babel-preset-node6

11.0.0 verified Sat Apr 25 auth: no javascript deprecated

v11.0.0 — Babel preset that transpiles only the ES2015 features missing in Node 6.x (V8 v5.x, ~93% coverage). Unlike the full ES2015 preset, this complements native V8 support, resulting in faster builds and execution. The preset includes only two plugins: trailing function commas and CommonJS modules. Last updated in 2017; no newer releases for current Node versions.

Common errors

error Error: Couldn't find preset "babel-preset-node6" relative to directory ↓

cause Preset not installed or incorrect name used in configuration.

fix

Run npm install babel-preset-node6 and use short name "node6" in presets array.

error SyntaxError: Unexpected token import ↓

cause Babel not configured to transpile ES modules.

fix

Ensure .babelrc includes "presets": ["node6"] and that babel-register or babel-cli is used.

Warnings

deprecated Node 6.x reached End of Life in April 2019. This preset is not maintained and should not be used for new projects. ↓

fix Use a modern Babel preset like @babel/preset-env with target 'node 10' or higher.

gotcha Does not include full ES2015 coverage; only trailing commas and CommonJS modules are transpiled. Other missing features (e.g., Symbol, Proxy) are not polyfilled. ↓

fix Add babel-polyfill or @babel/polyfill for complete ES2015 support.

breaking Requires Babel 6.x. Incompatible with Babel 7.x (now @babel/... packages). ↓

fix Use @babel/preset-env with Babel 7 instead.
