AngularJS Question

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';

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.

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?


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.

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 )
