Angular 2 (Angular 4) – Lifecycle Hooks – AfterContentInit, AfterContentChecked

In this video I introduce 2 more hooks that angular components can use. AfterContentInit and AfterContentChecked. These lifecycle hooks are only useful in situations where you require some content to be projected into your component from someone using your component.

I look at how these lifecycle hooks are called, as well as look at how to access child content inside of your template by using just the ContentChild decorator or the ContentChildren decorator with a QueryList.

To follow along with this tutorial please clone down the following branch, then checkout the tutorial16 branch. If you wish to see the final result, check out the tutorial19 branch.

This is a challenging subject so please take your time to understand these hooks and what they are useful for.
