Adding Preloaders to Components
Explore how to integrate ngx-spinner preloaders into Angular components to display loading animations during data fetches. This lesson guides you through importing the package, configuring it in your project, and implementing it in multiple components to enhance user experience during asynchronous operations.
Introduction to ngx-spinner
While building a web application, we’ll encounter scenarios where we have to fetch data from a back-end resource. This process is asynchronous in nature, making it necessary to use a preloader. A preloader is a static picture or animated figure displayed on the browser while an application is loading in the background. The preloader disappears once the data fetched on the application is ready.
In this project, we’ll use the npm package called ngx-spinner to set up our preloader. The ngx-spinner is an npm package well suited for Angular, and it has features such as the following:
- Configuration option through service injection
- Full screen mode (optional)
