ionic-5-header-parallax v1.2.4

Parallax Header Directive for Ionic v5

This directive enables parallax effect on ion-header elements to display a cover photo while on top of the page and transition it to the normal navbar when content is scrolled down.

Set Up

1. Install package: $ npm i ionic-5-header-parallax.
2. Import the directive into your desired module (usually appmodule.ts):

import { IonicHeaderParallaxModule } from 'ionic-5-header-parallax';

@NgModule({
  imports: [
    IonicHeaderParallaxModule,
    ...

Usage

Just add the attribute parallax to any <ion-header> element:

<ion-header parallax></ion-header>

Optional attributes:

• imageUrl (string): The background image to show while expanded.
• maximumHeight (number): The height for the header when expanded. Default is 200.
• expandedColor (string): The color (web hex formatted) to show while the header is expanded when no imageUrl is set. When scrolled it will fade to the navbar/toolbar's color or the one configured in <toolbar color=""> attribute.
• titleColor (string): The text color (web hex formatted) for <ion-title> and <ion-back-button> elements when expanded. They will turn to their default color on cover collapse.

Example:

<ion-header parallax imageUrl="https://picsum.photos/350" maximumHeight="350" expandedColor="#AAA" titleColor="white">

  <ion-toolbar color="primary">
    <ion-title>
      Parallax Header
    </ion-title>
  </ion-toolbar>
</ion-header>

<ion-content>
	Some content here
</ion-content>

Modifying the Source Code / Contributing

I don't plan to be maintaining this package full-time, but as I'm usually developing in Ionic I'll be glad to update it any time I make some upgrades for myself. Contributions are very welcome. Find the instructions in the CONTRIBUTING.md file.

Feel free to improve the code!
