Inject by Spredfast. What is dependency injection? In a traditional dependency injection paradigm, the container manages objects that are connected to each other through the wiring spec. Injection is done by either setting properties or passing values to a constructor function (which typically then sets the properties on the object itself). While that is a paradigm that works well in object oriented languages, it's more natural in a functional language like JavaScript to inject functions instead. NOTE: inject-core.js can be used independently of JavaScript MVC. You obviously wont be able to use the Class and Controller based functionality, but named functions and everything else should work.
Advantages of injecting functions instead of objects Why an injector? JMVC Inject is inspired by AMD. Dependencies are clearly defined.Avoid global variables.Identifiers can be remapped easily, so you can swap out implementations. New Features To create an injector, call Inject with the inject and dependency definitions. Spredfast/JMVC-Inject. Inversion of Control Containers and the Dependency Injection pattern. In the Java community there's been a rush of lightweight containers that help to assemble components from different projects into a cohesive application. Underlying these containers is a common pattern to how they perform the wiring, a concept they refer under the very generic name of "Inversion of Control".
In this article I dig into how this pattern works, under the more specific name of "Dependency Injection", and contrast it with the Service Locator alternative. The choice between them is less important than the principle of separating configuration from use. One of the entertaining things about the enterprise Java world is the huge amount of activity in building alternatives to the mainstream J2EE technologies, much of it happening in open source. Underlying these containers are a number of interesting design principles, things that go beyond both these specific containers and indeed the Java platform.

Inversion of Control. IOC · cujojs/wire Wiki. Inversion of Control Inversion of Control (IOC) is a general principle of software architecture, that can be applied in different ways. The Wikipedia article on IOC says it is where "the flow of control of a system is inverted in comparison to procedural programming. " That's one of those definitions that's more useful after you already understand IOC, and not as useful when you're trying to figure it out in the first place. It basically says that IOC is in effect in some form in any system where control is inverted from what is "normal" is.
If you write Javascript in a browser environment, you're already using one form of IOC. Normal Control Example Take a simple program, like a shell script, that executes sequentially from beginning to end, maybe reading files, transforming the data, and then outputting the transformed data to stdout or another file. That's a traditional, or "normal", flow of control. Inverted Control Example Dependency Inversion Abstractions A Simple Example. OSCON 2005 - Dependency Injection - Thank You!
