library1.0.17jsnpmunverified

A webpack plugin that replaces references to static files (CSS, JS, images, SVG sprites) in HTML templates and source files with their contenthash-based filenames. Current stable version is 1.0.17 (last updated August 2017). It requires the loader-utils package and works with webpack 3.x and older. Unlike webpack's built-in [contenthash] support, this plugin directly modifies text files (not just output filenames) and is useful for projects that need to update hardcoded paths in templates or source code. It is considered legacy; modern webpack versions (4+) have native similar functionality.

default
✓ const ReplacerContenthashWebpackPlugin = require('replacer-contenthash-webpack-plugin');
✗ import ReplacerContenthashWebpackPlugin from 'replacer-contenthash-webpack-plugin';
Package is CommonJS-only; ESM import will fail.
ReplacerContenthashWebpackPlugin
✓ const ReplacerContenthashWebpackPlugin = require('replacer-contenthash-webpack-plugin');
✗ const { ReplacerContenthashWebpackPlugin } = require('replacer-contenthash-webpack-plugin');
It is a default export, not a named export.
WebpackPluginInstance
✓ new ReplacerContenthashWebpackPlugin({ filesDir: ['src'] })
✗ ReplacerContenthashWebpackPlugin({ filesDir: ['src'] })
Must be instantiated with new keyword.

Basic webpack config showing plugin instantiation with filesDir and templatesFolder options.

const path = require('path'); const ReplacerContenthashWebpackPlugin = require('replacer-contenthash-webpack-plugin'); module.exports = { entry: './src/index.js', output: { path: path.resolve(__dirname, 'dist'), filename: '[name].js', publicPath: '/static/' }, plugins: [ new ReplacerContenthashWebpackPlugin({ filesDir: ['src'], templatesFolder: ['templates'] }) ] };
Debug
Known issues
deprecatedPackage is unmaintained since 2017; not compatible with webpack 4+ or webpack 5.
fix
Use webpack's built-in [contenthash] or a maintained alternative like gulp-rev.
affects: >=1.0.0
breakingPlugin requires the 'loader-utils' package as a peer dependency. Missing it will cause runtime errors.
fix
Run: npm install loader-utils --save-dev
affects: >=1.0.0
gotchaThe plugin modifies files in-place; ensure you have backups or version control.
fix
Only run plugin on copies of files or ensure you can revert changes.
affects: >=1.0.0
gotchafiles and templates options expect comma-separated strings for multiple files, not arrays. Example: 'file1.js, file2.js'
fix
Pass a single string with comma-separated paths for each property.
affects: >=1.0.0
deprecatedNo security updates; potential vulnerabilities in dependencies (loader-utils, webpack 3).
fix
Migrate to a modern alternative like webpack-subresource-integrity or html-webpack-plugin with hash.
affects: >=1.0.0
