. It will react dynamically to changes in messages. All new messages must be added via a change in props as shown in the example.

| *isOpen | Boolean | The bool indicating whether or not the chat window should be open. |
| *open | Function | The function passed to the component that mutates the above mentioned bool toggle for opening the chat |
| *close | Function | The function passed to the component that mutates the above mentioned bool toggle for closing the chat |
| messageList | [message] | An array of message objects to be rendered as a conversation. |
| showEmoji | Boolean | A bool indicating whether or not to show the emoji button
| showFile | Boolean | A bool indicating whether or not to show the file chooser button
| showDeletion | Boolean | A bool indicating whether or not to show the edit button for a message
| showEdition | Boolean | A bool indicating whether or not to show the delete button for a message

| colors | Object | An object containing the specs of the colors used to paint the component. [See here](#faq)

#### Events

|event | params   | description |
|-----|--------|---------------|
| onType | undefined | Fires when user types on the message input |
| edit | `message` | Fires after user edited message |

#### Slots

##### header

Replacing default header.

```vue
<template v-slot:header>
  🤔 Good chat between {{participants.map(m=>m.name).join(' & ')}}
</template>
```

##### user-avatar

Replacing user avatar.
Params: `message`, `user`

```vue
<template v-slot:user-avatar="{ message, user }">
  <div style="border-radius:50%; color: pink; font-size: 15px; line-height:25px; text-align:center;background: tomato; width: 25px !important; height: 25px !important; min-width: 30px;min-height: 30px;margin: 5px; font-weight:bold" v-if="message.type === 'text' && user && user.name">
    {{user.name.toUpperCase()[0]}}
  </div>
</template>
```

##### text-message-body

Change markdown for text message.
Params: `message`

```vue
<template v-slot:text-message-body="{ message }">
  <small style="background:red" v-if="message.meta">
    {{message.meta}}
  </small>
  {{message.text}}
</template>
```

##### system-message-body

Change markdown for system message.
Params: `message`

```vue
<template v-slot:system-message-body="{ message }">
  [System]: {{message.text}}
</template>
```

### Message Objects

Message objects are rendered differently depending on their type. Currently, only text, emoji and file types are supported. Each message object has an `author` field which can have the value 'me' or the id of the corresponding agent.

```javascript
{
  author: 'support',
  type: 'text',
  id: 1, // or text '1'
  isEdited: false,
  data: {
    text: 'some text',
    meta: '06-16-2019 12:43'
  }
}

{
  author: 'me',
  type: 'emoji',
  id: 1, // or text '1'
  isEdited: false,
  data: {
    code: 'someCode'
  }
}

{
  author: 'me',
  type: 'file',
  id: 1, // or text '1'
  isEdited: false,
  data: {
    file: {
      name: 'file.mp3',
      url: 'https:123.rf/file.mp3'
    }
  }
}
```


#### Quick replies

When sending a message, you can provide a set of sentences that will be displayed in the user chat as quick replies. Adding in the message object a `suggestions` field with the value an array of strings will trigger this functionality

```javascript
{
  author: 'support',
  type: 'text',
  id: 1, // or text '1'
  data: {
    text: 'some text',
    meta: '06-16-2019 12:43'
  },
  suggestions: ['some quick reply', ..., 'another one']
}
```


#### Html Message

Add `isHtml` property to show HTML content in a text message

```json
{
   "type":"text",
   "author":"`me`",
   "id":22,
   "data":{
      "text":"<b>HTML Content</b><ul><li>item 1</li><li>item 2</li></ul>",
      "isHtml":true
   }
}
```

#### Customized Action

You could define your handling logic from the payload data
data:
```json
{
   "type":"action",
   "author":"`support`",
   "id":23,
   "data":{
      "text":"Show Alert",
      "payload":{
         "prop1":"prop1",
         "prop2":"Hello World from support"
      }
   }
}
``` 

 In your vue:
 ```javascript
 //template
 ...
 <beautiful-chat
      ...props
      @action="onAction"
    >
....
//script
...
methods: {
	onAction($event){
		//write your logic here
		console.log($event.prop1);
	    alert($event.prop2);
	}
}
....
 ```

- Fix/add your changes
- `yarn build` on the root to have the library compiled with your latest changes
- create a pull request describing what you did
- discuss the changes with the maintainer
- boom! your changes are added to the main repo

</details>

<details><summary>How can I customize the colors?</summary>
<p>

- When initializing the component, pass an object specifying the colors used:

```javascript
let redColors = {
  header: {
    bg: '#D32F2F',
    text: '#fff'
  },
  launcher: {
    bg: '#D32F2F'
  },
  messageList: {
    bg: '#fff'
  },
  sentMessage: {
    bg: '#F44336',
    text: '#fff'
  },
  receivedMessage: {
    bg: '#eaeaea',
    text: '#222222'
  },
  userInput: {
    bg: '#fff',
    text: '#212121'
  }
}
```

```vue
<beautiful-chat
  ...
  :colors="redColors" />
```

This is the red variant. Please check [this file](https://github.com/mattmezza/vue-beautiful-chat/tree/master/demo/src/colors.js) for the list of variants shown in the demo page online.

Please note that you need to pass an Object containing each one of the color properties otherwise the validation will fail.

</p>
</details>
<details><summary>How can I add message formatting?</summary>
<p>

Good news, message formatting is already added for you. You can enable it by setting `messageStyling` to `true` and you will be using the [msgdown](https://github.com/mattmezza/msgdown) library. You can enable/disable the formatting support at any time, or you can let users do it whenever they prefer.
