Three useful Babel presets

As of version 6, Babel supports presets, sets of features that can be enabled together. This blog post looks at three new useful Babel presets (and, as a bonus, two presets especially for Node.js).

Complementing or replacing babel-preset-es2015

These two presets are useful complements to babel-preset-es2015 (for ES6):

Note that if you want all of ES2017 (as much as it is supported by Babel) then you need three presets: es2015, es2016 and es2017. Alternatively, there is also a meta-preset:

  • babel-preset-latest will always contain all the “yearly” presets. At the moment, those are: es2015, es2016 and es2017.

Bonus: minimal presets for Node.js

  • babel-preset-es2015-node replaces babel-preset-es2015. It checks the Node.js version and only enables plugins whose functionality is missing (not much in recent versions).

  • babel-preset-latest-minimal replaces babel-preset-latest. It determines what plugins are needed via feature detection. As the repository’s readme states: that only makes sense for Node.js, but not for browsers.
