Reahl is a web application framework focused on reusable application components and a high-level description of user interfaces. Developers work with component abstractions instead of manually coordinating the individual web technologies that render those components in a browser.
The project includes Reahl-web, which provides the web application layer, and Reahl-component, which supplies infrastructure for components in broader applications. Components can carry configuration, internationalisation and their own data-model requirements. This makes the framework particularly relevant where an application is assembled from separately maintained functional modules.
Instead of treating a web page as an unrelated collection of handlers, Reahl organises interaction around widget objects and component responsibilities. A widget can contribute both a visual representation and the logic needed to process input, which helps separate application modules remain reusable.
This is free and open source software.
Key Features
- Reusable widgets represent interactive parts of web pages.
- Component infrastructure supports modular application organisation.
- Forms connect input fields, events and validation rules.
- Page layouts can be constructed from nested interface components.
- Database integrations enable persistent application state.
- Component-level configuration supports reusable functionality.
- Internationalisation infrastructure supports translated user interfaces.
- Application event handling connects browser actions to server logic.
- Framework abstractions hide repeated low-level web integration code.
- Testing utilities support component and application development.
- Parameterised widgets can present related interfaces with different data.
- Event handlers respond to actions associated with form and page controls.
- Reusable components package configuration alongside interface behaviour.
- Component schemas can describe persistent data required by a module.
- Validation and error display can be coordinated with the associated widget.
