gulp-babel-minify

library0.5.2jsnpmunverified

Gulp plugin for babel-minify (formerly Babili), providing a seamless way to minify JavaScript files in a Gulp pipeline. Current stable version is 0.5.2 (2018-09-24), with no updates since then — the project is effectively in maintenance mode. It wraps babel-minify (babel-preset-minify) which uses Babel transforms for dead code elimination, constant folding, mangling, etc. Alternatives like gulp-terser or gulp-uglify are more actively maintained. Requires @babel/core as a peer dependency.

Verified usage

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

gulpBabelMinify (default)

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

✗ import minify from 'gulp-babel-minify';

Package does not ship ESM exports; use CommonJS require(). If using TypeScript, you may need to install @types/gulp-babel-minify (not available) or use a custom declaration.

minify function

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

✗ import { minify } from 'gulp-babel-minify';

No named export exists; the only export is the default function.

custom babel/minify preset

✓ const minify = require('gulp-babel-minify'); minify({ mangle: { keepClassName: true } }, { babel: customBabel, minifyPreset: customPreset });

✗ const minify = require('gulp-babel-minify'); const options = { babel: customBabel };

Custom babel and minifyPreset must be passed as the second argument (overrides object), not inside minifyOptions.

Shows basic Gulp task using gulp-babel-minify with mangle options to minify a JavaScript file.

const gulp = require('gulp'); const minify = require('gulp-babel-minify'); gulp.task('minify', () => gulp.src('./build/app.js') .pipe(minify({ mangle: { keepClassName: true } })) .pipe(gulp.dest('./dist')) );

Debug

Known issues

deprecatedThe babel-minify project is no longer actively maintained. Last release 2018. Consider using gulp-terser or gulp-uglify instead.

fix

Switch to gulp-terser (npm install gulp-terser).

affects: >=0.0.0

breakingIn version 0.3.0, the mangle option 'blacklist' was renamed to 'exclude'. Old code using 'blacklist' will break.

fix

Rename 'blacklist' to 'exclude' in mangle options.

affects: >=0.3.0

breakingIn version 0.4.0, babel-minify switched from Babel 6 to Babel 7. Ensure @babel/core v7+ is installed as peer dependency.

fix

Upgrade @babel/core to v7 and update any Babel config (babelrc, presets) accordingly.

affects: >=0.4.0

gotchaThe 'comments' override option last argument is a Function, RegExp, or Boolean. Using some other type may silently fail.

fix

Ensure the 'comments' value is a Function, RegExp, or Boolean.

affects: >=0.0.0

gotchaWhen using a custom babel or minifyPreset, they must be passed in the second 'overrides' argument, not inside the first options object.

fix

Use: minify({}, { babel: customBabel, minifyPreset: customPreset })

affects: >=0.0.0

Errors

Common errors & fixes

Error: Cannot find module '@babel/core'

@babel/core is a peer dependency not automatically installed.

fix

Run: npm install @babel/core --save-dev

Error: Cannot find module 'babel-preset-minify'

babel-preset-minify is a dependency of gulp-babel-minify but may not be installed if npm peer dependency resolution is strict.

fix

Run: npm install babel-preset-minify --save-dev

TypeError: gulpBabelMinify is not a function

Importing using ESM (import minify from 'gulp-babel-minify') in an environment that expects CJS or missing default export.

fix

Use CommonJS require: const minify = require('gulp-babel-minify');
