Angular ng.IComponentOptions binding directive list

I'm currently utilizing the ng.IComponentOptions to construct my component class which houses both my controller and view template:

export class LCAConfiguratiePersonenDetailComponent implements ng.IComponentOptions {
    public templateUrl: string;
    public controller: any;
    public bindings: any;

    public static IID: string = 'lcaConfiguratiePersonenDetail';

    constructor() {
        this.templateUrl = require('./LCAConfiguratiePersonenDetail.template.html');
        this.controller = LCAConfiguratiePersonenDetailComponentController;
        this.bindings = {
            id: '<'
        };
    }
}

The issue I'm encountering is my lack of understanding on what specific bindings I can implement and their exact functions. I've been referencing previous examples and testing out different options based on trial-and-error.
Could someone provide a comprehensive explanation on the various types of bindings available, or direct me to a resource where I can learn more about them?

I'm confident that the information exists, however, my search queries haven't led me to the right page that addresses my query.

Answer №1

When it comes to TypeScript transpiling into AngularJS code, a detailed explanation can be found by exploring the AngularJS 1.5 component guide.

It is recommended to use < and @ bindings for inputs. The < symbol indicates one-way bindings introduced in version 1.5. Unlike =, properties bound in the component scope are not actively monitored. This means that updating the property within the component scope will not automatically reflect in the parent scope. However, both scopes reference the same object, so modifications to object properties or array elements in the component will be reflected in the parent. It is generally advised not to modify object or array properties directly in the component scope. @ bindings are suitable when dealing with string inputs, particularly when the binding value remains constant.

bindings: {
    hero: '<',
    comment: '@'
}

For outputs, utilize & bindings which serve as callbacks to trigger component events.

bindings: {
    onDelete: '&',
    onUpdate: '&'
}
