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.

If Not React, Then What? - Infrequently Noted

Put the kettle on; it’s another epic data-driven screed from Alex. The footnotes on this would be a regular post on any other blog (and yes, even the footnotes have footnotes).

This is a spot-on description of the difference between back-end development and front-end development:

Code that runs on the server can be fully costed. Performance and availability of server-side systems are under the control of the provisioning organisation, and latency can be actively managed by developers and DevOps engineers.

Code that runs on the client, by contrast, is running on The Devil’s Computer. Nothing about the experienced latency, client resources, or even available APIs are under the developer’s control.

Client-side web development is perhaps best conceived of as influence-oriented programming. Once code has left the datacenter, all a web developer can do is send thoughts and prayers.

As a result, an unreasonably effective strategy is to send less code. In practice, this means favouring HTML and CSS over JavaScript, as they degrade gracefully and feature higher compression ratios. Declarative forms generate more functional UI per byte sent. These improvements in resilience and reductions in costs are beneficial in compounding ways over a site’s lifetime.

Oh, how I wish that every team building for the web would use this sensible approach!

Reckoning: Part 1 — The Landscape - Infrequently Noted

I want to be a part of a frontend culture that accepts and promotes our responsibilities to others, rather than wallowing in self-centred “DX” puffery. In the hierarchy of priorities, users must come first.

Alex doesn’t pull his punches in this four-part truth-telling:

1. The Landscape
2. Object Lesson
3. Caprock
4. The Way Out

The React anti-pattern of hugely bloated single-page apps has to stop. And we can stop it.

Success or failure is in your hands, literally. Others in the equation may have authority, but you have power.

Begin to use that power to make noise. Refuse to go along with plans to build YAJSD (Yet Another JavaScript Disaster). Engineering leaders look to their senior engineers for trusted guidance about what technologies to adopt. When someone inevitably proposes the React rewrite, do not be silent. Do not let the bullshit arguments and nonsense justifications pass unchallenged. Make it clear to engineering leadership that this stuff is expensive and is absolutely not “standard”.

Henry From Online | How To Make a Website

Write meaningful HTML that communicates the structure of your document before any style or additional interactivity has loaded. Write CSS carefully, reason your methodology and stick to it, and feel empowered to skip frameworks. When it comes time to write JavaScript, write not too much, make sure you know what it all does, and above all, make sure the website works without it.

The whole article is great, and really charmingly written, with some golden nuggets embedded within, like:

• You’ll find that spending more time getting HTML right reveals or even anticipates and evades accessibility issues. It’s just easier to write accessible code if it’s got semantic foundations.
• In my experience, you will almost always spend more time overriding frameworks or compromising your design to fit the opinions of a framework.
• Always style from the absolute smallest screen your content will be rendered on first, and use @media (min-width) queries to break to layouts that allow for more real estate as it becomes available.
• If your site doesn’t work without JavaScript, your site doesn’t work.
• Always progressively enhance your apps, especially when you’re fucking with something as browser-critical as page routing.
