Limiting JavaScript? - TimKadlec.com

Following on from that proposal for a browser feature that I linked to yesterday, Tim thinks through all the permutations and possibilities of user agents allowing users to throttle resources:

If a limit does get enforced (it’s important to remember this is still a big if right now), as long as it’s handled with care I can see it being an excellent thing for the web that prioritizes users, while still giving developers the ability to take control of the situation themselves.

Coming to a browser near you - faster than ever before!

A great long-term perspective from Rachel on the pace of change in standards getting shipped in browsers:

The pace that things are shipping, and at which bugs are fixed is like nothing we have seen before. I know from sitting around a table with representatives from each browser vendor at the CSS Working Group how important interop is. No-one wants features to be implemented differently in browsers. This is what we were asking for with WaSP, and despite the new complexity of the platform, browsers rendering standard features in different ways is becoming increasingly rare. Bugs happen, sometimes in the browser and sometimes in the spec, but there is a commitment to avoid these and to create a stable platform we can all rely on. It is exciting to be part of it.

Introducing ‘My Browser’ - Andy Bell - Front-End Developer

Andy describes the technical approach he took building his handy reporting tool, My Browser:

Although the site is built with bleeding edge technology such as web components, it’s built with a progressive-first approach. This means that in order to get the best experience, you need to be on a modern browser, but to do the most basic function—reporting data, you can still do it by pressing a “generate report” button, which is the default state.

Not only is this a liberating way to work, it really pays off in performance:

We’re given so much for free to make a progressively enhanced website or web app. We’ve got feature detection and @supports in CSS which means that “My Browser” ships with no polyfills, fallbacks or hacks like Autoprefixer. The app degrades gracefully instead.

This has been a very refreshing way to work that I’ve enjoyed a lot. The fact that the whole thing comes in around 25kb tells you how effective progressive enhancement can be for performance too.

Best Practices With CSS Grid Layout — Smashing Magazine

A great set of answers from Rachel to frequently asked questions about CSS grid. She addresses the evergreen question of when to use flexbox and when to use grid:

I tend to use Flexbox for components where I want the natural size of items to strongly control their layout, essentially pushing the other items around.

A sign that perhaps Flexbox isn’t the layout method I should choose is when I start adding percentage widths to flex items and setting flex-grow to 0. The reason to add percentage widths to flex items is often because I’m trying to line them up in two dimensions (lining things up in two dimensions is exactly what Grid is for).

Cascading Web Design with Feature Queries ◆ 24 ways

24 Ways is back! Yay! This year’s edition kicks off with a great article by Hui Jing on using @supports:

Chances are, the latest features will not ship across all browsers at the same time. But you know what? That’s perfectly fine. If we accept this as a feature of the web, instead of a bug, we’ve just opened up a lot more web design possibilities.

A Progressive Roadmap for your Progressive Web App - Cloud Four

Jason lists the stages of gradually turning the Cloud Four site into a progressive web app:

And you can just keep incrementally adding and tweaking:

You don’t have to wait to bundle up a binary, submit it to an app store, and wait for approval before your customers benefit.

Flash is in the pan

Yeah, that’s right: The Man In Blue is back!

Resilient Web and Tools — David Larlet

David picks up on one of the closing themes of Resilient Web Design—how we choose our tools. This has been on my mind a lot; it’s what I’ll be talking about at conferences this year.

That’s part of my job to ease processes and reduce frictions. That’s part of my job to take into account from the early beginning of a product its lasting qualities.

There’s a very good point here about when and how we decide to remove the things we’ve added to our projects:

We spend our time adding features without considering at the same pace the removal of useless ones. And still the true resilience (or is it perfection Antoine?) is when there is nothing more to take away. What are you removing on Monday to make our Web more resilient?

The (Not So) Secret Powers Of The Mobile Browser – Smashing Magazine

A run-down of all the functionality that you get in browsers these days. One small quibble with the title: most of the features and APIs described here aren’t limited to mobile browsers. Still, this is a great reminder that you probably don’t need to create a native app to get the most out of a mobile device.

Web Platform Feature Availability

Here’s a handy graph from Paul:

Powered by data from caniuse.com and StatCounter, this page indicates the percentage of users who have a browser that natively supports various web platform features.

The Lumpy Web - Tales of a Developer Advocate

Paul argues that the biggest problems for interoperability on the web don’t come from support (or lack of support) for entire features, but from the frustrating inconsistencies when features land in different browsers at different times with different implementations:

  • Platform inconsistencies hurt us more than big feature differences, we should start to try and prioritize aligning the platform
  • We need better tools to help us understand what the inconsistencies are and guidance on how to manage them
  • Developers should raise more issues to keep browser vendors accountable when there are differences

State of the gap

Remy looks at the closing gap between native and web. Things are looking pretty damn good for the web, with certain caveats:

The web is the long game. It will always make progress. Free access to both consumers and producers is a core principle. Security is also a core principle, and sometimes at the costs of ease to the developer (but if it were easy it wouldn’t be fun, right?).

That’s why there’ll always be some other technology that’s ahead of the web in terms of features, but those features give the web something to aim for:

Flash was the plugin that was ahead of the web for a long time, it was the only way to play video for heavens sake!

Whereas before we needed polyfills like PhoneGap (whose very reason for existing is to make itself obsolete), now with progressive web apps, we’re proving the philosophy behind PhoneGap:

If the web doesn’t do something today it’s not because it can’t, or won’t, but rather it is because we haven’t gotten around to implementing that capability yet.

Feature.js

A lightweight alternative to Modernizr. It doesn’t add classes to your markup so it’s up to what you do with the results of any test.

It’s perfect for cutting the mustard on a case-by-case basis.

WTF Opera Mini?!

The proxy browser Opera Mini is one of the most popular mobile browsers in the world, and rightly so. Ire Aderinokun has put together a handy collection—based on caniuse.com data—of all the features that are unavailable or only partially available in that browser. The point here is not to avoid using these features, but to make sure you’ve got a solid fallback in place:

This isn’t about bashing the problem, but figuring out the solution.
