What Hacker News says?
They lend you optionality of when and where you want your code to run. Plus it enables you to define the server/client network boundary where you see fit and cross that boundary seamlessly. It's totally fine to say you don't understand why they have benefits, but it really irks me when people exclaim they have no value or exist just for complexity's sake. There's no system for web development that provides the devel…

HN discussionSo here's the kicker: React Server Components don't need a server. They are completely compatible with a static bundle and still provide major benefits should you choose to adopt them (dead code elimination, build-time execution). This is effectively the design of Astro Islands, natively in React Server Components. Letting you write static and client-side dynamic code in a single paradigm through componentization an…

HN discussionNuqs[0] does a very good job at parsing and managing search params. It's a complex issue that involves serialization and deserialization, as well as throttling URL updates. It's a wonderful library. I agree, though, that it would be nice to see more native framework support for this. Forms are also hard because they involve many different data-types, client-side state, (client?) and server validation, crossing the n…

HN discussionI published a more batteries-included sample RSC+MDX blog extracted out of my own personal blog[0] You can see it here: https://rsc-mdx-blog.saewitz.com It has server-rendered mdx, client components, inline footnotes, layout bleeding, server-rendered code syntax highlighting, content-collections, and opengraph image generation. It can be rendered fully static or from a server. If you choose to deploy it as static, t…

HN discussionI agree. They can only build things that have incredibly well defined surface contracts[0], where every tasteful decision has already been made, tested, and scaled. And putting out a 50% solution counts as 'enough', even though the hard work was always in the last 50% (qa, deployment, docs, bug-fixing, etc.). And they get to effectively state 'we wrote X in Y', which makes for a great blog post, but terrible softwar…

HN discussionNodejitsu is running on fumes... they have done some good for the the OSS and node.js community through their open source efforts, but that isn't enough to keep them afloat, hence this. They have continued since last year when they went into public beta to provide a mediocre service (Downtimes, way more than publicly blogged about, issues left unaddressed, spotty support service, etc.). Don't get me wrong, their sup…
