Koa is is largely based on Express, which in turn is based on Connect, a low-level middleware for creating Node.js Web applications.
Unlike those two aforementioned solutions, Koa's code doesn't include middleware within its core directly, but only provides the basic method for dealing callbacks, errors, external middleware loading, and so on.
So basically Koa is just the frame on which JavaScript middleware runs on, making the framework less error-prone and easier to maintain.
Since all middleware is loaded as modules it also makes the application's core code a lot less smaller, allowing developers to skip loading, executing and navigating through code they don't usually need.
