babel-preset-es2017-node7

library0.5.2jsnpmunverified

Babel preset that adds missing ES2017 features for Node.js 7 (v7.0.0–7.6.0+). Current stable version: 0.5.2. This package is a legacy Babel 6 preset designed specifically for Node 7's native ES2017 support. It transforms modules (CommonJS), export extensions, class properties, object rest spread, and trailing function commas. No active development; the Babel ecosystem has moved to Babel 7+ and `@babel/preset-env`. Differentiator: minimal additions for Node 7 harmony mode, including a webpack2 variant. Release cadence: last published in 2017.

Configure Babel 6 with es2017-node7 preset for Node 7 harmony mode.

// .babelrc { "presets": ["es2017-node7"] } // Or via CLI: // babel script.js --presets es2017-node7 // Or via Node API: const babel = require('babel-core'); const code = 'const obj = {a: 1, ...rest};'; const result = babel.transform(code, { presets: ['es2017-node7'] }); console.log(result.code);
