Eliminating Callback Hell

About This Space

This is a simple demo of Fibers! Fibers simplifies code by avoiding messy code known as "callback hell", "promises hell", or "async/await hell". Once Fibers is setup, you never have to think about callbacks or promises (they are handled automatically for you).

Eliminating Callbacks

This space is a demonstration of using Fibers, which allows you to call asynchronous functions without callbacks. This can significantly simplify development and code maintenance. In this example, the README.md file is read from the file system using only 1 line of code thanks to Fibers. The benefits of this approach multiply considerably as your application grows and more code is written.

How to use Fibers

With NodeRun, using Fibers is easy. NodeRun includes Profound.js API that automatically create Fiber-enabled functions out of any asynchronous Node.js function, API, or set of API. You can call the new functions with the same ease as calling synchronous API; however, the processing is still asynchronous and the Node.js event loop is never blocked. NodeRun also provides many of its own API that are already Fiber-enabled, making it easy to work with databases, Web Services, and Web/Mobile interfaces.

API

pjs.wrap() - Wrap an asynchronous function so that it can be called in a top-down manner without a callback
