Simulacrum is a React component that you can use as a code-playground. It comes with its own IDE, compiler and surprisingly a runtime as well.
Simulacrum relies heavily on Vite to bundle and pack things into a neat package. This includes taking care of web-workers for the compiler and layout-engine, which we will be covering later.
This is handled by Storybook. There are a few stories added already to cover basic functionality.
