library1.2.0jsnpmunverified

Babel 6 preset for Node.js 7.10–8.x. This preset enables ES2015+ features that are not natively supported in Node 7.10+, including class properties, object rest/spread, export extensions, async generators, and trailing function commas. It also includes production-specific minification and dead code elimination plugins. Version 1.2.0 is the latest stable release. This package is specifically tailored for Node 7.10 to 8.x and is not intended for use with other Node versions or Babel 7.

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default (preset)

✓ import babelPresetNode8 from 'babel-preset-node8'

✗ const babelPresetNode8 = require('babel-preset-node8')

The preset is typically used via .babelrc as a string 'node8', not directly imported in code. However, if importing via Node API, use default import.

createPreset

✓ import createPreset from 'babel-preset-node8/lib/create-preset'

✗ import { createPreset } from 'babel-preset-node8'

The createPreset helper is a separate internal module; not exported from the main package.

env

✓ import envPreset from 'babel-preset-node8/lib/env'

✗ import { env } from 'babel-preset-node8'

The 'env' preset variant is an internal module; do not import it directly.

Show how to install and configure the babel-preset-node8 preset for Babel 6.

npm install --save-dev babel-preset-node8 # .babelrc { "presets": ["node8"] } # Use with babel-cli # babel src --out-dir dist --presets node8

Debug

Known issues

deprecatedBabel 6 is deprecated; Babel 7 is now standard. This preset does not support Babel 7.

fix

Use @babel/preset-env with targets for Node 8 instead.

affects: >=1.0.0

breakingThis preset is specifically for Node 7.10–8.x. Using it with Node 6 or Node 9+ may cause compatibility issues.

fix

Use babel-preset-node6 for Node 6, or babel-preset-env for broader Node support.

affects: >=1.0.0

gotchaThe production plugins (block-scoping, for-of, minify) are automatically applied based on NODE_ENV. If NODE_ENV is not set, production plugins are not used.

fix

Set NODE_ENV=production explicitly to enable production optimizations.

affects: >=1.0.0

gotchasyntax-trailing-function-commas is a syntax plugin only; it does not transform code. Ensure that your target Node version supports trailing commas in function calls (Node 8).

fix

If targeting Node <8, do not rely on this plugin for runtime support.

affects: >=1.0.0

Errors

Common errors & fixes

Error: Plugin/Preset files are not allowed to export objects, only functions. In /path/to/node_modules/babel-preset-node8/index.js

Using this preset with Babel 7 or newer, which expects presets to export functions instead of objects.

fix

Migrate to Babel 7 and use @babel/preset-env instead.

ReferenceError: regeneratorRuntime is not defined

The preset does not include async-to-generator or regenerator runtime; async/await must be natively supported by Node 7.10+.

fix

Ensure Node version is >=7.10, or add @babel/plugin-transform-runtime and @babel/runtime.

Module not found: Can't resolve 'babel-preset-node8' in /path/to/project

The preset is not installed or the package name is misspelled.

fix

Run 'npm install --save-dev babel-preset-node8' and ensure package.json includes it.
