ngx-loading-bar

ng2-loading-bar is a visual component for Angular web apps that shows a thin progress bar at the top of the page while content is loading. If you've ever watched a slim colored stripe crawl across the top of a webpage while waiting for it to open, this project helps you build exactly that experience.

After installing the package, a developer drops the loading bar component near the top of their page layout. They can customize basic properties like the bar's color, height, and how fast the animation moves. Behind the scenes, the component pairs with a service that lets the app programmatically control the bar — starting, stopping, resetting, or marking it complete whenever the underlying data is ready. This means the bar doesn't just animate on its own; the application tells it when to start and finish based on real events like a data fetch finishing.

Someone building an Angular application who wants to give users visual feedback during slow page loads would use this. For example, if your app pulls in a lot of data or images and the screen feels frozen for a few seconds, adding this bar reassures users that something is happening and the page hasn't crashed. It's a small touch that makes an app feel more responsive and polished without requiring much effort.

One notable thing: the project explicitly states it is for demonstration purposes and is not maintained. Anyone wanting to use it would need to fork the repository and maintain their own version rather than relying on the original author for updates or bug fixes.
