How do I seed data in Sequelize?

To seed data in Sequelize, you can create a seed file using the Sequelize CLI. Would you like a step-by-step guide?

Yes, please provide the steps.

First, ensure you have the Sequelize CLI installed. Then, run sequelize seed:create --name demo-user to create a seed file.

What should I include in the seed file?

In the seed file, you should define the up and down methods. Use queryInterface.bulkInsert to add data in the up method.

Can you show me an example of a seed file?

Sure! Here's a simple example:

'use strict';

module.exports = {
  up: async (queryInterface, Sequelize) => {
    await queryInterface.bulkInsert('Users', [{
      name: 'John Doe',
      email: '[email protected]',
      createdAt: new Date(),
      updatedAt: new Date()
    }], {});
  },

  down: async (queryInterface, Sequelize) => {
    await queryInterface.bulkDelete('Users', null, {});
  }
};
