A Powerful Tooltip and Popover for Angular Applications

Tippy.js is the complete tooltip, popover, dropdown, and menu solution for the web, powered by Popper.js.

It is an abstraction over Popper that provides the logic and optionally the styling involved in all types of elements that pop out from the flow of the document and get overlaid on top of the UI, positioned next to a reference element.

This is a lightweight wrapper with additional features that lets you use it declaratively in Angular. Tippy has virtually no restrictions over Popper and gives you limitless control while providing useful behavior and defaults.

If you're using v1 and don't want to migrate, you can find it here.

Features

✅ Position Tooltips, Menus, Dropdowns, and Popovers
✅ Predefined Variations
✅ TemplateRef/Component Support
✅ Lazy Registration
✅ Manual Trigger Support
✅ Text Overflow Support
✅ Context Menu Support

Installation

$ npm i @ngneat/helipopper
# Or if you're using yarn
$ yarn add @ngneat/helipopper
# Or if you're using pnpm
$ pnpm i @ngneat/helipopper

Configure it as shown below:

import { provideTippyLoader provideTippyConfig, tooltipVariation, popperVariation } from '@ngneat/helipopper/config';

bootstrapApplication(AppComponent, {
  providers: [
    provideTippyLoader(() => import('tippy.js')),
    provideTippyConfig({
      defaultVariation: 'tooltip',
      variations: {
        tooltip: tooltipVariation,
        popper: popperVariation,
      },
    }),
  ],
});

Please note that the provideTippyLoader is required, as it specifies how Tippy is loaded - either synchronously or asynchronously. When dynamic import is used, the library will load only when the first Tippy directive is rendered. If we want it to load synchronously, we use the following:

import tippy from 'tippy.js';

provideTippyLoader(() => tippy);

Add the styles you want to styles.scss:

@import 'tippy.js/dist/tippy.css';
@import 'tippy.js/themes/light.css';
@import 'tippy.js/animations/scale.css';

You have the freedom to customize it if you need to.

Import the standalone TippyDirective in your components:

import { TippyDirective } from '@ngneat/helipopper';

@Component({
  standalone: true,
  imports: [TippyDirective],
})
class ExampleComponent {}

And use it in your templates:

<button tp="Helpful Message">I have a tooltip</button>

The library exposes default variations for tooltip and popper. You can use them, extend them, or pass your own variations. A variation is a set of predefined tippy properties. For example, here's how the built-in tooltip variation looks like:

export const tooltipVariation = {
  theme: null,
  arrow: false,
  animation: 'scale',
  trigger: 'mouseenter',
  offset: [0, 5],
};

Use TemplateRef as content

<button [tp]="tpl" tpVariation="popper">Click Me</button>

<ng-template #tpl let-hide>
  <h6>Popover title</h6>
  <p>And here's some amazing content. It's very engaging. Right?</p>
</ng-template>

Use Component as content

import type { TippyInstance } from '@ngneat/helipopper/config';
import { injectTippyRef } from '@ngneat/helipopper';

@Component()
class MyComponent {
  tippy = injectTippyRef();
}

<button [tp]="MyComponent">Click Me</button>

Text Overflow

You can pass the onlyTextOverflow input to show the tooltip only when the host overflows its container:

<div style="max-width: 100px;" class="overflow-hidden flex">
  <p class="ellipsis" [tp]="text" tpPlacement="right" [tpOnlyTextOverflow]="true">
    {{ text }}
  </p>
</div>

Note: this feature is using ResizeObserver api.

You might have cases where the host has a static width and the content is dynamic. In this case, use the tpStaticWidthHost input with combination with tpOnlyTextOverflow:

<div style="max-width: 100px;" class="overflow-hidden flex">
  <p
    style="width: 100px"
    class="ellipsis"
    [tp]="dynamicText"
    tpPlacement="right"
    [tpOnlyTextOverflow]="true"
    tpStaticWidthHost
  >
    {{ dynamicText }}
  </p>
</div>

Note: when using tpStaticWidthHost you can't use tpUseTextContent, you need to explicitly pass the content to tp in order to trigger content change.

Use Text Content

You can instruct tippy to use the element textContent as the tooltip content:

<p tp tpUseTextContent>{{ text }}</p>

Lazy

You can pass the tpIsLazy input when you want to defer the creation of tippy only when the element is in the view:

<div *ngFor="let item of items" [tp]="item.label" [tpIsLazy]="true">{{ item.label }}</div>

Note that it's using IntersectionObserver api.

Context Menu

First, define the contextMenu variation:

import {
  popperVariation,
  tooltipVariation,
  provideTippyConfig,
  withContextMenuVariation,
} from '@ngneat/helipopper/config';

bootstrapApplication(AppComponent, {
  providers: [
    provideTippyConfig({
      defaultVariation: 'tooltip',
      variations: {
        tooltip: tooltipVariation,
        popper: popperVariation,
        contextMenu: withContextMenuVariation(popperVariation),
      },
    }),
  ],
});

Now you can use it in your template:

<ng-template #contextMenu let-hide let-item="data">
  <ul>
    <li (click)="copy(item); hide()">Copy</li>
    <li (click)="duplicate(item); hide()">Duplicate</li>
  </ul>
</ng-template>

<ul>
  <li
    *ngFor="let item of list"
    [tp]="contextMenu"
    [tpData]="item"
    tpVariation="contextMenu"
  >
    {{ item.label }}
  </li>
</ul>

Manual Trigger

<div tp="Helpful Message" tpTrigger="manual" #tooltip="tippy">Click Open to see me</div>

<button (click)="tooltip.show()">Open</button>
<button (click)="tooltip.hide()">Close</button>

Declarative show/hide

Use isVisible to trigger show and hide. Set trigger to manual.

<div tp="Helpful Message" tpTrigger="manual" [tpIsVisible]="visibility">
  Click Open to see me
</div>

<button (click)="visibility = true">Open</button>
<button (click)="visibility = false">Close</button>

Global Config

• You can pass any tippy option at global config level.
• beforeRender - Hook that'll be called before rendering the tooltip content ( applies only for string )

Create tippy Programmatically

import type { TippyInstance } from '@ngneat/helipopper/config';
import { TippyService } from '@ngneat/helipopper';

class Component {
  @ViewChild('inputName') inputName: ElementRef;
  tippy: TippyInstance;
  private tippyService = inject(TippyService);

  async show() {
    if (!this.tippy) {
      this.tippy = await firstValueFrom(
        this.tippyService.create(this.inputName, 'this field is required')
      );
    }

    this.tippy.show();
  }

  ngOnDestroy() {
    this.tippy?.destroy();
  }
}
