Webchat components
In this section, we will see the most relevant webchat components that have been used to create this example.
1. Cover Component
The Cover Component is the first component that will appear when a user opens the webchat.
We have used styled-components that allows us to define new React component with our styles attached to it.
src/webchat/cover-component.js
import styled from 'styled-components'
const Container = styled.div`
position: absolute;
height: 432px;
width: calc(100%-60px);
left: 0;
top: 48px;
background: white;
display: flex;
flex-direction: column;
justify-content: center;
align-items: center;
padding: 0px 30px 20px 30px;
z-index: 3;
`
const Button = styled.button`
width: 80px;
height: 40px;
background: #2f2f2f;
border-radius: 8px;
margin-top: 20px;
text-align: center;
color: white;
`
const Text = styled.a`
position: relative;
fontfamily: Verdana;
fontweight: normal;
fontsize: 14px;
text-align: center;
width: 85%;
line-height: 1.4;
color: #000000;
margin: 0px 30px 20px 30px;
`We have also used the TextField component from material-ui to let the users enter and edit text.
import TextField from '@material-ui/core/TextField'
export function MyTextField(props) {
let helperText = ''
if (props.error)
helperText =
props.error && props.value === ''
? 'This field is required'
: props.errorMessage || ''
return (
<TextField
variant='filled'
{...props.params}
required={props.required}
label={props.label}
value={props.value}
onChange={props.onChange}
error={helperText !== ''}
helperText={helperText}
disabled={props.disabled}
style={props.style || { width: '80%', margin: '5px' }}
/>
)
}After defining these components, we have created our CustomCover component as:
export default class CustomCover extends React.Component {
static contextType = WebchatContext
constructor(props) {
super(props)
this.state = {
name: '',
email: '',
error: false,
}
}
close() {
if (this.verifiedForm()) {
this.context.updateUser({
name: this.state.name,
extra_data: { email: this.state.email, hotels: [] },
})
this.context.sendText('Start', 'PAYLOAD')
this.props.closeComponent()
} else {
this.setState({ error: true })
}
}
verifiedForm() {
if (!this.incorrectName() && !this.incorrectEmail()) {
return true
}
return false
}
incorrectName() {
return this.state.name == ''
}
incorrectEmail() {
return !this.state.email.match(emailRegex) || this.state.email == ''
}
handleName = event => {
this.setState({ name: event.target.value })
}
handleEmail = event => {
this.setState({ email: event.target.value })
this.setState({ error: false })
}
render() {
return (
<Container>
<Text>
Welcome to Botonic Booking Platform First of all, I would need your
name and email.
</Text>
<MyTextField
required={true}
label='Name'
onChange={this.handleName}
value={this.state.name}
error={this.state.error && this.incorrectName()}
/>
<MyTextField
required={true}
label='Email'
onChange={this.handleEmail}
value={this.state.email}
error={this.state.error && this.incorrectEmail()}
errorMessage={'Please use a valid Email format'}
/>
<Button onClick={() => this.close()}>START</Button>
<p style={{ fontSize: 10 }}>
<em>
We will not store the fulfilled information. You can fake the data.
</em>
</p>
</Container>
)
}
}We have created some functions to check and handle the user data. Moreover, to store the relevant information in the session we have used the updateUser() function.
Finally, to close the component, we have called the closeComponent() function that can be found in the props. In this case, we also used sendText to add a message form the user after the component is closed. That then will be captured in the routes and will execute the next action.
src/routes.js
{ path: 'start', text: /^start$/i, action: Start },After creating our component we just need to assign it to the coverComponent property:
src/webchat/index.js
import CustomCover from './cover-component'
export const webchat = {
coverComponent: CustomCover,
}2. Custom Messages
Custom Messages allows us to create any kind of message that we want.
2.1 Custom Message from bot
We have used a CustomMessage to create the Hotel Form that appears after the user chooses the hotel to book.
In this component, we have also used styled-components and material-ui to create the TextField, the Autocomplete and the DatePicker components.
The structure is very similar to the CustomCover component, but in this case we need to export the component as:
src/webchat/hotel-form-message.js
export default customMessage({
name: 'hotel-form',
component: HotelForm,
defaultProps: {
style: {
width: '100%',
backgroundColor: '#ffffff',
border: 'none',
boxShadow: 'none',
paddingLeft: '5px',
},
imageStyle: { display: 'none' },
blob: false,
enableTimestamps: false,
},
})The name and component props are mandatory, and in this case, we have also defined the defaultProps to change some properties of the message.
The last important step to do when we define a CustomMessage, is to add it in the custom types:
src/webchat/index.js
import HotelForm from './hotel-form-message'
export const webchat = {
theme: {
message: {
customTypes: [HotelForm, RateMessage, RateUserMessage],
},
},
}Then we can call this component in the actions.
src/actions/book-hotel.jsx
import React from 'react'
import { Text } from '@botonic/react'
import HotelForm from '../webchat/hotel-form-message'
export default class extends React.Component {
static async botonicInit(request) {
const hotel = request.input.payload.split('-')[1]
const name = request.session.user.name
return { hotel, name }
}
render() {
return (
<>
<Text>
{this.props.name} you have selected **{this.props.hotel}**. To confirm
the reservation, we would need some more information.
</Text>
<HotelForm hotel={this.props.hotel} />
</>
)
}
}2.2 Custom Message from user
It is also possible to add a custom message on the user side, as we have done with RateUserMessage.
In this case, we have used react-stars to display the rate of the user. To add this message on the user side the only extra thing we need to do is change the from property to 'user'.
src/webchat/rate-user-message.js
import React from 'react'
import { customMessage, WebchatContext } from '@botonic/react'
import ReactStars from 'react-stars'
class RateUserMessage extends React.Component {
static contextType = WebchatContext
render() {
return (
<ReactStars
count={5}
size={24}
value={parseFloat(this.props.rate)}
edit={false}
color2={'#ffffff'}
/>
)
}
}
export default customMessage({
name: 'rate-user-message',
component: RateUserMessage,
defaultProps: {
from: 'user',
},
})3. Persistent Menu
The Persistent Menu is a component that will be shown whenever the user clicks to the button placed in the bottom left corner.
src/webchat/index.js
import CheckReservationsWebview from '../webviews/components/check-reservations'
import { CustomPersistentMenu } from './custom-persistentMenu'
export const webchat = {
theme: {
userInput: {
persistentMenu: [
{ label: 'Check your reservation', webview: CheckReservationsWebview },
{ label: 'Book a hotel', payload: 'carousel' },
{ closeLabel: 'Close' },
],
menu: {
darkBackground: true,
custom: CustomPersistentMenu,
},
},
},
}In this case, we have created a persistentMenu with three buttons: the first one will open a webview, the second one will send the payload 'carousel' and the last one will close the menu.
In this example, we have also customized our menu in custom-persistentMenu.js and we have enabled the darkBackgroud property to darken the background of the webchat and let the user focus on the persistent menu only.
Carousel
The Carousel component allows you to show a collection of images in a cyclic view. In the example, we have used it to show the different hotel options.
src/actions/carousel.js
import React from 'react'
import {
Text,
Carousel,
Element,
Pic,
Button,
Title,
Subtitle,
} from '@botonic/react'
export default class extends React.Component {
render() {
const hotels = [
{
name: 'Hotel Alabama',
desc: '* * * *',
payload: 'hotel-Hotel Alabama',
pic:
'https://cdn.styleblueprint.com/wp-content/uploads/2017/06/4512594599_9edc8fee0a_b.jpg',
},
{
name: 'Hotel Arizona',
desc: '* * * * *',
payload: 'hotel-Hotel Arizona',
pic:
'https://images.trvl-media.com/hotels/10000000/9760000/9754700/9754671/88c37982_z.jpg',
},
{
name: 'Hotel California',
desc: '* *',
payload: 'hotel-Hotel California',
pic:
'https://estaticos.elperiodico.com/resources/jpg/4/0/hotel-california-todos-santos-baja-california-1493803840904.jpg',
},
]
return (
<>
<Text>Select an hotel among these options:</Text>
<Carousel>
{hotels.map((e, i) => (
<Element key={e.name}>
<Pic src={e.pic} />
<Title>{e.name}</Title>
<Subtitle>{e.desc}</Subtitle>
<Button payload={e.payload}>Book</Button>
</Element>
))}
</Carousel>
</>
)
}
}Webviews
Webviews allow us to open standard webpages during a chat conversation. In this example, we have used it to create a webpage where the user can check the hotel reservations. As we have mentioned before we can open it using the persistentMenu or with one of the button in the Start action.
src/actions/start.jsx
import React, { useEffect } from 'react'
import { Text, Button } from '@botonic/react'
import CheckReservationsWebview from '../webviews/components/check-reservations'
export default class extends React.Component {
static async botonicInit(request) {
const name = request.session.user.name
return { name }
}
render() {
return (
<>
<Text>
Hi {this.props.name}, Im your virtual assistant of Botonic Booking
Platform. I will help you manage your hotel reservations and much
more.
</Text>
<Text>
Select an option:
<Button payload='carousel'>Book a hotel</Button>
<Button webview={CheckReservationsWebview}>
Check your reservations
</Button>
</Text>
</>
)
}
}In this case, we have also used styled-components and the TextFiled.
src/webviews/components/check-reservations.js
render() {
this.state.hotels = this.getHotels(this.context)
this.state.correctName = this.getName(this.context)
this.state.correctEmail = this.getEmail(this.context)
const InfoDatos = (props) => {
return (
<>
<hr
style={{
width: '85%',
height: '1px',
border: 'none',
color: '#D6D6D6',
backgroundColor: '#D6D6D6',
}}
/>
<Text>{props.hotel}</Text>
<Text
style={{
color: '#495e86',
marginBottom: '0px',
}}
>
<a>
Name: {this.state.correctName}
<br />
Guests: {props.guests}
<br />
Date: {props.date}
</a>
<br />
<a>Email: </a>
<a href={`mailto:${this.context.correctEmail}`}>
{this.state.correctEmail}
</a>
<br />
<a>Phone: </a>
<a href={`tel:${props.phone}`}>{props.phone}</a>
<br />
<br />
</Text>
</>
)
}
return (
<Form>
{this.state.identified ? (
<>
<h2>Your reservation</h2>
{this.state.hotels.map((h, i) => (
<InfoDatos key={i} {...h} />
))}
<Button onClick={() => this.close()}>CLOSE</Button>
</>
) : (
<>
<Text
style={{
margin: '20px 0px 20px 22px',
}}
>
To check your reservation, enter your name and email.
</Text>
<MyTextField
required={true}
label='Name'
onChange={this.handleName}
value={this.state.name}
error={this.state.errorName}
errorMessage={'The name does not match'}
/>
<MyTextField
required={true}
label='Email'
onChange={this.handleEmail}
value={this.state.email}
error={this.state.errorEmail}
errorMessage={'The email does not match'}
/>
<Button onClick={() => this.singIn()}>LOGIN</Button>
</>
)}
</Form>
)
}In order to continue with the conversation flow, we call the closeWebview function which closes the webview and sends a payload:
close() {
this.context.closeWebview({
payload: 'close-webview',
})
}The last step, is to add the new webview in the index:
src/webviews/index.js
import WebviewReserva from './components/check-reservations'
export const webviews = [WebviewReserva]...and we are done 🎉
