Users debate whether Discord's migration from Electron to a native Rust stack justifies the loss of cross-platform development efficiency and accessibility features for perceived gains in memory usage. Critics argue that web frameworks waste system resources, while defenders highlight the value of consistent visuals and reduced developer man-hours.

This is awesome and I'm glad things are moving in this direction. I've been playing with Crux (Rust + Native UI) myself: https://github.com/redbadger/crux
In We should be more ambitious with the software we buildhttps://github.com/redbadger/crux
Native UI with Crux backend. Best of both worlds.
In Tsrs: A Port of TypeScript to RustLove seeing real native apps (vs electron hogs), starred. For heavy lifting and easier cross platform, Rust-based Crux is pretty cool, I'm experimenting with it now: https://github.com/redbadger/crux
In Show HN: Palmier Pro – Open-source macOS video editor built for AINeat, didn't realize this existed. I'm experimenting the Rust Crux (https://github.com/redbadger/crux) for this - uses the Elm pattern.
In Hologram Works. Sponsor What Comes NextBeen kicking around a similar idea in the back of my mind from the first moment "functional core / imperative shell" [0] and "sans-IO" [1] infected my brain. I've been chasing that high ever since.
Unfortunately, whenever I try to apply this pattern 100%, I hit all kinds of walls: language isn't expressive enough to support what I want; the amount of wiring/glue to support it becomes a burden; the resulting code is spaghetti because the "declaration of intent" lives too far from "implementation of the intent"; "oops I invented my Nth leaky DSL"; and so on and so on. Part of the problem is certainly my own capabilities as a developer as well.
I can't help but fantasize about the platonic ideal of a "perfect" system where all that nasty evil I/O is banished to the Shadow Realm and I can frolic in the Fields of Idempotency and Reproduciblity
Read the rest
-- one of these days I'll bite the bullet and try Haskell.
Nowadays I aim for 80% "perfection", and only in the areas where it matters. In addition, instead of effects I rely more on "reduce complexity as much as possible", which is (frustratingly) much harder to put into practice than "use X library/pattern to solve all problems". Though if I can model the system as a state machine and proptest it [2], that usually gets me where I want to be.
Though my soul feels like I just woke up from a dream where I was perfectly content, and now I'm back in the real world with all of its imperfections [3].
---
As for your specific project, it heavily reminds me of the Crux [4] model, which is itself inspired by Elm [5]. Also Flawless [6]. I wish you the best of luck with it.
