📄 中文摘要
认证系统在生产环境中面临复杂挑战，尤其是在会话管理方面，现有 JWT 库在令牌创建和验证方面表现出色，但在会话感知、刷新令牌轮换、令牌撤销、设备与 IP 追踪、暴力破解限速以及未来安全扩展性等关键生产需求上存在不足。为解决这些痛点，一个开源认证引擎应运而生，旨在提供全面的会话管理功能。该引擎通过集成先进的会话管理策略，确保了系统在面对真实世界复杂性时的鲁棒性和安全性。其设计理念强调模块化和可扩展性，允许开发者根据特定需求进行定制和功能增强。该项目利用人工智能辅助开发，提升了开发效率和代码质量，为 Node.js 生态系统提供了一个功能完备、生产就绪的认证解决方案，有效弥补了现有 JWT 方案在会话管理方面的空白，显著提升了后端系统的安全性和用户体验。
📄 English Summary
I Built an Open-Source Authentication Engine for Node.js (with the Help of AI)
Authentication systems, while seemingly straightforward, present significant complexities in production environments, particularly concerning session management. Existing JWT libraries excel at token creation and verification but fall short in critical production-grade functionalities. Real-world backend systems demand features such as session awareness, refresh token rotation, token revocation (e.g., 'logout all devices'), device and IP tracking, rate limiting against brute-force attacks, and extensibility for future security needs. To address these shortcomings, an open-source authentication engine has been developed, specifically designed to provide comprehensive session management capabilities for Node.js applications. This engine integrates advanced session management strategies, ensuring robustness and security in complex operational scenarios. Its modular and extensible architecture allows developers to customize and enhance functionalities according to specific requirements. The project leveraged AI assistance during development, which significantly boosted efficiency and code quality. This initiative offers a production-ready authentication solution for the Node.js ecosystem, effectively bridging the gap left by conventional JWT implementations in session management and substantially enhancing the security and user experience of backend systems.
