API Platform ActivityPub

⚠️ This project is highly experimental, it isn't suitable for production yet ⚠️

API Platform ActivityPub is a bundle for the API Platform framework and Symfony providing support for the ActivityPub protocol and for the ActivityStreams vocabulary.

The ActivityPub protocol is a decentralized social networking protocol. It provides a client to server API for creating, updating and deleting content, as well as a federated server to server API for delivering notifications and content.

API Platform ActivityPub allows to easily add support for ActivityPub to new or existing API Platform projects, while still being able to benefit from all API Platform features (yes, including Mercure, Vulcain and GraphQL!)


Install API Platform or Symfony

If it's not already done!

Install the Bundle

composer require api-platform/activity-pub

Generate the ActivityPub Entities

Install API Platform Schema Generator:

composer require --dev api-platform/schema-generator

Alternatively, you can download the PHAR version.

⚠️ Currently, this development version must be used to generate the schema

Then generate the entities:

../schema-generator/bin/schema generate src vendor/api-platform/activity-pub/build/schema.yaml

If you want to tweak the generated files, copy and adapt the provided configuration file. The generation is a one time operation, then you can edit the entities to fit your need and remove api-platform/schema-generator.

Configure Doctrine, API Platform and Symfony

See the test configuration in tests/app/index.php
