Lucia is a simple and flexible user and session management library that provides an abstraction layer between your app and your database. It's bare-bones by design, keeping everything easy to use and understand.

Working with Lucia looks something like this. In the code below, you're creating a new user with an email/password method, creating a new session, and creating a cookie that you can set to the user.

const user = await auth.createUser({
	key: {
		providerId: "email",
		providerUserId: email,
		password
	},
	attributes: {
		email
	}
});
const session = await auth.createSession({
	userId: user.userId,
	attributes: {}
});
const sessionCookie = auth.createSessionCookie(session);
