rollup-plugin-swc-minify

1.3.0 verified Mon Apr 27 auth: no javascript

Rollup plugin to minify generated bundles using swc. Version 1.3.0 supports Rollup ^2, ^3, or ^4 and requires Node.js >= 14.18. It focuses solely on minification, making it simpler than rollup-plugin-swc which does transpilation. It is benchmarked to be faster than @rollup/plugin-terser. Provides options for format, sourcemap, and sourcemapExcludeSources. Licensed under MIT.

Common errors

error Error [ERR_MODULE_NOT_FOUND]: Cannot find package 'rollup-plugin-swc-minify' ↓

cause Package not installed or mismatched rollup peer dependency version.

fix

Run npm install -D rollup-plugin-swc-minify and ensure rollup version is ^2 || ^3 || ^4.

error Error: 'minify' is not exported from 'rollup-plugin-swc-minify' ↓

cause Using default import or wrong import syntax.

fix

Use the named import: import { minify } from 'rollup-plugin-swc-minify'.

error Error: The specified module could not be found. (ERR_REQUIRE_ESM) ↓

cause Attempting to require() the ESM-only package.

fix

Use import instead of require(), or set type: 'module' in package.json.

error Error: Rollup plugin 'minify' is not a function ↓

cause Using the plugin as a class/constructor instead of calling the function.

fix

Use minify() (call the function) instead of new minify() or just minify.

Warnings

breaking Package is ESM-only; require() will throw ERR_REQUIRE_ESM. ↓

fix Use import statements or dynamic import() instead of require().

gotcha The plugin does not transpile code; it only minifies. If you need JSX/TypeScript support, use rollup-plugin-swc or another transpiler first. ↓

fix Use rollup-plugin-swc for transpilation before minification.

gotcha The 'format' option only affects minification output, not Rollup's output format. Ensure Rollup output format matches. ↓

fix Set rollup output.format appropriately (e.g., 'es') and optionally pass format to minify() for accurate minification.

deprecated The 'sourcemapExcludeSources' option may be removed in future versions; use source maps carefully. ↓

fix Set sourcemap: true and control source map content via Rollup options if possible.

export default {
  input: 'src/index.js',
