Easiest way to experiment with `import` ES6

The recent Meteor tutorials use the import aspect of ES6 a lot, and I'd like to know if there's an es6 wrapper or other simple way to experiment with this specific feature without having to create a new package.json, npm install babel --save, npm start, etc...

Ideally, something like this:

> echo 'import "./importme.js";' > new.js
> echo 'console.log('hi');'      > import.js
> es6 new.js
hi
>

I did notice babel-node, but it's complaining that import is not a valid token, and apparently it doesn't support import from the REPL.

Is there a REPL or node wrapper that supports import?

Thanks

babel-node will work fine, but babel doesn't do anything out of the box since version 6. You have to install presets to opt-in to the new features.

  1. npm install babel-node
  2. npm install babel-preset-es2015 Installs the preset for ES2015 syntax.
  3. touch .babelrc Create a .babelrc file to tell babel which presets you are using

Inside your .babelrc file, add the following code:

{
  "presets": ["es2015"]
}

Now, running babel-node will work.

I believe that there is not, in fact, a simpler and more maintainable way than what is presented in the Babel 6 manual. It is not too hard. See https://babeljs.io/docs/setup/#installation
