This Todo App is server rendered and client-hydrated React. This architecture is a lightweight alternative to NextJS, RemixJS, or other React metaframeworks with no compile or build step. The data is saved server-side in Val Town SQLite.

This "framework" is currently 44 lines of code, so it's obviously not a true replacement for NextJS or Remix.

The trick is client-side importing the React component that you're server rendering. Val Town is uniquely suited for this trick because it both runs your code server-side and exposes vals as modules importable by the browser.

The tricky part is making sure that server-only code doesn't run on the client and vice-versa. For example, because this val colocates the server-side loader and action with the React component we have to be careful to do all server-only imports (ie sqlite) dynamically inside the loader and action, so they only run server-side.
