A middle tier framework for javascript#What's a middle tier framework?
A middle tier framework is code that facilitates creating business logic in a reusable, extensible, maintainable, and testable manner. It promotes creating business logic that is completely decoupled from its consuming technologies and helps to ensure that separation of concerns (SoC) are adhered to.
#####peasy-js offers/addresses the following:
- Easy to use business and validation rules engine
- Scalability
- Reusability (decouples business and validation logic from consuming code and frameworks)
- Swappable data proxies
- Multiple client support
- Multiple deployment scenario support
- Easy testability
- AMD, Browser, and CommonJS support
- Zero dependencies
#Why peasy-js?
Because the javascript ecosystem changes at a pace much more rapid than your business logic. UI frameworks change: Backbone one day, Angular the next day, React the following... Backend frameworks change: Express one day, Koa the next day, Hapi the next... Data frameworks and ORMS change...
Why couple your code with technologies that are hot today and gone tomorrow? Why not focus on your business logic and abstract out everything else into truly reusable code that can be consumed by javascript in the browser, backend, or both, and by any UI or backend framework?
peasy-js makes it trivial to whimsically swap out UI, backend, and data frameworks in your applications by creating your business logic in a composable, reusable, scalable, and testable manner.

#Getting started
You can get started by reviewing the walk throughs below.
An additional sample can be viewed here that showcases creating a business service, custom command, business rules, and wiring them up. The sample also showcases how to consume the service. To see it in action, run: node src/sample.js from a command line.
An entire middle-tier implementation using peasy-js can be viewed here. This sample application is a ficticious order entry / inventory management system web api.
For additional help, be sure to checkout the wiki as it covers in-depth how-to's, general framework design, and usage scenarios.
