Create a placeholder class for the Form Builder group component within an Angular application

Question

Create a placeholder class for the Form Builder group component within an Angular application

Currently, I am in the process of creating numerous new forms. For instance:

  constructor(private formBuilder: FormBuilder) {

    this.userForm = this.formBuilder.group({
      'name': ['', Validators.required],
      'email': ['', [Validators.required, ValidationService.emailValidator]],
      'profile': ['', [Validators.required, Validators.minLength(10)]]
    });
  }

Instead of directly declaring these new values, wouldn't it be more efficient to create a separate class containing this information? Something like:

export class UserValidator{
  // implementation details here
}

And then use it like:

 this.userForm = this.formBuilder.group({
      UserValidator
    });

Is there any concrete example that demonstrates this approach?

If you want to streamline your code, consider creating a custom class for this purpose:

export class ProfileUser {
  firstName: string;
  lastName: string;
  email: string;

  generateForm() {
    return {
      firstName: [this.firstName, Validators.required],
      lastName: [this.lastName, Validators.required],
      email: [this.email, [Validators.required, ValidationService.emailValidator]]
    };
  }
}

You can then use the class like so:

const newUser = new ProfileUser();
newUser.firstName = 'Jane';
newUser.lastName = 'Doe';
this.form = this.fb.group(newUser.generateForm());
