We also need to talk about Source Order vs. Tab Order—they’re more different than you’d expect 👀. Source Order is the sequence of nxodes inside their parent in the DOM. Tab Order is the sequence of focusable nodes navigated using the Tab key. If a focusable element lacks tabindex, it follows a depth-first traversal of Source Order (visualized conceptually as a traversal path). Want to visualize Source Order?... - Source: dev.to / 22 days ago

That's pretty cool! Get ready to keep these up to date monthly or become obsolete quickly. One of the downsides of tools like this is that your URL needs to be available online so if there's an issue, your iteration loop is quite long. In Polypane [1] I've built social media previews that work with any local URL but also let you overwrite that URL for the social media that display those. I built (and frequently... - Source: Hacker News / 9 months ago

I had heard about Polypane before and I think I may have tried it a few years ago, but nowadays, It's a must for frontend. It helps you build out responsive, accessible apps with all kinds of goodies. Curious about it? I hung out with the creator of Polypane on a live-stream earlier this year. - Source: dev.to / about 1 year ago
But I want to say that this topic is clearly not new in 2025, I will not reveal anything supernatural here. HTMX and Alpine.js have already fully proven to everyone that this is not nonsense. I am just retelling everything, but with one interesting remark - this is the HMPL template language which is better than the previous two in some tasks. Next, I will describe why and how it will help you replace Next.js. - Source: dev.to / 14 days ago
This article assumes the reader is a developer that knows their way around Markdown, TypeScript, React.js, and [Next.js] https://nextjs.org/). Familiarity with Tailwind-css would also be useful. - Source: dev.to / 16 days ago
The popularisation of SSR among frontend developers can be largely attributed to the widespread adoption of frameworks with server-side rendering. These frameworks provide an elegant integration of SSR with modern JavaScript libraries and frameworks like React and Vue.js. Next.js, for instance, has become a de facto choice for many React developers seeking to leverage SSR's benefits without sacrificing the... - Source: dev.to / 16 days ago
My only true recommendation would be to prefer React for mobile or SSR applications, as community projects (Expo for mobile and Next.js for SSR) are more mature and easier to set up. - Source: dev.to / 26 days ago
