index.js

import { faker } from "@faker-js/faker";
import { promises as fs } from "fs";

const users = Array.from({ length: 1000 }, (_, i) => ({
  name: faker.name.fullName(),
  tel: faker.phone.number("###-###-####"),
  img: faker.image.avatar(),
})).map((user) => {
  const { name } = user;
  const [firstName, lastName] = name.split(" ");
  return {
    ...user,
    email: faker.internet.email(firstName, lastName),
  };
});

fs.writeFile("./db.json", JSON.stringify({ users }, null, 2), "utf8");
