NPM

Import the package

npm i @daniel-ordonez/vue-chatui

Register the component in Vue

import { VueChatui } from '@daniel-ordonez/vue-chatui';
export default{
	components:{
    	VueChatui
    }
}

Use the component tag

<template>
	<vue-chatui></vue-chatui>
</template>

Usage

To access your component easily use the ref attribute

<vue-chatui ref="chat"></vue-chatui>

Then assign it to a variable

// 'this' is your Vue instance
let {chat} = this.$refs;

Adding text programatically

//Passing a plain string will add a new text bubble at the left
chat.addEntry("Bot says hello!");
//You can pass an object with the property 'user:true' to add the bubble at the right
chat.addEntry( { text : "User says hi!", user : true } );

The function addEntry accepts either a string or an object with the following structure:

If it's given a string, the rest attributes will set to defult { user: false, loading: true, loadingTimeout: 500 }

The addEntry function returns a new object with the same attributes plus a new one

User input text

//This enables a textarea for the user
chat.userInput("text");

When the user submits (by pressing the send button), the text is put into an object (data) and addEntry is called

/*
data = {
 text: <whatever the user typed>,
 user: true,
 loading: false
}
*/
addEntry(data);

All that is made under the hood, userInput returns a Promise that resolves after the new chat bubble with the user text is readable.

Using with async/await

async talk = (chat) => {
  //Use the readable promise
  await chat.addEntry("What's your name?").readable;
  let name = await chat.userInput("text");
  //userInput returns an object after the user submits a response
  await chat.addEntry(`Nice to meet you ${name.text}`).readable;
  console.log("done");
}

If you want to only capture the user's input without adding a new entry, use getUserInput

async talk = (chat) => {
  await chat.addEntry("Tell me a secret").readable;
  let secret = await chat.getUserInput();
  //storeSecure( secret.text );
  await chat.addEntry("Your secret is safe with me").readable;
  console.log("done");
}

It works the same as userInput but the Promise resolves right after the user submits returning the object

{
 text: <whatever the user typed>,
 user: true,
 loading: false
}
