Replace hand-written TypeScript interfaces and serde_json::Value responses
with ts-rs generated bindings across admin, metrics, timeline, and WebSocket
APIs. Eliminates manual type maintenance and ensures frontend types stay
in sync with backend definitions.
Implements POST /api/timeline endpoint that aggregates enrollment by
subject over 15-minute slots, filtering courses by their actual meeting
times. Includes ISR-style schedule cache with hourly background refresh
using stale-while-revalidate pattern, database indexes for efficient
queries, and frontend refactor to dynamically discover subjects from API.
Replace simple auto-matching with scored candidate generation that
considers department overlap, name uniqueness, and rating volume.
Candidates above 0.85 auto-accept; others require admin approval.
Integrate ts-rs for Rust-to-TypeScript type generation, build course
search page with filters, pagination, and expandable detail rows,
and refactor theme toggle into a reactive store with view transition
animation.
Switch to Bun for 2-5x faster frontend builds, implement cargo-chef for
reliable Rust dependency caching, and add Biome for fast code
formatting.
Build system improvements:
- Replace pnpm with Bun for frontend package management
- Add cargo-chef to Dockerfile for better Rust build layer caching
- Update all commands to use bun instead of pnpm
Developer experience:
- Add comprehensive Justfile commands (format, format-check, db)
- Implement automated PostgreSQL Docker setup with random port
allocation
- Add stricter checks (--deny warnings on clippy, --all-features flag)
Code quality:
- Add Biome formatter for 10-100x faster TypeScript/JavaScript
formatting
- Add GitHub Actions CI/CD workflow for automated checks
- Update .dockerignore with comprehensive exclusions
- Format all code with cargo fmt (Rust) and Biome (TypeScript)
All changes maintain backward compatibility and can be tested
incrementally.
Add comprehensive ESLint setup with React and TypeScript support, create basic integration tests for the shutdown utilities, and enhance the Justfile with a new check command that runs all validation steps (cargo check, clippy, tests, and linting).
