Vue Chat Bot

For the one who is finding a customizable chatbot UI.

I build for my private project, but I tried to bring as many options as I think someone need it, so feel free to use it.

Install

npm i vue-chat-bot

// or

yarn add vue-chat-bot

Usage

Import & register the component

import { VueChatBot } from 'vue-chat-bot'

export default {
  components: {
    VueChatBot,
  },
  ...
}

And use it:

<VueChatBot
  :messages="data"
  :options="botOptions"
  @msg-send="messageSendHandler"
/>

data () {
  return {
    data: [], // See Data example below
    botOptions: {
      // See the list of options below
    }
  }
}

Components & Events

This is the most important part you need to know, because you need these to integrate your bot API. Take a look my App.vue file if you need an example.

Events

Name	Params	Description
init		Fire the first time the board is opened
open		Fire everytime the board is opened
msg-send	value (Object)	Fire when user hit Send or select an option
destroy		Fire when board is closed

Use msg-send to get the message from user and trigger request to bot API.

Components

Common pattern / Example data:

const messages = [
  {
    agent: 'bot', // Required. 'bot' or 'user'
    type: 'text', // Required. Bubble message component type: 'text' / 'button'
    text: 'Hello. How can I help you', // Required. The message
    disableInput: false, // Disable message input or not
    ...
  },
  {
    agent: 'user',
    type: 'text', // always
    text: 'I need a new laptop',
  },
  ...
]
