The record

Purpose: Mitosis is an open-source tool that transforms JSX components into components for multiple frameworks.
Framework outputs: The overview lists Angular, React, Qwik, Vue, Svelte, Solid, and React Native as supported outputs.
Web component outputs: Mitosis can generate Lit, Stencil, and raw web components.
How it works: Mitosis parses a static subset of JSX into a JSON structure that can be serialized into different frameworks.
Figma integration: Mitosis works with Builder.io Fusion to turn selected Figma layers into code that can be adapted to selected frameworks.
CLI: The CLI provides `mitosis build` for projects or folders and `mitosis compile` for compiling one component file to one target.
Configuration: A `mitosis.config.js` file can specify compilation targets, output directory, files, exclusions, and generator options.
Custom targets: The configuration documentation lists targets including React Native, Swift, HTML, Vue, React, Svelte, Solid, and Qwik.
Getting started: The quickstart creates a project with `npm create @builder.io/mitosis@latest` and initially offers React, Svelte, and Qwik output selections.
Developer support: The documentation links to a Mitosis community Discord for questions and participation.
Intended use: The overview describes maintaining a shared design system across frameworks, publishing it to npm, and building cross-framework SDKs as use cases.
What it does: Mitosis transforms JSX components into components for multiple frameworks.
Output targets: The quickstart lists targets including React, Vue, Angular, Svelte, Qwik, React Native, Swift, Lit, and Web Components.
Key features: Mitosis components can use state through the useStore or useState hooks, and components update when state changes.
