unused-files-webpack-plugin

library3.4.0jsnpmunverified

A Webpack plugin that globs all files under the webpack context and reports which files are not required by the bundle. Version 3.4.0 is the latest stable release, with an unclear release cadence (last release appears to be in 2018). It differs from alternatives like `unused-webpack-plugin` by using `glob-all` for pattern matching and supporting `failOnUnused` to emit errors. The plugin helps identify dead code and redundant files in webpack projects. Note: The plugin is no longer actively maintained; users should consider alternatives or verify compatibility with modern webpack versions.

Code

Verified usage

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

default

✓ import UnusedFilesWebpackPlugin from 'unused-files-webpack-plugin'

✗ const UnusedFilesWebpackPlugin = require('unused-files-webpack-plugin')

Package exports default as both ES module and CommonJS; require() returns default, not named.

UnusedFilesWebpackPlugin

✓ import { UnusedFilesWebpackPlugin } from 'unused-files-webpack-plugin'

✗ const { UnusedFilesWebpackPlugin } = require('unused-files-webpack-plugin').default

Named export is also available in ES module; in CJS, it's { UnusedFilesWebpackPlugin } directly from require().

PluginOptions

✓ import type { PluginOptions } from 'unused-files-webpack-plugin'

TypeScript types are included; use type import for options interface.

Shows how to add the plugin to webpack config with default options, identifying all files not compiled.

// webpack.config.js const UnusedFilesWebpackPlugin = require('unused-files-webpack-plugin'); module.exports = { // ... other webpack config plugins: [ new UnusedFilesWebpackPlugin({ patterns: ['**/*.*'], failOnUnused: false, globOptions: { ignore: 'node_modules/**/*' } }) ] };
