Extensions

Slicky can be extended with extensions (sometimes referred to as modules, plugins or eg. bundles).

import {AbstractExtension} from 'slicky/extensions';

class MyOwnExtension extends AbstractExtension
{

    public getServices()
    {
        return [
            MyOwnService,
        ];
    }
    
    public getFilters()
    {
        return [
            MyOwnFilter,
        ];
    }
    
    public getDirectives()
    {
        return [
            MyOwnDirective,
        ];
    }

}

application.addExtension(new MyOwnExtension);

Application.addExtension must be called before Application.run

Methods

• getServices(): returns list of new services, same like in provide method
• getFilters(): returns list of new filters
• getDirectives(): returns list of new directives

Hooks

Extensions can be used also to alter default behaviour of internal parts of slicky with hooks.

doUpdateComponentServices(template: AbstractComponentTemplate, el: ElementRef, services: Array<CustomServiceDefinition>)

Changes list of additional services automatically passed into new components. This is useful when you want to pass different services into each component.

class ComponentExtension extends AbstractExtension
{

    public doUpdateComponentServices(template: AbstractComponentTemplate, el: ElementRef, services: Array<CustomServiceDefinition>): void
    {
        services.push({
            service: ComponentService,
            options: {
                useFactory: () => new ComponentService(template, el),
            },
        });
    }

}
