This library provides a means to easily create a reactive form based on a class in Typescript. It should be noted that you must use a class and not just an interface. Interfaces are only a design time construct. Classes however are compiled to create a prototype.
Mark properties to be used in a form with the decorator @FormMember(). You can also provide some options that will affect the behavior of the form.
- context allows the field to become optional. If a context string passed into the form's constructor matches one of the values provided then the field will be included.
- validators allows validators to be assigned to the form control
- mark properties that hold an instance of a class with the @FormGroup() and the form will contain an embedded FormGroup that then contains the fields as decorated on that class.
Classes will be instantiated in the process of building the form. the form will then be patched with the values of that class.
NOTE You must use a class and not an interface. Interfaces are design time only constructs and will not populate the form.
Currently, arrays aren't supported.
