componentsit

Componentsit is a conceptual framework and set of conventions for building modular, reusable user interface components intended to be composed into applications across web, mobile, and embedded platforms. It aims to enable interoperability between components developed in different languages and frameworks by defining a common component model, data flow, and packaging format.

Core concepts include explicit component interfaces, property passing, internal state, event handling, and a declarative rendering model. Components are designed for composition through containment and higher-order constructs, rather than inheritance. A component registry provides discovery, versioning, and dependency management, while a standardized metadata scheme guides naming, licensing, and compatibility.

Architecture and interoperability: a platform-agnostic runtime can render components in multiple environments, with an interface description language describing component contracts. A messaging or event bus supports communication across boundaries, and styling uses a shared design token system or theming convention. Packaging follows a modular module format with clear scoping and isolation guarantees.

History and use: componentsit emerged in discussions of cross-framework UI interoperability in the early 2020s as an aspiration rather than a formal standard. It has seen experimentation in open-source projects and some large-scale organizations as a way to organize UI assets and enable reuse, but has not achieved universal adoption.

Criticism and challenges: proponents cite the potential for reduced duplication and smoother cross-platform development; critics point to fragmentation risk, added complexity, performance overhead, and the difficulty of aligning multiple ecosystems around a single model.
