    babel-plugin-transform-object-rest-spread

    This plugin allows Babel to transform rest properties for object destructuring assignment and spread properties for object literals.

    Example

    Rest Properties

    let { x, y, ...} = { x: 1, y: 2, a: 3, b: 4 };
    console.log(x); // 1
    console.log(y); // 2
    console.log(z); // { a: 3, b: 4 }

    Spread Properties

    let n = { x, y, ...};
    console.log(n); // { x: 1, y: 2, a: 3, b: 4 }

    Installation

    npm install --save-dev babel-plugin-transform-object-rest-spread

    Usage

    Via .babelrc (Recommended)

    .babelrc

    {
      "plugins": ["transform-object-rest-spread"]
    }

    Via CLI

    babel --plugins transform-object-rest-spread script.js

    Via Node API

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

    Options

    useBuiltIns

    boolean, defaults to false.

    By default, this plugin uses Babel's extends helper which polyfills Object.assign. Enabling this option will use Object.assign directly.

    .babelrc

    {
      "plugins": [
        ["transform-object-rest-spread", { "useBuiltIns": true }]
      ]
    }

    In

    = { x, ...};

    Out

    = Object.assign({ x }, y);
