Philosophy 🧠

XSWRuses two new approaches compared to other data fetching libraries like swr or react-query:

  1. Encapsulating key+fetcher+params in a single abstraction called schema.
  2. Composing features with very simple hooks instead of having bloated configuration and unexpected behaviors.
