Building a Frontend Framework; Reactivity and Composability With Zero Dependencies

The thinking behind the minimal JavaScript framework, Strawberry:

Even without specialized syntax, you can do a lot of what the usual frontend framework does—with similar conciseness—just by using Proxy and WebComponents.

Why We’re Breaking Up with CSS-in-JS | Brad Frost

I’ve seen the pendulum swing back and forth many times over my years building on the web. I too feel like there’s something in the air right now, and people are finally acknowledging that most single page apps are crap.

But Brad makes the interesting point that, because they were incubated when profligate client-side JavaScript was all the rage, web components may have ended up inheriting the wrong mindset:

So now the world of web components has egg on its face because the zeitgeist at the time of its design didn’t have such a strong focus on SSR/HTML-first/ progressive enhancement. Had web components been designed in the current zeitgeist, things would almost certainly be different.

A Web Component Story

I get it. React feels good and it’s sticky. But all frameworks eventually fizzle out.

Thanks to Web Components, large companies are realizing you don’t need to rebuild buttons and other UI primitives every few years. Teams don’t need to argue about frameworks anymore. You can have your cake and eat it too!

I think this may be the best long-term argument for web components:

Any org that goes all in on a single framework will eventually find themselves swimming upstream to hire talent to maintain legacy code and avoid framework rot. But you can reduce this burden (and the associated costs) by using Web Components in your design system.

Why I don’t miss React: a story about using the platform - Jack Franklin

This is a great case study of switching from a framework mindset to native browser technologies.

Though this is quite specific to Jack’s own situation, I do feel like there’s something in the air here. The native browser features are now powerful and stable enough to make the framework approach feel outdated.

And if you do want to use third-party dependencies, Jack makes a great case for choosing smaller single-responsibility helpers rather than monolithic frameworks.

Replacing lit-html would be an undertaking but much less so than replacing React: it’s used in our codebase purely for having our components (re)-render HTML. Replacing lit-html would still mean that we can keep our business logic, ultimately maintaining the value they provide to end-users. Lit-Html is one small Lego brick in our system, React (or Angular, or similar) is the entire box.

Web Components as Progressive Enhancement - Cloud Four

This is exactly the pattern of usage I’ve been advocating for with web components—instead of creating a custom element from scratch, wrap an existing HTML element and use the custom element to turbo-charge it, like Zach is doing:

By enhancing native HTML instead of replacing it, we can provide a solid baseline experience, and add progressive enhancement as the cherry on top.

Design Systems Aren’t Cheap

Just like jQuery dominated the front end yesterday, React dominates it today. There will be something new that dominates it tomorrow. Your design system team will continue doing the same work and incurring more and more costs to keep up with framework churn. And let’s not forget the cost of updating tomorrow’s legacy apps, who are consumers of your soon to be legacy design system.

Add Responsive-Friendly Enhancements to `details` with `details-utils`—zachleat.com

This is how a web component should be designed! Zach has made a custom element that wraps around an existing HTML element, turbocharging its powers. That’s the way to think about web components—as a progressive enhancement.

HTML with Superpowers - daverupert.com

A great talk from Dave on web components:

I think if you were using Web Components before 2020 you were an early adopter and you probably have some scars to show for it. But in 2021, now that all modern browsers support Web Components, I think they’re worth investigating. They have one superpower that no other JavaScript framework offers called the Shadow DOM which is both powerful but frustrating. But another superpower — the power I’m most excited about — is that you can use them standalone without any frameworks, build tools, or package managers.

The talk makes a callback to my talk Building from a few years back. I like that. It feels like a long thoughtful converstation.

Using the platform

Elise Hein documents what it was like to build a website (or web app, if you prefer) the stackless way:

  • use custom elements (for modular HTML without frameworks)
  • use the in-browser package manager (for JavaScript packages without build tools)
  • match pages with files (to avoid routing and simplify architecture)
  • stick to standards (to avoid obsolescence and framework fatigue)

Her conclusions are similar to my own: ES6 modules mean you can kiss your bundler goodbye; web components are a mixed bag—it’s frustrating that Apple are refusing to allow native elements to be extended. Interestingly, Elise feels that a CSS preprocessor is still needed for her because she wants to be able to nest selectors …but even that’s on its way now!

Perhaps we might get to the stage where it isn’t an automatic default to assume you’ll need bundling, concatenation, transpiling, preprocessing, and all those other tasks that we’ve become dependent on build tools for.

I have a special disdain for beginner JavaScript tutorials that have you run create-react-app as the first step, and this exercise has only strengthened my conviction that every beginner programmer should get to grips with HTML, CSS and vanilla JS before delving into frameworks. Features native to the web are what all frameworks share, and knowing the platform makes for a stronger foundation in the face of change.

Tabs in HTML?

I’ve been having some really interesting chats with Brian about tabs, markup, progressive enhancement and accessibility. Here’s a braindump of his current thinking which is well worth perusing.

It’s good to hear stories like this—makes me feel like the slow-burn of the theoretical benefits of web components is starting to spark and flame up.

Container Queries in Web Components | Max Böck

The point of this post is to show how nicely container queries can play with web components, but I want to also point out how nice the design of the web component is here: instead of just using an empty custom element, Max uses progressive enhancement to elevate the markup within the custom element.

I really like the idea of a shared convention for styling web components with custom properties—feels like BEM meets microformats.

Open UI and implicit parent/child relationships in HTML – Eric Bailey

I remember discussing this with Tantek years ago:

There are a few elements who need to be placed inside of another specific element in order to function properly.

If I recall, he was considering writing “HTML: The Good Parts”.

Anyway, I can relate to what Eric is saying here about web components. My take is that web components give developers a power that previous only browser makers had. That’s very liberating, but it should come with a commensurate weight of responsibility. I fear that we will see this power wielded without sufficient responsibility.

I’m very taken with Github’s tab-container element—this is exactly how I think web components should be designed!

The failed promise of Web Components – Lea Verou

A spot-on summary of where we’ve ended up with web components.

Web Components had so much potential to empower HTML to do more, and make web development more accessible to non-programmers and easier for programmers.

But then…

Somewhere along the way, the space got flooded by JS frameworks aficionados, who revel in complex APIs, overengineered build processes and dependency graphs that look like the roots of a banyan tree.

Alas, that’s true. Lea wonders how this can be fixed:

I’m not sure if this is a design issue, or a documentation issue.

I worry that is a cultural issue.

Using a custom element from the directory often needs to be preceded by a ritual of npm flugelhorn, import clownshoes, build quux, all completely unapologetically because “here is my truckload of dependencies, yeah, what”.

Interactive Elements: A Strange Game

Just today I was discussing with Trys and Cassie why developers tend to create bespoke JavaScript-driven components rather than using the elements that browsers give us for free. It all comes down to the ability to style the user interface.

Here, Brian proposes a kind of minimum viable web component that handles logic like keyboard control and accessibility, but leaves the styling practically untouched. Check out his panel-set demo of a tabbed interface.

I really, really like the way that it wraps existing content. If the web component fails for any reason, the content is still available. So the web component is a progressive enhancement:

An experimental custom element that wraps plain-old HTML (view the source) and decorates function, keyboard handling, accessibility information.

A very handy web component from Paul—this works exactly like a regular YouTube embed, but is much more performant.

Progressive Enhancement

This post was originally written in 2015, but upon re-reading it today, it still (just about) holds up, so I finally hit publish.
