Angular applications are known for their rich features and robust performance. However, handling heavy computations or complex tasks on the main thread can degrade performance, leading to a sluggish user experience. To address this, Angular developers can harness the power of Web Workers. Web Workers run scripts in background threads, enabling smooth, responsive user interfaces.…
In Angular, change detection is crucial for synchronizing the application’s view with the data model. However, automatic change detection can cause performance issues, particularly during heavy computations or when interfacing with external libraries. To optimize performance in such cases, Angular offers the runOutsideAngular method. This blog post explores runOutsideAngular, explains its usage, and provides a…
In Angular, handling changes in input properties is crucial for creating dynamic and responsive components. The SimpleChange class facilitates this process by providing a way to detect and respond to changes in input properties. This blog post will explore SimpleChange, its usage, and provide a sample code example to illustrate its application. What is…
Angular, a robust framework for building dynamic web applications, offers developers a range of lifecycle hooks that provide valuable insights into the lifecycle hooks of Angular components. These hooks enable developers to execute custom logic at specific stages of a component’s lifecycle, enhancing control and flexibility. Let’s explore how you can utilize Angular lifecycle hooks…
Angular, a powerful framework for building web applications, comes with a robust routing module that allows developers to create dynamic, single-page applications (SPAs) with ease. The Router Outlet, one of the key components of Angular routing, serves as a placeholder that renders the routed component based on the current URL. Let’s delve into how Router…
Angular is a powerful framework for building dynamic web applications, and one of its key features is its built-in routing system. Angular’s routing module allows developers to navigate between different views or components within a single-page application (SPA) without the need for page reloads. Let’s explore how Angular routing works and how you can implement…
