css-simple-minifier

library2.0.1jsnpmunverified

A CSS minifier that is tiny and very fast, removing most unnecessary whitespace to achieve ~95% of the compression of full-blown minifiers in ~5% of the time. Current stable version is 2.0.1. It ships TypeScript type definitions. Compared to alternatives like csso or clean-css, this package prioritizes simplicity and speed over maximum compression, making it ideal for development workflows or where quick minification is needed. It is actively maintained with a focused feature set.

Code

Verified usage

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

minify

✓ import minify from 'css-simple-minifier'

✗ import { minify } from 'css-simple-minifier'

The package has a default export. Using named import will not work. Since v2, the package is ESM-only, so require() is not supported in Node.

minify

✓ const minify = require('css-simple-minifier').default

✗ const minify = require('css-simple-minifier')

If using CommonJS with older Node versions, you must access .default. However, v2.0.1 is ESM-only, so require() will throw. Use dynamic import() instead.

minify

✓ const minify = (await import('css-simple-minifier')).default

✗ const { minify } = await import('css-simple-minifier')

When using dynamic import() in CommonJS, you still need .default because the package exports a default export.

Demonstrates importing and using the default export to minify a CSS string, preserving property values but removing unnecessary whitespace.

import minify from 'css-simple-minifier'; const css = ` .foo, .bar { color: red; } .baz { color: blue; } `; const minified = minify(css); console.log(minified); // => '.foo,.bar{color: red;}.baz{color: blue;}'

Debug

Known issues

breakingv2 dropped CommonJS support; package is ESM-only. Using require() will throw ERR_REQUIRE_ESM.

fix

Use import or dynamic import() instead of require(). If you must use CommonJS, stay on v1.x.

affects: >=2.0.0

gotchaThe package only removes whitespace where safe, leaving property values intact. It will not remove comments, collapse hex codes, or apply advanced optimizations.

fix

If you need full CSS minification, consider using csso or clean-css instead.

affects: *

gotchaDefault export only. Attempting named import like { minify } will result in undefined.

fix

Use default import: import minify from 'css-simple-minifier'.

affects: *

Errors

Common errors & fixes

ERR_REQUIRE_ESM

Using require() to import an ESM-only package in Node.js.

fix

Replace const minify = require('css-simple-minifier') with import minify from 'css-simple-minifier' or const minify = (await import('css-simple-minifier')).default.

TypeError: minify is not a function

Using named import { minify } which does not exist.

fix

Change to import minify from 'css-simple-minifier' (default import).

undefined is not a function (evaluating 'minify(css)')

Attempting to call the result of a named import which is undefined.

fix

Use default import instead of named import.
