Build for the Web, Build on the Web, Build with the Web – Web Performance and Site Speed Consultant

If I was only able to give one bit of advice to any company: iterate quickly on a slow-moving platform.

Excellent advice from Harry (who first cast his pearls before the swine of LinkedIn but I talked him ‘round to posting this on his own site).

1. Opt into web platform features incrementally
2. Embrace progressive enhancement to build fast, reliable applications that adapt to your customers’ context
3. Write code that leans into the browser, not away from it

I’m not against front-end frameworks, and, believe me, I’m not naive enough to believe that the only thing a front-end framework provides is soft navigations, but if you’re going to use one, I shouldn’t be able to smell it.

Daring Fireball: One Bit of Anecdata That the Web Is Languishing Vis-à-Vis Native Mobile Apps

I have to agree with John here:

There’s absolutely no reason the mobile web experience shouldn’t be fast, reliable, well-designed, and keep you logged in. If one of the two should suck, it should be the app that sucks and the website that works well. You shouldn’t be expected to carry around a bundle of software from your utility company in your pocket. But it’s the other way around.

There’s absolutely no technical reason why it should be this way around. This is a cultural problem with “modern front-end web development”.

The State of ES5 on the Web

This is grim:

If you look at the data below on how popular websites today are actually transpiling and deploying their code to production, it turns out that most sites on the internet ship code that is transpiled to ES5, yet still doesn’t work in IE 11—meaning the transpiler and polyfill bloat is being downloaded by 100% of their users, but benefiting none of them.

Every website and web app should have a service worker | Go Make Things

Needless to say, I agree with this sentiment.

I’ve worked with a lot of browser technology over the years. Service workers are pretty mind-blowing.
