Full Page Scroll in Angular 12 App

Angular 12 full page scroll example tutorial; i am going to show you easy way how to implement full page scroll in angular 12 app using npm library.

The ngx-page-scroll is animated scrolling functionality for angular written in pure typescript with no additional dependencies.

The features of ngx-page-scroll-core are:

flexible: trigger scroll animations after component load, server response, etc.
easy-to-use directive: scroll to an element referenced in the href-attribute (href="#mytarget) just by adding pageScroll directive
customizable: adjust duration, offset or whether scrolling stops if the user interrupts (read more)
use custom easing functions to calculate the scroll position over time
works across routes (scrolls to target element as soon as the routing has finished) and in both directions (horizontal/vertical)

Angular 12 Full Page Scrolling Tutorial

Step 1 – Create New Angular App
Step 2 -Import Modules on Module.ts File
Step 3 – Add Code on View File
Step 4 – Add Code On Component ts File
Step 5 – Update CSS File
Step 6 – Start Angular App And PHP Server

Step 1 – Create New Angular App

First of all, open your terminal and execute the following command on it to install angular app:

ng new my-new-app

Then install NPM package called ngx-page-scroll-core to create full page scrolling. You can install the package by execute the following command on terminal:

npm i ngx-page-scroll-core

Step 2 -Import Modules on Module.ts File

Import modules; so go to src/app directory and open app.module.ts file. Then add the following code into it:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
 
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { NgxPageScrollCoreModule } from 'ngx-page-scroll-core';
 
@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    NgxPageScrollCoreModule.forRoot({duration: 500})
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Step 3 – Add Code on View File

Create html markup for full page scroll app. So, visit src/app/app.component.html and update the following code into it:

<div class="main-wrapper">
 
 
  <div class="step-container">
    <div class="step" [ngClass]="{'active': activeUIIndex === 1}" pageScroll (click)="scrollCustomImplementation(sec1, 1)">
      <div class="v-stepper">
        <div class="circle"></div>
        <div class="line"></div>
      </div>
    </div>
 
    <div class="step" [ngClass]="{'active': activeUIIndex === 2}" pageScroll (click)="scrollCustomImplementation(sec2, 2)">
      <div class="v-stepper">
        <div class="circle"></div>
        <div class="line"></div>
      </div>
    </div>
 
    <div class="step" [ngClass]="{'active': activeUIIndex === 3}" pageScroll (click)="scrollCustomImplementation(sec3, 3)">
      <div class="v-stepper">
        <div class="circle"></div>
        <div class="line"></div>
      </div>
    </div>
 
    <div class="step" [ngClass]="{'active': activeUIIndex === 4}" pageScroll (click)="scrollCustomImplementation(sec4, 4)">
      <div class="v-stepper">
        <div class="circle"></div>
        <div class="line"></div>
      </div>
    </div>
 
    <div class="step" [ngClass]="{'active': activeUIIndex === 5}" pageScroll (click)="scrollCustomImplementation(sec5, 5)">
      <div class="v-stepper">
        <div class="circle"></div>
      </div>
    </div>
 
  </div>
 
  <div #sec1 class="card-wrapper">
    <div class="card">
      <div class="card-container">
        <h4><b>John Doe 1</b></h4>
        <p>Architect & Engineer</p>
      </div>
    </div>
  </div>
 
<div #sec2 class="card-wrapper">
    <div class="card">
      <div class="container">
        <h4><b>John Doe 2</b></h4>
        <p>Architect & Engineer</p>
      </div>
    </div>
  </div>
 
  <div #sec3 class="card-wrapper">
    <div class="card">
      <div class="container">
        <h4><b>John Doe 3</b></h4>
        <p>Architect & Engineer</p>
      </div>
    </div>
  </div>
 
  <div #sec4 class="card-wrapper">
    <div class="card">
      <div class="container">
        <h4><b>John Doe 4</b></h4>
        <p>Architect & Engineer</p>
      </div>
    </div>
  </div>
 
  <div #sec5 class="card-wrapper">
    <div class="card">
      <div class="container">
        <h4><b>John Doe 5</b></h4>
        <p>Architect & Engineer</p>
      </div>
    </div>
  </div>
  
</div>

Step 4 – Add Code On Component ts File

Go to src/app directory and open app.component.ts. Then add the following code into component.ts file:

import { Component } from '@angular/core';
import { Inject } from '@angular/core';
import { DOCUMENT } from '@angular/common';
import { PageScrollService } from 'ngx-page-scroll-core';
 
@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss'],
})
export class AppComponent {
  title = 'Fullpage Scrolling';
  activeUIIndex = 1;
 
  constructor(private pageScrollService: PageScrollService, @Inject(DOCUMENT) private document: any) { }
 
  scrollCustomImplementation(element: HTMLElement, index) {
    this.pageScrollService.scroll({
      document: this.document,
      scrollTarget: element,
    });
    this.activeUIIndex = index;
  }
}

Step 5 – Update CSS File

Create styles for UI elements. And update the app.component.scss file with the following code:

.main-wrapper {
  text-align: center;
  height: 100vh;
  max-width: 650px;
  margin-left: auto;
  margin-right: auto;
}
 
// Card Styles
.card-wrapper {
    height: 100%;
}
.card {
  box-shadow: 0 4px 8px 0 rgba(0, 0, 0, 0.2);
  transition: 0.3s;
  height: 99%;
  margin: 5px;
  background: rgb(176, 218, 255);
}
.card:hover {
  box-shadow: 0 8px 16px 0 rgba(0, 0, 0, 0.2);
}
.card-container {
  padding: 2px 16px;
}
 
// Stepper Styles
.step-container {
  width: 30px;
  position: fixed; 
  top: 25%; 
  opacity: 0.5;
  transition: opacity 0.3s;
  -webkit-transition: opacity 0.3s;
}
.step-container:hover {
    opacity: 1;
}
.step {
  padding: 10px;
  display: flex;
  flex-direction: row;
  justify-content: flex-start;
  background-color: cream;
}
.v-stepper {
  position: relative;
}
.step .circle {
  background-color: white;
  border: 3px solid gray;
  border-radius: 100%;
  width: 15px;
  height: 15px;
  display: inline-block;
}
.step .line {
  top: 20px;
  left: 9px;
  height: 100%;
  position: absolute;
  border-left: 3px solid gray;
}
.step.completed .circle {
  visibility: visible;
  background-color: gray;
  border-color: rgb(0, 0, 0);
}
.step.completed .line {
  border-left: 3px solid rgb(0, 0, 0);
}
.step.active .circle {
  visibility: visible;
  border-color: rgb(0, 0, 0);
}
.step.empty .circle {
  visibility: hidden;
}
.step.empty .line {
  top: 0;
  height: 150%;
}
.step:last-child .line {
  border-left: 3px solid white;
  z-index: -1;
}

Step 6 – Start Angular App And PHP Server

Execute the following commands on terminal to start angular app:

ng serve
