In this post, I'm developing a data loading mechanism for Angular which can be configured to decide how to select, paginate and filter data from an in-memory cache or to load the data from the server for each page/filter change.
Creating a reusable table component in Angular
Here I'm introducing a reusable table component which can be reused to render a variety of data in a consistent manner without duplicating code. It interacts with the host component via a few property and event bindings
Angular ng-template to inject content into other components
View components sometimes need to have similar appearance but slightly different content and functionality. In this post, we're exploring how to use the same component but change out the link destinations of a list of links.
