Installation

Step 1 - Install application

git clone https://github.com/prooph/proophessor-do.git into the document root of a local web server.

Step 2 - Install event store adapter

prooph offers two database adapters for prooph/event-store (at the moment). Pick the one you want to play with and install it via composer.

Doctrine DBAL Adapter

composer require prooph/event-store-doctrine-adapter

MongoDB Adapter

composer require prooph/event-store-mongodb-adapter

Step 3 - Configure Database

Before you can start you have to configure your database connection. As this is an example application for a CQRS-driven application we are using two different persistence layers. One is responsible for persisting the write model. This task is taken by prooph/event-store. And the other one is responsible for persisting the read model aka projections.

We've prepared a template for you. Just rename the config/dbal_connection.local.php.dist to dbal_connection.local.php and adjust configuration accordingly. Read on for more details.

Adapter Configuration

Tell the event store which adapter to use. To do so rename config/event_store.local.php.dist to config/event_store.local.php and uncomment the adapter that you have installed in Step 2.

Doctrine DBAL Adapter

If you uncomment the doctrine dbal adapter it will use the same dbal connection as the read model does. The required event_stream table is automatically created by doctrine migrations which you have to execute to create the projection tables too. Please see projection configuration for details.

MongoDB Adapter

If you uncomment the mongo db adapter you also need to rename config/mongo_client.local.php.dist to config/mongo_client.local.php. The MongoDB adapter will use a \MongoClient with default connection settings. But you can adjust the mongo client set up in the config file linked above.

Projection Configuration

Projections are persisted in SQL tables using Doctrine DBAL. The projections are independent from the event store adapter so you must set up a RDBMS (we suggest MySql) and adjust the doctrine.connection.default configuration which you can find in the dbal_connection.local.php.dist file.

Create An Empty Database

Before you can run the migrations you have to make sure that the database todo exists. You can of course use another name for the database but please align the doctrine.connection.default configuration accordingly.

Run Doctrine Migrations

To create the needed projection tables (and the event_stream if the doctrine event store adapter is installed) you should perform the migrations by running php bin/migrations.php migrations:migrate from the project root.

Note: We use a custom migrations script instead of the doctrine version because we're injecting the dbal connection provided by our IoC container.

Step 4 - View It

Open a terminal and navigate to the project root. Then start the PHP built-in web server with php -S 0.0.0.0:8080 -t public and open http://localhost:8080/ in a browser.

Note: You can also set the environmental variable PROOPH_ENV to development. That will forward exception messages to the client in case of an error. When using the built-in web server you can set the variable like so: PROOPH_ENV=development php -S 0.0.0.0:8080 -t public
