✌️ The ECMAScript Records and Tuples Proposal Has Been Withdrawn
Several years in the making, the record and tuples proposal offered two new deeply immutable data structures to JavaScript, but at this week’s TC39 meeting, the consensus was to drop it.

🤟 Lexe: Package a Node App into a Single Executable
Node actually has a mechanism for creating single executable applications and there are numerous other tools to do it, but Lexe takes the approach of using Amazon’s lightweight LLRT engine to make binaries of under 10MB in size. Note, however, "Lexe is not a drop-in replacement for Node.js. It only supports a subset of Node.js APIs."

🙂 Fastify + React – 7x Faster than Next.js?
Node’s Fastify framework has a mature plugin for Vite integration (explained in detail here), including @fastify/react which just hit version 1.0 and makes it easy to create fast, featureful (though obviously less so than Next.js) React apps atop Fastify. How fast? Very, it seems.

A couple of weeks ago, something unexpected happened. While monitoring malicious uploads to the NPM ecosystem, we stumbled on a suspicious package: react-html2pdf.js (now suspended). At first glance, it looked innocuous. 𝗡𝗼 𝗹𝗶𝗳𝗲𝗰𝘆𝗰𝗹𝗲 𝗵𝗼𝗼𝗸𝘀. 𝗡𝗼 𝗼𝗯𝘃𝗶𝗼𝘂𝘀 𝗺𝗮𝗹𝘄𝗮𝗿𝗲. Just a basic function in the index.js file.
