mu-babel

library0.0.2jsnpmunverified

An unofficial fork/package of Babel (formerly 6to5) that transpiles ES6/ES2015 to readable ES5 with source maps. Version 0.0.2 is an early snapshot from the Babel v5 era (circa 2015), long superseded by modern Babel versions. This package is not maintained and should not be used in new projects. Key differentiator: claims readable output, but functionally identical to early Babel releases. Users should prefer the official babel package at v7+.

Code

Verified usage

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

mu-babel

✓ import babel from 'mu-babel'

✗ const babel = require('mu-babel')

Package exposes a default export similar to Babel v5. Usage from mu-babel is identical to early babel packages.

babel.transform

✓ import babel from 'mu-babel'; babel.transform(code, options)

✗ import { transform } from 'mu-babel'

The package does not export transform as a named export; it is a method on the default export.

babel.version

✓ import babel from 'mu-babel'; console.log(babel.version)

✗ import { version } from 'mu-babel'

Version property on the default export.

Shows how to transpile a simple const declaration using mu-babel with source maps.

const babel = require('mu-babel'); const result = babel.transform('const x = 1;', { sourceMaps: true }); console.log(result.code); // 'use strict'; // var x = 1;

babel --version

Debug

Known issues

breakingPackage mu-babel is an unmaintained fork of Babel v5.x. It lacks support for modern JavaScript (ES2016+), plug-in system, and bug fixes.

fix

Migrate to the official babel package: npm uninstall mu-babel && npm install --save-dev @babel/core @babel/cli @babel/preset-env

affects: >=0.0.1

deprecatedThe API mirror is Babel v5, which is obsolete. Methods like babel.transform() differ from @babel/core.

fix

Use @babel/core and consult its documentation for API changes.

affects: >=0.0.1

gotchaThe package name mu-babel is easily confused with the official babel packages. Installing it may lead to missing security patches and incompatibilities.

fix

Always install @babel/core (or babel-cli) from the official scoped package.

affects: >=0.0.1
