Is it possible to utilize TypeScript for enforcing type safety in AngularJS templates?

Is it possible to utilize TypeScript in Angular 1.6 templates, following best practices such as components/bind-to-controller usage?

Consider the following template code:

<div>{{$ctrl.children[0].name}}</div>

If we know the type of the controller ($ctrl), can TypeScript aid in detecting errors such as:

  • 'children' not existing on $ctrl
  • 'children' not being an array
  • items in 'children' lacking a 'name' property (and so on)?

It would be helpful to have code completion in VS Code as well.

I've come across the following issues:

However, it's unclear how things stand in the AngularJS 1.x world based on these problems.

Answer №1

Negative.

AngularJs templates are dynamically interpreted, lacking a compilation process that would facilitate such verifications.

Answer №2

Instead of starting with AngularJS components, you have the option to begin with Angular 2 components and later convert them to AngularJS using the

@angular/upgrade/static::downgradeComponent
method. Check out the downgradeComponent documentation for more information.
