Riot is a component-based library for building user interfaces through modular, single-file components. It functions as a framework for creating reusable elements that combine markup, logic, and scoped styles, which are then compiled into standard JavaScript functions for browser execution.
The library distinguishes itself by utilizing direct rendering, which updates the document object model by tracking state changes without the overhead of a virtual representation. It supports server-side rendering and hydration to improve initial page load performance and search engine indexing. Developers can extend the core functionality through a global plugin system and integrate custom preprocessors into the build pipeline to support alternative syntax or languages.
The project provides a comprehensive set of tools for managing component lifecycles, state, and user interactions. It includes capabilities for conditional rendering, dynamic collection generation, and scoped style encapsulation to prevent style leakage. The system also offers command-line tools to bootstrap project structures and bundle assets for deployment.
