The Go crowd, like the Rust crowd, likes to advertise the language their software is written in. I agree that that specific sentence is a bit ambiguous, though, as if it's some kind of middleware that hooks into Go applications.

It's not, it's just another standalone reverse proxy.

Probably because end users appreciate that usually that means a single binary + config file and off you go. No dependency hell, setting up third party repos, etc.

Until you have to use some plugin (e.g. cloudflare to manage DNS for ACME checks), now it's exactly "dependency hell, setting up third party repos, etc."

I also fully expect to see a few crashes from unchecked `err` in pretty much any Go software. Also, nginx qualifies for `single binary + config`, it's just NGINX is for infra people and Caddy is for application developers.

Fortunately I don't think any of that applies to Rust ;-)

Actually, all of it applies to rust. The only stable ABI in Rust is C-ABI and IMO at that point it stops being rust. Even dynamically loading rustlib in rust application is unsafe and only expected to work when both compiled with the same version. In plugins context, it's the same as what Caddy making you do.

However, Rust Evangelical Strike Force successfully infiltrated WASM committee and when WASM Components stabilize, it can be used for plugins in some cases (see Zed and zellij). (Go can use them as well, rust is just the first (only?) to support preview-2 components model.

Yeah, I don't really do dynamic loading in my corner of Rust. And I can always target some MSRV, cargo package versions, and be happy with it. Definitely beats the dependency hell I've had to deal with elsewhere

Don't get me wrong, I love rust and use it almost every day. Doing `cargo run` in a project it handles everything is good. This gets lost once you start working in a plugin context. Because now you're not dealing in your neatly organized workplace, you're working across multiple workplaces from different people.

IIRC it's more than just MSRV or even matching version exactly. It also requires flags that were used to compile rustc match (there is an escape hatch tho).

When I see software written in Go, I know that it has a very sad plugin support story.

Terraform providers seem to work pretty well, but as far as I know, they're basically separate executables and the main process communicates with them using sockets.

[0x457]

Yes, works very well for terraform. You probably can see why it's not going to work for a webserver?
