Is it correct to use string for primary key sequelize?
Faced a problem when you need to display the category as a string to show in ui, but got the id as a number,
now I changed it to a string and I'm not sure if this is the right solution?

const Category = sequelize.define('category', {
  // id: { type: DataTypes.INTEGER, primaryKey: true, autoIncrement: true },
  category: { type: DataTypes.STRING, primaryKey: true, unique: true, allowNull: false },
})

Answer 1

Purely theoretically, this is not very good: it is much less convenient to make indexes on the lines of the base than on uuids or numbers. But until you are designing a highly loaded system with millions of inserts per minute, make an architecture that is comfortable for you to use and don't listen to Nazi code.
