Incorporating a user ID (foreign key) into a MySQL table using NextJS and Prisma

Currently, I am in the process of developing an online recipe platform that allows users to log in and share their recipes. The technology stack I am using includes NextJS, Prisma, and MySQL DB. User authentication is handled with NextAuth and a credentials provider utilizing usernames and passwords. My challenge lies in establishing a foreign key constraint between the users table and recipe tables by linking them through a userID. Each recipe should be associated with a specific user, but I am unsure how to retrieve the current session data containing only the username and then relate it to the user's auto-incremented userID stored in Prisma. Is there any feasible method to link a user to a recipe solely based on next auth credentials (username and password)?

Answer №1

If you want to personalize what information is added to the JWT and session in your NextAuth setup, you have the ability to do so.

Below is an example of how you can insert the userId into both the JWT and session:

import NextAuth from 'next-auth'
import Providers from 'next-auth/providers'
import Adapters from 'next-auth/adapters'
import prisma from '../../../db' // your prisma client

export default NextAuth({
  providers: [
    Providers.Credentials({
      // Your credentials provider configuration
    })
  ],
  adapter: Adapters.Prisma.Adapter({ prisma }),
  secret: process.env.SECRET,
  callbacks: {
    async jwt(token, user) {
      // Initial sign in
      if (user) {
        token.id = user.id
      }
      return token
    },
    async session(session, token) {
      // Add property to session, like `userId`
      session.userId = token.id
      return session
    }
  }
})

In your API routes, you can now access `userId` directly from the session:

import { getSession } from "next-auth/client";

export default async (req, res) => {
  const session = await getSession({ req });
  console.log(session.userId);  // you can use this id to link the user with the recipe
  // your code here
}

This implementation ensures that whenever a user logs in, their userId will be included in both the JWT and session data.
