StateSet API: Modern Backend Framework
A high-performance, scalable backend framework built with Rust, Axum, and SeaORM for enterprise-grade applications.
StateSet API: A Robust Backend Framework
StateSet API is a modern, scalable, and reliable backend system designed for enterprise-grade web services. Built with Rust, it leverages cutting-edge web technologies and best practices to deliver a high-performance infrastructure solution. It is particularly well-suited for e-commerce and manufacturing businesses, adept at handling order management, inventory control, returns processing, warranty management, shipment tracking, and work order handling.
Core Features
StateSet API is built to handle complex business operations. Here’s a breakdown of its key features:
- Order Management: Full CRUD operations for orders, support for complex workflows and statuses.
- Inventory Control: Real-time tracking across multiple locations, automated reorder point notifications.
- Returns Processing: Streamlined return authorization, processing, and integration with refund and exchange systems.
- Warranty Management: Track and manage product warranties, handle automated claim processing.
- Shipment Tracking: Real-time integration with major carriers, custom shipment status notifications.
- Manufacturing & Production: Supplier management, BOM tracking, and version control.
- Work Order Handling: Create and manage work orders, track progress, and manage resource allocation.
Tech Stack: The Foundation of Performance
Our carefully selected tech stack ensures high performance, scalability, and maintainability.
Core Technologies
- Language: Rust (for performance, safety, and concurrency)
- Web Framework: Axum (a lightweight, async, and fast web framework)
- Database: PostgreSQL (for robust, reliable data storage) with SQLx (for async operations).
ORM and Query Building
- SeaORM (a powerful async ORM for Rust).
API Protocols and Services
- REST: Implemented natively with Axum.
- GraphQL: Implemented using Async-GraphQL for a high-performance GraphQL API.
- gRPC: Built with Tonic for efficient, type-safe gRPC support.
Caching and Messaging
- Caching: Redis for high-speed data caching.
- Message Queue: RabbitMQ for reliable asynchronous processing.
Observability
- Metrics: Prometheus for detailed system monitoring.
- Tracing: OpenTelemetry with Jaeger for distributed tracing.
- Logging: slog for structured, efficient logging.
Technological Advantages:
- Rust’s Performance & Safety: Guarantees memory safety and prevents common programming errors, leading to a highly reliable and performant API.
- Asynchronous Operations: Utilizing Rust’s async capabilities for high-throughput and non-blocking processing.
- Comprehensive Observability: Enables proactive maintenance and rapid issue resolution.
- Flexible API Protocols: Supports various API protocols, ensuring integration with different client applications and services.
Use Cases:
- E-commerce Platforms: Efficiently manage orders, inventory, shipments, and customer interactions.
- Manufacturing Systems: Streamline production workflows, inventory control, supplier management, and quality assurance.
- Enterprise Solutions: Provides a scalable backend infrastructure for a wide variety of business operations and services.
Architecture: Modular and Event-Driven
StateSet API adopts a modular, asynchronous, event-driven architecture designed for scalability and maintainability.
Key Components
- Services: Implement the core business logic for specific functionalities.
- Handlers: Process incoming HTTP requests, routing them to the appropriate logic.
- Commands: Handle operations that modify data or state in the system (writes).
- Queries: Handle read operations, retrieving data without modifying it.
- Events: Enable asynchronous communication and processing through event triggers.
- Models: Represent domain entities, providing a structured data layer.
- Middleware: Handle cross-cutting concerns like authentication, rate limiting, and logging.
Performance and Reliability
StateSet API is engineered for high performance and reliability:
- Handles 10,000+ requests per second on a single node (This is a claim. If you have concrete benchmarks include them here or state in which conditions you measured this).
- Scales horizontally to accommodate increased load.
- Designed for 99.99% uptime SLA (Include specifics if this is part of an actual SLA).
Code Examples
Here are some representative code snippets to demonstrate the implementation.
Axum Web Service Entrypoint
This code sets up the Axum web service, including routes, middleware, and integration with other services.
This shows the main entry point of the server including the config loading, setup of global services, the route definition, telemetry and the server startup
Handlers: API Request Routing
Here are some examples of how API requests are routed to the correct command.
Create Order Handler
This handler pulls the OrderService from the application state and calls the execute method on the CreateOrderCommand
Close Return Handler
This handler pulls the ReturnService from the application state and calls the execute method on the CloseReturnCommand
Commands: Business Logic Execution
The following shows the Create Order and Close Return commands which handle the business logic.
Create Order Command
This shows the command definition, validation, and execution of the create order command.
Close Return Command
This shows the command definition, and execution of the close return command.
Queries: Data Retrieval
These show the two return queries used by the application.
Get Returns By Order Query
This shows how we can find the returns based on the order ID using SeaORM
Get Returns By Date Range Query
This shows how we can find the returns based on a date range using SeaORM.
