We often need to pass a parameter like an ID to a route and then access that ID in order to call an API to get some data. In this article, we'll look at how to define a route with a parameter, how to use params with the routerLink directive, and how to use the route snapshot to use a param in a component. We'll also learn about subscribing to…
Read →Once routing is set up, we can add a new route by adding a new component and adding a path to our routes array in app.module.ts . But how do we navigate between the two routes? In this lesson of Angular Basics, I'll show you how to use routerLink to switch between the routes without causing the page to refresh. Here's the video lesson: Add a New…

I reprised a talk I gave last year for the ngPittsburgh meetup group called "Finding the Right Path from AngularJS to Angular" that goes over a decision tree you can use to determine this. Here's the recording: You can also watch the…
Read →One of the things that drove me crazy when I was first learning RxJS in Angular was how difficult it seemed to reload a collection of data after I added or deleted an item. With promises, I could just use .then() and be on my way. What do we do with observables? Should we just nest another subscription? Even if we do that, since we're using the…
