module-minifier

library1.0.5jsnpmunverified

A Node.js module minifier that leverages Webpack and Terser to optimize JavaScript packages. Version 1.0.5 is the current stable release, with no recent updates or clear release cadence. It ships TypeScript declarations, making it suitable for both JavaScript and TypeScript projects. Differentiators include a simple API that integrates Webpack and Terser without requiring complex configuration, though it may lack the granularity of using those tools directly.

Code

Verified usage

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

minifier

✓ const minifier = require('module-minifier')

✗ import minifier from 'module-minifier'

Current version uses CommonJS; no default ESM export. Verify if ESM support is added in future versions.

minifier

✓ import * as minifier from 'module-minifier'

✗ import minifier from 'module-minifier'

ESM namespace import works if the package is used with a bundler that supports it, but default import is not available.

minifier

✓ const { minify } = require('module-minifier')

✗ const minify = require('module-minifier').minify

Destructuring is the preferred CJS pattern; dot-notation property access also works but less idiomatic.

Demonstrates basic usage: reading a file, minifying with the default options, and writing the result. The package exports a `minify` function that returns a promise.

const minifier = require('module-minifier'); const fs = require('fs'); const code = fs.readFileSync('input.js', 'utf8'); minifier.minify(code, { sourceMap: false }).then(result => { fs.writeFileSync('output.js', result.code); }).catch(err => console.error(err));

Debug

Known issues

gotchaThe package uses CommonJS require; importing as default with ES modules fails.

fix

Use namespace import (`import * as minifier`) or use require().

affects: >=1.0.0

deprecatedThe API may change with future major versions; not yet stable.

fix

Pin version to 1.0.x and monitor changelog.

affects: <=1.0.5

gotchaTerser options are passed directly; note that Terser's `mangle` options may not be fully validated.

fix

Refer to Terser documentation for valid options.

affects: >=1.0.0

Errors

Common errors & fixes

TypeError: minifier.minify is not a function

Default import in ESM does not resolve to the exported object.

fix

Use `import * as minifier` or `const { minify } = require('module-minifier')`.

Error: Cannot find module 'webpack'

Webpack is a peer dependency and must be installed separately.

fix

Run `npm install webpack` in your project.

SyntaxError: Unexpected token (at line X)

Input code may contain modern syntax not supported by the default Terser config.

fix

Provide a Terser options object with appropriate `ecma` version or use a different parser.
