Why use this package?

Using CDN packages directly has many advantages:

  • No need to download and host files
  • No extra build steps (no need to compile SCSS, minify JS, etc.)
  • Automatic updates
  • Faster delivery
  • Reduced server load

        Child(hb.Script().Src(cdn.BootstrapJs_5_3_3()))
