library1.0.2jsnpmunverified

A webpack plugin (v1.0.2) that generates asset files (e.g., JSON) containing the mapping of webpack output assets with their sizes and hash values. It is designed for webpack 4 and helps track compiled assets. The plugin writes an asset.json file to the output directory with details like filename, size, and hash. It is a niche tool compared to plugins like assets-webpack-plugin or webpack-manifest-plugin, which are more feature-rich and actively maintained. Release cadence is low (latest 2018), with no recent updates.

✗ const { AssetFilePlugin } = require('webpack-asset-file-plugin')
Named export does not exist; do not destructure.

Shows how to configure the plugin to output asset.json with compiled file details, excluding source maps.

const AssetFilePlugin = require('webpack-asset-file-plugin'); module.exports = { entry: './src/index.js', output: { path: path.resolve(__dirname, 'dist'), filename: 'bundle.js', }, plugins: [ new AssetFilePlugin({ filename: 'asset.json', excludeAssets: [/.*\.map$/], update: false, path: path.resolve(__dirname, 'dist'), }), ], };

Known issues
breakingPlugin is designed for webpack 4 only; may not work with webpack 5 due to removed hooks.
fix
Use an alternative like webpack-manifest-plugin for webpack 5.

deprecatedThe package has not been updated since 2018; consider it in maintenance mode.
fix
Switch to actively maintained plugins like assets-webpack-plugin or webpack-manifest-plugin.
affects: >=1.0.0
gotchaThe `update` option set to false will overwrite the asset file on each build instead of merging.
fix
Set `update: true` to merge with existing asset file, if that behavior is desired.
affects: >=1.0.0
