BoCode-AppChat-React

An AppChat API library useful as interface for your React application.

Installation

Install the component in your project:

npm i bocode-chatbot-react --save

Usage

Import the component into your project:

import { AppChatProvider } from 'bocode-chatbot-react';

Use the component AppChatProvider as parent of your application as below:

<AppChatProvider>
    <YourComponentApp/>
</AppChatProvider>

Example-App

Let's go to define your component <YourComponentApp/> :

Import the AppChat UI and AppChatContext components:

import { AppChat, AppChatContext } from 'bocode-chatbot-react';

Define the AppChat context in this way:

 const { appchat } = useContext(AppChatContext);

It's possibile to create a custom InputDevice as the following InputNumberDevice:

export const InputNumberDevice: React.FC<InputInterfaceProps> = props => {

  const { value, onOutput, onEnterPressed, onError } = props;
  const [errorMessage, setErrorMessage] = useState('');

  const handleChange = useCallback((e: ChangeEvent<HTMLInputElement>) => {
    const val = e.target.value;
    const isError = Number(val) < 0 ? true : false;
    const updatedValidationStatus = {
      canSend: true,
      isError: false,
      message: '',
    };

    if (isError) {
      updatedValidationStatus.isError = true;
      updatedValidationStatus.message = 'The value ' + val + ' must be greater or equal of zero';
      setErrorMessage(updatedValidationStatus.message);
      onError(updatedValidationStatus);
      onOutput([val, val]);
    }
    else {
      setErrorMessage('')
      onError(updatedValidationStatus);
      onOutput([val, val]);
    }

  }, [onOutput, onError]);

  const handleEnter = useCallback((e: React.KeyboardEvent<HTMLInputElement>) => {

    if (e.key === 'Enter') {
      e.preventDefault();
      onEnterPressed();
    }

  }, [onEnterPressed]);

  return (
    <div css={styles['input-device']}>
      <input type="number" name="input" onKeyDown={handleEnter} value={value} onChange={handleChange} />
      <label className='name'>Number</label>
      <p className='error'>{errorMessage}</p>
    </div>
  );
};

Use the following API methods to interface with the AppChat:

    appchat.say('Hello World');
    appchat.question('What is your name ?').ask();
    appchat.question('Question with YesNo').yesNo().ask();
    appchat.question('Question with YesNo').yesNoCancel().ask();
    appchat.question('What is your favourite color ?').withOptions(options).singleChoice().ask();
    appchat.question('What is your favourite color ?').withOptions(options).multipleChoice().ask();
    appchat.question('How old are you ?').with(InputNumberDevice).ask();

      .yesNoCancel()
      .ask();
