When navigating between routes in an Angular application, the browser's scroll position is often reset to the top of the page. This can be frustrating for users who want to maintain their scroll position between route changes. In this article, we'll explore how to prevent scrolling with navigation in Angular components.

Steps To Prevent Scrolling with Navigation

Step 1: Install Angular CLI

If you haven't installed Angular CLI yet, install it using the following command

npm install -g @angular/cli

Step 2: Create a New Angular Project

ng new prevent-scroll-app
cd prevent-scroll-app

Step 3: Generate Components

 ng generate component home
ng generate component about

  AngularJS is a popular open-source framework that simplifies web development
  by creating interactive single-page applications (SPAs). Unlike traditional
  websites that load new pages for each click, SPAs offer a smoother user
  experience by updating content on the same page. AngularJS makes this possible
  by transforming static HTML into dynamic content that adapts to user
  interactions. Features like data binding and dependency injection streamline
  development, saving you time and effort. With regular updates and a large
  community, AngularJS ensures your web applications stay modern and efficient.
