webpack-plugin-hash-output

A Webpack plugin that replaces chunkhash placeholders with an MD5 hash of the final file content, computed after all other plugins (like UglifyJsPlugin) have run. v3.2.1 requires Webpack >=4. Unlike other hash plugins that compute hashes earlier, this plugin ensures that any change in the build pipeline—including minification configuration—is reflected in the output hash, preventing cache conflicts. It supports sourcemaps partially and has known ordering requirements with plugins like HtmlWebpackPlugin. Maintained on GitHub, low release cadence (last release 2020).
