JavaScript for Line of Business Applications

JavaScript has grown from a webpage toy to being used in large-scale deployments both on the server and in the browser. This rapid growth has outpaced the growth of the language itself, which lacks features that allow teams to communicate requirements and build applications safely. This session will describe TypeScript, a modern superset of JavaScript built for the needs of modern JavaScript development. We'll explore features in the language and demonstrate how these features work together with tooling to avoid common pitfalls and enable a pleasant developer experience.

Developers creating JavaScript applications these days usually use a combination of MVC, modules, widgets and plugins for their architecture. They also use a DOM manipulation library like jQuery.

Whilst this works great for apps that are built at a smaller-scale, what happens when your project really starts to grow?

In this talk, I present an effective set of design patterns for large-scale JavaScript (and jQuery) application architecture that have previously been used at both AOL and Yahoo amongst others.

You'll learn how to keep your application logic truly decoupled, build modules that can exist on their own or be dropped into other projects and future-proof your code in case you need to switch to a different DOM library in the future.

Use a T4 template to generate Knockout-viewmodels based on .NET classes.

This article describes a solution to this problem by using T4 templates to generate the JavaScript Knockout models automatically based on the .NET classes. The resulting Knockout models are extendable so as to be able to add additional functions and (computed) properties client-side. Finally, I also added an IsDirty feature that can indicate if the model has been modified since it's data was set.

Cargo-cult programming is what a programmer does when he or she doesn't know a particular language or paradigm well enough, and so ends up writing redundant and possibly harmful code. It rears its head quite often in the land of JavaScript. In this article, I explore the concept of cargo-cult programming and places to watch out for it in JavaScript.

Cargo-culting is sometimes defined as "the extreme adherence to the form instead of content." The form, in programming, being the syntax, paradigms, styles and patterns that we employ. The content being the abstract thing that you are seeking to represent through your code — the very substance of your program.
