Prisma

The @lucia-auth/adapter-prisma package provides adapters for Prisma.

npm install @lucia-auth/adapter-prisma

Schema

While Lucia does not enforce model names, the relation name (user) in the session model must be the camel-case version of the user model name. For example, if the user model was named AuthUser, the relation must be named Session.authUser.

User ID can be numeric (see Define user ID type) but session ID must be a string type.

model User {
  id       String    @id
  sessions Session[]
}

model Session {
  id        String   @id
  userId    String
  expiresAt DateTime
  user      User     @relation(references: [id], fields: [userId], onDelete: Cascade)
}

Usage

PrismaAdapter takes a session and user model.

import { PrismaAdapter } from "@lucia-auth/adapter-prisma";
import { PrismaClient } from "@prisma/client";

const client = new PrismaClient();

const adapter = new PrismaAdapter(client.session, client.user);
