Cannot read property of undefined angular2 ngif

Question

I am now able to get the object in the view however I cannot run an if statement. Per previous answer this is how I am bringing in the object.

public getPos         


        

Answer 1

The cart object is null until the service getPosts$ returns (callback). Therefore, the code *ngIf="cart.vegetable ... is equal to *ngIf="null.vegetable ... until that happens. That is what is happening.

What you could do is put a DOM element with *ngIf="cart" containing the other *ngIf. For example:

    
{{cart.vegetable}}

*Edit: As it is said in the next answer, a good alternative (and good practice) is the following:

{{cart.vegetable}}
