In practical perspectives, I’m mostly concerned about computer resources usage; I have computer resources constraints. So using Rust would benefit on that. But it is for a Web application backend. So, is it worth it having to learn Rust + Tokio + Axum, … in this specific situation? Also, that this is mostly for initially prototyping an application. Also considering if I add developers in the future, they would most likely not be familiar with Rust, but with more popular frameworks such as Node.
I think if you know Rust then I think Rust + async is going to perform better and consume less resources than NodeJS by a LOT. It should also work more reliably on embedded devices, or even docker containers because memory isn’t going up and down like a yoyo because of GC.
That said NodeJS is more immediate and might lend itself to better prototyping / RAD and you might not care enough about performance to justify using a compiled language. A lot of web servers aren’t doing enough that you would even notice a difference in performance.
Another reason for Rust might also be because it’s more energy efficient. I wish Amazon and other cloud services would put a heavier cost penalty on efficiency. I wonder how many cloud web apps are running bloated stacks to serve up content which could be done with a fraction of the energy.
