Lona

Lona is a framework and set of utilities designed to synthesize centralized design definitions into cross-platform UI code, visual artifacts, and motion assets. It functions as a design system generator that converts a single set of specifications into native code for multiple operating systems, Sketch files, and other visual outputs.

The system includes a motion design renderer that integrates motion files and renders them into video files to maintain consistent animation experiences. It also features a design artifact exporter for generating localized screenshots and bulk image exports based on predefined design system definitions.

The project covers a broad range of design workflow capabilities, including design system management for components and styles, visual component prototyping through a graphical interface, and data-driven design previews to validate layout accuracy. It utilizes a headless engine and an intermediate representation model to process structural layout definitions independently of specific graphics libraries.

Features

Design Systems - Defines a standardized data format for specifying components, colors, text styles, and shadows.

Schema-Driven Code Generators - Transforms standardized design system data into platform-specific UI code using template-based synthesis.

Design System Engines - Implements a headless engine to process structural layout definitions and style rules independently of any platform.

Intermediate Representations - Translates raw design definitions into a common internal format to ensure consistent cross-platform rendering.

Cross-Platform UI Frameworks - Maintains consistent visual styling across different operating systems through a single set of design specifications.

Design System Generators - Converts centralized design definitions into cross-platform UI code, Sketch files, and visual artifacts.

Design System Management - Centralizes components, colors, and text styles in a standardized format as a single source of truth.

Cross-Platform UI Frameworks - Provides an API to convert design definitions into native UI code for multiple operating systems.

Multi-Format Design Exporters - Converts shared design specifications into diverse outputs including native code, Sketch files, and image assets.

Design-to-Image Exporters - Provides a command-line utility for bulk export of localized screenshots and images from design definitions.

Motion-to-Video Pipelines - Converts animation definitions through a processing sequence into final video assets for consistent motion experiences.

Animation and Motion Systems - Integrates motion files and renders them into video to ensure a consistent animation experience.

Design Asset Export Managers - Automates the export of localized screenshots and bulk image assets based on design specifications.

Interactive Design Previews - Uses real information from data files or interfaces to validate the visual accuracy of UI layouts.

Video Renderers - Provides a pipeline that renders motion design files into video assets to ensure consistent animation experiences.

Animation Workflows - Integrates motion files and renders them into video to maintain visual consistency across user interfaces.

Data-Driven Layouts - Allows populating UI components with external data files to validate visual accuracy during layout preview.

Visual Component Builders - Provides a graphical interface for building component systems and mocking up screens across various layout sizes.

Visual Interface Prototyping - Enables building component systems and mocking up screens via a graphical interface to test layouts.
