Question

What is the reason that the npm library is not functioning as expected?

Encountering an issue with the npm library for HTML minify. I have downloaded and declared a library

import htmlmin from 'html-minifier';

However, when attempting to run a gulp task

export const html = () => {
  return gulp.src("source/*.html")
    .pipe(htmlmin({ collapseWhitespace: true }))
    .pipe(gulp.dest("build"));
}

An error is being returned:

TypeError: htmlmin is not a function

Confident that there are no syntax errors, but unsure about the root cause of the problem.

Experimented with different libraries and older versions of node.js, yet the same problem persists.

javascript npm gulp

If you want to learn how to utilize the library, make sure to check out the documentation provided.

A detailed example on how to integrate the library with gulp can be found below:

const { src, dest, series } = require('gulp');
const htmlMinify = require('html-minifier');

const options = {
  includeAutoGeneratedTags: true,
  removeAttributeQuotes: true,
  removeComments: true,
  removeRedundantAttributes: true,
  removeScriptTypeAttributes: true,
  removeStyleLinkTypeAttributes: true,
  sortClassName: true,
  useShortDoctype: true,
  collapseWhitespace: true
};

function html() {
  return src('app/**/*.html')
    .on('data', function(file) {
      const bufferFile = Buffer.from(htmlMinify.minify(file.contents.toString(), options))
      return file.contents = bufferFile
    })
    .pipe(dest('build'))
}

exports.html = series(html)

After installing a specific gulp library called gulp-htmlmin and realizing its potential, I finally got it to work.

const gulp = require('gulp');
const htmlmin = require('gulp-htmlmin');

gulp.task('minify', () => {
  return gulp.src('src/*.html')
    .pipe(htmlmin({ collapseWhitespace: true }))
    .pipe(gulp.dest('dist'));
});
