A-Form built with Angular Reactive Forms

I built a reusable component module to streamline the creation of Angular Reactive Forms

Angular Reactive Forms are a way to manage and validate form inputs in Angular applications. They provide a more programmatic and flexible approach to handling forms compared to Template-Driven Forms, which rely on two-way data binding. Reactive Forms are a powerful and versatile way to work with forms in Angular applications.

Reactive Forms offer a more structured and maintainable way to work with forms in Angular applications, particularly in complex scenarios with complex validation requirements or dynamic form elements.

To use Reactive Forms in an Angular application, you need to import the necessary modules, create a form model using the FormBuilder, define your form controls and validation rules, and then bind the form controls to HTML elements in your template using directives like formControlName.

My AForm Module allows you to skip the process of importing the dependencies and writing a Reactive form by providing a data object to the AForm component.

For Example:

Template:

<aform
class="flex-justify-content-center" width="200"
(onSubmit)="onSubmit($event)"
(onChange)="onChanges($event)"
[fields]="fields"
submitButton="Submit"
cancelButton="Cancel">
<p title>Example Sign Up Form</p>
</aform>

Script

public fields = [
{
type: 'text',
name: 'name',
label: 'Name',
validators: ['required'],
},
{
type: 'email',
name: 'email',
label: 'Email',
validators: ['required', 'email'],
errors: {
email: 'A valid email is required',
},
},
{
type: 'password',
name: 'password',
label: 'Password',
validators: ['required', this.getPasswordValidator()],
errors: {
uppercase: 'Uppercase characters required.',
lowercase: 'Lowercase characters required.',
numbers: 'Numbers required.',
special: 'Special characters required.',
length: 'Must be 8 characters',
},
},
{
type: 'password',
name: 'confirm',
label: 'Confirm Password',
validators: ['required'],
asyncValidators: [this.getAsyncPasswordMatch()],
errors: {
passwordsMatch: 'Passwords do not match.',
},
},
];
