Lucia

Lucia is an open-source project designed to be a comprehensive resource for developers implementing authentication in JavaScript and TypeScript applications. It offers detailed guides, tutorials, and example projects that cover a wide range of authentication concepts, from basic session management to advanced features like multi-factor authentication (2FA) and WebAuthn. The project emphasizes practical implementation, providing code examples and best practices to help developers build secure and robust authentication systems.

The core value proposition of Lucia lies in its educational approach and practical examples, enabling developers to understand and build their authentication logic rather than relying on black-box solutions. It covers critical aspects like managing user sessions, integrating with popular OAuth providers (GitHub, Google), and implementing rate limiting to protect against abuse. While it provides foundational components and guidance, developers are expected to integrate these into their specific application frameworks and database systems, offering flexibility and control over the final implementation.
