How to Build Chatbot with React Native – A Step-by-Step Tutorial

Here's a step-by-step guide on how to use React Chatbot Kit in your React application:

1. Install React Chatbot Kit:

npm install react-chatbot-kit

2. Import the necessary dependencies:

import Chatbot from 'react-chatbot-kit';

import 'react-chatbot-kit/build/main.css';

3. Create the necessary files:

The chatbot requires three dependencies in order to function. Create a directory in your project to keep the files related to the chatbot and create the following three files:

MessageParser.js

ActionProvider.js

config.js

4. Initialize the chatbot:

In the component where you want to display the Chatbot, initialize the Chatbot in the following way:

class MyChatBot extends React.Component {

render() {

return (

<div>

<Chatbot

messageParser={MessageParser}

actionProvider={ActionProvider}

config={config}

/>

</div>

);

}

}

This will create a new instance of the Chatbot and render it in your React application.

5. Provide a message parser:

The message parser is responsible for processing user input and extracting entities from the user's message. Create a MessageParser.js file and implement the parseMessage() method. This method should take a user message as input and return an object containing the extracted entities.

6. Provide an action provider:

The action provider is responsible for taking an action based on the user's message. Create an ActionProvider.js file and implement the handleAction() method. This method should take an action object as input and perform the necessary action.

7. Configure the chatbot:

Create a config.js file and export an object with the following properties:

export default {

initialMessage: 'Hello there!',

botAvatar: 'https://example.com/bot-avatar.png',

userAvatar: 'https://example.com/user-avatar.png',

};

This will configure the chatbot with the initial message, bot avatar, and user avatar.

With these steps, you have successfully initialized the React Chatbot Kit in your React application and can start building your chatbot. You can extend the chatbot by creating custom components, hooks, and tools to fit your specific needs.

Creating a call app in React Native involves several steps, including setting up the project, implementing calling functionalities, and integrating with the device's calling system. Here's a general overview of the process:

1. Project Setup:

• Install React Native and its dependencies:
• Bash

npm install -g react-native

• Create a new React Native project:

• Bash

npx react-native init CallApp

2. Calling Functionalities:

• Install the react-native-phone-call library:

• Bash

npm install react-native-phone-call

• Import the library and use its methods to initiate calls:

• JavaScript

import PhoneCall from 'react-native-phone-call';

const handleCall = () => {

  const phoneNumber = '1234567890';

  const args = {

    number: phoneNumber,

    prompt: true,

  };

  PhoneCall.call(args).catch(console.error);

};

3. Device Integration:

• Request permissions to access the device's calling system:

• JavaScript

import { Platform } from 'react-native';

import Permissions from 'react-native-permissions';

const requestCallPermission = async () => {

  if (Platform.OS === 'android') {

    const granted = await Permissions.askAsync(Permissions.PERMISSIONS.ANDROID.CALL_PHONE);

    if (!granted.granted) {

      alert('Call permission denied!');

    }

  }

};

• Handle incoming calls and manage call states:
• JavaScript

import CallManager from '@react-native-community/call-keep';

CallManager.startCallAudio();

CallManager.answerCall();

CallManager.endCall();

4. User Interface:

• Create a user interface that allows users to input phone numbers and initiate calls:
• JavaScript

import React, { useState } from 'react';

import { View, TextInput, Button } from 'react-native';

const CallScreen = () => {

  const [phoneNumber, setPhoneNumber] = useState('');

  const handleCall = () => {

    // Implement calling functionality using PhoneCall library

  };

  return (

    <View>

      <TextInput

        value={phoneNumber}

        onChangeText={setPhoneNumber}

        placeholder="Enter phone number"

      />

      <Button title="Call" onPress={handleCall} />

    </View>

  );

};

Remember to test your call app thoroughly to ensure it works as expected and handles different scenarios, such as incoming calls, call states, and error handling.

Creating your own AI chatbot is a simple 4 step process. For this, you will need a Kommunicate account and 10 minutes of your time.

To create your own AI chatbot:

1. Sign up to Kommunicate.
2. Navigate to the ‘Bot Integration‘ section on the left panel of the dashboard and click on Kompose. Use Flow Designer to visualize and design the flow of chat conversations.
3. Copy the Javascript code from the install section under Settings and paste it above the closing body tag on the page where you want the chat widget to appear.
4. Go to Conversation Rules enable assign new conversations to the bot and select your newly configured bot from the dropdown.
