OxiCloud Development Guide

Build Commands

# Core development workflow
cargo build                 # Build the project
cargo run                   # Run the project locally (server at http://127.0.0.1:8085)
cargo check                 # Quick check for compilation errors without building

# Testing commands
cargo test                  # Run all tests
cargo test -- --nocapture   # Run tests with output displayed
cargo test <test_name>      # Run a specific test (e.g., cargo test file_service)
cargo test domain::entities::file::tests::test_create_file  # Run a specific test function
RUST_LOG=debug cargo test   # Run tests with debug-level logging
RUST_LOG=trace cargo test   # Run tests with trace-level logging

# Code quality tools
cargo clippy                # Run linter to catch common mistakes
cargo clippy --fix          # Fix auto-fixable linting issues
cargo fmt --check           # Check code formatting without changing files
cargo fmt                   # Format code according to Rust conventions

# Debugging
RUST_LOG=debug cargo run    # Run with detailed logging for debugging
RUST_BACKTRACE=1 cargo run  # Run with full backtrace for better error diagnostics

Code Style Guidelines

• Architecture: Follow Clean Architecture with clear layer separation (domain → application → infrastructure → interfaces)
• Naming: Use snake_case for files, modules, functions, variables; PascalCase for types/structs/enums
• Modules: Use mod.rs files for explicit exports with visibility modifiers (pub, pub(crate))
• Error Handling: Use Result<T, E> with thiserror for custom error types; propagate errors with ? operator
• Comments: Document public APIs with /// doc comments, explain "why" not "what"
• Imports: Group imports: 1) std, 2) external crates, 3) internal modules (with blank lines between)
• Async: Use async-trait for repository interfaces; handle futures with .await and tokio runtime
• Testing: Write unit tests in the same file as implementation (bottom of file, in a tests module)
• Dependencies: Use axum for web API, tower-http for middleware, serde for serialization
• Logging: Use tracing with appropriate levels (debug, info, warn, error) and structured contexts
• Repository Pattern: Define interfaces in domain layer, implement in infrastructure layer
• I18n: Store translations in JSON files under static/locales/, use i18n service for text lookups
• Type Safety: Prefer strong typing with domain-specific types over primitive types
• Error Messages: Provide clear, actionable error messages that help diagnose the issue

Project Structure

OxiCloud is a NextCloud-like file storage system built in Rust with a focus on performance and security. It provides a clean REST API and web interface for file management using a layered architecture approach:

• Domain Layer: Core business logic and entities (src/domain/)
• Application Layer: Use cases and application services (src/application/)
• Infrastructure Layer: External systems and implementations (src/infrastructure/)
• Interfaces Layer: API and web controllers (src/interfaces/)

The roadmap in TODO-LIST.md outlines planned features including enhanced folder support, file previews, user authentication, sharing, and a sync client.
