Web Development Principles: We Don’t Need a Framework

Posted on May 25, 2015

Over the past few weeks I’ve taken a step back from the day-to-day grind of building all things web to think about what the hell we’re trying to do here. Although I am a generally happy Lift user, there are things I would have done differently if I had built it knowing what I know now. I have decided to ask myself, "What exactly should be be building the web with?" A lot has changed since DPP wrote his Web Framework Manifesto in 2006 which formed the foundation for what became Lift. I don’t know I’m ready to embark on my own web framework creation journey, but I am ready to build up to my own manifesto.

I began to write up an entire manifesto, but it turned in to an unmanageable monolithic rant that no one will pay attention to. Instead I have decided to break this up into a series of posts on principles that I have learned to value in web development. So for those interested, this is part one of my rant which will later become condensed into a manifesto.

We Don’t Need a Framework

First off, I don’t think we need a big surrounding and opinionated web framework. What we need is a set of orthogonal libraries which you can select from a la carte and compose into solutions for the web. Back in 2006 I think building a big web application framework made a lot of sense because that’s just where we were as a community (I say this while looking back at a community I was not yet a part of). It appears to me that it was just the primary trend and big frameworks owned the majority of the mind share.

Since then I think we’ve learned that too often web applications need to go off the rails to do something particular for the problem at hand. I played a lot with Grails in late 2011/early 2012. As long as I was doing crud, this worked fine. Anything I wanted to do beyond that was met with much friction and it was never obvious how to do it. This is not to suggest it couldn’t be done, but that the happy path was a limited-access highway ill-fit for anything other than main-stream development.

Although Lift is a framework, I’ve found it to be on the lighter end of the weight spectrum. It is very easy to forgo both of its built-in persistence frameworks and use your own for instance. Yet if I’m building the webs, I’m ready to go the full distance and not have a framework at all. Instead, I want a stack of libraries that I picked out for my particular problem.

An Opinion Is a Good Start

Now about the opinionated part…​ An opinion is a good start. The ideal stack of libraries should have a low entry barrier which opinions go a long way to help. Rather than have a framework provide these opinions and marry you to them, I like the idea of having template projects. Pick from among the templates, perhaps even with a Q/A guide to help you pick the best fit.

Another reasonable alternative is to have an opinion about the defaults. I really like how sbt does this. Any directory can be an sbt project. All you need to do is run sbt in the directory and you are in your sbt project. You then specify any deviation from the defaults in your build.sbt file. So perhaps we have a library of some sort which ties the libraries all together into a set of defaults with a config file to let you deviate as needed.

Either approach would make me happy, although I would favor the former if I end up building something.

My first guiding principle for my ideal framework is that it is not a framework at all, but a set of libraries. I think I’ll call it a stack until I decide that is inappropriate. Although it isn’t a framework, there should be an easy way to get started via opinionated templates or defaults.
