babel-preset-es2015-node6

0.4.0 verified Sat Apr 25 auth: no javascript deprecated

Babel preset that enables ES2015 features missing from Node.js 6, such as ES modules compilation via transform-es2015-modules-commonjs. Version 0.4.0 is the latest stable release; the package is no longer actively maintained and was effectively superseded by @babel/preset-env. Unlike broader presets (e.g., babel-preset-es2015), this preset targets only Node.js 6, resulting in a smaller transform set. It supports a 'loose' option and a 'funcName' flag for Node.js < 6.5. No longer needed for modern Node.js versions.

Common errors

error Requires Babel "^6.0.0-0", but was loaded with "7.x.x" ↓

cause Babel 7 is incompatible with Babel 6 presets/plugins.

fix

Use @babel/preset-env instead, or downgrade to Babel 6.

error Error: Cannot find module 'babel-preset-es2015-node6' ↓

cause The preset is not installed or not in node_modules.

fix

Run npm install --save-dev babel-preset-es2015-node6.

Warnings

deprecated babel-preset-es2015-node6 is deprecated. Use @babel/preset-env with targets.node: '6' instead. ↓

fix Replace with @babel/preset-env: npm install --save-dev @babel/preset-env and configure targets: { node: '6' }.

breaking The 'object-rest' sub-preset is required for object-rest-spread; using the base preset may fail on destructuring and rest parameters. ↓

fix Use preset 'es2015-node6/object-rest' instead of 'es2015-node6' if you need object rest/spread.

gotcha If Node.js version is less than 6.5, automatic function name transformation is not enabled by default; code relying on function.name may break. ↓

fix Enable the 'funcName' option: { presets: [['es2015-node6', { funcName: true }]] }.

deprecated This preset only targets Node.js 6; it will not be updated for newer Node versions. ↓

fix Upgrade to @babel/preset-env for broader Node.js support.

Install

npm install babel-preset-es2015-node6

yarn add babel-preset-es2015-node6

Imports

default preset (es2015-node6)
wrong
```
module.exports = { presets: ['babel-preset-es2015-node6'] }
```
correct
```
module.exports = { presets: ['es2015-node6'] }
```
When specifying presets in .babelrc or babel config, omit the 'babel-preset-' prefix.

loose option

wrong

{ presets: ['es2015-node6', { loose: true }] }

correct

{ presets: [['es2015-node6', { loose: true }]] }

The options object must be wrapped in an array with the preset name.

object-rest variant
wrong
```
{ presets: ['es2015-node6'] }
```
correct
```
{ presets: ['es2015-node6/object-rest'] }
```
Use 'es2015-node6/object-rest' if you need object-rest-spread support, otherwise destructuring and parameters may fail.

Quickstart

Shows how to install the preset, configure Babel, and transform an ES2015 module file for Node.js 6.

// Step 1: Install dependencies
// npm install --save-dev babel-cli babel-preset-es2015-node6

// Step 2: Create .babelrc
// {
//   "presets": ["es2015-node6"]
// }

// Step 3: Transform a file
// npx babel script.js --out-file script-compiled.js

// Example ES2015 code to transform
import path from 'path';
const greet = (name) => `Hello, ${name}!`;
console.log(greet('Node 6'));
