StateSet API

StateSet API is a comprehensive, scalable, and robust backend system for order management, inventory control, returns processing, warranty management, shipment tracking, and work order handling. Built with Rust, it leverages modern web technologies and best practices to provide a high-performance, reliable solution for e-commerce and manufacturing businesses.

Features

• Order Management:

  • Create, retrieve, update, and delete orders
  • Support for complex order workflows and statuses

• Inventory Control:

  • Real-time inventory tracking across multiple locations
  • Automated reorder point notifications

• Returns Processing:

  • Streamlined return authorization and processing
  • Integration with refund and exchange systems

• Warranty Management:

  • Track and manage product warranties
  • Automated claim processing and resolution

• Shipment Tracking:

  • Real-time tracking integration with major carriers
  • Custom shipment status notifications

• Manufacturing & Production:

  • Supplier management and communication
  • Bill of materials (BOM) tracking and version control

• Work Order Handling:

  • Create and manage work orders for repairs or modifications
  • Track work order progress and resource allocation

Tech Stack

Our carefully selected tech stack ensures high performance, scalability, and maintainability:

Core Technologies

• Language: Rust (for performance and safety)
• Web Framework: Axum (lightweight and fast asynchronous web framework)
• Database: PostgreSQL with SQLx (for robust, async operations)

ORM and Query Building

• SeaORM (async ORM for Rust, providing powerful database operations)

API Protocols and Services

• REST: Handled natively by Axum
• GraphQL: Async-Graphql (high-performance GraphQL server library for Rust)
• gRPC: Tonic (for efficient, type-safe gRPC support)

Caching and Messaging

• Caching: Redis (for high-speed data caching)
• Message Queue: RabbitMQ (for reliable async processing)

Observability

• Metrics: Prometheus (for detailed system monitoring)
• Tracing: OpenTelemetry with Jaeger (for distributed tracing)
• Logging: slog (for structured, efficient logging)

Architecture

StateSet API follows a modular, event-driven architecture designed for scalability and maintainability.

Key Components

• Services: Implement core business logic
• Handlers: Process HTTP requests
• Commands: Handle write operations
• Queries: Manage read operations
• Events: Enable asynchronous processing
• Models: Represent domain entities
• Middleware: Provide cross-cutting concerns (auth, rate limiting, etc.)

Getting Started

Prerequisites

Ensure you have the following installed:

• Rust (latest stable version)
• PostgreSQL
• Redis
• RabbitMQ
• Jaeger (for distributed tracing)

Installation

1. Clone the repository:

   git clone https://github.com/yourusername/stateset-api.git
   cd stateset-api

2. Set up the environment variables:

   cp .env.example .env
   # Edit .env with your configuration

3. Build the project:

   cargo build

4. Run database migrations:

   cargo run --bin migrate

5. Start the server:

   cargo run

The API will be available at http://localhost:8080.

Troubleshooting

• If you encounter database connection issues, ensure PostgreSQL is running and the connection details in .env are correct.
• For RabbitMQ connection problems, verify that the service is running and the credentials are set correctly.

API Documentation

Comprehensive API documentation is available at https://docs.stateset.com/api-reference/authentication.

Quick Start

1. Authenticate:

   curl -X POST https://api.stateset.com/v1/auth/login \
     -H "Content-Type: application/json" \
     -d '{"email": "user@example.com", "password": "your_password"}'

2. Create an order:

   curl -X POST https://api.stateset.com/v1/orders \
     -H "Authorization: Bearer YOUR_TOKEN" \
     -H "Content-Type: application/json" \
     -d '{"customer_id": "cust_123", "items": [{"product_id": "prod_456", "quantity": 2}]}'

Testing

Run the comprehensive test suite:

cargo test

For integration tests:

cargo test --features integration

Deployment

Deploy using Docker:

docker build -t stateset-api .
docker run -p 8080:8080 stateset-api

For production deployments, we recommend using Kubernetes for orchestration and scaling.

Performance

StateSet API is designed for high performance and scalability:

• Handles 10,000+ requests per second on a single node
• Scales horizontally for increased load
• 99.99% uptime SLA

Roadmap

Our upcoming features and improvements:

• Advanced analytics and reporting dashboard
• Machine learning-based demand forecasting
• Blockchain integration for supply chain transparency
• Expanded international shipping and compliance features
