AngularJs 1.x upgrade, unexpected token : for a safe type

I'm working on angularjs from 1 to 2 upgrade tutorial (Angular 1 upgrade) and phonecat codebase example. After installing typescript and all mentioned dependencies adding a type :boolean for a function parameter input makes chrome fails the execution with "Uncaught SyntaxError: Unexpected token :" checkmarkFilterProvider consecutively is not created and fails the Provider injection into a component. 

(function() {
    ///<reference path='../../../typings/index.d.ts' />
    'use strict';

    angular.
        module('core').
        filter('checkmark', function() {
            return function(input:boolean) {
                return input ? '\u2713' : '\u2718';
            };
        });
})();

npm run tsc -w command compiles .ts files and creates maps, however, browser execution fails. enter image description here

In the end *.ts source files are compiled in a project explorer but browser doesn't have them as @tadwork pointed out. What is my configuration missing out?

Update

To run the angular app I execute npm start script from package.json that theoretically should compile *.ts files and run http-server with the ./app as a server source (see package.json scripts -> start).

./app folder after script execution has compiled *.js and *.map.js files. enter image description here

Solution

  • looks like the Typescript type annotations are getting injected into the browser without getting compiled so the types are still on the input parameter

    return function(input: boolean )
