Lightningâ„¢ is an open-source WebGL/JavaScript-based UI framework that enables anyone to build high-quality TV apps with great performance. This framework has been specifically built to enable high-quality UI rendering on lower-end set-top boxes with memory constraints.
Lightning apps outperform HTML5 apps when compared to those built on other UI frameworks/libraries like React, Redux, Pixi.JS, etc. Lightning also enables additional performance gains by relying on WebGL and Canvas2D instead of DOM elements.
Characteristics
Optimized for big screens and works on most browsers with a cross-WebGL based framework
Great performance, even on low end set-top boxes
Fast rendering and loading
Efficient memory management
Advanced garbage collection mechanism
Development
Innovative, fast, and high code quality development principles that aid in drastically cutting down development time
Develop and test on your local browser or on a Comcast device
Simple learning and adoption, as well as easy bundling to use the same app for other Pay TV/OEM platforms
Features
Application framework
Render tree (WebGL or Canvas2d)
Animations toolkit for advanced transitions/visual effects
Keypress-based input/focus handling
Special effects, custom shaders
Pre-integrated with the Firebolt requirements
Technical Highlights
Component-based, to help you split up your app in a clean way
Static templates that offer great overview and fast spawning
Doesn’t use Virtual DOM, in contrast to other frameworks
Patching allows convenient Virtual DOM-like patterns without the downsides
State Oriented Programming enforces robustness in reactive components
Signals and commands provide easy-to-use inter-component communication
