frontendina

Frontendina is an open-source front-end framework and design system intended to support the development of interactive web user interfaces. It combines a component-based model with a declarative templating syntax and a reactive data layer to enable modular, maintainable code. The project places emphasis on accessibility, performance, and a coherent developer experience across teams.

Components are the basic unit of composition. State and props flow in a unidirectional manner, while a lightweight runtime reconciles changes to the DOM. The templating syntax allows developers to declare UI structure in a readable form. Styling is provided through a combination of CSS utility classes and optional scoped styling options. Built-in accessibility considerations include automatic ARIA roles, focus management, and keyboard navigation patterns. The framework ships with development tooling such as a dev server, a build pipeline, and testing utilities, and offers TypeScript support.

Frontendina's rendering model is designed to minimize DOM updates by computing diffs between the application state and the rendered output. It supports component lifecycles, composition, and reactivity through a minimal set of primitives. The framework can be integrated into existing projects and can be extended with third-party components and plugins.

Frontendina originated as an open-source project developed by a global community of contributors. It is distributed under an open-source license and maintained on a public repository with community governance. The ecosystem includes a library of UI primitives, example apps, and tutorials, and is used in various web projects to standardize UI development practices.
