Can you add also TypeScript examples on your AngularLiveLessons ?

I am enjoying a well presented video introduction to Angular. I'm completely new to Angular.

I am using Safaribooksonline.com video 20, 'Create a model for your recipe app'

The editor (in the video) contains a model folder which has recipe.ts
This is not present in my editor.

Is this due a different version of Angular?
How does the model folder get created?

I kind of liked having a default photo if none was added to a recipe, but still want to use the class binding that contains the img tag. I see that *ngIf can handle an if...else, but I cannot seem to get it to work. I tried:

Error:

EditNewRecipeComponent.html:31 ERROR Error: There is no FormControl instance attached to form control element with name: 'ingredient_0

how to create this error:
click add ingredients button.
click add ingredients button.
click remove the first ingredients button.
fill in the ingredients forms
