Troop

Full-featured, testable OOP

Wiki

Reference

Troop features

• multiple inheritance with traits
• makes use of ES5 property attributes
  • pseudo-privates are non-enumerable
  • constants are actually read-only
• testing mode for applying mock methods
• postponed, on-demand property definitions
• delegation of instantiation with surrogates
• support for instance memoization

Troop is distinguished from other OOP-related libs such as MooTools or Backbone by

• not littering your classes and instances with its own meta-properties
• non-declarative API leads to better IDE integration
• offering simpler unit testing with built-in mocks to speed up TDD process

Example

var MyClass = troop.Base.extend()
    .addPrivate({
        _secret: "ufo" // static private property
    })
    .addPublic({
        hello: "world" // static public property
    })
    .addConstants({
        pi: 3.14 // static public constant
    })
    .addMethods({
        init: function (who) {
            this.addPublic({
                hello: who
            });
        }
    });

var myInstance = MyClass.create("all");
