x402ApiHub

Overview

x402ApiHub is a comprehensive API hub designed for blockchain base operations. It provides a robust backend service built with Node.js and TypeScript, offering RESTful APIs for managing courses, categories, and other blockchain-related data. The project is structured to host both backend and frontend components, ensuring a full-stack solution for decentralized applications on the Base blockchain network.

This project serves as the central hub for API interactions, enabling seamless integration between frontend applications, backend services, and blockchain operations. It is engineered for scalability, security, and maintainability, following industry best practices for modern web development.

Features

• RESTful API Endpoints: Comprehensive API routes for courses, categories, and blockchain data management
• TypeScript Integration: Full type safety and enhanced developer experience
• Modular Architecture: Organized structure with separate modules for routes, models, and configuration
• Database Integration: Support for data persistence and retrieval
• Blockchain Base Compatibility: Optimized for Base blockchain network operations
• Scalable Backend: Built with Express.js for high-performance API serving
• Environment Configuration: Flexible configuration management for different deployment environments

Architecture

The project follows a modular architecture separating concerns between backend and frontend components:

Component Breakdown

• Frontend Layer: User interface components and client-side logic (planned for future implementation)
• Backend API Layer: Core business logic, API endpoints, and service integrations
• Database Layer: Data persistence and retrieval mechanisms
• Blockchain Integration: Direct interaction with Base blockchain network
• Authentication Service: User authentication and authorization
• Data Validation Service: Input validation and data integrity checks
• Blockchain Integration Service: Smart contract interactions and transaction management

Installation

Prerequisites

• Node.js 18 or higher
• pnpm package manager
• Git

Setup Instructions

1. Clone the repository

   git clone https://github.com/your-repo/x402ApiHub.git
   cd x402ApiHub
   

2. Install backend dependencies

   cd backend
   pnpm install
   

3. Environment configuration

   • Copy .env.example to .env
   • Configure environment variables (database connection, blockchain endpoints, etc.)

4. Database setup

   • Ensure database is running and accessible
   • Run database migrations if applicable

5. Build and run

   pnpm run build
   pnpm start
   

Usage

API Endpoints

The backend provides the following primary API endpoints:

• GET /api/courses - Retrieve all courses
• POST /api/courses - Create a new course
• GET /api/categories - Retrieve all categories
• POST /api/categories - Create a new category

Development

For development with hot reloading:

cd backend
pnpm run dev

Testing

cd backend
pnpm test
