babel/packages/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)

{
  "plugins": ["@babel/transform-object-assign"]
}

Via CLI

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

Via Node API

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