multiblob-http

multiblob-http is a Node.js library designed to serve content-addressed blobs over HTTP. It provides an HTTP handler, compatible with frameworks like Express, that exposes endpoints for retrieving blobs by hash (`GET /blobs/get/{id}`) and adding new blobs (`POST /blobs/add`). The library ensures efficient content delivery by setting appropriate HTTP headers, including `ETag` (based on the blob hash) and `Expires` (a year in the future), and supports HTTP range requests (RFC 7233) crucial for streaming media and partial content retrieval. The current stable version is 1.2.1, with releases appearing to follow a maintenance cadence, focusing on stability rather than frequent new features. Its primary differentiator is its tight integration with the `multiblob` package for backend storage and its robust handling of HTTP caching mechanisms for immutable, content-addressed data.
