Angular 2 Ahead-of-Time compiler: must I make all class properties public?

Question

Angular 2 rc 6, typescript 2, node 4.5.0, npm 2.15.9 on Windows 7

I\'m trying to move from Just-in-T

Answer 1

So is too, in Final release of Angular 2 whit Ionic2 RC1

A workaround for Fields could be to use getters without setters

protected _myField: any;

get myField(): any { 
  return this._myField; 
}

You can also see other JiT to AoT considerations to adapt your code in this blog of Isaac Mann

1. const lambda => export function
2. default export => named export
3. private, protected accessors should be changed to public for any members accessed from template
4. dynamic component template => static template
5. moduleId should be set on components with templateUrl

Answer 2

For a given component all its members (methods, properties) accessed by its template must be public in the ahead-of-time compilation scenario. This is due to the fact that a template is turned into a TS class. A generated class and a component are 2 separate classes now and you can't access private members cross-class.

In short: you can't access private members in your templates if you want to use ahead-of-time compilation.
