Node.js performansı nasıl optimize edilir? Bu güzel türkçe sunum için teşekkürler @mertcanaltin.bsky.social

Yesterday, I joined GDG Izmir and gave a talk on optimization in the Node.js core.

Thank you to everyone who attended!

I’m joined DevFest in Azerbaijan🇦🇿
İ talked about Node.js core & OpenSource

Removed the cost of serializing bindings in each log for the child logger.
Skipped unnecessary serializer checks.
Used direct string concatenation instead of object merging.
Sped up type checking.

Hey! Have some news!

A new high-performance logger was developed based on Pino's pattern principles.

simple: 6.06M vs 3.48M ops/s (+74% faster)
child: 5.76M vs 4.41M ops/s (+31% faster)
disabled: 174M vs 146M ops/s (+19% faster)
fields: 2.13M vs 1.36M ops/s (+56% faster)

Add tracing channels by jsumners-nr · Pull Request #2281 · pinojs/pino This PR adds a tracing channel for the asJson function. APM tools can utilize this channel for their tracing needs. At New Relic, this is the only channel we need. Other vendors may like a bit more...

Pino recently added diagnostics channel support which I guess everyone would want from node:logger too:

Thanks for sharing! I will inspect and try add node:logger

Hello everyone, I have some good news! The node:logger I was try development in last time now appears to be faster than Pino in three areas

Simple logging: **54% faster**
Disabled levels: **33% faster**

Slide saying if JavaScript has Spotify wrapped

If JavaScript was music @rginn206.bsky.social at @jsconf.bsky.social

Don’t worry, this is going to involve dropping lots of no-longer-needed APIs :-D

Unfortunately, my visa was denied. I hope I can get a visa next time.

Other than the trusted publishing stuff (which is absolutely not ready for use yet, I will be outlining why in my JS Conf talk) this is a great write up of the recent goings on.

⚡️ All set up for #JSConf !

Stop by to talk with the @vlt.sh team if you’re around!

JS Conf tomorrow!
