Power of the platforms

Uncertainty is a feature, not a bug.

After decades of work on programming, we finally got a development environment with massive reach and tremendous power. Somehow, though, the web isn’t centered on a comprehensive programming environment. The web succeeded with a (severely) lowest-common denominator, specification-driven approach that let it grow with time, technology, and multiple communities, across multiple platforms.

Almost two decades ago, I was all excited about Java. Write applets once, run anywhere, with libraries to make sure it all came out the same wherever anywhere might be. Java is still a powerhouse, but it all worked out differently than I expected. Even in Java’s early years, before the Java news was filled with security bulletins, applets felt like a strange mix with their surrounding web pages. Creating an applet demanded programmers to build every detail. Even with Java’s ever-improving libraries, creating a Java applet that did much was an intense experience focused on programming.

Java wasn’t the only comprehensive way to build web apps, of course. Flash demanded programming, but its values always incorporated design, action, and well, flash, in ways that meshed well with the way people built sites. Flash kept growing and growing before its ecosystem took a fatal hit from the iPhone as HTML5 offered replacements for some of its key strengths. I mostly notice Flash these days because it asks me to update it regularly and because pages tell me when it’s crashed.

Compared to either of those rich environments, web technology is a tangled mess. The early web was functional but unstyled, with no behavior beyond navigating among pages. That? That would dominate client-side computing?

Absolutely. That barely functional but unstyled approach made it possible for many many different people to create many different tools for creating and presenting that content. The web crossed platforms rapidly, as environments rushed to add browsers; browsers started running across multiple environments; and many environments found themselves with multiple options available. It wasn’t all just browsers, either — writing code that scraped or otherwise interpreted web content wasn’t that hard.

Two decades of almost continuous adding and tinkering brought us a much more powerful web, an environment that makes it hard to remember the tiny beginning. Though web standards are as driven (and riven) by committees as anything in the programming world, the separation between the creators of the rules and the platforms on which they run gives web technologies much fruitful space for experiment. The pacing has been uneven, with the browser wars rush followed by a long fallow period and then a race forward into HTML5. As devices have evolved, web technology has found ways to include new features. The competition many of us feared we’d lost when Internet Explorer ruled the roost is back.

But yes, this makes things complicated. Programmers who work in a world where they can control the execution environment often expect the same control on the web. As much as I like “the Web Platform” sparing me syllables over HTML, CSS, JavaScript, and more, Jeremy Keith is right: treating the web as a platform with all the brittle expectations of a platform is a terrible idea.

So stop being brittle. The web bends with the wind, supporting incredibly diverse use cases across a wide variety of environments. Your code should, too.

Editor’s note: If you’re ready to scrap the rules you’ve relied on all these years and embrace uncertainty as a core tenet of design, check out The Uncertain Web, by Rob Larsen.
