About the project

Social Graph API (SGA) was built on top of Play! Framework.

You can see a live demo deployed at Heroku.

Authentication

SGA uses Silhouette with the JWTAuthenticator (Json Web Token) to secure the API. To save the data of the authentication layer uses Redis.

Social Graph Store

SGA uses Neo4j as a graph store. As a Scala client library uses AnormCypher.
