I started to programming typescript, but I need some node_modules, that are only in javascript. (@typings/... not working here).

So, how could I generate from these packages to typescript compatible package?

Because import 'package-name' from 'package-name'; not working in .ts files. (Err message: Cannot find module). I would like to import like a module, not a file. So I do not want to use this format:

import 'package-name' from '../node_modules/package-name/src/package-name.js';

In addition, I use SystemJs to load other js files. So I am confusing about this:

When I have to use SystemJs?
When I have to use TypeScript import statement?
Do I have to generate from js to ts everytime or only special cases?

Thanks for the help

You need to write `.d.ts` files by hand. – SLaks Apr 20 '17 at 20:02
Could you show me an example or a link, especially from node_module? – ktom Apr 20 '17 at 20:03
