React Live Chat Loader

An npm module that allows you to mitigate the negative performance and user experience impact of chat tools. react-live-chat-loader shows a fake widget until the page has become idle or users are ready to interact with chat. Currently works with Intercom and Help Scout.

How it works

Chat widgets rely heavily on JavaScript which comes at a cost. Given the significant impact that comes from the download, parse, compile and execution of chat JavaScript, React Live Chat Loader implements a "fake", fast loading button and waits for one of the following events before loading the actual widget:

User hovers over the fake button
User clicks the fake button
The page has been idle for a significant amount of time

Under the hood React Live Chat Loader makes use of requestIdleCallback to track how long the page has been idle for and checks if the user is on a slow connection (using navigator.connection.effectiveType) or has data-saver enabled (using navigator.connection.saveData) to prevent loading.

Installation

To download react-live-chat-loader run:

npm install --save react-live-chat-loader

Or if you're using yarn, run:

yarn add react-live-chat-loader

Usage

To allow you to trigger a single live chat within your application, React Live Chat Loader has a Context Provider which should be added at the root level of your application.

You pass your providerKey and provider to the LiveChatLoaderProvider.

For example, to add a LiveChatLoaderProvider for Help Scout you would do the following:

import { LiveChatLoaderProvider } from 'react-live-chat-loader'

export default class App extends React.Component {
  /* ... */

  render() {
    return (
      <LiveChatLoaderProvider providerKey="asdjkasl123123" provider="helpScout">
        /* ... */
      </LiveChatLoaderProvider>
    )
  }
}

You can then include the relevant chat where you would like it to appear.

For example, for Help Scout you would import the HelpScout component and add it to your application:

import { HelpScout } from 'react-live-chat-loader'

export default class Index extends React.Component {
  /* ... */

  render() {
    return (
      <>
        /* ... */
        <HelpScout />
      </>
    )
  }
}

To display chat from a custom button you can import the useChat hook which has the current state of the chat and a function to load the chat.

import { useChat } from 'react-live-chat-loader'

export const LoadChatButton = () => {
  const [state, loadChat] = useChat()

  return <button onClick={loadChat}>Load Chat</button>
}

Options

You can pass the following props to the LiveChatLoaderProvider provider:

provider: Choose from helpScout or intercom (see below)
providerKey: Provider API Key (see below)
idlePeriod: How long to wait in ms before loading the provider. Default is 2000. Set to 0 to never load. This value is used in a setTimeout in browsers that don't support requestIdleCallback.

Supported Providers

Currently there are two supported providers:

Help Scout

To use Help Scout import the LiveChatLoaderProvider and set the provider prop as helpScout and the providerKey prop as your Beacon API Key.

Then import the HelpScout component.

import { LiveChatLoaderProvider, HelpScout } from 'react-live-chat-loader'

export default class App extends React.Component {
  render() {
    return (
      <LiveChatLoaderProvider providerKey="asdjkasl123123" provider="helpScout">
        /* ... */
        <HelpScout />
      </LiveChatLoaderProvider>
    )
  }
}

You can customise the Help Scout beacon by passing the following props to the HelpScout component:

color: The background color of the beacon
icon: Choose from message, antenna, search, question, beacon
zIndex: Changes the CSS index value of how the Beacon relates to other objects
horizontalPosition: Choose from left or right

Currently the Help Scout component only supports the icon button style.

Intercom

To use Intercom import the LiveChatLoaderProvider and set the provider prop as intercom and the providerKey prop as your Intercom App ID.

Then import the Intercom component.

import { LiveChatLoaderProvider, Intercom } from 'react-live-chat-loader'

export default class App extends React.Component {
  render() {
    return (
      <LiveChatLoaderProvider providerKey="asd239" provider="intercom">
        /* ... */
        <Intercom />
      </LiveChatLoaderProvider>
    )
  }
}

You can customise the color of the Intercom widget by passing a color prop to the Intercom component.

Adding a provider

To contribute a new provider, follow these steps:

1. Create provider file

Create a new provider file at src/providers/providerName.js using the following as a template:

Provider Template

const domain = 'https://provider.domain.com'

const loadScript = () => {
  // Detect the provider is already loaded and return early
  if (alreadyLoaded) return

  // Call provider script here
}

const load = ({ providerKey }) => {
  loadScript()
  // Initialise provider script
}

const open = () => // Open provider
const close = () => // Close provider

export default {
  domain,
  load,
  open,
  close
}

The provider must export the following:

domain: A string of the domain where the provider script is loaded from that will be used in a preconnect link.
load: Function which when called will load and initialize the provider script. It should accept props and use the providerKey as the app_id or api_key. For consistency, it should call a loadScript function.
open: Function which when called will open the provider chat.
close: Function which when called will close the provider chat.

Import the new file in src/providers/index.js and add it to Providers.

The name of this file will be the providerKey used in the LiveChatLoaderProvider.

2. Create component

Create a new component in src/Components/ProviderName/index.js which replicates the chat widget, using the following as a template:

Component Template

import React from 'react'

import { useChat } from '../../'
import STATES from '../../utils/states'

const styles = {
  // Add widget styles here
  button: {
    // Add button styles here
  }
}

const Provider = ({ color }) => {
  const [state, loadChat] = useChat({ loadWhenIdle: true })

  if (state === STATES.COMPLETE) return null

  return (
    <div>
      <button
        onClick={() => loadChat({ open: true })}
        onMouseEnter={() => loadChat({ open: false })}
        style={{
          ...styles.button,
          backgroundColor: color
        }}
      >
        Button
      </button>
    </div>
  )
}

Provider.defaultProps = {
  color: '#976ad4'
}

export default Provider

Do not worry about loading animations as the widget will be shown instantly on page load. Increase the z-index by 1 so the fake widget sits immediately above the chat widget that is being replaced.

Export the component from src/index.js

3. Update README

Add your new provider to this README under Supported Providers.
