Initialize Web3AI project with Node.js, Python, and OpenAI integration

[Copilot]

Establishes foundational structure for Web3AI toolkit integrating AI capabilities with blockchain development.

Project Structure

• backend/ - Node.js modules for API integration
• ai_scripts/ - Python scripts for AI processing
• index.js - Application entry point with API key validation
• .env.example - Environment variable template

Node.js Setup

• Dependencies: dotenv, openai
• backend/openai.js - OpenAI SDK wrapper with chat completion examples
• Startup script validates API key presence before execution

Python Integration

• ai_scripts/sample_ai.py - Demonstrates smart contract analysis and Web3 concept explanations
• requirements.txt - Python dependencies (openai, python-dotenv)

Usage Example

npm install
cp .env.example .env
# Add OPENAI_API_KEY=sk-...
npm start

// backend/openai.js
const completion = await openai.chat.completions.create({
  model: "gpt-3.5-turbo",
  messages: [
    { role: "system", content: "You are a Web3 expert..." },
    { role: "user", content: prompt }
  ]
});

Documentation

Comprehensive README covers:

• Node.js and Python prerequisites
• OpenAI API key generation
• Installation and configuration
• Project architecture

Original prompt

Problem:

You want to start the Web3AI project by setting up a basic foundation that integrates several key AI and development tools.

Solution:

I will create a project structure from scratch and integrate the following components:

1. Node.js Setup: Initialize a Node.js project with a package.json file, and install necessary dependencies like dotenv for environment variables.

2. NPM (Node Package Manager): Use NPM to install and manage project dependencies.

3. OpenAI API Integration: Add a configuration file to manage the OpenAI API key (e.g., .env file and a utility module to interact with OpenAI's API using their SDK).

4. Python Integration:

   • Include Python backend capabilities.
   • Create a sample script demonstrating interaction with OpenAI's Python library (like sending requests to an AI model).

5. Basic Project Structure:

   • Set up folders for the backend code (/backend) and AI Python scripts (/ai_scripts).
   • Add example files demonstrating usage of Node.js for backend and Python for AI tasks.

Deliverables:

1. package.json: Initialized with dependencies such as dotenv and openai for Node.js.
2. .env.example: A template for managing environment variables, including the OpenAI API key.
3. index.js: An entry point for the Node.js backend.
4. openai.js: A Node.js script showcasing how to connect to OpenAI's API.
5. ai_scripts/sample_ai.py: A Python script demonstrating AI functionality with OpenAI's Python library.
6. Installation instructions in the README file for setting up Node.js, Python, and generating an OpenAI API key.

This setup will serve as the foundation, making it easy to expand with additional AI or blockchain features in the future.

Pull request overview

This pull request initializes a new Web3AI project that integrates AI capabilities (via OpenAI) with blockchain development tools. The project establishes a dual-language foundation with Node.js for the backend/API layer and Python for AI processing scripts.

Changes:

• Created foundational project structure with separate directories for Node.js backend and Python AI scripts
• Integrated OpenAI SDK in both Node.js (backend/openai.js) and Python (ai_scripts/sample_ai.py) with chat completion examples
• Set up environment configuration with .env.example template and validation for API keys
• Added comprehensive documentation in README.md covering installation, configuration, and usage for both language environments

The error status check uses error.status === 401, but the OpenAI SDK typically uses error.code or error.response?.status for HTTP status codes. Verify that error.status is the correct property for the version of the OpenAI SDK being used (v6.10.0). If the property doesn't exist, this condition will never be true and the helpful error message won't be displayed to users.

The README references a specific GitHub repository URL (https://github.com/lippytm/Web3AI.git) which may not be correct for all users of this project. Consider using a placeholder like https://github.com/yourusername/Web3AI.git or removing the specific username to make the documentation more generic and reusable.

The OpenAI client is initialized at module load time (line 11-13), but process.env.OPENAI_API_KEY may not be defined yet if require('dotenv').config() hasn't been called. This module depends on the parent module (index.js) to call dotenv.config() first. Consider calling require('dotenv').config() at the top of this module to make it self-contained and prevent initialization errors if this module is imported elsewhere.
