Dead simple database seeding framework for NodeJS

This project is basically abandoned. I want to work on it, but the Cobbler goes without shoes. I just don't have time.

mysql-db-seed

Dead simple database seeding framework for NodeJS

Only support for MySQL

Usage

Installation

$ npm install --save-dev mysql-db-seed

Usage

Pass the method as a callback to get new data. Using Faker.JS:

// dbseeder.js
const faker = require("faker");
const Seeder = require("mysql-db-seed").Seeder;
// ES6 use `import {Seeder} from "mysql-db-seed";`

// Generate a new Seeder instance
const seed = new Seeder(
  10, 
  "db_host",
  "db_username",
  "db_password",
  "database"
);

(async () => {
  await seed.seed(
    30,
    "users", 
    {
      email: faker.internet.email,
      profile_picture: faker.image.people,
      first_name: faker.name.firstName,
      last_name: faker.name.lastName,
      uuid: faker.random.uuid,
      created_at: seed.nativeTimestamp(),
      updated_at: seed.nativeTimestamp()
    }
  )
  seed.exit();
  process.exit();
})();

Then, node dbseeder.js
