Dark-themed code snippet showing URLPattern examples on MDN: two JavaScript blocks matching "/books" and "/books/:id" with console.log outputs.
🆕 The URL Pattern API is Newly Available!
Use it to match and extract parts of URLs, no need to reinvent routing logic. Supports literals, wildcards, named groups, and even regex constraints.

I refuse to shut up about this: NYC started charging $9 to bring a car into our most transit-rich zone, the haters & trolls predicted doom, but traffic evaporated instantly and here’s Times Square tonite (even after the holiday tourists have left). For a better future, build transit & price driving!

I havent read such a banger of an essay in a very long time. This is so well-written!
Banh you.
In February, 7-year-old Dolma Naadhun was crossing the intersection of Newtown Road and 45th Street in Astoria with her mother and sister when the driver of a 2021 Ford Explorer blew through a stop sign, striking and killing Dolma. One month later, New York City Department of Transportation commissioner Ydanis Rodriguez visited the crash site with other officials, met with community members demanding a traffic signal be installed, and promised to make changes to the street - including "daylighting" the intersection using curb extensions and plastic bollards. State assemblymember Zohran Mamdani also visited the scene that day and realized that something else needed to change. "When you take a step back and think about traffic violence in New York City," he said, "you start to understand that this is a systemic issue that is incentivized by the policies that we have in place with regard to the design of our streets and what kind of vehicles we allow to be on our roads." Whether a driver runs a stop sign or a red light, statistically, certain cars - namely, bigger SUVs and trucks - are more likely to kill a 7-year-old. This is why Mamdani is co- introducing legislation for a weight-based vehicle-registration fee intended to discourage people from purchasing heavier vehicles. "The car industry is pushing the sale of heavier and larger vehicles," he says. "The state has to make it clear that these types of vehicles come with a certain kind of cost."
soar above adult shoulders. But there may be another way to disincentivize the purchases of such vehicles, says Edwards. "One other potential idea would be for someone, maybe a city's DOT, to start keeping a list of the different makes and models of vehicles that are killing pedestrians and cyclists, or kids specifically, and post that publicly," he says. "That could bring awareness to which cars are more dangerous and also potentially affect insurance rates, which would possibly convince people not to buy certain cars." There's a bit of accountability in New York's bill, which would require the State DOT to track all fatal crashes by vehicle weight. But the other encouraging aspect of the proposal is that the collected fees stay local, by county, and, after the annual dedications to highway, bridge, and transit trust funds are met, a full 75 percent of the funds raised will go toward safety improvements like bike lanes, bollards, road diets, pedestrianization of streets, and raised crosswalks. This means the neighborhoods most impacted by large vehicles are likely to see the biggest changes. And that might be the most important part of the legislation, says Mamdani. "This is an initiative to make our streets safer for our children," he says. "And we are making sure a significant portion of this funding goes toward creating the very streetscapes that we know will save their lives."
Two years ago I interviewed a 31-year-old NY state assemblymember about a 7-year-old girl killed by an SUV driver in his district. I hung up the phone, astonished that I'd talked to a legislator who so thoughtfully articulated what actually needs to change on our streets.
He'll make a great mayor

The dream of every Muslim is simply to be treated the same as any other New Yorker.
And yet, for too long, we have been told to ask for less than that, and endure hatred and bigotry in the shadows.
No more.

Built-in HTTP proxies are now on v22 😇
(Going to update the version mentions in a WIP guide on using Node.js in enterprise network environments)
Yeah, caching strategies really should be customized for each use case, which unfortunately made it tough to provide one-size-fits-all guidance (back when that was my job).
I did build SWTL in the meantime though, which (my blog is also built with SWTL: passle.dev) does exactly what OP describes and runs both on the server and in a service worker
github.com/thepassle/swtl
FWIW, about half the articles I've written at jeffy.info are about how to think about caching for this use case 😀
In fact, I'd really urge someone to investigate this and pick it up, MAINLY because it *is* a really fun problem space to work on, where not much investigation/development by major (meta) frameworks is happening (as far as I'm aware!)
I’ve been out of this space for a while now, but I know @passle.dev put some effort into it with @astro.build. See github.com/withastro/ro..., for instance.
(Don’t know where things landed, though.)
Lit is joining @openjsf.org! 🎉

Some personal news: I'm starting a job tomorrow Bloomberg Engineering.
It'll be exciting to work someplace where JavaScript/TypeScript are key to the business. And more importantly, I'll be joining a fantastic group of people.
