Tusd
Tusd is a server implementation of the open protocol for resumable file uploads over HTTP. It functions as a gateway that streams incoming data directly to local disk or remote object storage backends, ensuring that large files can be processed without exhausting system memory.
The server is designed as a modular package that can be embedded directly into existing applications, allowing developers to integrate file transfer capabilities without requiring external service dependencies. It maintains persistent state for all active transfers, enabling clients to pause and resume uploads from the exact point of failure after network interruptions.
The platform supports a variety of storage backends and provides an event-driven hook system to trigger external scripts or network requests during the upload lifecycle. These hooks allow for custom validation of data and user credentials, as well as automated post-processing tasks, ensuring that all file transfers meet specific infrastructure and security requirements.
