Simplest Thing That Works
I remember working for a .NET development shop back in 2005. .NET 2.0 was still in its nascent phase, and the team I was on was still relatievely new to .NET. We were all trying to figure out best practices, object design, etc. But we were good developers, and knew that it’s always best to go with libraries and frameworks that are already written, ones that will simplify the task at hand. The library that was popular among the team was CSLA.
Now I should mention right up front, for full disclosure, that I’m personally not a fan of CSLA. But everyone has their own opinion, and I know many teams have used CSLA to great success. The post below is not about CSLA, but rather about finding the right tool, and the right functionality.
There’s this famous scene in Spinal Tap, a mockumentary about a fictitious rock band, where the lead guitarist, Nigel Tufnel, explains to the reporter how his amp is louder because it goes to 11. When asked why he simply didn’t make 10 louder, Nigel is befuddled and again states the amp goes to 11, which is one more than 10. 11 must be louder, right?
When we discussed using CSLA in our team, one of the arguments that was given in its favor was CSLA had built-in support for remoting, a precursor to WCF. Our project, however, not only had no need for remoting, it would never need remoting. The fact that the framework supported remoting was of no concern to our application.
However, “this one goes up to 11.” “This supports remoting. And isn’t that cool?”
Yes, it’s cool - if we need remoting. Otherwise, we’re simply adding complexity for complexity’s sake.
If you look out over the developer landscape, you’ll notice tool upon tool, framework upon framework, all offering some set of functionality, with promises to make your life as a developer easier. And most frameworks and tools will do exactly that. But, those tools may come at a cost in increased complexity.
On the web side of things, you have NPM, Grunt, Gulp, Bower, …, to help manage packages, files, workflows, etc. And you have jQuery, Bootstrap, Knockout, Angular, …, to make developing front ends that much easier. And the list goes on and on.
All of those various tools and frameworks have their place, and they can all bring additional power, and help you create applications that much faster. But they can also add unnecessary bloat. And complexity.
Before taking a dependency on a tool or framework, make sure the features it provides are what you actually need. For example, Ember.js has this amazing data store; it’s my favorite feature of that framework. But if you’re not making many Ajax calls and working with data, but rather need to simply update the front end dynamically, why choose that as your framework? Why not use jQuery? Or maybe Knockout?
As a perfect example, I am currently pecking out a sample NodeJS application. I dutifully sat down and started adding in various packages, started tweaking my Gulp file, and then stopped myself.
It’s a simple sample application.
Do I need to use LESS? Since I’m just going to be using the default Bootstrap theme, there’s no need for me to worry about pre-processors or the like. Could I use LESS? Sure, but I don’t need it to survive.
If the sample application starts to grow and become more complex, maybe I’ll revisit those decisions. But right now, I don’t need them. Why would I take a dependency on something that offers me features that I don’t need?
Instead, make 10 louder.
