One of the biggest #RxJS problems I see constantly is a misuse of switchMap. Canceling sounds nice can cause data loss. If you are not sure if switchMap is the right operator feel free to check out my blog post about it!

This is probably going to be my last big thing before paternity leave, but I kinda felt like I owed that to @danielcroe and @TheAlexLichter after they told me that WebStorm does not have a project template for Nuxt. My code needs some serious review, but it should land sooner rather than later!

We are looking for ways to improve the wording on the website around this. We are not using any code to train AI or something like that. We are much more interested in what kind of IDE features you are using, how you are using them, and what 3rd party dependencies you have installed in your project. This way we have more sophisticated data to improve the product itself. Hope this makes sense (This is somewhere described in the terms of service, but no one reads that anyway :D )

I'm thinking about making a hangout session about a short introduction about the new #RxJS docs. It should just cover the basics to make everyone able to start contributing easily. Maybe with a QA part too. Is there anyone interested in something like this?

Due to many recent discussions about wrapping web apis in #rxjs observables, I started to work on this new OSS project: github.com/JWO719/rxjs-web
It's heavily WIPish!

If you are working with @WebStormIDE and you are sharing your screen or you are giving a presentation here are 2 tipps:
1. IDE Zoom is your best friend. It is very easy to change to go right back to coding after your meeting and it enlarges all elements in the IDE, not just the font.
2. Use presentation assistant, before 2023.3 it is a seperate plugin you need to install. With 2023.3 it is bundled right in the IDE and it shows all the keyboard shortcuts on screen, which makes it much easier for your colleagues to follow you and might teach them a trick or two.

I feel like Angular Developers need to hear this!
🗂 Splitting your code into multiple files doesn’t always mean better organization. Sometimes, it can actually make finding things more complicated.
There's a lot of cognitive overhead in "what goes in this file" or "where do I put this code" that seems unnecessary.

For all the #rxjs devs out there.
Do you think it would be helpful to add a section to the docs where we compare similar operators, e.g. switchmap & flatmap or *map in general
I'm really curious wether this would help devs to get into rxjs 👩💻

One thing I learned by looking at the implementation of
@ngrx_io signal store is that you can return a class reference to create "dynamic"/configurable services.
It is a very nice pattern to define more reusable service logic! Here I drafted an implementation for a resource service factory that needs some polishing but could be used to handle REST endpoints
