What would be the effort needed for having type completion in html files.

I understand that this question is related to specific frameworks used in the editor in conjunction with typescript (e.g. angular2, aurelia, ...)
So, let's focus on a case where a viewModel (a .ts) goes together with a view (a .html).
the viewModel is a typescript class and contains a definition for 'Customer' having firstName and lastName props.
When creating the view, I would like to have type completion on the specific bind statement (so, in the example here on the string inside value.bind.

///////here some magic to 'bind' the view to the viewModel with respect to type completion
<div class="col-sm-10">
<input type="text" placeholder="First Name"  class="form-control"
value.bind="customer.firstName" />
</div>

The above example is aurelia, but similar stuff can happen in other frameworks.
I think I saw similar things in visual studio in asp.net MVC.
How realistically would it be to make this happen also for sublimeText ?
Thanks.

No files, tests, or entry points are named. Start by defining the supported HTML binding syntax and framework scope, then assess how a TypeScript viewModel could be associated with an HTML view; done would be a documented feasibility decision and implementation scope.
