babel-plugin-transform-object-assign

babel-plugin-transform-object-assign

Replace Object.assign with an inline helper. If you are authoring an application, rather than a library, it is recommended that you use the Object.assign polyfill instead.

Example

In

Object.assign(a, b);

Out

var _extends = ...;
 
_extends(a, b);

Caveats

  • Will only work with code of the form Object.assign or Object['assign']. The following patterns are not supported:

    var { assign } = Object;
    var assign = Object.assign;

Installation

npm install --save-dev babel-plugin-transform-object-assign

Usage

Via .babelrc (Recommended)

.babelrc

{
  "plugins": ["transform-object-assign"]
}

Via CLI

babel --plugins transform-object-assign script.js

Via Node API

require("babel-core").transform("code", {
  plugins: ["transform-object-assign"]
});
