WebpackDynamicPublicPathPlugin
✓ const WebpackDynamicPublicPathPlugin = require('webpack-dynamic-public-path');
✗ import WebpackDynamicPublicPathPlugin from 'webpack-dynamic-public-path';
Package does not ship ESM; CommonJS require is required. Using import may cause errors in Node.js.
Shows a minimal webpack 4 config using the plugin to replace the static publicPath placeholder with a window variable.
// webpack.config.js
const path = require('path');
const WebpackDynamicPublicPathPlugin = require('webpack-dynamic-public-path');
module.exports = {
entry: './src/index.js',
output: {
filename: 'bundle.js',
path: path.resolve(__dirname, 'dist'),
publicPath: 'PUBLIC_PATH_PLACEHOLDER',
},
plugins: [
new WebpackDynamicPublicPathPlugin({
externalPublicPath: 'window.myPublicPath',
}),
],
};

Known issues
breakingPlugin only works with webpack 4. Using with webpack 5 will cause undefined behavior or compilation errors.fixUse webpack 5's built-in __webpack_public_path__ or automatic-publicPath guide (https://webpack.js.org/guides/public-path/#automatic-publicpath).
affects: >=5.0.0 of webpack
deprecatedPackage has not been updated since 2019 and is considered deprecated. No support for future webpack versions.fixMigrate to webpack 5+ or consider using runtime publicPath mechanism.
affects: all
gotchaThe externalPublicPath option expects a raw JavaScript expression, not a string literal. For a string constant, wrap in quotes like '"./"' (note single quotes inside double quotes).fixSet externalPublicPath to '"./"' (including single quotes) for a static string, or to a variable reference without quotes.
affects: all
gotchaIf not using chunkNames, publicPath is replaced in ALL chunks. This can break vendor bundles or async chunks if they need a different publicPath.fixAlways specify chunkNames when multiple entries or code splitting is used to avoid unintended replacements.

Errors

TypeError: Cannot read property 'tapAsync' of undefined
Using the plugin with webpack 5 (or incompatible version) where the hooks API changed.
fixDowngrade to webpack 4 or switch to webpack 5 native publicPath handling.
Module not found: Error: Can't resolve 'webpack-dynamic-public-path'
Package not installed or import path incorrect (e.g., using ESM import).
fixInstall with 'npm install webpack-dynamic-public-path' and use require('webpack-dynamic-public-path'). Audit
