About

This minimalistic Angular directive, free from external dependencies, empowers you to effortlessly implement CSS animations on elements. These animations trigger when an element comes into view through scrolling on the page. It seamlessly integrates with your choice of CSS animations.

Getting started

Installation

npm install ngx-scroll-animations

Optionally include prebuilt animations

/* angular-cli file: src/styles.css */
@import "node_modules/ngx-scroll-animations/styles/animations.min.css";

Import the directive

import { Component } from '@angular/core';
import { NgxScrollAnimationsDirective } from 'ngx-scroll-animations';

@Component({
  selector: 'app-root',
  standalone: true,
  templateUrl: './app.component.html',
  styleUrl: './app.component.scss',
  imports: [ NgxScrollAnimationsDirective ],
})
export class AppComponent {}

Add provideNgxScrollAnimations to your app.config.ts file as shown below.

export const appConfig: ApplicationConfig = {
  providers: [
    provideRouter(routes),
    provideClientHydration(),

    /// Add the code below
    provideNgxScrollAnimations({
      speed: 300,
      animationName: 'fade-in-up',
      once: false,
      /// Other configs...
    }),
  ],
};
