Package Exports

babel-preset-env
babel-preset-env/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (babel-preset-env) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

[WIP 0.0.0] babel-preset-env

Babel preset for all envs.

Install

$ npm install --save-dev babel-preset-env

Usage via `.babelrc`

Options

targets - an object of browsers/environment versions to support. The data for this is currently at: https://github.com/babel/babel-preset-env/blob/master/src/plugins.js (It would be nice to move this to use a data source like kangax.github.io/compat-table). And we would like help to make the data is correct!
loose - Enable "loose" transformations for any plugins in this preset that allow them (Disabled by default).
modules - Enable transformation of ES6 module syntax to another module type (Enabled by default to "commonjs").
- Can be false to not transform modules, or one of ["amd", "umd", "systemjs", "commonjs"]
