Components & services
BaseComponent
A base component adds the following features to a component:
EventAggregator
to send and receive events.I18N
to translate the page.Aware
to listen to events from other components.AntiBounce
to prevent multiple clicks on a button.Store
to store data in memory.Slots
informations to manage slots.
import { customElement, IContainer, inject } from 'aurelia';
import { BaseComponent } from '@aegenet/au2-base-component';
import template from './demo-component.html';
@customElement({
name: 'demo-component',
template,
})
@inject(Element, IContainer)
export class DemoComponent extends BaseComponent {
//
}
BasePage
A base page adds the following features to a page component:
Router
to navigate between pages.EventAggregator
to send and receive events.I18N
to translate the page.Aware
to listen to events from other components.AntiBounce
to prevent multiple clicks on a button.Store
to store data in memory.
import { IContainer, customElement, inject } from 'aurelia';
import { BasePage } from '@aegenet/au2-base-component';
import template from './demo-page.html';
@customElement({
name: 'demo-page',
template,
})
@inject(IContainer)
export class DemoPage extends BasePage {
//
}
Aware
When a component inherits from BaseComponent
, it can be controlled by events.
From TypeScript: with a simple IEventAggregator
, you can send events to the component.
import { IEventAggregator } from 'aurelia';
// [...]
const ev: IEventAggregator = container.get(IEventAggregator);
ev.publish('demo-component:tab1', { property: 'select', value: ['two'] });
From HTML: with the aware-component
custom element, you can send events to the component.
<demo-component component.ref="demoComponent" event-name="tab1">
<span slot="one" title="French">
<h5>Second slide label</h5>
<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</p>
</span>
<span slot="two" title="English">
<h5>Third slide label</h5>
<p>Praesent commodo cursus magna, vel scelerisque nisl consectetur.</p>
</span>
</demo-component>
<aware-component component.ref="awareBtnRef" events.bind="[{ name: 'demo-component:tab1', options: { property: 'select', value: ['two'] } }]"></aware-component>
<button click.trigger="awareBtnRef.publish()">Send event</button>
Store
This basic store is more like a cache system. It allows you to store data in memory and refresh it when needed.
import { DIStoreService, IStoreService } from '@aegenet/au2-base-component';
const storeService = container.get<IStoreService>(DIStoreService);
// Setup
storeService.setStore({
key: 'user',
async load(container) {
return JSON.parse(localStorage.getItem('user') || '[]');
},
}, {
key: 'user_index',
async load(container) {
return arrayToObject((await storeService.getStore('user')) as unknown[], 'id');
},
});
// [...]
// Get
await storeService.getStore('user'); // []
// Set
localStorage.setItem('user', JSON.stringify([{ id: 1, name: 'John' }]));
// Refresh
await storeService.refreshStore('user');
// Get
await storeService.getStore('user'); // [{ id: 1, name: 'John' }];
Container stats & debug
import { debugContainer } from '@aegenet/au2-base-component';
debugContainer(null);
/* {
instance: [],
singleton: [],
transient: [],
callback: [],
array: [],
alias: [],
} */
// container: IContainer;
debugContainer(container);
Default capture
<button
...$attrs
type="button"
click.trigger="doAction()"
<au-slot>
</au-slot>
</button>
import { customElement, IContainer, inject } from 'aurelia';
import { defaultCapture, BaseComponent } from '../src';
import template from './demo-default-capture.html';
/**
* Demo default capture
*/
@customElement({
name: 'demo-default-capture',
template,
capture: defaultCapture,
})
@inject(Element, IContainer)
export class DemoDefaultCapture extends BaseComponent {
public clickCount: number = 0;
constructor(element: Element, container: IContainer) {
super(element, container);
}
public doAction(): void {
this.clickCount++;
}
}
