TypeScript static classes

Question

I wanted to move to TypeScript from traditional JS because I like the C#-like syntax. My problem is that I can\'t find out how to declare static classes in TypeScript.

Answer 1

One possible way to achieve this is to have static instances of a class within another class. For example:

class SystemParams
{
  pageWidth:  number = 8270;
  pageHeight: number = 11690;  
}

class DocLevelParams
{
  totalPages: number = 0;
}

class Wrapper
{ 
  static System: SystemParams = new SystemParams();
  static DocLevel: DocLevelParams = new DocLevelParams();
}

Then parameters can be accessed using Wrapper, without having to declare an instance of it. For example:

Wrapper.System.pageWidth = 1234;
Wrapper.DocLevel.totalPages = 10;

So you get the benefits of the JavaScript type object (as described in the original question) but with the benefits of being able to add the TypeScript typing. Additionally, it avoids having to add 'static' in front of all the parameters in the class.
