You should use events, but not for signaling ready! Ready implies state, and once you are ready, you stay ready. This is a module for everyone who has bound an event handler.on('ready', function() {}) that doesn't execute because you added the handler after the 'ready' event already fired. ## Warning If you use this mixin, you must have 'ready', '_ready', and '_readyCallbacks' available on your class. Ready will stomp on these variables if you're trying to use them in your class. ## Example ```javascript var ready = require('ready'); // example class that uses Ready function MyClass() { this.someProperty = 'some value'; } ready.mixin(MyClass.prototype); // Normal class prototype functions MyClass.prototype.doSomeWork = function() {}; // Create a new class that uses ready mixin var myClass = new MyClass(); // Add callback for when myClass is ready myClass.ready(function() { console.log('I am now ready'); }); myClass.doSomeWork(); // We are now ready, fire callbacks! myClass.ready(true); // Adding a new callback once we're already ready gets executed immediately myClass.ready(function() { console.log('I came late to the party, but I will still execute.'); }); // Ok, you can set the ready state to false now as well... for whatever reason myClass.ready(false); myClass.ready(function() { console.log('I will not fire until you set ready to true again.'); }); ``` ## License [MIT](LICENSE)
