HTML Over The Wire | Hotwire

This is great! The folks at Basecamp are releasing the front-end frameworks they use to build Hey. There’s Turbo—the successor to Turbolinks:

It offers a simpler alternative to the prevailing client-side frameworks which put all the logic in the front-end and confine the server side of your app to being little more than a JSON API.

With Turbo, you let the server deliver HTML directly, which means all the logic for checking permissions, interacting directly with your domain model, and everything else that goes into programming an application can happen more or less exclusively within your favorite programming language. You’re no longer mirroring logic on both sides of a JSON divide. All the logic lives on the server, and the browser deals just with the final HTML.

Yes, this is basically Hijax (which is itself simply a name for progressive enhancement applied to Ajax) and I’m totally fine with that. I don’t care what it’s called when the end result is faster, more resilient websites.

Compare and contrast the simplicity of the Hotwire/Turbo approach to the knots that React is tying itself up in to try to get the same performance benefits.

Official Google Webmaster Central Blog: Timing for bringing page experience to Google Search

Good news: as of May 2021, page speed (or core web vitals, if you must) will be a ranking factor in Google Search.

Even better news: at the same time, Google AMP will lose its unfairly privileged position in the top stories carousel. Hopefully this marks the beginning of the end for Google’s failed experiment in forcing publishers to use their tech.

Kokorobot — leanerweb

The problem is that most websites will adapt to the ever faster connections, which makes them gradually inaccessible for people with slower connections. Today, most websites are impossible to download with a dial-up connection, because they have become too corpulent.

This speaks to me:

Everything we do to make it harder to create a website or edit a web page, and harder to learn to code by viewing source, promotes that consumerist vision of the web.

Pretending that one needs a team of professionals to put simple articles online will become a self-fulfilling prophecy. Overcomplicating the web means lifting up the ladder that used to make it possible for people to teach themselves and surprise everyone with unexpected new ideas.

There’s a list of links at the end of this piece to help you reach this goal:

It is vital that the web stay participatory. That means not just making sites small enough so the whole world can visit them, but small enough so that people can learn to build their own, by example. Bloat makes the web inaccessible.

Excellent research by Jeremy Wagner comparing the performance impact of React, Preact, and vanilla JavaScript. The results are simultaneously shocking and entirely unsurprising.

The Need for Speed, 23 Years Later

If you’re in a group of people being chased by a bear, you only need to be faster than the slowest person in the group. But that’s not how websites work: being faster than at least one other website, or even faster than the ‘average’ website, is not a great achievement when the average website speed is frustratingly slow.

Official Google Webmaster Central Blog: Evaluating page experience for a better web

This is excellent news for sites that were strong-armed into creating AMP pages just to get into the Top Stories carousel:

As part of this update, we’ll also incorporate the page experience metrics into our ranking criteria for the Top Stories feature in Search on mobile, and remove the AMP requirement from Top Stories eligibility.

This update doesn’t arrive until next year, but the message is clear: fast websites will be rewarded in search. I’ll be glad to see an end to AMP’s blackmail tactics.

Is it time for a Web Performance rebrand? – Simon Hearne

I think Simon is onto something here. While the word “performance” means something amongst devs, it’s too vague to be useful when communicating with other disciplines. I like the idea of using the more descriptive “page speed” or “site speed” in those situations.

Web Performance and Web Performance Optimization are still valid and descriptive terms for our industry, but we might benefit from a change to our language when working with others. The language we use could be critical to the success of making the web a faster and more accessible place.

Visitors, Developers, or Machines

Garrett’s observation is spot-on here:

I’ve been trying to understand the appeal of these frameworks by giving them an objective chance. I’ve expanded my knowledge of JavaScript and tried to give them the benefit of the doubt. They do have their places, but the only explanation I can come up with is that developers are taking a similar approach as Ruby and focusing on developer convenience and productivity. Only, instead of Ruby’s performance being tied to the CPU level, JavaScript frameworks push the performance burden to the client.

In both cases, the tradeoff happens in the name of developer happiness and productivity, but the strategies have entirely different consequences. With Ruby, the CPU is still (mostly) the responsibility of the development team, and it can be upgraded. With JavaScript, the page weight becomes an externality pushed onto visitors.

Why 543 KB keep me up at night - Manuel Matuzović

How and when did I get to the point where I would consider a page weight of 4 MB on a large page and 500 KB on a small page normal?

This isn’t just a well-earned rant from Manuel. I mean, it *is that, but it’s also packed with practical performance advice.

Reflections on software performance - Made of Bugs

I’ve really come to appreciate that performance isn’t just some property of a tool independent from its functionality or its feature set. Performance — in particular, being notably fast — is a feature in and of its own right, which fundamentally alters how a tool is used and perceived.

This is a fascinating look into how performance has knock-on effects beyond the obvious:

It’s probably fairly intuitive that users prefer faster software, and will have a better experience performing a given task if the tools are faster rather than slower.

What is perhaps less apparent is that having faster tools changes how users use a tool or perform a task.

This observation is particularly salient for web developers:

We have become accustomed to casually giving up factors of two or ten or more with our choices of tools and libraries, without asking if the benefits are worth it.

Web bloat

Pages are often designed so that they’re hard or impossible to read if some dependency fails to load. On a slow connection, it’s quite common for at least one depedency to fail.

Fire up Reader Mode and read this excellent article informed by data from using a typically slow connection in rural USA today. Two findings are:

  1. A large fraction of the web is unusable on a bad connection. Even on a good (0% packetloss, no ping spike) dialup connection, some sites won’t load.
  2. Some sites will use a lot of data!

Innovation Can’t Keep the Web Fast | CSS-Tricks

I’ve come to accept that our current approach to remedy poor performance largely consists of engineering techniques that stem from the ill effects of our business, product management, and engineering practices. We’re good at applying tourniquets, but not so good at sewing up deep wounds.

It’s becoming increasingly clear that web performance isn’t solely an engineering problem, but a problem of people.

Software disenchantment @ tonsky.me

I want to deliver working, stable things. To do that, we need to understand what we are building, in and out, and that’s impossible to do in bloated, over-engineered systems.

This pairs nicely with Craig’s post on fast software.

Everyone is busy building stuff for right now, today, rarely for tomorrow. But it would be nice to also have stuff that lasts a little longer than that.

I just got a new laptop and I decided to go with fresh installs rather than a migration. This really resonates:

It just seems that nobody is interested in building quality, fast, efficient, lasting, foundational stuff anymore. Even when efficient solutions have been known for ages, we still struggle with the same problems: package management, build systems, compilers, language design, IDEs.

Smaller HTML Payloads with Service Workers — Philip Walton

This is a great progressive enhancement for performance that uses a service worker to combine reusable bits of a page with fresh content. The numbers are very convincing!

Alas, the code is using the Workbox library, but figuring out the vanilla code to write shouldn’t be too tricky seeing as Philip talks through his logic step by step.

Six Web Performance Technologies to Watch in 2020 – Simon Hearne

The inexorable rise of frameworks such as Angular, React, Vue and their many cousins has been led by an assumption that managing state in the browser is quicker than a request to a server. This assumption, I can only assume, is made by developers who have flagship mobile devices or primarily work on desktop devices.
