javascript - Closure compiler export Typescript classes and functions -

i trying use closure compiler advanced mode on typescript generated classes no success. there has accomplished such things.

typescript class

class testdata { blogname: string; cachetimeout: number; copyrightholder: string;  constructor(blogname: string, cachetimeout: number, copyrightholder: string) {     this.blogname = blogname;     this.cachetimeout = cachetimeout;     this.copyrightholder = copyrightholder; }  addblog(value: string): boolean {     console.log('add blog');     return true; }  validate(): boolean {     console.log('all valid');     return true }        }  var mytestdata = new testdata("name",22,"cpyright"); 

generated code

var testdata = (function () { function testdata(blogname, cachetimeout, copyrightholder) {     this.blogname = blogname;     this.cachetimeout = cachetimeout;     this.copyrightholder = copyrightholder; } testdata.prototype.addblog = function (value) {     console.log('add blog');     return true; }; testdata.prototype.validate = function () {     console.log('all valid');     return true; }; return testdata;  })();var mytestdata = new testdata(); 

this compiles

new function() {}; 

i understand should provide exports, added

window['testdata'] = testdata; window['testdata'].prototype['addblog'] = testdata.prototype.addblog window['testdata'].prototype['validate'] = testdata.prototype.validate 

my output closure compiler advanced compilation

var = function() {   function b() {   }   b.prototype.a = function() {     console.log("add blog");     return !0;   };   b.prototype.b = function() {     console.log("all valid");     return !0;   };   return b; }(); window.testdata = a; window.testdata.prototype.addblog = a.prototype.a; window.testdata.prototype.validate = a.prototype.b; new a; 

if see there still no constructor code left. gets worse when add inside module.

i tried use @export of google closure wiht no success

i see couple of pluggins can generate closure compiler annotations based on typescript, doesnt generate proper code.

thirdparty closure annotations generator

i ran basic test of this. perhaps changed code , haven't re-tried.

if compile typescript in question, should result in following javascript:

var testdata = (function () {     function testdata(blogname, cachetimeout, copyrightholder) {         this.blogname = blogname;         this.cachetimeout = cachetimeout;         this.copyrightholder = copyrightholder;     }     testdata.prototype.addblog = function (value) {         console.log('add blog');         return true;     };     testdata.prototype.validate = function () {         console.log('all valid');         return true;     };     return testdata; })(); var mytestdata = new testdata("name", 22, "cpyright"); 

in particular, last line passes arguments testdata constructor.

a quick run of results in (white-space mine) using @compilation_level simple_optimizations:

var testdata=function(){     function a(a,b,c){         this.blogname=a;this.cachetimeout=b;this.copyrightholder=c     }     a.prototype.addblog=function(a){console.log("add blog");return!0};     a.prototype.validate=function(){         console.log("all valid");return!0     };     return }(),mytestdata=new testdata("name",22,"cpyright"); 

if use advanced optimizations on partial code, aggressive. need supply all of code closure compiler understand isn't used.

if example represents of code, you'll notice constructor along 3 properties (blogname, cachetimeout, , copyrightholder) genuinely never used, can removed without affecting behaviour of program.
