let createdAt = {
[Op.lt]: new Date(date),
[Op.gte]: new Date().setHours(0, 0, 0, 0)

i need record of every hour with amount of that hour. how to do this?
group:[] is use in sequelize to return data by groups. your code will be like this
if (ExpenseGraphTimeSeries === 'today') {
let date = new Date(Date.now());
let createdAt = {
[Op.lt]: new Date(date),
[Op.gte]: new Date().setHours(0, 0, 0, 0)
};
ExpenseGraphCondition.createdAt = createdAt
ExpenseGraph = await model.Expense.findAll({
where: createdAt,
attributes: [
[model.sequelize.fn('sum', model.sequelize.col('Amount')), 'expense'], 'createdAt'
],
group: [model.sequelize.fn('hour', model.sequelize.col('createdAt'))],
order: [['id', 'asc']], //optional
});
}
