Tiny Angular library to create overlays for tooltips, modals, dropdowns, alerts, toastr, popovers, menus, and more
Demo and documentation
Installation
step 1: Install from npm or yarn
npm install toppy // or
yarn add toppystep 2: Import ToppyModule in your main module
import { ToppyModule } from 'toppy';
@NgModule({
declarations: [AppComponent],
imports: [BrowserModule, ToppyModule], // <==
bootstrap: [AppComponent]
})
export class AppModule {}step 3: Import Toppy service in your component
import { Toppy } from 'toppy'; // <==
@Component({
selector: 'app-root',
template: '<div #el>Click me</div>'
})
export class AppComponent {
@ViewChild('el', { read: ElementRef })
el: ElementRef;
constructor(private _toppy: Toppy) {}
ngOnInit() {
const position = new RelativePosition({
placement: OutsidePlacement.BOTTOM_LEFT,
src: this.el.nativeElement
});
this.overlay = this._toppy
.position(position)
.content('hello') // content
.create();
}
open() {
this.overlay.open();
}
close() {
this.overlay.close();
}
}Content
Toppy allows to use string, html, TemplateRef, Component as overlay content.
Plain text
this.overlay = this._toppy
.position(position)
.content(`some plain text content`) // simple text
.create();HTML content
this.overlay = this._toppy
.position(position)
.content(`<div>any HTML content</div>`, { hasHTML: true }) // html
.create();Using TemplateRef
<ng-template #tpl>Hello world!</ng-template>@ViewChild('tpl') tpl:TemplateRef<any>;
this.overlay = this._toppy
.position(position)
.content(this.tpl) // template ref
.create();Component
// host component
@Component({
template: '<div>Hello</div>'
})
export class HelloComponent {}this.overlay = this._toppy
.position(position)
.content(HelloComponent) // <==
.create();Dont forget to add host component in
entryComponentsin module
Positions
Position determines the location and size of the overlay. There are four positions:
Relative position
Overlay position that is relative to specific element. These are used in tooltips, popovers, dropdowns, menus
new RelativePosition({
src: HTMLElement, // target element
placement: OutsidePlacement, // location of the content
width: string | number, // content width eg, `auto`, 150, `30%`
height: string | number, // content height eg, `auto`, 150, `30%`
autoUpdate: boolean // update position when window scroll/resize/drag
});Relative position supports 12 placements:
OutsidePlacement.BOTTOM;
OutsidePlacement.BOTTOM_LEFT;
OutsidePlacement.BOTTOM_RIGHT;
OutsidePlacement.LEFT;
OutsidePlacement.LEFT_BOTTOM;
OutsidePlacement.LEFT_TOP;
OutsidePlacement.RIGHT;
OutsidePlacement.RIGHT_BOTTOM;
OutsidePlacement.RIGHT_TOP;
OutsidePlacement.TOP;
OutsidePlacement.TOP_LEFT;
OutsidePlacement.TOP_RIGHT;Global position
Overlay position that is relative to window viewport. These are used in modals, alerts, toastr
new GlobalPosition({
placement: InsidePlacement, // location of the content.
width: string | number, // content width eg, `auto`, `150`, `30%`
height: string | number, //content height eg, `auto`, 150, `30%`
offset: number // oustide space of the content, in px
});Global position supports 9 placements:
InsidePlacement.BOTTOM;
InsidePlacement.BOTTOM_LEFT;
InsidePlacement.BOTTOM_RIGHT;
InsidePlacement.LEFT;
InsidePlacement.RIGHT;
InsidePlacement.TOP;
InsidePlacement.TOP_LEFT;
InsidePlacement.TOP_RIGHT;
InsidePlacement.CENTER;Slide position
Overlay position that is relative to window viewport. These are used in side panels, sidebars, blade
new SlidePosition({
placement: SlidePlacement, // rigth or left
width: string // width eg, '300px' or '30%'
});Slide position supports 2 placements:
SlidePlacement.LEFT;
SlidePlacement.RIGHT;Fullscreen position
Overlay that occupies complete size of the viewport.

Component communication
Component Data
When you host a component, you can control the overlay through ToppyOverlay service. Using this service you can access all properties that is provided in content. Also the properties comes with close.
this.overlay = this._toppy
.position(position)
.content(HelloComponent, { propName: 'toppy-test-prop' })
.create();
this.overlay.listen('t_compins').subscribe(comp => {
console.log('component is ready!', comp); // returns HelloComponent
});// host component
@Component({
template: '<div>Some text</div>'
})
export class HelloComponent {
constructor(public overlay: ToppyOverlay) {
console.log(this.overlay.props.propName); // will return 'toppy-test-prop'
}
close() {
this.overlay.close();
}
}Template Data
This is very similar to above one. When you use template as a content, you can pass additional data to it.
this.overlay = this._toppy
.position(position)
.content(template, { name: 'Johny' })
.create();Then in your template you can refer the data like this,
<ng-template #tpl let-toppy>
<div>Hello <span [innerText]="toppy.name"></span> !</div>
<button (click)="toppy.close()">Close</button>
</ng-template>Method close is automatically binded.
Plain text
When you use Plain text as a content, optionally you can able to set a class name to that div block.
this.overlay = this._toppy
.position(position)
.content('some content', { class: 'tooltip' })
.create();API
