About blossy
Blossy is a Go framework for building customized Blossom servers. It provides functional options for settings including hostname, logger, and HTTP range support, and Hooks to inject custom functions for connection handling, blob upload and download flow, and rate limiting.
It does not include a default database. Developers must supply their own storage, with community implementations such as blisk available to store blobs on disk with metadata in SQLite.
Key features
