As a low-level platform, Node.js offers a lot of flexibility in building the server side of web applications. In day-to-day work, all this flexibility means that there will be a lot of important decisions to make every time a new project is started. Hapi.js, a battle-tested configuration-centric framework for Node, takes the pain out of spinning up new applications so developers can focus on adding business value and creating great features. Hapi offers a super-clean model for building APIs, along with a powerful plugin system, so it's perfect for building individual services and for constructing entire applications.
