Forks on CodeSandbox will ignore
/index.html
and create their ownpublic/index.html
which leads to broken sandboxes in CodeSandbox.Compare a forked sandbox from
main
vs forked sandbox from this branchWe now throw if
/index.html
is used and only usepublic/index.html
throughout the codebase which works both in Sandpack and CodeSandbox.This also means we're consistent. Some sandboxes were already using the functioning
public/index.html
e.g. https://react.dev/reference/react-dom/client/hydrateRoot#hydrating-server-rendered-html.
