Cotomy v1.0.0

First stable major release. Establishes Cotomy as a production-ready foundation for business web applications.

Overview

Cotomy v1.0.0 is the first stable major release. It marks the transition from experimental work to a production-ready foundation for business web applications.

Cotomy focuses on practical, server-oriented development where HTML, CSS, and TypeScript are treated as a single cohesive unit. It is designed for internal tools, management systems, and line-of-business applications rather than UI demos.

Version 1.0.0 does not mean feature completeness. It marks design model stabilization. The stabilization refers specifically to Cotomy’s core runtime and structural model as described in the official reference (Cotomy Reference ).

What v1.0.0 Means

The API surface is now considered stable, core design principles are finalized, breaking changes will be minimized going forward, and the release is suitable for long-term adoption in production systems.

This release establishes Cotomy’s core architecture as the baseline for future evolution.

Core Philosophy

The core philosophy is simple: one screen equals one endpoint, HTML is the primary structure rather than a virtual DOM, CSS is scoped at the component level, TypeScript controls behavior rather than rendering, and the model is designed for server-backed business systems.

Cotomy is not a SPA-first framework. It is optimized for structured, maintainable, data-driven enterprise UI.

Key Capabilities

Key capabilities include component-scoped CSS, strong TypeScript integration, declarative DOM handling, event delegation utilities, form and screen controller patterns, and coexistence with Razor Pages and server rendering.

Who Should Use Cotomy

Cotomy is ideal for:

internal business systems, ERP and management tools, admin dashboards, form-heavy applications, and systems where HTML structure matters.

Not intended for:

animation-heavy consumer apps, Canvas or WebGL UIs, and highly interactive design-first products.

Stability Notice

Version 1.0.0 establishes Cotomy’s stable baseline. Future versions will focus on ecosystem expansion, tooling, and developer experience rather than core architectural shifts.
