Over three months, Halo contributed to the sparcs-kaist/taxi-back repository by modernizing authentication and chat features with a focus on type safety and maintainability. Halo migrated core modules from JavaScript to TypeScript, introduced Zod-based schema validation, and refactored API endpoints to ensure robust input handling and clearer error responses. By replacing regex checks with enum-based validation and standardizing request handlers, Halo improved data integrity and reduced technical debt. The work included fixing login flow bugs and correcting utility typos, resulting in safer user authentication and more reliable real-time chat. Halo’s efforts enhanced backend reliability using Node.js, Express.js, and MongoDB.

May 2025 monthly summary for sparcs-kaist/taxi-back: Established foundational branching, completed TypeScript migration for core modules (auth, chat, socket) with hardened API typings and refactors, and fixed a critical login flow bug by removing sid handling. This set the stage for more reliable real-time features and faster feature delivery. Key deliverables and commits include: - Branch setup: created initial placeholder branch (commit 73b6a29...). - TS migration and API hardening: auth/chats migration (commits 6498ccb...), details (commit 7d36c0...), added requesthandler type (ee0e2dc...), socket.js migrated to socket.ts (e4323a3...). - Login bug fix: removed sid at login to prevent undefined sid (commit bc2d65d...).
