π A Massive Bug at the Heart of the npm Ecosystem
βThis is a doozy,β says the author, who used to work on the npm CLI team. We donβt want to spoil his story too much, but in short, package manifests and actual package contents donβt necessarily match up and this can be manipulated by bad actors and even trip up auditing tools.

π¬ The Cost of JavaScript in 2023
Esteemed Googler and Web performance expert Addy Osmani always brings a full, holistic view of problems and solutions to his talks, and this is no exception. He talks about the various ways JS apps are delivered and rendered, the constraints of the hardware involved, and techniques you can use to keep things running smoothly.
ADDY OSMANI
π‘ I know many readers dislike videos, but no word of a lie, this is a mini masterclass in numerous modern JS and webperf topics and worth saving for later.

π An Introduction to Parser Combinators
Parsing is rarely exciting, but Varun has done a fantastic job of making an engaging tutorial for a dry, yet extremely useful, topic. This is the bare basics, but I hope we can encourage him to finish the series :-)

π RegExp's v Flag with Set Notation and Properties of Strings
The capability of regexes in Node has been turned up a few notches, especially in the support for, and manipulation of, Unicode character sets (for example, you can now do things like 'match all Greek symbols except Ο'). The post is from 2022 but weβve been sitting on it as itβs taken till now for it to be supported.
DAVIS, SCHERER. AND BYNENS
π Setting Expectations for the Node.js Test Runner
An update on Nodeβs new test runner (stable since Node 20.0) from a TSC and core team member. He explains why an official test runner was introduced and how it tries to strike a balance between being powerful and minimal.

πDeno: An interesting take on Nodeβs default module system, covering its history, its shortcomings, and the trickiness of managing both CommonJS and ES modules at once. Unsurprisingly, Andy wants us aboard the ESM train ASAP and to leave CommonJS at the station.
π TypeScript 5.2 is now in beta.
π There's a new release of alternative JS runtime, Bun: Bun 0.6.12. Guess what? Yes, more Node.js compatibility improvements!
π A walkthrough of ways to run 'cron' style scheduled jobs in Node that ultimately promotes the author's own company, but is a reasonable roundup nonetheless.
π Liran Tal explains why to avoid Fastify's reply.raw and reply.hijack and shares an alternative approach.
