Trys describes exactly the situation where you really do need to use the Shadow DOM in a web component—as opposed to just sticking to HTML web components—, and that’s when the component is going to be distributed and you have no idea where:
This component needed to be incredibly portable, looking great on any third-party website, in any position, at any viewport, with any amount of content. It had to be a “hyper-responsive” component.
“And so what we did is we started looking at, internally, all of the places where we’re using web technology — so all of our internal web UIs — and realized that they were just really unacceptably slow.”
Why were they slow? The answer: React.
“We realized that our performance, especially on low-end machines, was really terrible — and that was because we had adopted this React framework, and we had used React in probably one of the worst ways possible.”
Oh, how I wish that every team building for the web would use this sensible approach!
Debating complexity is pointless because it’s a subjective metric. Every developer has a different gut feeling about simplicity, complexity and the appropriate amount of complexity for a given task. When people try to find an objective definition, they come to wildly different results. And that’s okay.
Instead, we should focus on hard metrics from a user perspective. Performance, efficiency, compatibility, accessibility and fault-tolerance can be measured, tested and evaluated, automatically and manually.
Any amount of complexity is fine as long as these goals are met.
Since the early days of the web, large corporations have seemingly always wanted more than the web platform or web standards could offer at any given moment. Whether they were aiming for cross-platform-compatibility, more advanced capabilities, or just to be the one runtime/framework/language to rule them all, there’s always been a company that believes they can “fix” it or “own” it.
Applets. ActiveX. Flash. Flex. Silverlight. Angular. React.
This is grim:
If you look at the data below on how popular websites today are actually transpiling and deploying their code to production, it turns out that most sites on the internet ship code that is transpiled to ES5, yet still doesn’t work in IE 11—meaning the transpiler and polyfill bloat is being downloaded by 100% of their users, but benefiting none of them.
Its proponents can be weird, it takes itself far too seriously, and its documentation is interminable. These are some ways that some people have described Christianity. This video is about React.js.
Perhaps the tide is finally turning against complex web frameworks.
I want to be a part of a frontend culture that accepts and promotes our responsibilities to others, rather than wallowing in self-centred “DX” puffery. In the hierarchy of priorities, users must come first.
Alex doesn’t pull his punches in this four-part truth-telling:
The React anti-pattern of hugely bloated single-page apps has to stop. And we can stop it.
Success or failure is in your hands, literally. Others in the equation may have authority, but you have power.
Begin to use that power to make noise. Refuse to go along with plans to build YAJSD (Yet Another JavaScript Disaster). Engineering leaders look to their senior engineers for trusted guidance about what technologies to adopt. When someone inevitably proposes the React rewrite, do not be silent. Do not let the bullshit arguments and nonsense justifications pass unchallenged. Make it clear to engineering leadership that this stuff is expensive and is absolutely not “standard”.
Three great examples of HTML web components:
What I hope is that you now have the same sort of epiphany that I had when reading Jeremy Keith’s post: HTML Web Components are an HTML-first feature.
Progressive enhancement is a design and development principle where we build in layers which automatically turn themselves on based on the browser’s capabilities.
The idea of progressive enhancement is that everyone gets the perfect experience for them, rather than a pre-determined “perfect” experience from a design and development team.
The paradigm shift that web development is entering hinges on the fact that while React was a key enabler of the Single-Page-App and Component era of the web, in practice it normally tends to result in extremely poor products. Built-in browser APIs are now much more capable than they were when React was first invented.
Can we please stop adding complexity to our systems just so we can do it in JavaScript? If you can do it without JavaScript, you probably should. Tools shouldn’t add complexity.
You don’t need a framework to render static content to the end user. Stop creating complex solutions to simple problems.
One dev team made the shift from React’s “overwhelming VDOM” to modern DOM APIs. They immediately saw speed and interaction improvements.
Yay! But:
…finding developers who know vanilla JavaScript and not just the frameworks was an “unexpected difficulty.”
Boo!
Also, if you have a similar story to tell about going cold turkey on React, you should share it with Richard:
If you or your company has also transitioned away from React and into a more web-native, HTML-first approach, please tag me on Mastodon or Threads. We’d love to share further case studies of these modern, dare I say post-React, approaches.
This looks interesting. On the hand, it’s yet another proprietary creation by one browser vendor (boo!), but on the other hand it’s a declarative API with no JavaScript required (yay!).
Even if this particular feature doesn’t work out, I hope that this is the start of a trend for declarative access to browser features.
There’s a big difference between the interface to a thing being one line of code, and the cost of a thing being one line of code.
A more acute rendering of this sales pitch is probaly: “It’s just one line of code to add many more lines of code.”
And as Chris puts it:
Every dependency is a potential vulnerability
Photoshop in the browser? That needs JS.
But the reality is, most of what we build is either static HTML or mostly just forms and page reloads. We can build the web that way by default, and progressively enhance a more Ajaxy experience on top of it.
The result is an app that’s faster to load, faster to run, and less prone to breaking… without much additional work for your developers.
Call it HTMLX or call it Hijax, what matters isn’t the code so much as the idea:
Front-end JavaScript fatigue is real. I’m guilty myself of over-engineering JS UI despite preferring good old server templates. I don’t even think HTMX is that good but the philosophy behind it embarrasses the modern JavaScript developer. For that I appreciate it very much.
This is a great thought exercise in progressive enhancement …that Scott then turns into a real exercise!
When I was in Amsterdam I was really impressed with the code that Rose was writing and I encouraged her to share it. Here it is: drop this script into a web page with a form to have its values automatically saved into local storage (and automatically loaded into the form if something goes wrong before the form is submitted).
