Event Store Client for async TCP connections

v1.0.0-RC-1 2019-07-21 21:21 UTC


PHP 7.4 Event Store Client Implementation.

Build Status Coverage Status Gitter


Prooph Event Store Client supports async non-blocking communication via TCP to EventStore.

The EventStoreConnection maintains a full-duplex connection between the client and the Event Store server.


The protobuf extension from Google is recommended, however it is not required.

When this extension is missing, the client will fallback to use google/protobuf installable via composer.

The extension allegro/php-protobuf is not compatible.

Additional extensions are only needed if your app necessitates a high numbers of concurrent socket connections.



You can install prooph/event-store-client via composer by adding "prooph/event-store-client": "dev-master" as requirement to your composer.json.


Using docker:

docker run --name eventstore-node -it -p 2113:2113 -p 1113:1113 eventstore/eventstore

Please refer to the documentation of

See server section.

In the docker-folder you'll find three different docker-compose setups (single node, 3-node-cluster and 3-node-dns-cluster).

Quick Start

For a short overview please see the examples folder.

Unit tests

Plain PHP

Run the server with memory database

Note: This is the start-script of the Event Store database, not something provided by this library!

./ --run-projections=all --mem-db

You need to ignore the ignore group

./vendor/bin/phpunit --exclude-group=ignore

Those are tests that only work against an empty database and can only be run manually.

Before next run, restart the server. This way you can always start with a clean server.
