html-minifier-loader

library1.4.1jsnpmunverified

Webpack loader that minifies HTML using html-minifier. Current stable version 1.4.1 (last release ~2017). No active maintenance; outdated compared to modern alternatives. Key differentiator: integrates html-minifier as a webpack loader with query params support. Requires peer dependency html-minifier. Note: raw-loader usage example implies raw output; loader is synchronous and not compatible with webpack 4+ loaders API without adaptation.

Code

Verified usage

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

loader

✓ import htmlMinifierLoader from 'html-minifier-loader'

✗ const loader = require('html-minifier-loader')

Used programmatically as a function; typically invoked via webpack config, not direct require.

default

✓ import loader from 'html-minifier-loader'

✗ import { loader } from 'html-minifier-loader'

The package exports a single loader function as default export.

Options

✓ import type { Options } from 'html-minifier'

✗ import { Options } from 'html-minifier-loader'

Type definitions exist only for html-minifier, not this loader.

Example webpack config using html-minifier-loader with raw-loader and custom html-minifier options.

// webpack.config.js const path = require('path'); module.exports = { entry: './src/index.js', output: { path: path.resolve(__dirname, 'dist'), filename: 'bundle.js' }, module: { rules: [ { test: /\.html$/, use: [ 'raw-loader', { loader: 'html-minifier-loader', options: { removeComments: true, collapseWhitespace: true, conservativeCollapse: true } } ] } ] } };

Debug

Known issues

deprecatedPackage is unmaintained since 2017; use html-minimizer-webpack-plugin instead.

fix

Migrate to html-minimizer-webpack-plugin (webpack 5+).

affects: >=1.0.0

breakingWebpack 4+ loader API changes: must use `this.async()` for async loaders; this loader is synchronous.

fix

Consider using html-loader with postprocess or a modern alternative.

affects: >=1.0.0

gotchaOptions must be passed via `options` key in webpack config, not top-level 'html-minifier-loader' property (deprecated config style).

fix

Use `{ loader: 'html-minifier-loader', options: { ... } }` in `use` array.

affects: >=1.0.0

deprecatedRequires raw-loader to output raw string; html-loader v2+ can emit raw strings without raw-loader.

fix

Use html-loader with `esModule: false` and `sources: false` options.

affects: >=1.0.0

gotchaPackage does not support ES module exports; designed for CJS webpack configs.

fix

Use webpack's `resolve.fallback` if using ESM configs.

affects: >=1.0.0

Errors

Common errors & fixes

Module parse failed: Unexpected token (1:0) You may need an appropriate loader to handle this file type.

No loader rule for .html files or incorrect chaining order.

fix

Add raw-loader before html-minifier-loader in use array.

Error: options/query provided without loader (continue line)

Deprecated config syntax in webpack 4+.

fix

Use `{ loader: 'html-minifier-loader', options: { ... } }` inside `rules[].use`.
