Riding New Ground (Part 1): Web Browser Application with HTML 5, CSS 3, JavaScript, Microdata, and Mopeds

It's like XML, but you can store source code in it.

This is part 1 of a tutorial, or commentary at least, related to my recent experience building the Mopedum Webshop. The software is licensed for Mopedum's use and may be generalized and put into an open-source project by the HLL Project. Aside from title technologies, Tomcat, Java, and database systems have also been used, and I will comment about listings in search engines like Google. But the real breath-taking game-changer right now is in web pages; HTML 5 and dynamic coding that uses the browser, without applets, as a real application interface. I think we should talk about that.

Part 1: The Job

The webshop was built for a small business in Nynäshamn, Sweden that features a nostalgia museum, nostalgic café, nostalgic music and other events, retro boutique, and an art hall. The grand opening of the museum, which focuses on “the golden age of mopeds 1952-1979” (and contains much more than mopeds, providing a nostalgia trip through the era) took place on May 26, 2012. Throughout the entire day, the crowds overflowed onto the front deck of the renovated old community bathhouse and sidewalk, reflecting both a strong national interest in "veteran" mopeds and quite possibly the special appearance of Swedish pop icon “Lill Babs” Barbro Svensson. (Image with The Beatles: 1963) The café was also packed throughout the evening for the after-party.

The facility also includes a workshop for stripping down mopeds and preparing parts for sale as well as a stock room and a part-time sales and shipping office. Recycling at its best!

For confused American readers, let me explain the importance of mopeds in Swedish cultural history. While you drove a car to Blueberry Hill to find your freedom, mopeds gave greater freedom of movement, allowing a range of activities, to Swedes and other Europeans during the “golden age.” No wonder then that a nostalgia museum built around this theme would be a hit or that it won a best contribution to local culture award after its first year. It's no wonder that there are active veteran moped clubs throughout the county and no wonder that this small business invested in 40 metric tons of old mopeds and parts.

With that as background, creation of a moped parts web shop became my slow-season winter project while others spent time preparing parts and entering information into an existing sales-system database. It was a completely custom project. Except for some occasional copy-pasting (come on, we all do it), everything in the web pages, XML files, and Java programs was typed character by character into a text editor. Java programs are written in SE 7 (plus javax.servlets). I am a tool builder who doesn't believe in relying much on other people's tools. I want efficient cutting-edge code. I want to fiddle with details myself and even blog about things. :)

Web shops are supported on some hosting sites and there are open-source web shop projects. At first glance, it may seem unreasonable to put a small business through a from-scratch custom software project. The first suggestion of a custom project came from the need to use data from their legacy database system, which is tied to their sales system, which is an nondetachable part of the business operation. They had been using the system for sale of food and drinks in the café, boutique items, and tickets to the museum. There were no plans to structure product data for a sophisticated drill-down such as is normally supported by manufacturers and distributors of new parts; for example: category → brand → model → subsystem → parts + alternatives and related items. For best results, perhaps even just useful results, design needed to be tailored to the details and character of the actual available data.

I decided that I wanted to build web shop technology anyway and offered a license arrangement involving minimal support when I worked, extended into improvements and support after the system went on-line. With “We Are the Champions” playing in the nostalgia café (really, it was and still regularly is), the Mopedum Webshop went live on schedule, according to plan, in April, and thanks to a bit of pre-launch marketing, veteran moped parts were being shipped to customers the very next day.

This level of success was predictable. The business plan was good and had been expertly implemented and built upon. Although it is my first web shop, it's not the first web shop ever built. I've been buying things from web shops for years and there are plenty of “best practice” tips available.

If you want to try building your own web shop from scratch over the weekend as your first experimental programming project, I'd say … naaah …. better wait on that. It's not that easy. But for a seasoned professional, it isn't a high risk software project. Especially with an adaptive business model, such projects can be within reason even for small businesses. And of course, now that I have web shop technology, I'll have a head-start on the next one (or similar project).

To this point, Internet technologies have largely been built in support of commercial activities; cat pictures and web shops. Although I plan to address triumphs and challenges in “emerging” (actually emerging to actually use now) technologies in this series, the web shop also hangs on a tried-and-true backbone of such things as AJAX calls, Servlets, and JDBC, automated email messages and Google Maps.

Not only was is possible to take things from an empty instance of Notepad++ to a running system on time, the new system has been ticking like a clock ever since the launch, restarted only occasionally to bring upgrades on-line. It's been running long enough now, that together with webmaster duty, I can see the whole experience pretty clearly in hindsight.

From that view, I'm not going to teach you how to write detailed lines of code; and you may be disappointed after having read this far that there won't be any code to copy-paste. New technologies are becoming available that can change the Internet experience dramatically. I really think we, the tool and app builders, should talk about how the emerging web technologies can effect design, and even the type of applications that should now be using web browsers.

A web shop, which is very much tied to the traditional mainstream (RESTful request-response) browser based web-apps, may be one of the best cases to start that discussion; with one foot in the old world while dropping the other foot into the new.
