You can use node specific preset like other's have mentioned but working on https://github.com/babel/babel-preset-env for all future versions as well

You want the babel-preset-latest-minimal package.
Does exactly that - feature based Babel transforms
There have been presets for Node 4, Node 5, etc so I imagine there will be one for v7 once it's released.
Also, does anyone know if there is a way to get babel to output code targeting Node v7? Like, just stuff in the 'latest' preset that isn't out-of-the-box (with or without the flag).
