A terrific talk by Adrian Holovaty. I really hope front-end developers talk its message to heart.
We talk about complexity, but it’s all opt-in. A wonderfully useful (and simple) website of a decade ago remains wonderfully useful and simple. Fortunately for all involved, the web, thus far, has taken compatibility quite seriously. Old websites don’t just break.
Harsh (but fair) assessment of the performance costs of doing everything on the client side.
It’s designed to read as a progressive enhancement when you look at the HTML it’s addressing.
I still haven’t used React (I know, I know) but this looks like a nice explanation of React and Redux.
The philosophy behind these tools matches my own philosophy (which I think is one of the most important factors in choosing a tool that works for you, not against you).
Eric uses some super-clever CSS to “wireframe up” a web page.
I wonder if this could be turned into a little bookmarklet?
Whenever you plan or design a system, you need to build in your own ashtrays—a codified way of dealing with the inevitability of somebody doing the wrong thing. Think of what your ideal scenario is—how do you want people to use whatever you’re building—and then try to identify any aspects of it which may be overly opinionated, prescriptive, or restrictive. Then try to preempt how people might try to avoid or circumvent these rules, and work back from there until you can design a safe middle-ground into your framework that can accept these deviations in the safest, least destructive way possible.
A great bucketload of common sense from Jake:
Rather than copying bad examples from the history of native apps, where everything is delivered in one big lump, we should be doing a little with a little, then getting a little more and doing a little more, repeating until complete. Think about the things users are going to do when they first arrive, and deliver that. Especially consider those most-likely to arrive with empty caches.
And here’s a good way of thinking about that:
I’m a fan of progressive enhancement as it puts you in this mindset. Continually do as much as you can with what you’ve got.
All too often, saying “use the right tool for the job” is interpreted as “don’t use that tool!” but as Jake reminds us, the sign of a really good tool is its ability to adapt instead of demanding rigid usage:
Netflix uses React on the client and server, but they identified that the client-side portion wasn’t needed for the first interaction, so they leaned on what the browser can already do, and deferred client-side React. The story isn’t that they’re abandoning React, it’s that they’re able to defer it on the client until it’s was needed. React folks should be championing this as a feature.
- the early era: ~1996 – 2004,
- the jQuery era: ~2004 – 2010,
- the Single Page App era: ~2010 - 2014, and
- the modern era: ~2014 - present.
If you’re interested in predicting the future of the web, just look at what high-performance native systems look like, then figure out how we can apply those ideas in the browser.
I like that Tom encourages learning from native, but not at the expense of the web (hint, hint, Google devrels encouraging slavish imitation of native apps in progressive web apps with no regard for URLs).
Our job now is figuring out how to adapt the ideas of high-performance native code while preserving what makes the web great: URLs, instant loading, and a security model that allows us to forget that we run thousands and thousands of untrusted scripts every day.
I love John’s long-zoom look at web development. Step back far enough and you can start to see the cycles repeating.
Underneath all of these patterns and practices and frameworks and libraries are core technologies. And underlying principles.
These are foundations – technological, and of practice – that we ignore, overlook, or flaunt at our peril.
Of all the sites to pick to demo progressive web apps, we get the cesspit that is Hacker News …I guess it is possible to polish a turd.
Anyway, here are some examples of using frameworks to create alternative Hacker News readers. So the challenge here is to display some text to read..
That’s right: React appears in both. See, it’s not about the tools; it’s about how you use ‘em.
Laurie Voss on the trade-off between new powerful web dev tools, and the messiness that abusing those tools can bring:
Is modern web development fearsomely, intimidatingly complicated? Yes, and that’s a problem. Will we make it simpler? Definitely, but probably not as soon as you’d like. Is all this new complexity worthwhile? Absolutely.
I agree that there’s bound to be inappropriate use of technologies, but I don’t agree that we should just accept it:
I think we can raise our standards. Inappropriate use of technology might have been forgivable ten years ago, but if we want web development to be taken seriously as a discipline, I think we should endeavour to use our tools and technologies appropriately.
But we can all agree that the web is a wonderful thing:
Nobody but nobody loves the web more than I do. It’s my baby. And like a child, it’s frustrating to watch it struggle and make mistakes. But it’s amazing to watch it grow up.
Interesting ideas around front-end frameworks:
The common view is that frameworks make it easier to manage the complexity of your code: the framework abstracts away all the fussy implementation details with techniques like virtual DOM diffing. But that’s not really true. At best, frameworks move the complexity around, away from code that you had to write and into code you didn’t.
Instead, the reason that ideas like React are so wildly and deservedly successful is that they make it easier to manage the complexity of your concepts. Frameworks are primarily a tool for structuring your thoughts, not your code.
A really inspiring post by Jen outlining all the benefits of the new CSS layout features …and the problems with thinking framework-first.
I know a lot of people will think the “best” way to use CSS Grid will be to download the new version of Bootstrap (version 5! now with Grid!), or to use any one of a number of CSS Grid layout frameworks that people are inevitably going to make later this year (despite Rachel Andrew and I begging everyone not to). But I don’t. The more I use CSS Grid, the more convinced I am that there is no benefit to be had by adding a layer of abstraction over it. CSS Grid is the layout framework. Baked right into the browser.
Oh, how I wished everyone approached building for the web the way that Rachel does. Smart, sensible, pragmatic, and exciting!
Gall’s Fundamental Theorem of Systems is that new systems mean new problems. I think the same can safely be said of code—more code, more problems. Do it without a new system if you can
A cautionary tale of the risks involved with embracing new frameworks.
But when you introduce a new system, you introduce new variables, new failure points, and new problems.
…almost anything is easier to get into than out of.
