Hello, I was looking at WXT extension framework which supports multiple UI frameworks, but they are all JavaScript frameworks only. Is there any alternative way to write Firefox browser extension in a different language (like Rust / Python / Go, etc.) with minimal or no JavaScript, with a ok developer experience?
Transpilation to JavaScript is fine if it is well supported in Firefox with ok developer experience.
I also checked Dart but its support on Firefox does not seem great, like the extension only works on Chrome browsers.
Yes its kind of possible with F# and Fable. I did it a few years ago. I say kind of because its still transpiling to javascript.
You could write something in rust for WASM and have minimal JavaScript. Looks like there are no frameworks around this concept as far as I’m aware, but I don’t see why it wouldn’t work in Firefox.
Well, you could presumably at least use
web-sysfor interacting with the DOM andwasm-bindgenin general for generating the boilerplate.But yeah, there might not be a pre-made library for interacting with the extension API, so might need to write your own JS←→WASM bindings.
