Code

Verified usage

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

default

✓ import minifier from 'posthtml-minifier';

✗ const minifier = require('posthtml-minifier').default;

The plugin exports a single function; use default import in ESM, const minifier = require('posthtml-minifier') in CJS works too.

posthtml

✓ import posthtml from 'posthtml';

✗ const posthtml = require('posthtml').posthtml;

PostHTML default export is the main function; not a named export.

minifier

✓ posthtml().use(minifier({ removeComments: true }));

✗ posthtml([minifier({ removeComments: true })]);

Pass the plugin to .use() method, not as an array to posthtml().

Minifies HTML by removing comments and collapsing whitespace using PostHTML pipeline.

const posthtml = require('posthtml'); const minifier = require('posthtml-minifier'); posthtml() .use(minifier({ removeComments: true, collapseWhitespace: true })) .process('<html><head><title>Test</title></head><body><p>Hello</p></body></html>') .then(result => { console.log(result.html); // Output: <html><head><title>Test</title></head><body><p>Hello</p></body></html> });

Debug

Known issues

deprecatedPackage has not been updated since 2016; consider using 'posthtml-minify' or manual html-minifier integration.

fix

Switch to actively maintained alternatives like 'html-minifier-terser' combined with PostHTML manual call.

affects: >=0.1.0

gotchaHTMLMinifier options must be passed as object to the plugin; default options may not minify aggressively.

fix

Explicitly set options like removeComments: true, collapseWhitespace: true, etc.

affects: >=0.1.0

gotchaPlugin does not support async HTMLMinifier versions; error if HTMLMinifier API changes.

fix

Use compatible html-minifier version (<=4.0.0) or lock dependency.

affects: >=0.1.0
