library2.32.2jsnpmunverified

A Babel preset for bundling standard (browser-compatible) npm modules in Liferay projects. Current stable version is 2.32.2. It is maintained as part of the Liferay frontend projects monorepo, with releases tied to the liferay-js-toolkit package. The preset includes plugins for normalizing requires, inlining NODE_ENV, dead code elimination, AMD module wrapping, naming, and namespace handling. It differentiates from generic Babel presets by providing Liferay-specific transformations for AMD module support and namespace isolation.

Verified usage

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

default

✓ import babelPresetLiferayStandard from 'babel-preset-liferay-standard'

✗ const babelPresetLiferayStandard = require('babel-preset-liferay-standard')

ESM default import is preferred; CommonJS require works but may not tree-shake.

liferayStandard

✓ import { liferayStandard } from 'babel-preset-liferay-standard'

✗ import { LiferayStandard } from 'babel-preset-liferay-standard'

Named export is lowercase camelCase.

Config

✓ import type { Config } from 'babel-preset-liferay-standard'

✗ import { Config } from 'babel-preset-liferay-standard'

Use type import for TypeScript type definitions.

Demonstrates three ways to configure babel-preset-liferay-standard: .babelrc file, babel.config.js, and package.json babel field.

// Install: npm install --save-dev babel-preset-liferay-standard // .babelrc { "presets": ["liferay-standard"] } // babel.config.js module.exports = { presets: ['babel-preset-liferay-standard'] }; // package.json { "babel": { "presets": ["liferay-standard"] } }

Debug

Known issues

breakingIn version 2.x, the preset requires Babel 7. Using with Babel 6 will throw errors.

fix

Upgrade to Babel 7 or use babel-preset-liferay-standard@1.x.

affects: >=2.0.0

deprecatedbabel-plugin-transform-node-env-inline may be deprecated in future releases; prefer using @babel/plugin-transform-node-env-inline.

fix

Manually replace with the standalone plugin if needed.

affects: >=2.0.0

gotchaThe preset includes dead code elimination; ensure that process.env.NODE_ENV is set correctly to avoid accidental removal of development code.

fix

Set NODE_ENV=production for production builds or use cross-env.

affects: >=2.0.0

gotchaAMD module wrapping can cause conflicts with other module systems (e.g., CommonJS). Ensure your project is AMD-compatible.

fix

Use the preset only in Liferay AMD environments or disable AMD plugins if not needed.

affects: >=2.0.0

Errors

Common errors & fixes

Error: Cannot find module 'babel-preset-liferay-standard'

Package not installed or missing from devDependencies.

fix

Run: npm install --save-dev babel-preset-liferay-standard

ReferenceError: define is not defined

AMD module wrapping expects an AMD loader (e.g., RequireJS) to be present in the browser.

fix

Ensure an AMD loader (like RequireJS) is included or use the preset with a bundler that supports AMD output.

TypeError: Cannot read property 'presets' of undefined

Babel configuration file is malformed or missing module.exports.

fix

Export an object with a presets array: module.exports = { presets: ['liferay-standard'] };

Error: Plugin 2 specified in ".../node_modules/babel-preset-liferay-standard/index.js" returned an object with a "visitor" property, but Babel expects a function.

Incompatible Babel plugin version (e.g., Babel 6 plugin in Babel 7).

fix

Upgrade to Babel 7 or ensure all peer dependencies match.
