webpack-manifest-plugin

library6.0.1jsnpmunverified

A Webpack plugin that generates a JSON manifest file mapping source filenames to their corresponding built output filenames, useful for server-side rendering or cache busting. Current stable version is 6.0.1, which is ESM-only and requires Node.js 20.19.0+ and Webpack 5.75.0+. Maintained by shellscape. Releases follow semantic versioning with major breaking changes in v6 (ESM switch, Node 20+), v5 (drop webpack v4), v4 (TypeScript types added). Primarily differentiates from similar plugins by its simplicity and configurability (filter, map, generate options). Peer dependency on webpack ^5.75.0.

Verified usage

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

WebpackManifestPlugin

✓ import { WebpackManifestPlugin } from 'webpack-manifest-plugin'

✗ const WebpackManifestPlugin = require('webpack-manifest-plugin')

ESM-only since v6.0.0; require() will throw ERR_REQUIRE_ESM.

type FileDescriptor

✓ import type { FileDescriptor } from 'webpack-manifest-plugin'

✗ import { FileDescriptor } from 'webpack-manifest-plugin'

FileDescriptor is a TypeScript type (exported as type), not a runtime value.

default import

✓ import { WebpackManifestPlugin } from 'webpack-manifest-plugin'

✗ import WebpackManifestPlugin from 'webpack-manifest-plugin'

This package exports only a named member, not a default export.

Minimal webpack config ESM showing plugin setup with common options: fileName, basePath, publicPath, filter, and map.

// webpack.config.mjs import { WebpackManifestPlugin } from 'webpack-manifest-plugin'; export default { entry: './src/index.js', output: { filename: '[name].[contenthash:8].js', path: new URL('./dist', import.meta.url).pathname, }, plugins: [ new WebpackManifestPlugin({ fileName: 'asset-manifest.json', basePath: '/app/', publicPath: '/app/', filter: (file) => file.isInitial, map: (file) => ({ ...file, path: file.path.replace(/^\.\//, '') }), }), ], mode: 'production', };

Known issues

breakingv6.0.0 dropped CommonJS support; only ESM is supported.

fix

Convert project to ESM or continue using v5.x if CJS is required.

affects: >=6.0.0

breakingv6.0.0 requires Node.js >=20.19.0.

fix

Upgrade Node.js to 20.19.0 or later, or pin to v5.x.

affects: >=6.0.0

breakingv5.0.0 dropped support for webpack v4.

fix

Upgrade to webpack v5 or use v4.x of this plugin.

affects: >=5.0.0 <6.0.0

deprecatedOption 'useLegacyEmit' was removed in v5 without replacement.

fix

Remove 'useLegacyEmit' from options; use 'assetHookStage' instead.

affects: >=5.0.0

gotchaIf using the 'filter' option, ensure it returns Boolean. Incorrect return values (e.g. undefined) cause unexpected behavior.

fix

Always explicitly return true/false from the filter function.

affects: >=3.0.0

gotchaThe 'generate' option replaces the entire manifest object. If 'generate' is provided, 'filter', 'map', and other options are ignored for that function's logic.

fix

Use 'generate' only when you need full control; otherwise use 'filter'/'map'.

affects: >=3.0.0

Errors

Common errors & fixes

Error [ERR_REQUIRE_ESM]: require() of ES Module /path/to/webpack-manifest-plugin/dist/index.js from /path/to/project/webpack.config.js not supported.

Using require() with an ESM-only package (v6+).

fix

Change config to ESM: rename file to .mjs and use import, or use dynamic import().

TypeError: file.isInitial is not a function

Using the 'filter' option and referencing 'isInitial' incorrectly (it's a boolean property, not a method).

fix

Use file.isInitial directly: filter: (file) => file.isInitial

Module parse failed: Unexpected token with webpack 4

Using webpack-manifest-plugin v5+ with webpack v4.

fix

Upgrade to webpack v5 or use webpack-manifest-plugin v4.x.
