JavaScript is the web’s CO2. We need some of it, but too much puts the entire ecosystem at risk. Those who emit the most are furthest from suffering the consequences — until the ecosystem collapses. The web will not succeed in the markets and form-factors where computing is headed unless we get JS emissions under control.
Damn, that’s a fine opening! And the rest of this post by Alex is pretty darn great too. He’s absolutely right in calling out the fetishisation of developer experience at the expense of user needs:
The swap is executed by implying that by making things better for developers, users will eventually benefit equivalently. The unstated agreement is that developers share all of the same goals with the same intensity as end users and even managers. This is not true.
I have a feeling that this will be a very bitter pill for many developers to swallow:
If one views the web as a way to address a fixed market of existing, wealthy web users, then it’s reasonable to bias towards richness and lower production costs. If, on the other hand, our primary challenge is in growing the web along with the growth of computing overall, the ability to reasonably access content bumps up in priority. If you believe the web’s future to be at risk due to the unusability of most web experiences for most users, then discussion of developer comfort that isn’t tied to demonstrable gains for marginalized users is at best misguided.
Oh,captain, my captain!
Tools that cost the poorest users to pay wealthy developers are bunk.
“And so what we did is we started looking at, internally, all of the places where we’re using web technology — so all of our internal web UIs — and realized that they were just really unacceptably slow.”
Why were they slow? The answer: React.
“We realized that our performance, especially on low-end machines, was really terrible — and that was because we had adopted this React framework, and we had used React in probably one of the worst ways possible.”
Every problem at every company I’ve ever worked at eventually boils down to “please dear god can we just hire people who know how to write HTML and CSS.”
What Trys describes here mirrors my experience too—it really is worth occasionally taking a little time to catch the low-hanging fruit of your site’s web performance (and accessibility):
I’ve shaved nearly half a megabyte off the page size and improved the accessibility along the way. Not bad for an evening of tinkering.
