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, ...z } = { 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, ...z };
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
z = { x, ...y };
Out
z = Object.assign({ x }, y);
