Build System Migration

June 20, 2025 · View on GitHub

This project has been migrated from Grunt + Bower to modern npm-based tooling.

What Changed

Before (Grunt + Bower)

  • Grunt: Used for minification and file copying
  • Bower: Used for managing jQuery UI dependencies
  • Gruntfile.js: Complex configuration file
  • bower.json: Separate dependency management

After (npm only)

  • npm scripts: Simple, readable build commands
  • npm dependencies: All dependencies managed in one place
  • uglify-js: Direct minification tool
  • webpack: Optional modern bundler

Available Commands

Basic Build (uglify-js)

npm run build          # Build and copy files
npm run uglify         # Minify only
npm run copy           # Copy unminified to dist
npm run copy-min       # Copy minified to dist
npm run watch          # Watch for changes and rebuild
npm run clean          # Clean generated files

npm run build:webpack      # Production build with webpack
npm run build:webpack:dev  # Development build
npm run watch:webpack      # Watch with webpack

Development

npm run dev               # Start development with uglify-js
npm run dev:webpack       # Start development with webpack

Benefits of Migration

  1. Simplified Setup: No need for Grunt or Bower
  2. Better Performance: Webpack provides better optimization
  3. Modern Tooling: Uses current industry standards
  4. Single Package Manager: Everything managed through npm
  5. Better Source Maps: Improved debugging experience
  6. Tree Shaking: Webpack can eliminate unused code
  7. Hot Reloading: Faster development cycles

Migration Notes

  • jQuery UI: Now managed through npm instead of Bower
  • Dependencies: All moved to package.json
  • Build Process: Simplified and faster
  • Compatibility: Maintains same output format
