Loopback is a node.js framework that is built on top of express.js. The Strongloop's developers created Loopback to help node.js developers cutting amount of code they need write when creating API which does CRUD or Auth. We can think that using loopback is like we are using Express with Steroids and it is worth to moving from Express to Loopback in case we are developing the Backend of Mobile Application which is usually does not have complex logic inside.
