library6.26.0jsnpmunverified

Compile object rest and spread properties to ES5. This plugin transforms rest properties in destructuring patterns and spread properties in object literals, enabling use of these ES2018 features in older environments. Version 6.26.0 is the last v6 release, now deprecated in favor of @babel/plugin-proposal-object-rest-spread (Babel 7). The plugin uses Babel's extends helper by default, but can be configured to use Object.assign via the useBuiltIns option. It supports both CommonJS and AMD module formats.

Setup Babel plugin and demonstrate object rest & spread transformation.

// Install: npm install --save-dev babel-plugin-transform-object-rest-spread // .babelrc: { "plugins": ["transform-object-rest-spread"] } // Input: let { x, y, ...z } = { x: 1, y: 2, a: 3, b: 4 }; let n = { x, y, ...z }; console.log(x, y, z); // Output (with default helper): var _extends = require("babel-helper-define-polyfill-provider").default; // simplified var _obj = { x: 1, y: 2, a: 3, b: 4 }; var x = _obj.x; var y = _obj.y; var z = _objectWithoutProperties(_obj, ["x", "y"]); var n = _extends({ x: x, y: y }, z);

Known issues
deprecatedbabel-plugin-transform-object-rest-spread is deprecated since Babylon 7.0.0 (now @babel/parser). Use @babel/plugin-proposal-object-rest-spread or @babel/plugin-transform-object-rest-spread in Babel 7.
fix
Upgrade to @babel/plugin-proposal-object-rest-spread for Babel 7.
affects: >=6.0.0
breakingIn Babel 6, useBuiltIns: true generates Object.assign directly, but older browsers may lack it. Requires a polyfill like core-js.
fix
Include a polyfill for Object.assign when setting useBuiltIns: true.
affects: >=6.0.0
gotchaThe plugin does not support rest/spread in function parameters or JSX attributes; those require additional plugins.
fix
Use babel-plugin-transform-object-rest-spread only for object literals and destructuring; for function params use babel-plugin-transform-es2015-parameters.
affects: >=6.0.0
Errors
