WahGPT - WhatsApp Chatbot with GPT Integration

WahGPT is a WhatsApp chatbot built using the whatsapp-web.js library, allowing users to interact with an intelligent chatbot powered by GPT (ChatGPT) and create DALL·E-generated images. This README provides a comprehensive explanation of the code structure and functionality.

Features

WhatsApp Integration: Utilizes whatsapp-web.js to connect to the WhatsApp Web platform, enabling the bot to send and receive messages.
GPT Integration: Communicates with the ChatGPT API to generate responses based on user input.
DALL·E Integration: Generates images using the DALL·E API in response to specific commands.

Getting Started

Prerequisites

Node.js and npm installed on your machine.
WhatsApp account and a phone with an active internet connection.

Installation

Clone the repository:

git clone https://github.com/well300/WahGPT.git

Navigate to the project directory:
```
cd WahGPT
```
Install dependencies:
```
npm install
```
Create a .env file in the root directory with the following content:
```
CHATGPT_API_URL=https://ultimetron.guruapi.tech/gpt4
DALLE_API_URL=https://aemt.me/dalle
```
Replace the URLs with the actual endpoints you want to use.
Run the application:
```
npm start
```
Scan the QR code displayed with your WhatsApp Web to authenticate.

Code Structure

1. Initialization

The script initializes the WhatsApp client and sets up event listeners for authentication, QR code display, and readiness.

2. API URL Configuration

Environment variables are used to configure the URLs for the ChatGPT and DALL·E APIs. This allows for easy modification without altering the code.

const apiUrl = `${process.env.CHATGPT_API_URL}?text=${encodeURIComponent(text)}`;

3. Message Processing

The message event listener handles incoming messages. It checks for specific commands, interacts with APIs, and sends appropriate responses.

3.1. ChatGPT Integration

The getChatGPTResponse function makes a request to the ChatGPT API and processes the response.

3.2. DALL·E Integration

The getDALLEImage function generates images using the DALL·E API in response to the /dalle command.

4. Response Formatting

Responses are formatted with emojis based on certain conditions or keywords in the reply.

// Add emojis based on conditions or keywords in the response
if (response.toLowerCase().includes("hello")) {
  emojiResponse += " 👋";
} else if (response.toLowerCase().includes("thank you")) {
  emojiResponse += " 🙏";
}

5. Error Handling

The script includes error handling to gracefully manage API errors and other exceptions.

Usage

Send messages to the WhatsApp number associated with the bot.
Use the /dalle command to generate DALL·E images based on text input.
Experience intelligent responses generated by ChatGPT.
