👀 Useful Patterns for Building HTML Tools
In many situations, you don’t need a full-on framework to build useful tools; just HTML, JavaScript and CSS in a single file will do the job fine. Simon’s become a bit of an expert by rolling out many such tools using LLMs, and shares his process and practices here. More please!

👀 Many Devs blame Vercel for Next.js-related React security vulnerabilities.
Because making new frameworks like Next.js is relatively easy nowadays, someone with enough social influence can literally destroy Vercel's business by popularising some other framework, which, by the way, would have nearly identical problems anyway, because this was mostly the React problem itself.

🔵 Denial of Service and Source Code Exposure in React Server Components
Security researchers have found and disclosed two additional vulnerabilities in React Server Components while attempting to exploit the patches in last week’s critical vulnerability.
If you already updated for the Critical Security Vulnerability last week, you will need to update again.
If you updated to 19.0.2, 19.1.3, and 19.2.2, these are incomplete and you will need to update again.
