Wouhou ! I created a multithreaded logger in Node.js...
The goal ?
* free up bandwidth for CPU intensive tasks,
* have a synchronous (hence thread blocking) compressed (hence CPU intensive) trace storage,
* implement a nice console output which does not block other threads.
was a fun ride !

It’s a big responsibility when you decide to completely rewrite a component. Yet, I take this opportunity to improve all the little details that were bugging me over the last 5 years.
It will take time but it should be rewarding.

I like refactoring: this is an opportunity to rewrite with the knowledge of all the faced challenges. Yet, this feels like a huge mountain to climb.

Sometimes I feel like when I want to ask a question to the LLM, I spend so much effort to formulate it the right way that I almost get the answer by myself...

Tried to create a simple command line app with GEMINI to validate an idea... A bit disappointed (some mistakes) but got it to work. It certainly saved me a bit of time...

Using compression (& decompression stream) I was able to reduce the HUGE html report (168 MB) down to 9 MB... and it loads fine (& fast) in the browser !

So... you can actually decompress content inside a web page. Today I learned about DecompressionStream : developer.mozilla.org/en-US/docs/W...
DecompressionStream - Web APIs | MDN
The DecompressionStream interface of the Compression Streams API is an API for decompressing a stream of data.

Working on automating OpenUI5 existing tests with ui5-test-runner (since karma is no more maintained).
Some metrics on sap.ui.core tests :
- 600+ unit tests
- 17 minutes to execute (10 parallel executions)
- 29+ tests failing (need to check)
- A 172 MB HTML report (!)
Room for improvement !

Something big is coming soon to ui5-test-runner... I never thought I would be able to achieve a bridge between jest and QUnit. The reality is that both JavaScript and QUnit are powerful tools.
