Barba JS integrates the Barba.js library with Drupal to deliver smooth,
SPA‑like page transitions with minimal setup. It auto‑loads a local build when
present, or falls back to the official CDN. The optional UI submodule lets you
control where and how the library is attached.

Features

• Smooth, SPA‑like page transitions using Barba.js.
• No jQuery dependency; lightweight UMD builds.
• Automatic local vs. CDN loading with safe fallback.
• Optional plugins: CSS, Prefetch, Router.
• Granular control via “Barba JS UI” (themes, paths, plugins, variant).

Use this module when you want faster, more fluid navigation without adopting a
full SPA framework. Typical use cases include content sites, portfolios, blogs,
and marketing pages where page transitions improve perceived performance and UX.

Post-Installation

1. Enable Barba JS (auto‑attaches Barba to frontend pages).
2. (Optional) Enable Barba JS UI for configuration at
   Configuration → User interface → Barba
   (/admin/config/user-interface/barba/settings).
3. Choose attach method: Local (if UMD files exist) or CDN.
4. Select plugins (CSS / Prefetch / Router) and build variant (min/non‑min).
5. Limit loading by theme or by path patterns as needed.
6. Add your transition code in your theme or a custom module:
   

   barba.init({
     transitions: [{
       name: 'fade',
       async leave({ current }) {
         await gsap.to(current.container, { opacity: 0 });
       },
       enter({ next }) {
         return gsap.from(next.container, { opacity: 0 });
       }
     }]
   });

Additional Requirements

• None. Barba.js can load from the bundled dist/ or jsDelivr CDN.
• (Optional) Local install: place UMD builds under
  libraries/barba/dist/ (or multisite equivalent).

Recommended modules/libraries

• Barba JS UI (submodule): adds a configuration UI.
• GSAP (optional): for richer animation timelines.

Similar projects

Modules that provide PJAX/AJAX navigation may offer partial page swaps, but
Barba JS focuses on transition orchestration, view lifecycle hooks, and plugin
ecosystem (CSS/Prefetch/Router) while staying library‑agnostic and lightweight.
