babel-minify

library0.5.2jsnpmunverified

An ES6+ aware JavaScript minifier based on the Babel toolchain. Current stable version is 0.5.2, released in 2018. Development has been stalled since then; it is effectively in maintenance mode. Unlike traditional minifiers (UglifyJS, Terser), babel-minify operates on an AST that can understand modern ES6+ syntax, allowing it to minify code without needing to down-compile first. It works as a standalone CLI tool or as a Babel preset. Note: it is deprecated in favor of Terser for most use cases because Babel itself stopped maintaining it.

Install & Compatibility

Where this runs

No compatibility data collected yet for this library.

Code

Verified usage

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

minify

✓ const minify = require('babel-minify');

✗ import minify from 'babel-minify';

babel-minify does not ship ES module exports; use CommonJS require. The default export is a function.

minify

✓ const minify = require('babel-minify').default || require('babel-minify');

✗ const minify = require('babel-minify').minify;

There is no named export 'minify'; the default export is the function. In some bundlers, .default may be needed.

transform

✓ const { transform } = require('@babel/core');

✗ const { transform } = require('babel-minify');

babel-minify does not expose a transform function; use @babel/core for full Babel transformations.

Demonstrates basic usage of babel-minify Node API with mangling and dead code elimination options.

Debug

Known issues

deprecatedbabel-minify is no longer actively maintained; Babel recommends using Terser for minification.

fix

Switch to terser for active development and bug fixes.

affects: >=0.5.0

breakingBreaking change in 0.4.0: significant API overhaul; compatibility with older babel versions dropped.

fix

Update code to use new API; refer to changelog.

affects: >=0.4.0 <0.5.0

breakingRenamed from Babili to babel-minify in 0.2.0; package name changed.

fix

Replace 'babili' requires with 'babel-minify'.

affects: >=0.2.0

gotchaDoes not support ES module imports; must use require() or configure bundler accordingly.

fix

Use CommonJS require; if using ESM, consider dynamic import or use Terser.

affects: *

gotchaMissing dependencies in versions 0.5.0 and 0.5.1 causing installation failures.

fix

Upgrade to 0.5.2 or manually install missing peer dependencies like @babel/core.

affects: >=0.5.0 <=0.5.1

Errors

Common errors & fixes

Error: Cannot find module 'babel-plugin-minify-dead-code-elimination'

Missing dependency in babel-minify 0.5.0/0.5.1; the package didn't declare all dependencies.

fix

Upgrade to babel-minify@0.5.2 or install missing plugins manually.

TypeError: minify is not a function

Using ES module import (import minify from 'babel-minify') which returns an object with default property, not the function directly.

fix

Use `const minify = require('babel-minify');` or in ESM: `import minify from 'babel-minify';` with proper bundler handling.

Error: Preset babel-preset-minify not found.

babel-preset-minify is a peer dependency not automatically installed; missing or wrong version.

fix

Install babel-preset-minify explicitly: npm install babel-preset-minify --save-dev

ENOENT: no such file or directory, open 'input.js'

CLI command invoked without specifying input file correctly or file does not exist.

fix

Ensure input file path is correct and use --out-file for output.
