Bearcat -- a POJOs based application framework

Bearcat is a POJOs based application framework which provides a lightweight container for writing simple, maintainable node.js. Bearcat provides an infrastructural backbone to manage business objects so that developers can focus on application-level business logic. Bearcat enables you to build applications from "plain old javaScript object"(POJO) and to apply enterprise services non-invasively to POJOs.

###Simple POJOs + Configuration metadatas = Elastic, maintainable system

Build Status

Features

lightweight container

  • Dependency injection implementated Inversion of Control (IoC) to manage POJOs
  • AOP based declarative middleware services
  • Consistent development and configuration

Easy

  • Simple meta configuration and POJOs
  • Lightweight: high development efficiency based on node.js
  • Reuseable: POJOs can be used to any development environment
  • Invasive: there's no dependence on a container API
  • Modular: you just use only those parts that you need
  • One stop shop: no need for a dedicated Singleton or factory for every object etc

Powerful

Extensible

  • Custom features: you can add custom codes to container

What is POJO ?

POJO is an acronym for Plain Old Java Object, you can refer to POJO wikipedia. It is mostly used in Java Platform which is used to emphasize that a given object is an ordinary Java Object, not a special object.
In Node, what is POJO ?
It must be Plain Old JavaScript Object, which is simple, ordinary, and not anonymous.
To be not anonymous, it must have Constructor function.
So POJO can be like this:

var POJO = function() {
	this.props = null;
}

POJO.prototype.method = function() {
	
}

module.exports = POJO;

Why should we use POJO ?

  • POJO is simple, everyone can write it
  • POJO makes development consistently, all your codes is POJOs
  • POJO makes it friendly to document

Usage

Running bearcat is quite simple, all you have to do is to write simple POJOs and simple configuration metadatas like context.json, after this, passing context.json paths to bearcat, and run it, then all your POJOs will be magicly turned into an elastic, maintainable system.

var Bearcat = require('bearcat');
var contextPath = require.resolve('./context.json');

var bearcat = Bearcat.createApp([contextPath]);
bearcat.start(function(){
   var helloBearcat = bearcat.getBean('helloBearcat'); // get bean
   helloBearcat.hello(); // call the method
});

Codes written by simple POJOs and simple configuration metadatas can be run without Bearcat, however, in this case, you should have to do a lot of things by yourself, like handling dependency, configuration

more bearcat apis can be refered to bearcat-api
