Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

CXCO CORE

The CORE is a package that provides common functionalities to the VA implementations.

  • Default exposed javascript API.
  • Utilities (Markdown parser, etc)

Config

The configuration object is a JSON object that should be available the moment the core loads:

window.cxcoConfig = {
        project: {
            publicApiKey: 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx',
            culture: 'en',
            customerKey: 'customerA',
            key: 'projectB'
        },
        dci: {
            /* check the documentation for the complete ci configuration */
        }
    };

Some of the configuration parameters are stored in the sessionStorage under 'cxco.dci' as part of the initial state that will define how the DCI will load.

Global Options root of the configuration object

|option| optional| description| example| |---|---|---|---| |engineUrl | optional | Specifies which base url to use | 'https://proxy.domain.com/customerA/projects/projectB' | |lazyLoad| optional | Defines how the DCI initializes. Defaults to false | true | |session| optional | Sets Session variables | { mode: 'test' }|

Project Options window.cxcoConfig.project

|option| optional| description| example| |---|---|---|---| |publicApiKey | mandatory | the given API Key| 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx' | |culture | mandatory | language country code | 'en' | |customerKey | mandatory | the given customer key | 'customerA' | |key | mandatory | the given project key | 'projectB' |

Options

const instance = new CxcoCore({ useWindowConfig: true, useWindowApi: true, component: 'dci' })

|Option|type|description| |---|---|---| |useWindowConfig|boolean|Get options from window.cxcoConfig| |useWindowApi|boolean|Listen to events from window.cxco| |component|string|Component name|

When the option useWindowApi is true the core can be use from the browser's window object.

You can then trigger actions such as:

  • sendEvent
  • ask
  • answer
  • on
  • changeState
  • transcript
  • archive

Examples

// 1 - add metadata to ask request

cxco.push([
        'on',
        'ask',
        function (result) {
            console.log('ask received on the window listener', result)

            if (result.metadata.dimensions) {
                result.metadata.dimensions.push({ 'LoggedIn': 'true' })
            } else {
                result.metadata.dimensions = [{ 'LoggedIn': 'true' }]
            }

        }
    ]);   

// 2 -modify or replace an answer
cxco.push([
        'on',
        'answer',
        function (result) {
            console.log('answer received on the window listener', result)
            result.data.answer = '<p>Modified Answer</p>'
        }
    ])

// 3 - hide input field
cxco.push(['showInput', false])

// 4 - send and event
cxco.push(['sendEvent', 'event_name'])

// 4b - send event with extra metadata
cxco.push(['sendEvent', { data: { eventName: 'event_name'} , metadata: { session: { mode: 'internal'} } }])

/** 5 - Change State of the chatbot.
* modifiable properties: 
* - 'isHidden' (boolean)
* - 'isOpen'(boolean) 
*/
cxco.push(['changeState', { isHidden: true }])

// 6 - trigger a question.
cxco.push(['ask', 'hello world!'])

// 6b - trigger a question passing additional metadata.
cxco.push(['ask', { data: { userInput: 'hello world!'} , metadata: { session: { firstName: 'Joe'} } }])	

// 7 - adding a question message bubble bypassing DCX.
cxco.push(['ask', { data: { userInput: 'hello world!'} , metadata: { target: 'ui' } }])	

// 7b - asking a question in DCX message bubble bypassing the UI.
cxco.push(['ask', { data: { userInput: 'hello world!'} , metadata: { target: 'api' } }])	

// 8 - adding an answer message bubble bypassing DCX.
cxco.push(['answer', { data: { answer: 'The quick brown fox\n\njumps over the lazy dog.'}}])

Plugins

The core allows to register plugins that will listen to core events.

import CxcoCore from '@cxco/core'
import cxcoChatWidget, { htmlAnswers } from '@cxco/ui-chat'
import cxcoDcxApi from '@cxco/api-dcx'

const elm = document.createElement('div')

const instance = new CxcoCore({ useWindowConfig: true, useWindowApi: true })

instance.use(htmlAnswers)
instance.use(cxcoChatWidget(elm))
instance.use(cxcoDcxApi({}))

The plugin package must expose a install function that accepts the core as an argument. In that function you can bind your functions to core events.

// plugin example
export default function (elm) {
    // ...
    return {
        install (core) {

            const chatApp = app(state, actions, view, elm)

            core.on('answer', chatApp.onAnswer)

            core.on('ui.showInput', chatApp.showInput)
        }
    }
}

The Core Answer Object

The core answers with an JSON object that has two main properties: data and metadata.

The data property contains the information that can be show to the user. The metadata contains the extra information that among other things can be used to adapt the GUI.

An example answer would look like:

{
    "data": {
        "type": "answer",
        "answer": "The answer\n",
        "images": [],
        "videos": [],
        "outputAdditions": {},
        "links": []
    },
    "metadata": {
        "sessionId": "257f9ad8-7885-4ffc-99e9-41dc3a6d5014",
        "interactionId": "ba51d5b8-461c-4ea9-acec-72195d810391",
        "culture": "en",
        "escalation": "escalation_1x_noanswer",
        "relatedFaqs": [
            {
                "id": 289,
                "question": "Which are the best pizzas in town?",
                "categories": [
                    1,
                    33
                ]
            },
            {
                "id": 257,
                "question": "Which are the best burgers in town?",
                "categories": [
                    1,
                    98
                ]
            }
        ],
        "originalRequest": {
            "config": {
            },
            "data": {
                "userInput": "I want to eat."
            },
            "metadata": {
                "minFaqs": 1,
                "maxFaqs": 3,
                "classificationId": 1,
                "sessionId": "257f9ad8-7885-4ffc-99e9-41dc3a6d5014",
                "dimensions": [
                    {
                        "LoggedIn": "false"
                    }
                ]
            }
        }
    }
}

In this particular payload there are some contextual FAQs in metadata.relatedFaqs so, the GUI could use them to present more options to the user. It also contains a metadata.escalation stating that the engine couldn't recognize the question.
