#Twitter client example with DDD

This is an experiment of create a Twitter's client with Behat following the DDD guidelines. The application is a standard API REST with an unique entry point for quering the ten lasts tweets for an user.

First, clone the repository git clone https://github.com/proclamo/twitter-client.git.

After, run composer.phar install.

Copy the configuration file cp app/config/parameters.yml.dist app/config/parameters.yml and edit vim app/config/parameters.yml with apropiate values. For these values, you have to go to https://apps.twitter.com/.

Set the right permissions in app folders.

After, run php app/console server:start.

The application is a standard API REST with an unique entry point at /tweets/[username][?limit=number_tweets]. You'll obtain ten tweets by default and twenty maximum. You can omit the username and you'll get a error message.

You can run behat tests executing bin/behat.

Domain Layer: src\Domain

Application layer: src\Application

Infrastructure layer: src\Infrastructure

Symfony integration: src\TwitterBundle

The Application layer could have been inside the TwitterBundle, but I've prefered to separate the DDD implementation for this layer and leave Symfony only the responsability of manage the REST layer. The serialization from domain entities to Json string could have been better managed by any bundle like JMSSerializerBundle but for demonstration/learning purposes I've prefered to have framework agnostic classes inside the Application folder. It's very easy to extend the functionality for example creating a Symfony Command for query the service.
