library0.3.2jsnpmunverified

Grunt plugin for minifying HTML class and id attributes in CSS and HTML files while generating JavaScript map files. Current stable version 0.3.2 (last release unknown). It is a legacy Grunt 0.4.x plugin that renames CSS class names and HTML ids to shorter forms, producing a mapping file for use in development. Key differentiator: targeted at front-end optimization for HTML/CSS with J_ prefix filtering. No longer actively maintained; deprecated in favor of modern webpack or PostCSS-based minification.

grunt-class-id-minifier task
✓ grunt.loadNpmTasks('grunt-class-id-minifier');
✗ const classIdMinifier = require('grunt-class-id-minifier');
Grunt plugin; not a direct import. Use loadNpmTasks in Gruntfile.

Basic Gruntfile configuration that minifies CSS class and HTML id attributes, filtering out names starting with J_.

module.exports = function(grunt) { grunt.initConfig({ 'class-id-minifier': { options: { jsMapFile: 'dist/map.js', jsMapDevFile: 'dist/map.dev.js', minifyFilter: function(name, type) { return !/^J_/.test(name); } }, files: [{ expand: true, cwd: 'src/', src: ['*.html', '*.css'], dest: 'dist/' }] } }); grunt.loadNpmTasks('grunt-class-id-minifier'); grunt.registerTask('default', ['class-id-minifier']); };

fix
Ensure src patterns match *.html and *.css.
