@gerandon/ngx-widgets v18.0.8

NgxWidgets

This library was generated with Angular CLI version 18.x.

Short Description

This is basically a utility-widget Angular library, for creating ControlValueAccessors in an easier way, by implementing and extending the Core classes.

Instead of creating ControlValueAccessor implementations in each of our project, this library provides already defined classes for that functionality.

Built-In components

Be patient with me, I'm trying to figure out what this README should really contain... :)

Core Classes

##Widgets (built-in examples) There are a few custom components, just to present how the core functionality and implementation works and makes the development easier (especially in case of a newly created project)

In the following example you can see a custom CVA implementation built into the library (as widget)

As you can see, instead of defining what our CVA will look like, we could use the Base implementation from the core of the library. That way (as seen) our component will have significantly less code on its TS side and we also reduced redundancy as well. ###BasicInput (component)

@Component({
    selector: 'basic-input',
    templateUrl: './basic-input.component.html',
    styleUrls: ['./basic-input.component.scss'],
    encapsulation: ViewEncapsulation.None,
    providers: [
        {provide: NG_VALUE_ACCESSOR, useExisting: forwardRef(() => BasicInputComponent), multi: true},
        {provide: NG_ASYNC_VALIDATORS, useExisting: forwardRef(() => BasicInputComponent), multi: true},
    ],
})
export class BasicInputComponent extends BaseTextInput<string> implements OnInit {

    constructor(protected injector: Injector, protected cdr: ChangeDetectorRef) {
        super(cdr, injector);
    }

    ngOnInit() {
        super.ngOnInit();
    }
}

<mat-form-field [floatLabel]="floatLabel && 'always'" [appearance]="appearance">
    <mat-label *ngIf="label && floatLabel !== 'never'">{{ label | translate: translateParams }}</mat-label>
    <input
        #inputElement
        #input="ngForm"
        matInput
        label=""
        [type]="type"
        [attr.disabled]="disabled"
        [readonly]="disabled"
        [placeholder]="placeholder | translate: translateParams"
        [formControl]="control"
        [maxLength]="maxLength"
        [name]="name"
        [required]="required"/>
    <mat-icon *ngIf="icon" matPrefix color="primary">{{icon}}</mat-icon>
    <span *ngIf="suffix" matSuffix>{{suffix}}</span>
    <mat-error *ngIf="hasError('required')">{{ 'COMMON.REQUIRED' | translate: translateParams }}</mat-error>
    <mat-error *ngIf="hasError('max')">{{ 'ERROR.NUMERIC.MAX' | translate }}</mat-error>
    <mat-error *ngIf="hasError('min')">{{ 'ERROR.NUMERIC.MIN' | translate }}</mat-error>
</mat-form-field>
