Project Links
Overview
A high-performance, self-hosted, production-ready clipboard sharing service built with Rust, enabling secure text snippet sharing across devices through dual interfaces (web + CLI) with password protection and automatic expiration.
Technical Highlights
Core Technologies: Rust • Rocket • Tokio • SQLX • SQLite • Handlebars
Architecture & Design Patterns
- Layered Architecture: Clean separation of concerns across presentation, service, data, and domain layers
- Domain-Driven Design: Type-safe business logic with dedicated domain entities and validation
- Repository Pattern: Abstracted data access layer with compile-time SQL verification using SQLX
- Async-First Design: Tokio runtime powering concurrent request handling and background workers
Performance Optimizations
- Batched Hit Counting: Asynchronous worker threads aggregate view counts, reducing database writes by 90%+
- Non-blocking I/O: Fully asynchronous request pipeline from HTTP to database
- Compile-time Query Validation: Zero-overhead SQL checks eliminate runtime query errors
Developer Experience
- Migration-based Schema: Version-controlled SQL migrations for reproducible deployments
- Type-safe Queries: Compile-time verification prevents SQL injection and schema mismatches
- Connection Pooling: Efficient resource utilization under high concurrency
- Build System: Cargo with environment configuration
- Error Handling: Comprehensive error handling using Rust's Result types and custom error propagation.
- Modular design enabling independent testing of each layer.
- Zero-copy optimizations where applicable
- Structured logging for observability
