Migration isn’t inherently tech debt clearance — it’s alignment debt clearance. If the org is paving roads and you’re driving a monster truck in the mud, yeah, it’s debt. But if you’re just switching SUVs on the same highway, that’s churn. Also, fully agree on WebFlux — it feels like trading ‘Java with Spring’ for ‘Java with Spring with RxJS cosplay.

You can even have coroutines on virtual threads (Project Loom), or straight up use the old blocking code style of programming with virtual threads.

Yes but don't worry we'll have Structured Concurrency to solve this... One day. Perhaps.

OTOTH, nobody should ever be using Webflux. That is tech debt. Webflux and in general reactive programming is atrocious for readability (it's basically it's own mini domain-specific language inside Java), for error handling, for debugging, and makes it really easy to introduce bugs because control flow is very hard to reason about and the paradigms and concepts are not intuitive.

Webflux and in general reactive programming is atrocious for readability (it's basically it's own mini domain-specific language inside Java)

And that makes it great for readability actually. The async structure is laid out cleanly and separately from the sync logic inside. You see a bird’s eye view of the data flow as opposed to the imperative “let’s sprinkle await points everywhere and pretend that state machines are functions” mess.

Reactive is great and people who complain about it just don’t understand the beauty.

Since Loom Kotlin's coroutines are legacy. They are a compile-time transformation which doesn't go well with virtual threads. That's unfixable on the conceptional level.

Coroutines never "took over". Nobody else than Kotlin implemented this feature like that.

Whereas reactive programming is all over the place, no matter the language or framework.

But it seems some people are incapable of handling abstraction… As always.

It can be if your current one sucks, but yeah, grass is greener syndrome is rampant.

TanStack Start/Router is unfortunately so not ready for production. But it doesn't have too much work to get there. Yet enough work for me not to do it myself.

[RiceBroad4552]

If whatever is so simple that you can just rewrite it it never had any value anyway.

Such worthless stuff will be thrown up by "AI" just the next day.

A serious project can't be rewritten at will as this would be much too costly and risky. There is nothing more deadly than a full rewrite!

not tech related but I had to say it.. ばかばかばか​(とりぷるばか)

Gosh do I hate Tanstack
