Hannibal
Hannibal is an experimental ActivityPub library for Go. It's goal is to be a robust, idiomatic, and thoroughly documented ActivityPub implementation fits into your application without any magic or drama.
There are other packages/frameworks out there that are more complete and mature. So please check out go-fed and go-ap before trying this.
Packages
Like the ActivityPub spec itself, Hannibal is broken into several layers:
pub - ActivityPub client/server
https://www.w3.org/TR/activitypub/
This is not an ActivityPub framework, but a simple library that easily plugs into your existing app. Add ActivityPub behaviors to your existing handlers, and send ActivityPub messages to
vocab - ActivityStreams Vocabulary
https://www.w3.org/TR/activitystreams-vocabulary/
This package includes the standard ActivityStream vocabulary, including names of actions, objects and properties used in ActivityPub.
streams - ActivityStreams data structures
https://www.w3.org/TR/activitystreams-core/
The stream package contains common data structures defined in the ActivityStreams spec, notably definitions for: Document, Collection, OrderedCollection, CollectionPage, and OrderedCollectionPage. These are used by ActivityPub to send and receive multiple records in one HTTP request.
This package also includes a lightweight wrapper around generic data structures (like map[string]any and []any) that makes it easy to access data structures within an ActivityStreams/JSON-LD document.
