JavaScript for Line of Business Applications

pager.js is a JavaScript library based on KnockoutJS and jQuery that provides the possibility of creating single page applications in a declarative fashion - nesting subpages inside subpages where each subpage can be developed standalone but still communicate between each other.

This makes it easier to design very large scale single page web sites.

Introducing Lavaca, the open source, HTML5 application framework by Mutual Mobile. Jumpstart development of your project by basing them off of Lavaca and using Lavaca's build tools.

Lavaca features:A build system supporting multiple configurations for different environmentsAn HTML, JavaScript, and CSS packaging and minification systemA JavaScript documentation generation systemA unit testing frameworkA JavaScript MVC frameworkA templating frameworkA translation framework…as well as many other essential components for modern web applications.

Lavaca has a ton packed into it, and is designed to work well as a cohesive whole, while still remaining lightweight. Lavaca is built with extensibility in mind and allows you to easily extend components and build your own on top of its framework.

It’s likely that you’ve used classes and interfaces in statically typed languages to organizing your code into logical units. When you work with JavaScript these constructs do not exist...

I have written about the concept and the tool for complexity analysis of JavaScript code before. In addition to that complexity monitoring strategy, apparently it is also useful to produce the so-called complexity report. Fortunately, now we a visualization tool which allows us to prepare such a report.

There are some ready-to-enjoy exemplary Plato reports, such as the one for jQuery. The summary page, as shown below, is useful to give a quick comparison of the different source files, in terms of code complexity, lines of code (LOC), etc.

So what do you do if you don’t want to build a single page application? While working at a customer I came across ROCA (Resource-oriented Client Architecture) which is a set of rules for a web application architecture. It’s a short list, so before I repeat them here, please read them there.

Ready?

So now you know the rules, but that doesn’t mean you can instantly imagine how such an application would look like. At least I couldn’t. I learned that there are two important aspects:

The JavaScript IntelliSense extensibility feature enables you to customize IntelliSense results in the JavaScript editor for third-party libraries. This can improve the experience of developers who use these libraries.

The JavaScript language service provides IntelliSense features for third-party JavaScript libraries that are added to a project. For most libraries, statement completion is provided automatically by the language service.

While QUnit can run in server-side or command line environments, it’s still most useful for testing JavaScript in the browser. This article explores how to write unit tests with QUnit, and how QUnit can help developing applications.

A very easy to use, cross platform, jQuery based UI toolkit, that's still small in size, has the features you need, and doesn't get in your way of doing things!

Technically, most web pages already are SPAs; it’s the complexity of a page that differentiates a web page from a web app. In my opinion, a page becomes an app when you incorporate workflows, CRUD operations, and state management around certain tasks. You’re working with a SPA when each of these tasks take place on the same page (using AJAX for client/server communication, of course).

Let’s start with this common understanding, and dive into some of the more important things that should be considered when building SPAs.

here are a number of technical considerations involved in choosing a database for a new project, but if you're looking to learn a new technology, you need the reassurance that there is traction in the field, and resources available to grow as a developer or ops professional. Here's why I think it's the right time to learn MongoDB.
