`Getting Started with TypeScript in an ASP.Net MVC Application`

`Getting Started with TypeScript in an ASP.Net MVC Application`

Due to certain reasons, we have decided to begin our project with TS rather than JS.

We are facing issues with the variables set in the MVC Views, which are established by the Model of each View.

For example, tes.cshtml:

@model Testmodel
<script>
  var test = {};
  var test.myProp = @Model.Testproperty;
<script>

However, I encountered an error in my test.ts when attempting to access the test variable because my TypeScript file is not aware of it.

Could this be a misunderstanding in the architecture? Is there a solution to this issue?

To be honest, we have approximately 100 variables defined or created in RazorViews, including many Resource Variables from our resx files that we may need for a JavaScript alert, for instance!

To centralize all your global declarations, it's recommended to create a definitions file. Here is an example:

declare interface SampleInterface{
    myProp:string;
    myFunc(someParameter:string):void;
}
declare var test:SampleInterface;
declare var someFunc: () => number;

To streamline your code, one approach is to bind all your variables to the Window object or even create a helper in TypeScript that can parse the Window.Variables and Window.ResxVariables as needed.

On the server-side, you'll want two dictionaries - Variables and ResxVariables - which could be made static within your base controller.

You'll then need methods to easily add variables to these dictionaries:

Variables.Add("Timezone", "GMT+2");

And

ResxVariables.Add("ExitAlert", "Please stay more");

These methods will be accessible in your controller actions, allowing you to also include model properties.

An HtmlHelper can assist in rendering these dictionaries as objects linked to the Window.

Additionally, consider implementing functionality to clear these dictionaries when rendering a new page or based on specific requirements.

In my experience using a similar setup, we maintained two dictionaries: GlobalVariables (which persisted across page changes) and PageVariables (which were cleared with each new page).
