Thoughts on React’s Forthcoming useEvent Hook — Last week, Dan Abramov posted an RFC for a new fundamental React hook or defining an event handler that ‘sees’ fresh props/state but has a stable function identity. James Brightman also thinks about it and thinks it’ll eventually “change the way you write modern React.”

▶  Data Visualization with D3: A 19 Hour(!) Course — I hope you’ve got some spare time for this. This is basically a mashup of D3 data visualization tutorial livestreams made by a popular datavis YouTuber. There’s a lot jammed in here and I love how easy it is to see everything as he uses a huge font size 🙂

Note: freeCodeCamp seems to be posting a lot of long ‘course’ style screencasts recently if you’re interested. Topics include React Router 6, neural networks in JS, React, and Firebase.

Meta Transferring Jest Project to the OpenJS Foundation — Meta, née Facebook, created the now popular Jest JavaScript testing framework over 10 years ago and while it’s going to continue using it internally, they now consider it ‘feature complete’ and so think it may thrive better being managed in the broader community.

IN BRIEF:

Serverpless platform AWS Lambda now has an official Node.js 16 (LTS) runtime. As does Vercel.

📅 NodeConf EU is taking place this October 3-5 in Ireland. There’s a call for speakers open until July 6 if you want to speak.

An enhanced 2FA experience is on its way to your npm account soon. Why? Security and shenanigans like this.

Cloudflare, Vercel, Shopify and contributors to both Node and Deno have established a new community group focused on the interoperability of standard Web APIs in non-browser JS environments. It’s called WinterCG for short and The New Stack has more of a writeup here.

🎂 Talking of Deno, it’s 4 years old today.

TypeScript 4.7 Release Candidate is now available – we’ll focus on it more when the final release drops.

RELEASES:

Wild Wild Path 3.0 – Dig into objects with paths and queries.
GraphQL Yoga 2.0 – Complete GraphQL server functionality.
Hexo 6.2.0 – Node.js blog framework.
graphql-schema-linter 3.0 – Validate GraphQL schema definitions.
