Java EE 8 and Angular

Setting up forms with FormBuilder

In the earlier reactive example seen, we built the FormGroup and FormControl instances without using a FormBuilder. A more convenient option is to make use of the FormBuilder which leads to setup code like the following, which is simpler to read:

constructor(fb: FormBuilder) {     this.formGroup = fb.group({      email: null,      phone: null    });}

Arguably, the benefits of a builder aren't evident if you have only one or two controls. A builder adds syntactical convenience, which you do require for readability. There are more options for setup when adding validations and initial values, as we will see in the next section.
