useCourierFile uploads with real progress

A headless React hook and Vue composable with XHR progress tracking, retries, cancellation, and chunked uploads for large files.

Real upload progress
Built on XMLHttpRequest instead of fetch, so you get real 0-100% progress events fetch can't give you.
Retries and cancellation
Retry a failed upload or cancel one in flight, with lifecycle callbacks to hook in your own side effects.
Chunked uploads for large files
Files too big for a single request are split into sequential chunks, each retried independently on failure.
Headless and typed
No UI, no styling opinions — bring your own components, in React or Vue. Fully typed API with generics for your response shape.
