Generate application code in a worker

[Janpot]

Rough ideas on editor sandbox architecture

currently:

main thread => convert StudioDom to TSX code, stored in cache, signal sandbox service worker => convert cached code to ES5 to be runnable by the browser sandbox => HMR engine receive updates from main thread, reload changed modules through service worker

Future:

main thread => send StudioDom updates to worker thread worker thread =>

• maintain mirror of StudioDom
• keep up to date through small updates received from main thread
• generate application code, store in indexeddb
• signal serviceworker for updated files

serviceworker =>

• to serve files: read from indexeddb, convert files to ES5, (cache?)
• signal connected clients on updates

sandbox => HMR receive updates through serviceworker, reload changed modules, apply changes with react-refresh
