It's a tool for building scalable, secure Node.js server applications.
Most of the time, a web app has some CRUD functionality as its base. Eicrud attempts to abstract this into a simple and easy-to-use API, so you don't have to re-write boilerplate code (controllers, validations, db queries...) whenever you need a new service. By centering everything around CRUD entities, Eicrud provides a framework for writing complex applications that are easy to read, test, and maintain. Eicrud also emphasizes "default security" for its components, where everything is forbidden until allowed.
