1# SSR React Mini & SQLite Todo App
2
3This 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](https://docs.val.town/std/sqlite/).

7## SSR React Mini Framework
8
9This ["framework"](https://www.val.town/v/stevekrouse/ssr_react_mini) is currently 44 lines of code, so it's obviously not a true replacement for NextJS or Remix.
10
11The trick is [client-side importing](https://www.val.town/v/stevekrouse/ssr_react_mini?v=53#L30) the React component that you're [server rendering](https://www.val.town/v/stevekrouse/ssr_react_mini?v=53#L35-37). Val Town is uniquely suited for this trick because it both runs your code server-side and exposes vals as [modules](https://esm.town/v/stevekrouse/TodoApp) importable by the browser.
12
13The 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`](https://www.val.town/v/stevekrouse/TodoApp?v=246#L7) and [`action`](https://www.val.town/v/stevekrouse/TodoApp?v=246#L20), so they only run server-side.
