Aurelia is a JavaScript web framework and component-based UI system used to build applications for browser, mobile, and desktop environments. It functions as a frontend application orchestrator and data binding library that synchronizes application state with the view to render dynamic content and process user input.
The framework implements a component architecture that pairs logic classes with HTML templates to create reusable visual elements. It utilizes a dependency injection container to manage object lifecycles and a modular composition model that aggregates independent functional packages into a single entry point.
The system manages the client-side user interface through observation-based data binding and template-driven DOM manipulation. It integrates components as custom elements to maintain compatibility with the native browser DOM hierarchy.
