🗞 Issue 7 / 24.05.2023


📄 The State of Node.js Performance in 2023

Nearform’s Rafael Gonzaga reflects on the recent release of Node 20 and puts it through its paces against v18.16 and v16.20 with a few different benchmark suites running on a pretty typical EC2 instance. He goes into a lot of depth that’s worth checking out, but if you haven’t got time: “Node 20 is faster.” 😁

📄 Bun v0.6.0: Upping Its Node.js Compatibility Game

A ‘biggest release yet’ of the popular alternative JS runtime adds a built-in bundler and minifier, standalone executable generation, and more enhancements to its Node.js compatibility (something Bun boasts as a feature as a ‘drop-in replacement’, as opposed to Deno where it’s more of a late addition).

©️NODE.JS WEEKLY

️IN BRIEF

📜 It's not just Bun and Deno trying to offer more Node.js support, but Cloudflare Workers now has support for three more Node APIs too: node:path, the Streams API, and StringDecoder.

📜 The folks at ReversingLabs wrote about how their researchers found some 'RATs' hiding in the npm attic – specifically, the TurkoRat 'infostealer.'

📜 Fusion is a promising looking Node.js-based static site generator sent in by a Node Weekly reader. We'll cover it properly when it hits 1.0.

📄 Benchmarking a 'Compiled' Node vs Bun App

The latest release of Bun (also above) has the ability to compile apps into a single executable (something Node 20 added too, though the author uses Vercel’s pkg instead). This isn’t a particularly insightful benchmark, but does provide a data point.

📄 Server-Sent Events with Node

Server-Sent Events (SSE) enable a web server to send real-time updates to the client but without the two-way connection overhead of WebSockets.
