Mitosis is a cross-framework compiler that transforms a single JSX-based source into native components for multiple frontend libraries simultaneously. It functions as a multi-target UI library builder, allowing developers to maintain a single source of truth for design systems while generating production-ready code for diverse environments including React, Vue, Angular, and Svelte.
The system operates by parsing unified component code into an intermediate JSON representation, which serves as the foundation for all downstream framework generators. This architecture utilizes a visitor-based transformation process and a plugin-driven serializer model, enabling developers to inject custom logic, normalize lifecycle hooks, and apply target-specific formatting rules to ensure consistent behavior across different platforms.
The compiler supports a broad range of development requirements, including reactive state management, content slotting, and styling strategies. It provides mechanisms for design system synchronization, allowing for the integration of tokens from external design tools, as well as the ability to define framework-specific implementation overrides when unique library dependencies or platform requirements arise.
The tool is managed via a command-line interface that handles build target configuration and JSX transpilation. It is designed to be extensible, allowing users to hook into the compilation pipeline to modify component metadata or extend framework support through custom serializers.
