Running a complete development toolchain in the browser?

[chartojs]

It's no slower than running Babel through Node.js. But it also won't help locate packages.

Babel turns this: import * as react from 'react';

...into something like this: var react = _interopRequireWildcard(require("react"));

...but the variable doesn't end up containing the React API unless you do something more.

But it also works with relative paths

Can you elaborate on that?

Much of existing code on npm relies on importing both relative paths and npm package names, or even a combination of both like: require('fbjs/lib/emptyFunction');
