Is JavaScript more fragile? – Baldur Bjarnason

Progressive enhancement’s core value proposition, for me, is that HTML and CSS have features that are powerful in their own right. Using HTML, CSS, and JavaScript together makes for more reliable products than just using Javascript alone in a single-page-app.

This philosophy doesn’t apply to every website out there, but it sure as hell applies to a lot of them.

KUTE.js | Javascript Animation Engine

This looks like an interesting little JavaScript library for scripting animations.

Service Worker, what are you? - Mariko Kosaka

This is a fun—and accurate—explanation of service workers.

There’s definitely something “alien” about a service worker—it’s kind of like a virus that gets installed on the user’s device. I’ve taken to describing it as “a man-in-the-middle attack on your own website” which makes sound a bit scarier than is necessary.

Hey designers, if you only know one thing about JavaScript, this is what I would recommend | CSS-Tricks

This is a really great short explanation by Chris. I think it shows that the really power of JavaScript in the browser isn’t so much the language itself, but the DOM—the glue that ties the JavaScript to the HTML.

It reminds me of the old jQuery philosophy: find something and do stuff to it.

Custom Elements: an ecosystem still being worked out - Tales of a Developer Advocate

Really, really smart thinking from Paul here, musing on the power relationship between the creators of custom elements and the users of custom elements.

“If it’s not curlable, it’s not on the web.” by Tantek Çelik

It was fun spelunking with Tantek, digging into some digital archeology in an attempt to track down a post by Ben Ward that I remembered reading years ago.

Create a MarkDown tag - JSFiddle

This is nice example of a web component that degrades gracefully—if custom elements aren’t supported, you still get the markdown content, just not converted to HTML.

The Javascript Wars • cssence.com

Some more food for thought, following on from Shaun’s post about HTML as the foundation of web development:

There is another building block for the web, one that is more important than HTML, CSS and JavaScript combined. It all starts with URLs. Those things uniquely identify some piece of information on the web.

Performance and assumptions | susan jean robertson

We all make assumptions, it’s natural and normal. But we also need to be jolted out of those assumptions on a regular basis to help us see that not everyone uses the web the way we do. I’ve talked about loving doing support for that reason, but I also love it when I’m on a slow network, it shows me how some people experience the web all the time; that’s good for me.

I’m privileged to have fast devices and fast, broadband internet, along with a lot of other privileges. Not remembering that privilege while I work and assuming that everyone is like me is, quite possibly, one of the biggest mistakes I can make.

Web fonts, boy, I don’t know – Monica Dinculescu

Monica takes a look at the options out there for loading web fonts and settles on a smart asynchronous lazy-loading approach.

Carousels Don’t Have to be Complicated - The Media Temple Blog

If you have to use a carousel, it doesn’t have to be complicated. Chris runs through some of the options out there. It turns out you can get surprisingly far with CSS alone.

ZEIT – Next.js

I haven’t made a website with React, but if and when I do, this Node.js framework looks like it aligns nicely with my priorities. It’s all about the universal JavaScript (the artist formerly known as isomorphic JavaScript).

Introducing the Web Share API  |  Web  |  Google Developers

This is an interesting API that just landed in the newest version of Chrome behind a token—it gives you programmatic access to the OS’s share functionality via a (secure) website.

Paul finishes this rundown with the interesting bit:

Future work will also level the playing field for web apps, by allowing them to register to be a “share receiver”, enabling web-to-app sharing, app-to-web sharing and web-to-web sharing.

Maybe I’ll get to see a native “huffduff this” option in my lifetime.

Rockets of India – Medium

The fascinating history of India’s space program is the jumping-off point for a comparison of differing cultural attitudes to space exploration in Anab’s transcript of her Webstock talk, published on Ev’s blog.

From astronauts to afronauts, from cosmonauts to vyomanauts, how can deep space exploration inspire us to create more democratic future visions?

Building Social: A Case Study On Progressive Enhancement – Smashing Magazine

A step-by-step walkthrough of layering on enhancements to a site. The article shows the code used, but it isn’t really the code that matters—it’s the thought and planning that went into it.

Progressive Misconceptions, From the Notebook of Aaron Gustafson

Good stuff from Aaron…

Progressive enhancement embraces the idea of experience as a continuum rather than some singular ideal.

Progressive enhancement should not be viewed as a challenge to JavaScript any more than concepts like namespacing, test driven development, or file concatenation & minification are; it’s just another way to improve your code.

Progressive enhancement’s focus on providing a baseline experience that makes no assumptions about browser features will provide a robust foundation for any project.

The Service Worker Lifecycle  |  Web  |  Google Developers

Jake goes into the details of what exactly is happening when a service worker is installed or replaced.

This is easily the most complex part of working with service workers, and I think I’m beginning to wrap my head around it, but the good news is that, for the most part, you don’t really need to know the ins and outs of this to get started (and dev tools are now making it easier to nuke from orbit if this begins to bite).

Does Progressive Enhancement Have a Place in Today’s Web? - George Brocklehurst, thoughtbot - YouTube

Spoiler: the answer is “Yes!”.

It’s a way of building web applications that’s very similar to making a sandwich.

This talk is itself a tasty sandwich of good stuff.

Thimble by Mozilla - An online code editor for learners & educators.

This is a really, really nice tool for creating HTML, CSS, and JavaScript without needing a separate text editor. And then you can publish the results to a URL.

It’s a bit like CodePen but it shows the whole HTML document, which makes it particularly useful for teaching front-end development to beginners (ideal for Codebar!).

CodePen for snippets; Thimble for pages.

Enhancing a comment form: From basic to custom error message to BackgroundSync | justmarkup

This is a truly fantastic example of progressive enhancement applied to a form.

What I love about this is that it shows how progressive enhancement isn’t a binary on/off choice: there are layers and layers of enhancements here, from simple inline validation all the way to service workers and background sync, with many options in between.

Superb!
