Features

• Generate complete PC builds within specified budget
• Optimize builds for different purposes (gaming, productivity, content creation, etc.)
• Consider user preferences for specific brands or components
• Include detailed specifications and reasoning for each component
• Caching system to reduce API calls
• Built-in budget validation
• Component categories reference

Installation

npm install pcpartspicker

Usage

const express = require('express');
const createPCPartsGenerator = require('pcpartspicker');

const app = express();
const OPENAI_API_KEY = 'your-api-key-here';

app.use('/pcbuild', createPCPartsGenerator(OPENAI_API_KEY));

app.listen(3000, () => {
  console.log('Server is running on port 3000');
});
