How to append file extensions .js to typescript?

Question

In typescript I write the path without the extension -

import SomeClass from './some-class';  

How to make after compilation, these paths contain an extension .js ? Builds the project using gulp-typescript.

Answer 1

these paths contain an extension .js

You don't need to. Runtime systems (e.g. node, requirejs, systemjs) automatically assume a .js extension if you require a js file.
