Updating schema file

after the file has been updated with new schema details, a new migration needs to be run

npx prisma migrate --name init

then we can run the command below to reset and set new seed

How to clear the Database and rerun seeds

npx prisma migrate reset

how to run seed command

before being able to run seed command, you need to enable seeding in the packag.json file add this key/val pair to package json root

	"prisma": {
    "seed": "ts-node --compiler-options {\"module\":\"CommonJS\"} prisma/seed.ts"
  }

the --compiler-options {\"module\":\"CommonJS\"} part is for next.js

now we can run seed command npx prisma db seed should work if seed file created already

Boiler-plate seed file

import { PrismaClient, Prisma } from "@prisma/client";

const prisma = new PrismaClient();

const userData: Prisma.UserCreateInput[] = [
  {
    email: "email@gmail.com",
    password: "$2b$04$C/l6kQt/LCNxp4HTR.fZde2mN68ppAyhx7rf1nFAWOza.YqzGNylK",
  },
];

async function main() {
  console.log(`Start seeding ...`);
  for (const u of userData) {
    const user = await prisma.user.create({
      data: u,
    });
    console.log(`Created user with id: ${user.id}`);
  }
  console.log(`Seeding finished.`);
}

main()
  .then(async () => {
    await prisma.$disconnect();
  })
  .catch(async (e) => {
    console.error(e);
    await prisma.$disconnect();
    process.exit(1);
  });
