babel-preset-lux

2.0.2 verified Sat Apr 25 auth: no javascript maintenance

A Babel preset that bundles all plugins required by Lux, a React-like framework by Postlight. Version 2.0.2 is the latest stable release, last updated in 2018. It targets Node >= 6.0 and includes preconfigured transforms for JSX, class properties, and other modern JavaScript features used by Lux. Compared to general-purpose presets like babel-preset-env, this preset is tightly coupled to Lux's specific plugin set and is not intended for standalone use. Maintenance is minimal as the Lux project itself appears inactive.

Common errors

error Error: Cannot find module 'babel-preset-lux' ↓

cause Package not installed or not saved to devDependencies.

fix

npm install --save-dev babel-preset-lux

error Plugin/Preset files are not allowed to export objects, only functions. ↓

cause Using incompatible Babel version (likely >=7) with this preset.

fix

Use babel-core v6 or find a Babel 7 compatible preset.

Warnings

deprecated babel-preset-lux is effectively unmaintained; use with modern Babel 7+ may break. ↓

fix If using Babel 7, switch to @babel/preset-env and include Lux-specific plugins manually.

breaking Version 2.0.0 changed plugin set; update may break code relying on old transforms. ↓

fix Review release notes for removed plugins.

gotcha Requires babel-core v6; incompatible with @babel/core. ↓

fix Install babel-core v6 alongside, not @babel/core.

deprecated Node 6.0+ requirement; older Node versions not supported. ↓

fix Upgrade Node to >= 6.0 or use a different preset.

Install

npm install babel-preset-lux

yarn add babel-preset-lux

pnpm add babel-preset-lux

Imports

default preset
wrong
```
{
  "presets": ["babel-preset-lux"]
}
```
correct
```
{
  "presets": ["lux"]
}
```
Babel resolves presets with 'babel-preset-' prefix automatically, so just 'lux' works.

require in Node API

wrong

const babel = require('@babel/core'); babel.transform('code', { presets: ['lux'] })

correct

require('babel-core').transform('code', { presets: ['lux'] })

This preset predates @babel/core; use babel-core, not @babel/core for v2.

npx babel

wrong

npx babel script.js --presets babel-preset-lux

correct

npx babel script.js --presets lux

CLI also auto-resolves the preset name.
