I decided to adventure myself in Tauri development for a personal project, I read the entire Rust official book and followed the exercises. When I first started developing it was like if nothing I learned helped for real life projects.
Now after getting betting up every single time I touch my project, it seems I’m catching things slowly.
But I’ve never seen such a hard modern language, I used C and C++ before and it’s incomparable.
You probably mean general purpose libraries, when it comes to libraries that need to interact with OS native APIs Tauri does the heavy lifting by implementing for all platforms including Android and iOS.
I mean every language is cross-platform at its core, even Node, but for more complex calls things get really tricky.
Go to crates.io, search for whatever you need. Most probably it will be multiplatform.
