fuzzyioc

A "fuzzy" matching ioc container.

The vision

As suggested by @rinojohnsen;

An ioc container should "fuzzy" match dependencies to inject based on what members and method calls are used on the dependencies of a function.

Installation

npm install fuzzyioc

Run tests

npm test

Usage

var fuzzyioc = require('fuzzyioc');
 
var ioc = fuzzyioc();
ioc.register(Messages);
 
var view = ioc(View);
view.msg // "Yeah!"
 
function View (msgs) {
  this.msg = msgs.getMessageByKey("some.message.key");
}
 
function Messages () {
  var keys = { "some.message.key": "Yeah!" };
 
  this.getMessageByKey = function (key) {
    return keys[key];
  };
}

Todo

• Record number of parameters to function calls of dependencies. Use this to better match agains registered types.
• Follow assignments to this inside a function, so that a we can track usage (of this.something) along the prototype as well
• Track usage on the prototype
• Support singletons
