@filepack/core

Framework-neutral Filepack lifecycle, route, authorization, error, and adapter contracts.

pnpm add @filepack/core

The main export provides createFilepack, route, the Web-standard handler, stable errors, domain types, and the ObjectStorage and FileRecordStore contracts. Adapter packages use runner-neutral contract cases from @filepack/core/testing.

const filepack = createFilepack({ routes, storage, records });
const handler = filepack.handler({
  auth: async (request) => getActor(request),
});

export const { GET, POST, PUT, DELETE } = handler;

See the repository API reference for the approved direct lifecycle surface. Terminal attempts use trusted zero-byte object markers and durable settlement cleanup. M5A adds safe upload status, bounded part preparation and receipt recording, server-side multipart completion, and durable abort cleanup. @filepack/client provides browser pause, cancellation, progress, and multipart reload recovery.
