swc-minify-webpack-plugin

library2.1.3jsnpmunverified

A webpack plugin that uses swc.minify() to minify JavaScript bundles, offering faster performance than terser-webpack-plugin's swc mode. Current stable version is 2.1.3, released under Apache 2.0 license. It provides simpler options, enables mangle by default for better compression, and is a fork of swc-webpack-plugin with improved performance by using swc.minify() instead of swc.transform(). Requires webpack 5+ and @swc/core 1+ as peer dependencies. Ships TypeScript type definitions.

Verified usage

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

SwcMinifyWebpackPlugin

✓ import { SwcMinifyWebpackPlugin } from 'swc-minify-webpack-plugin'

✗ import SwcMinifyWebpackPlugin from 'swc-minify-webpack-plugin'

v2.0.0 changed default export to named export. ESM and CJS both use named export.

SwcMinifyWebpackPlugin

✓ const { SwcMinifyWebpackPlugin } = require('swc-minify-webpack-plugin')

✗ const SwcMinifyWebpackPlugin = require('swc-minify-webpack-plugin')

CJS require must destructure the named export. In v1, default export was used.

Basic usage of swc-minify-webpack-plugin as the sole minimizer in webpack's optimization configuration.

// webpack.config.js const { SwcMinifyWebpackPlugin } = require('swc-minify-webpack-plugin'); module.exports = { optimization: { minimize: true, minimizer: [new SwcMinifyWebpackPlugin()], }, };

Debug

Known issues

breakingv2.0.0: Changed default export to named export. Import must use destructuring.

fix

Change `import SwcMinifyWebpackPlugin from 'swc-minify-webpack-plugin'` to `import { SwcMinifyWebpackPlugin } from 'swc-minify-webpack-plugin'`

affects: >=2.0.0

deprecatedv1.x: The default export pattern is deprecated and will not work with v2.

fix

Upgrade to v2 and use named export.

affects: 1.x

gotchaConfiguration options `compress`, `mangle`, and `format` are passed directly to swc.minify(). Incorrect options may silently fail or produce unexpected output.

fix

Refer to swc documentation for valid options: https://swc.rs/docs/configuration/minification

affects: >=1.0.0

Errors

Common errors & fixes

Error: Cannot find module 'swc-minify-webpack-plugin'

Package not installed or incorrect import path.

fix

Run `npm install -D swc-minify-webpack-plugin` and ensure import uses require or import correctly.

TypeError: SwcMinifyWebpackPlugin is not a constructor

Using default import instead of named import in v2.

fix

Use named import: `import { SwcMinifyWebpackPlugin } from 'swc-minify-webpack-plugin'`

ValidationError: Invalid options object. Minimizer Plugin has been initialized using an options object that does not match the API schema.

Incorrect options passed to SwcMinifyWebpackPlugin constructor.

fix

Check options: only `compress`, `mangle`, and `format` are supported. Pass them as an object: `new SwcMinifyWebpackPlugin({ compress: false })`
