The React is “just” JavaScript Myth - daverupert.com

In my experience, there’s no casual mode within React. You need to be all-in, keeping up with the ecosystem, or else your knowledge evaporates.

I think Dave is right. At this point, it’s possible to be a React developer exclusively.

React is an ecosystem. I feel like it’s a disservice to anyone trying to learn to diminish all that React entails. React shows up on the scene with Babel, Webpack, and JSX (which each have their own learning curve) then quickly branches out into technologies like Redux, React-Router, Immutable.js, Axios, Jest, Next.js, Create-React-App, GraphQL, and whatever weird plugin you need for your app.

And, as Jake points out, you either need to go all in or not at all—you can’t really incrementally add Reactness to an existing project.

CSS Is So Overpowered It Can Deanonymize Facebook Users

First of all, don’t panic—this browser vulnerability has been fixed, so the headline is completely out of proportion to the reality. But my goodness, this was a clever technique!

The technique relies on luring users to a malicious site where the attacker embeds iframes to other sites. In their example, the two embedded iframes for one of Facebook’s social widgets, but other sites are also susceptible to this issue.

The attack consists of overlaying a huge stack of DIV layers with different blend modes on top of the iframe. These layers are all 1x1 pixel-sized, meaning they cover just one pixel of the iframe.

Habalov and Weißer say that depending on the time needed to render the entire stack of DIVs, an attacker can determine the color of that pixel shown on the user’s screen.

The researchers say that by gradually moving this DIV “scan” stack across the iframe, “it is possible to determine the iframe’s content.”

The Cult of the Complex · An A List Apart Article

I know that Jeffrey and I sound like old men yelling at kids to get off the lawn when we bemoan the fetishisation of complex tools and build processes, but Jeffrey gets to the heart of it here: it’s about appropriateness.

As a designer who used to love creating web experiences in code, I am baffled and numbed by the growing preference for complexity over simplicity. Complexity is good for convincing people they could not possibly do your job. Simplicity is good for everything else.

And not to sound like a broken record, but once again I’m reminded of the rule of least power.

Priority Guides: A Content-First Alternative to Wireframes · An A List Apart Article

It really, really bothers me that wireframes have evolved from being a prioritisation tool into a layout tool (disempowering UI designers in the process), so I’m happy to see an alternative like this—somewhat like Dan Brown’s Page Description Diagrams.

A Framework Author’s Case Against Frameworks - YouTube

A terrific talk by Adrian Holovaty. I really hope front-end developers talk its message to heart.

A Framework Author's Case Against Frameworks

Complexity | CSS-Tricks

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.

Seva Zaikov - Single Page Application Is Not a Silver Bullet

Harsh (but fair) assessment of the performance costs of doing everything on the client side.

Stimulus 1.0: A modest JavaScript framework for the HTML you already have

All our applications have server-side rendered HTML at their core, then add sprinkles of JavaScript to make them sparkle.

Yup!—I’m definitely liking the sound of this Stimulus JavaScript framework.

It’s designed to read as a progressive enhancement when you look at the HTML it’s addressing.

React, Redux and JavaScript Architecture

I still haven’t used React (I know, I know) but this looks like a nice explanation of React and Redux.

The Origin of Stimulus

I really like the look of this markup-driven JavaScript library from the same people who brought us the pjax library Turbolinks.

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).

All That Glisters ◆ 24 ways

I thought this post from Drew was a great way to wrap up another excellent crop from 24 Ways.

There are so many new tools, frameworks, techniques, styles and libraries to learn. You know what? You don’t have to use them.

Eric’s Archived Thoughts: Generating Wireframe Boxes with CSS and HTML5

Eric uses some super-clever CSS to “wireframe up” a web page.

I wonder if this could be turned into a little bookmarklet?

Airplanes and Ashtrays – CSS Wizardry

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.

Netflix functions without client-side React, and it’s a good thing - JakeArchibald.com

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.

Can You Afford It?: Real-world Web Performance Budgets – Infrequently Noted

Alex looks at the mindset and approaches you need to adopt to make a performant site. There’s some great advice in here for setting performance budgets for JavaScript.

JavaScript is the single most expensive part of any page in ways that are a function of both network capacity and device speed. For developers and decision makers with fast phones on fast networks this is a double-whammy of hidden costs.

CloseBrace | A Brief, Incomplete History of JavaScript

Another deep dive into web history, this time on JavaScript. The timeline of JS on the web is retroactively broken down into four eras:

  • the early era: ~1996 – 2004,
  • the jQuery era: ~2004 – 2010,
  • the Single Page App era: ~2010 - 2014, and
  • the modern era: ~2014 - present.

Nice to see “vanilla” JavaScript making a resurgence in that last one.

It’s 2017, the JavaScript ecosystem is both thriving and confusing as all hell. No one seems to be quite sure where it’s headed, only that it’s going to continue to grow and change. The web’s not going anywhere, which means JS isn’t going anywhere, and I’m excited to see what future eras bring us.

Compilers are the New Frameworks - tomdale.net

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.

The Law of Least Power and Defunct StackOverflow Answers - Web Directions

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.

HN PWA - Hacker News readers as Progressive Web Apps

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..

Four of them render absolutely no content without JavaScript.

In the Hall of Shame we have React, Preact, Angular, and Polymer.

In the Hall of Fame, we have the ones doing it right: React, Vue, and Viper.

That’s right: React appears in both. See, it’s not about the tools; it’s about how you use ‘em.

Are we making the web too complicated? | Seldo.Com Blog

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:

Are there some people using a huge pile of JavaScript and a monstrous build chain to throw together a single-pager web site with one box that collects an email address? For sure. And that’s silly and unnecessary. But so what? The misuse of technology does not invalidate 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.
