React Chatbox Component with Animations

This code snippet implements a chatbox component using React with features like message history, user input, and animated bot responses. Let's break down the code and understand its functionalities.

Imports:

The code imports necessary libraries from React:

• useState for managing component state.
• AnimatePresence and motion from react-motion for animations.

ChatBox Component:

The ChatBox component is the main functional component responsible for rendering the chatbox UI and handling interactions.

State Variables:

• inputValue: Stores the current user input text.
• disableForBot: Controls the disabled state of the input field during bot responses.
• messages: An array of objects representing chat messages, including text and sender ("user" or "bot").
• isTyping: A boolean flag indicating if the bot is currently "typing" (simulated animation).

Message Handling:

• handleInputChange: This function updates the inputValue state variable whenever the user types in the input field. It also triggers a temporary isTyping state to simulate bot activity.

• handleSubmit: This function handles the form submission when the user presses Enter or clicks the send button. It prevents default form submission behavior. Here's a breakdown of the logic:

  • Adds the user's message to the messages state.
  • Disables the input field temporarily using disableForBot to prevent user input during bot response.
  • Simulates bot response by adding a bot message to the messages state after a 1-second delay.
  • Clears the user input field after sending the message.

Message Rendering:

The component iterates through the messages state array using map and renders each message using AnimatePresence and motion from react-motion. This enables animations for new messages and bot typing simulation.

• Message Box:

  • A conditional statement applies different styles to the message box depending on the sender ("bot" or "user").
  • The message text is displayed within the box.

• Bot Typing Animation:

  • An AnimatePresence component controls the animation for the bot typing indicator.
  • When isTyping is true, a motion div with the message "Bot is listening ..." fades in and moves up from the bottom.
  • The animation includes styles for the text and a spinner icon.

Input Field:

• The input field component is wrapped in a form element to handle form submission.
• The disabled state of the input field is controlled by the disableForBot state variable.
• A button is positioned absolutely at the right end of the input field to trigger form submission.

Overall, this code snippet demonstrates a well-structured React component with state management, user interactions, and animations to create an engaging chatbox experience.

Additional Notes for Advanced Developers:

• The code utilizes framer-motion for animations. Consider exploring advanced animation concepts and customization options provided by the library.
• Error handling and edge cases can be further implemented to improve robustness.
• The current implementation simulates a simple bot response. In a real-world scenario, you might integrate with a chatbot API for more intelligent interactions.
