Advanced

In this video #tutorial we will have a look at an advanced angular design pattern - forRoot() / forChild(). We will see what kind of problems it used to solve many years ago and how we can use it today in order to configure Angular modules. Besides this we will have a look at source code of Angular and check how Angular team used this pattern for RouterModule. I hope you will find something interesting from this video and I am looking forward for your feedback. Enjoy watching!
