One of the other arguments we hear in support of the SPA is the reduction in cost of cyber infrastructure. As if pushing that hosting burden onto the client (without their consent, for the most part, but that’s another topic) is somehow saving us on our cloud bills. But that’s ridiculous.
Sensible advice from Chris:
So what’s the best rendering method? Whatever works best for you, but perhaps a hierarchy like this makes some general sense:
- Static HTML as much as you can
- Edge functions over static HTML so you can do whatever dynamic things
- Server generated HTML what you have to after that
- Client-side render only what you absolutely have to
A good explanation of the hydration problem in tools like Gatsby.
Garrett’s observation is spot-on here:
This is a very important point:
It’s important not to try making the no-JS experience work like the full one. The interface has to be revisited. Some features might even have to be removed, or dramatically reduced in scope. That’s also okay. As long as the main features are there and things work nicely, it should be fine that the experience is not as polished.
This is a great little technique from Remy: when a service worker is being installed, you make sure that the page(s) the user is first visiting get added to a cache.
Chris broke both his arms just to avoid speaking at the JAMstack conference in London. Seems a bit extreme to me.
Anyway, to make up for not being there, he made a website of his talk. It’s good stuff, tackling the split.
It’s cool to see the tech around our job evolve to the point that we can reach our arms around the whole thing. It’s worthy of some concern when we feel like complication of web technology feels like it’s raising the barrier to entry
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.
A good analysis, but my takeaway was that the article could equally be called Why it’s tricky to measure Client-side Rendering performance. In a nutshell, just looking at metrics can be misleading.
Pre-classified metrics are a good signal for measuring performance. At the end of the day though, they may not properly reflect your site’s performance story. Profile each possibility and give it the eye test.
And it’s always worth bearing this in mind:
This article makes a good point about client-rendered pages:
Asynchronously loaded page elements shift click targets, resulting in a usability nightmare.
…but this has nothing, absolutely nothing to do with progressive web apps.
More fuel for the fire of evidence that far too many people think that progressive web apps and single page apps are one and the same.
Rachel uncovers a great phrase for dealing with older browsers:
It isn’t your fault, but it is your problem.
She points to multiple ways of using CSS Grid today while still providing a decent experience for older browsers.
Crucially, there’s one message that hasn’t changed in fifteen years:
Websites do not need to look the same in every browser.
It’s crazy that there are still designers and developers who haven’t internalised this. And before anyone starts claiming that the problem is with the clients and the bosses, Rachel has plenty of advice for talking with them too.
Your job is to learn about new things, and advise your client or your boss in the best way to achieve their business goals through your use of the available technology. You can only do that if you have learned about the new things. You can then advise them which compromises are worth making.
Phil describes the process of implementing the holy grail of web architecture (which perhaps isn’t as difficult as everyone seems to think it is):
I have been experimenting with something that seemed obvious to me for a while. A web development model which gives a pre-rendered, ready-to-consume, straight-into-the-eyeballs web page at every URL of a site. One which, once loaded, then behaves like a client-side, single page app.
Now that’s resilient web design!
I’m so happy that Ember is moving to a server-side rendering model. Not only that, but as Tom points out here, it’s crucial that the server-side rendering is the default and the client-side functionality than becomes an enhancement.
A response to a rant I linked to recently.
I couldn’t agree more. The tools have evolved and we now have frameworks and practices that allow us to render from the server and use the same code to render on the client, progressively enhancing from a solid robust base.
The problem is that I don’t see a willingness from developers to embrace this way of thinking. Instead I see it dismissed as being unrealistic or more expensive.
Still, it always takes time for behaviour to change so maybe things will only get better. I certainly hope so.
How the Web Works: A Primer for Newcomers to Web Development (or anyone, really) by Preethi Kasireddy
This is a great reminder of the fundamental nuts’n’bolts of the internet and the World Wide Web: clients, servers, URLs, DNS, HTTP, TCP/IP, packet switching, and all the other building blocks we sometimes take for granted.
This is part one of a four-part series:

- Client-Server Model & the Structure of a Web Application
- HTTP & REST

Mike writes about what it was like being a client for a change. After working with him on the Code for America project, I can personally vouch for him as a dream client:
Clearleft’s pattern deliverables are the special-special that made the final work so strong. Jon Aizlewood’s introduction to the concept convinced me to contact Clearleft. Jeremy Keith’s interest in design systems kicked off the process, and Anna Debenham’s fucking rock star delivery brought it all home.
