## 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.

#### Props

|prop | type   | description |
|-----|--------|---------------|
| *participants | [agentProfile] | Represents your product or service's customer service agents. Fields for each agent: id, name, imageUrl|
| *onMessageWasSent | function(message) | Called when a message is sent with the message object as an argument. |
| *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
| showTypingIndicator | String | A string that can be set to a user's participant.id to show `typing` indicator for them
| showHeader | Boolean | A bool indicating whether or not to show the header of chatwindow
| disableUserListToggle | Boolean | A bool indicating whether or not to allow the user to toggle between message list and participants list
| colors | Object | An object containing the specs of the colors used to paint the component. [See here](#faq)
| messageStyling | Boolean | A bool indicating whether or not to enable `msgdown` support for message formatting in chat. [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']
}
```

### FAQ

<details><summary>How to get the demo working?</summary>
<p>

```
git clone git@github.com:mattmezza/vue-beautiful-chat.git
cd vue-beautiful-chat
yarn install  # this installs the package dependencies
yarn watch  # this watches files to continuously compile them
```

Open a new shell in the same folder

yarn dev # this starts the dev server at http://localhost:8080
```

<details><summary>How can I add a feature or fix a bug?</summary>
<p>

- Fork the repository
- 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
- a release is created almost once per week 😉

</p>
</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.
