Whakerexa — A minimalist and lightweight web kit for accessible contents

Overview

Whakerexa is a lightweight front-end toolkit that blends clarity, accessibility, and flexibility, and long-term maintainability.
It provides a modern CSS foundation and a fully modular ES6 JavaScript components to build interfaces that are both elegant and inclusive — with minimal code and maximum readability, without dependencies.

Designed around accessibility from the start, Whakerexa makes it easy to craft clean, human-friendly HTML that just works — without drowning your pages in class names or dependencies.
Every visual aspect — colors, typography, spacing, animations — is defined through CSS variables, giving you full creative control with a few redefinitions.

Version 2.0 introduces a unified public API through wexa.js and a stable global namespace through wexa.bundle.js, ensuring support for both modern ES6 module-based applications and offline/static environments.

It pairs naturally with WhakerPy, the lightweight Python library for generating dynamic HTML, offering a seamless workflow from code to design.

Version 1.0

Version 1.0 establishes Whakerexa as a modular, object-oriented web kit centered on a unified entry point.

• Core entry point: wexa.js, which instantiates:

  1. OnLoadManager — Delayed, ordered component initialization.
  2. WexaLogger — Unified logging.
  3. AccessibilityManager — Themes and contrast.
  4. MenuManager — Navigation menus and submenus.
  5. DialogManager — Opening/closing dialogs and popup videos.

• Menus are fully re-implemented (CSS + JS). See docs/menu.html.

• Dialogs are managed by DialogManager (legacy functions replaced).
• Backward compatibility with pre-1.0 procedural APIs is limited and not fully ensured.
• Not all minor/specialized classes have been ported (e.g., Book, ToggleSelector, SortaTable).

This version also includes a set of monochrome SVG icons.

Version 2.0

Version 2.0 is a complete modernization.
Previous procedural APIs are not preserved.

• Unified ES6 entry point (wexa.js) exporting all components.
• wexa.bundle.js exposes the global namespace window.Wexa for file:// usage.
• The progress() function is removed. Use the ProgressBar class instead (see docs/progressbar.html).
• Use Wexa.onload instead of OnLoadManager, Wexa.dialog instead of DialogManager, etc.
• WexaLogger is extended: numeric levels from 0 (most verbose) to 50 (critical only). Messages are shown when their level is >= the current logLevel.
• Improved request.js: JSON detection through Content-Type with silent fallback for non-JSON responses.
• Updated documentation and offline demos. Fixed license documentation to GFDL 1.3, except for slides. See: https://www.gnu.org/licenses/fdl-1.3.en.html for details.
• Added an "extra" JS package for slides. Currently proposed as a PoC.
