jQuery.whenSync() Plugin For Chaining Asynchronous Callbacks Using Deferred Objects
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

Last week, I started to talk about chaining asynchronous Validation rules using jQuery Deferred objects . After writing up that post, I thought I might be able to factor-out the core idea into its own jQuery plugin - jQuery.whenSync(). Like the native jQuery.when() method, the jQuery.whenSync() method takes a variable-number of argument ... Read More »

ColdFusion Supports HTTP Verbs PUT And DELETE (As Well As GET And POST)
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

Over the weekend, I read an excellent book on building RESTful web services - the REST API Design Rulebook by Mark Masse . In the book, Masse describes how the various HTTP methods (also known as Verbs) are intended to be used to create, access, update, delete, and augment data within a RESTful web service API. As far as HTTP verbs go, I'm extremely familiar with GET and POST - the two ve ... Read More »

REST API Design Rulebook By Mark Masse
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

Over the weekend, I read The REST API Design Rulebook by Mark Masse . I absolutely loved this book! In a world where so many computer science questions are answered with, " It depends ," or, " there's no 'right' answer ," Masse comes through with a book that says, No, these are the rule ...

Use A Return Statement When Invoking Callbacks, Especially In A Guard Statement
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

In a synchronous processing workflow, the Return statement tends to indicates the end of a given function's execution. In an asynchronous processing workflow, callbacks are more generally used to indicate the desired end of a given function's execution. That said, it is critical that a Return statement is also used in an asynchronous workflow in order to ensure that multiple callbacks are not invoked accidentally. This is a mistake that I have made many times and it always comes back to bite ... Read More »

Using jQuery Deferred To Chain Validation Rules In An Asynchronous, Non-Blocking Environment
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

A while back, I blogged about how client-side validation is changing the structure of server-side validation ; with the client creating user-friendly error messages, the server can finally streamline its validation and data processing using a light-weight, exceptions-based workflow. While I really like this evolutionary step in data handling, I realize ... Read More »

How I Got Node.js Running On A Linux Micro Instance Using Amazon EC2
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

In the past, I've dabbled with Node.js (a server-side JavaScript runtime environment) on my local MacBook Pro. If you know JavaScript, it's not too hard to get something up and running on your local machine. Putting Node.js out into the wild, however, is whole other beast. Not only am I mediocre at managing web servers in general, I happen to know almost nothing about Amaz ... Read More »

Extending Classes In A Modular JavaScript Application Architecture Using RequireJS
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

Yesterday, I tried to apply some deep thinking to how dependencies should be managed in a modular JavaScript application architecture that is using RequireJS . The conclusion that I came to was that RequireJS should manage and load "definitions" while your application should manage and load "instances." This makes sense since instantiation is the domain of your business ... Read More »

Managed Dependencies vs. Dependency Injection In RequireJS
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

In my journey towards understanding modular JavaScript application architecture, I've been using a lot of RequireJS . The RequireJS framework facilitates the organization and then the subsequent loading of in ... Read More »

Creating A Keyboard-Shortcuts Module In A Modular JavaScript Application
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

Last week, I looked at handling keyboard shortcuts in a modular JavaScript application architecture . In that initial exploration, I distributed the handling of keyboard shortcuts across two different modules: a Controller module and the View module that would ultimately be affected by the command. After I was done with the code, however, I was left ... Read More »

Handling Keyboard Shortcuts Within Modular JavaScript Application Architecture
» ‎ Ben Nadel ColdFusion And Web Development Feed @ BenNadel.com

Yesterday, when using Gmail, I started to think about keyboard shortcuts. Specifically, I started to think about how keyboard shortcuts get routed within a modular JavaScript application architecture. If I have a module that can respond to the keyboard - but, that module is not supposed to "know" about the document at large - how does it listen for key-based events? I can think of two ways: 1) Either the application listens for keys and then directly invokes methods on encapsulated modules; o ... Read More »
