Lucia is a TypeScript authentication library for managing user sessions and OAuth in web applications. It was deprecated in March 2025 and now exists as a single-file reference implementation plus the Auth Book learning resource.
Use cases
- add user authentication to a web app
- implement session-based login in TypeScript
- handle OAuth sign-in flows
- manage user sessions with cookies
- learn how authentication works under the hood
When to choose
- you want a minimal, understandable reference implementation of session auth
- you are learning authentication concepts via the Auth Book
- you want to copy a single-file auth solution into your project
When to avoid
- you need a maintained library with ongoing security updates
- you want batteries-included auth with providers and UI out of the box
- you are starting a new production project in 2025 or later
