How to Handle Errors Globally in Angular – The Info Grid

In this post, I will show you how to intercept the default error handler, and then send the errors to a remote logging service (Simple REST API call) and show a friendly message to the user. Then, we need to add an handleError method in our class, which will catch the errors in our app and do something with the errors. One option would be sending it to a remote logging server such as AWS Cloud Watch and provide a custom error message to the user. Continue reading

Web-components like AngularJS directives

As you may already know web components consist out of a set of technologies which are combined to create a custom element for use in your HTML markup. This is because these lines will be where we’ll add our logic to turn this normal directive in to the essence of a true web component. This effectively wraps the markup inside a Template for later use with the shadow root whilst still maintaining a link inside it with our transcluded content through the content tag. Continue reading

What is `forwardRef` in Angular and why we need it – Angular In Depth

Usage example
Angular documentation shows the following example:
class Door {
lock: Lock;

// Door attempts to inject Lock,
// despite it not being defined yet. So, for example, if you want to access the form directive associated with the input in your custom directive you can do like this:
@Directive({
selector: '[mycustom]'
})
export class MyCustom {
constructor(@Inject(NgControl) directive) {…input type="text" ngModel mycustomTo enable that each both NgModel and formControl directives define a formControlBinding provider and register it in the directive decorator descriptor. Here is how the formControl directive does that:
export const formControlBinding: any = {
provide: NgControl,
useExisting: selector: '[formControl]',
providers: [formControlBinding],

})

export class FormControlDirective { … }and NgModel directive:
export const formControlBinding: any = {
provide: NgControl,
useExisting: NgModel
};@Directive({
selector: '[ngModel]',
providers: [formControlBinding],

})
export class NgModel { … }The interesting piece of the implementation here is that formControlBinding is defined outside the directive class decorator. Continue reading
