Hi Everyone! In the last two weeks I have been traveling in the South of France with my family - I really needed a break. I’ve quickly assembled this edition composed of a few important releases and a lot of interesting articles. As usual, let me know what you think!

Many developers ask the same question when joining the Fastify community: how do we know which modules are core and which one are ecosystem? We have listened and migrated all core modules to use the @fastify scope on npm. Read more at:

Following up the massive release of all core modules, the Fastify team shipped all the module updates, including fastify v3.29.0.
Pino v7.11.0 ships with full TypeScript support for transports. [email protected] ships a few improvements to help Damien implement file rotation for pino.
Node.js v18 also fixes a few important performance problems in using class fields. Read the article Joyee wrote at
…and the longer explanation within V8:
A big news of the last two weeks has been the OpenSSF selecting Node.js for Project Alpha - they will fund the OpenJS Foundation and in turn NearForm to help improve the security of Node.js. Read more at:

The response to this blog post is the following thread from Sebastian:
Sebastian Markbåge
Hydration in React was originally not built for SSR. It was because IE6 had a really slow DOM API but relatively fast JS strings. It was faster to concat HTML strings on the client and then "hydrate" it. This equation later changed as more refs were used and the DOM got faster.
Should you use Marko? It’s hyper-performant framework for building sites:
…and then use Solid for apps!
Jest 28 was released to support Node v18 and improving a lot of things! Note that I normally do not recommend using Jest to test your Node.js applications - however most of you use it anyway. Check it out:
Most of the time startups fails into oblivion without no explanation. It’s really good to read up Zaplib post-mortem. I find the article really interesting because it shows that JavaScript (or TypeScript) are to dominate the frontend world for a long time and will not be replaced by Wasm/Rust/AssemblyScript.
