## Components

# Launcher

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

Launcher props:

|      prop        | type   | required | description |
|------------------|--------|----------|-------------|
| agentProfile     | [object](#agent-profile-objects) | yes | Represents your product or service's customer service agent. Fields: imageUrl (string), teamName (string). |
| onClick          | function | yes | Intercept the click event on the launcher. No argument sent when function is called. |
| isOpen           | boolean | yes | Force the open/close state of the chat window. If this is not set, it will open and close when clicked. |
| messageList      | [[message](#message-objects)] | yes | An array of message objects to be rendered as a conversation. |
| mute             | boolean | no | Don't play sound for incoming messages. Defaults to `false`. |
| newMessagesCount | number | no | The number of new messages. If greater than 0, this number will be displayed in a badge on the launcher. Defaults to `0`. |
| onFilesSelected  | function([fileList](https://developer.mozilla.org/en-US/docs/Web/API/FileList)) | no | Called after file has been selected from dialogue in chat window. |
| onMessageWasSent | function([message](#message-objects)) | yes | Called when a message is sent, with a message object as an argument. |
| showEmoji        | boolean | no | Whether or not to show the emoji button in the input bar. Defaults to `true`.
| fileUpload       | boolean | no | 
| pinMessage       | object  | no | 
| placeholder      | string  | no | 


### Message Objects

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

``` javascript
{
  author: 'them',
  type: 'text',
  data: {
    text: 'some text'
  }
}

{
  author: 'me',
  type: 'emoji',
  data: {
    code: 'someCode'
  }
}


{
  author: 'me',
  type: 'file',
  data: {
    url: 'somefile.mp3',
    fileName: 'Any old name'
  }
}

```

### Agent Profile Objects

Look like this:

```js
{
  imageUrl: 'https://somewhere.on/the_web.png',
  teamName: 'Da best'
}
```
