I’m creating a project which uses SystemJS/JSPM.
I’m also using TypeScript.

Now TypeScript has the option of compiling JS using SystemJS Modules – which I’m doing and all is good. I’ve created TS modules and then imported modules from JSPM – at which point TS uses SystemJS to import those modules in Javascript.

Where I get confused is why SystemJS then also has the option of using TypeScript and/or Babel as a Transpiler.

Are there ready made JSPM/NPM modules out there that come in Typescript form or ES6 form that SystemJS would then use one of these Transpilers to build Javascript / or transpile down to ES5?

Or am I missing something entirely here?

As a side note there’s no systemjs tag or transpiler tag on programmers exchange.
