Object returned by require("unimapperjs") contains property type. This property contains getters for:

• string
• number
• boolean
• date
• uuid
• foreign

This getters return new instances of Type and allow you to change behavior with method chaining.

• length(number)
• default(valueOrFunctionReturningValue)
• nullable() - allow inserting nulls
• unique() - tell that value must be unique
• primary() - add primary key

• length(number) - length of number when in string (not stored as string for sure) it tells how big numbers you want to store
• decimals(numberOfDecimals)
• autoIncrement() - enable automatic incerementing for integers (no decimals set)
• default(valueOrFunctionReturningValue)
• nullable() - allow inserting nulls
• unique() - tell that value must be unique
• primary() - add primary key

• default(valueOrFunctionReturningValue)
• nullable() - allow inserting nulls

• length(number)
• default(valueOrFunctionReturningValue)
• now() - equals to default(() => new Date())
• nullable() - allow inserting nulls
• unique() - tell that value must be unique
• primary() - add primary key

Uuid by RFC4122

• unique() - tell that value must be unique
• notPrimary() - in default Uuid is marked as primary

• constructor(entityName: string) - you must declare foreign as foo = type.foreign("Foo")
• withForeign(field: ((map: TEntity) => any) | string) - creating *:1 relation, marking (number, uuid) field inside entity where this foreign type is
• hasMany(foreignField: ((map: TEntity) => any) | string) - creating *:N relation, marking (number, uuid) field in related entity which points to this entity
