哪些Gulp包可压缩HTML内容？含内联JSON脚本压缩及转PHP需求

Got it, let's tackle this problem. The core issue here is that gulp-htmlmin (powered by html-minifier under the hood) doesn't minify <script type="application/ld+json"> content by default—it only targets standard JavaScript script types like text/javascript. To handle JSON-LD compression, we'll add two extra tools to your Gulp workflow: gulp-cheerio (for manipulating HTML DOM elements) and jsonminify (for compressing JSON content).

Step 1: Install Required Packages #

First, install the additional dependencies via npm:

npm install gulp-cheerio jsonminify --save-dev

Step 2: Update Your Gulp Task #

Here's the modified Gulp task that handles both HTML/minified JS compression and JSON-LD minification, then renames files to .php:

const gulp = require('gulp');
const htmlmin = require('gulp-htmlmin');
const rename = require('gulp-rename');
const cheerio = require('gulp-cheerio');
const jsonminify = require('jsonminify');

gulp.task('process-html', function() {
  return gulp.src('src/*.html')
    // First: Minify JSON-LD script content
    .pipe(cheerio(function($, file) {
      // Target all application/ld+json script tags
      $('script[type="application/ld+json"]').each(function() {
        const $scriptElement = $(this);
        const rawJson = $scriptElement.html();
        
        try {
          // Compress the JSON (removes whitespace, comments, etc.)
          const minifiedJson = jsonminify(rawJson);
          // Replace the original content with the minified version
          $scriptElement.html(minifiedJson);
        } catch (error) {
          console.error(`Failed to minify JSON-LD in ${file.path}:`, error);
        }
      });
    }, {
      // Keep HTML mode (not XML) to preserve original markup structure
      xmlMode: false
    }))
    // Then: Compress the entire HTML + standard inline JS/CSS
    .pipe(htmlmin({
      collapseWhitespace: true,
      minifyCSS: true,
      minifyJS: true,
      removeComments: true,
      // Add any other htmlmin options you need here
    }))
    // Rename output files to .php
    .pipe(rename({ extname: '.php' }))
    .pipe(gulp.dest('dist'));
});

How This Works #

1. Cheerio Integration: gulp-cheerio parses your HTML into a manipulable DOM structure, letting us target exactly the JSON-LD script tags we need.
2. JSON Compression: jsonminify takes the raw JSON content from each script tag, strips unnecessary whitespace and comments, and outputs a compact valid JSON string.
3. Standard HTML Minification: After fixing the JSON-LD content, we run gulp-htmlmin as usual to compress the rest of the HTML, including standard inline JavaScript and CSS.
4. Rename & Output: Finally, gulp-rename converts the files to .php format before saving to your destination folder.

Why Your Original Setup Didn't Work #

html-minifier (the library behind gulp-htmlmin) only applies JavaScript minification to scripts with types like text/javascript, application/javascript, or no type specified. Since application/ld+json is treated as plain text, it skips compression for those tags—hence the need for the custom DOM manipulation step.
