automin

library2.0.3jsnpmunverified

AutoMin is a CLI tool that creates minified mirror copies of your JS, CSS, HTML, and JSON files. Version 2.0.3 is the current stable release. It leverages UglifyJS, clean-css, HTML-minifier, and jsonminify under the hood. Key differentiators include global installation, offline capability, use of uglifyjs nameCache for preserving function names across files, automatic skipping of .git and node_modules, and support for custom minifiers by editing a single file. It requires input and output directories and offers overwrite and merge options.

Code

Verified usage

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

Automin

✓ const automin = require('automin')

✗ import automin from 'automin'

Package does not expose a main module; it is intended as a CLI tool. Use global installation or npx.

CLI usage

✓ automin -i ./src -o ./dist

✗ automin --input ./src --output ./dist --merge --overwrite

The --merge and --overwrite flags cannot be used together. Also, output folder is overwritten by default unless --merge is specified.

Programmatic API

✓ No programmatic API available

✗ const automin = require('automin'); automin.minify(...)

AutoMin is exclusively a CLI tool. There is no exported API for programmatic use.

Installs AutoMin globally and minifies all JS, CSS, HTML, JSON files from ./my-project into ./my-project-min.

npm install -g automin automin -i ./my-project -o ./my-project-min

Debug

Known issues

gotchaOutput folder will be completely overwritten by default, removing any files not in the input. Use --merge to preserve existing files.

fix

Add --merge to your command if you want to keep old files that haven't been processed.

affects: >=1.0.0

breaking--merge and --overwrite cannot be used together. If both provided, the command will fail or behave unexpectedly.

fix

Choose only one of --merge or --overwrite, or omit both.

affects: >=2.0.0

gotchaFiles with .min. before the extension (e.g., .min.js) are skipped by default and will not be minified.

fix

Rename or modify the source to exclude the .min. pattern, or edit the minifier to include them.

affects: >=1.0.0

gotcha.git directories and node_modules are force-skipped. You cannot minify files inside these directories.

fix

Move the files you want to minify outside of .git or node_modules.

affects: >=1.0.0
