The problem • Projets with short delivery time (<1 month) • Repetitive back-end code • Lack of front-end integration standards

Backend as a Service • baasbox/baasbox - Java • deployd/deployd - NodeJS / MongoDB • hoodiehq/hoodie.js - NodeJS / CouchDB • parse.com - Closed source / $$$$$ • doubleleft/hook - PHP / MySQL

hook • REST API • Data persistance (CRUD) • MySQL / PostgreSQL / MSSQL / MongoDB • User authentication • Extensible

Installation • Dependencies: PHP 5.5+ / node 0.12+ • github.com/doubleleft/hook $ curl -sSL https:// raw.githubusercontent.com/ doubleleft/hook/master/scripts/ install.sh | bash
