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.

{
  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

{
  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

How to get the demo working?

  • cd vue-beautiful-chat
  • yarn watch # this starts the compiler so everytime you edit files they get compiled
  • cd demo
  • yarn dev # this starts a web server on localhost:8080 so the demo shows up - it also watches for the demo files changes

How can I add a feature or fix a bug?

  • 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 😉

How can I customize the colors?

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

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'
  }
}

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

This is the red variant. Please check this file 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.

How can I add message formatting?

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 library. You can enable/disable the formatting support at any time, or you can let users do it whenever they prefer.
