Babel 6.x presets for Node 6.x
Based on Node.js v6.0.0
Babel 6.x is awesome, but simply including the ES2015 preset means you're transpiling features that your Node 6.x installation can already do faster and natively, replacing them with inferior / older code.
This preset complements existing V8-native functionality - it doesn't work around it.
The end result is nearly always a faster build and script execution time.
- Removes trailing commas from function calls (via babel-plugin-syntax-trailing-function-commas)
- CommonJS import/export module syntax (babel-plugin-transform-es2015-modules-commonjs)
Install via NPM the usual way:
npm i babel-preset-node6
.babelrc file in your project root, and include 'node5' in your preset path:
Now whenever you run
babel-node, it will polyfill your app with the remaining ES2015 features that Node 6 is missing.
$ babel script.js --presets node6
Via Node API
If you don't want to use a project-wide
.babelrc file (as above):
And if you do, and you want to use vanilla
node instead of
babel-node as your CLI, you can create an entry script that references your pre-transpiled code like so:
... which will then run everywhere Node can.
Of course, make sure to
npm i -S babel-core or
npm i -S babel-register respectively, to grab the NPM packages you'll need to transpile on-the-fly.
Webpack, Gulp, Browserify, etc
Follow vendor instructions and include
node6 in your babel "preset" list.
How to add React support
Babel has a ready-made preset for React, and you now need to install it separately.
Just grab it via NPM:
npm i babel-preset-react
And then add it to your "presets" list in
