Answer 1

Group by with count sequelize ORM

'field' - you can rename this string, it's your field(column) in database

'count' - reserved string need for get count in sequelize

'cnt' - you can rename this string, it's your output count

Sequelize version 3.25.0

User.findAll({
      attributes: ['field', [sequelize.fn('count', sequelize.col('field')), 'cnt']],
      group: ['field'],
})
