Activity Pub for Go

Basic package for using ActivityPub API in Go.

It contains types for most of the ActivityStreams vocabulary and the ActivityPub extension. They are documented accordingly with annotations from the specification.

Usage

import "github.com/go-ap/activitypub"

Note about generics

The helper functions exposed by the package come in two flavours: explicit OnXXX and ToXXX functions corresponding to each type and, a generic pair of functions On[T] and To[T].

Before using them you should consider that the former comes with a pretty heavy performance penalty:
