Async Error Handling in Composables
try/catch in async composables, error state exposure, retry logic in useFetch.
Errors in Async Composables
Composables that fetch or run async work need their own error strategy. The pattern: expose an error ref so consumers can react, while the async function catches failures internally.
Exposing an error Ref
Return an error ref alongside data and loading. Consumers watch it to show messages.
function useApi() {
const data = ref(null);
const error = ref(null);
return { data, error };
