How do I set up seeding in Sequelize?

To set up seeding in Sequelize, you need to create a seed file and define the data you want to insert.

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, {});
  }
};

How do I run the seed file after creating it?

You can run the seed file using the command: npx sequelize-cli db:seed:all. This will execute all seed files.

What if I want to undo the seeding?

To undo the seeding, you can use the command: npx sequelize-cli db:seed:undo:all. This will revert all seeded data.
