Angular 2 (Angular 4) – Structural Directives
This video was meant to be about dynamic forms, however I changed it last minute as I thought that learning the built in Structural Directives first would be important before I start build a dynamic form.
There are 3 built in Structural Directives in Angular 2.
– *ngIf
– *ngFor
– ngSwitch
Along with the explanation of what these 3 can do for your HTML template files, I explain what the asterisks means for ngIf and ngFor and how behind the scenes the Angular 2 framework is using a template element tag to render the content inside of it.
We show that components inside of any of the directives specified above get destroyed an re-initialised, every time it is toggle to be hidden. This is something a lot of developers make mistakes on. I show you how you can hide components without destroying it by using simple attribute binding.
There is no github repo for this video. It’s pretty simple so just follow along.
