Widgetsblokker

Widgetsblokker is a software concept referring to a component or module that governs the visibility and behavior of user interface widgets within a page or application. It can block, reveal, or delay widgets based on predefined rules or conditions.

The primary purpose is to improve performance, enforce design consistency, and enable controlled feature rollouts. It can also support accessibility checks by hiding widgets that fail certain criteria.

Typical implementations include front-end middleware or a widget registry that evaluates rules at render time. Rules may consider user authentication and roles, device capabilities, locale, or experiment groups, and can be configured statically or updated dynamically.

In practice, a widgetsblokker can be used in content management systems and web applications to gate non-critical widgets on mobile devices or during low-bandwidth periods, and to progressively load interface elements as conditions are met.

As a concept, it intersects with feature flags and access control, and some projects refer to it as component gating.

Drawbacks include added complexity, potential user confusion, and caching or performance overhead if evaluation is frequent.
