alchemy-swift / alchemy Goto Github PK

Hi, I'm having some issues running the default full stack server.

I generated the project after downloading the alchemy tool using mint and creating the project with:

$ ~/.mint/bin/alchemy new AlchemyDemo

and choosing the server only option

and then running swift run and letting the dependencies download. When that's done, the server runs just fine, but only for the first request. Here's the traceback I see:

$ swift run 
[0/0] Build complete!

/Users/me/Developer/AlchemyDemo/.build/checkouts/swift-nio/Sources/NIOCore/ChannelPipeline.swift:1765: Precondition failed
zsh: trace trap  swift run

Any idea?

The following code

import Alchemy

struct App: Application {
    func boot() {
        get("/") { req in
            "Hello World!"
        }
    }
}

App.main()

Generates the error

Fusion/Container.swift:219: Fatal error: Unable to resolve service of type Queue! Perhaps it isn't registered?

This is with swift 5.4

Hi - just trying to have a look at alchemy and following the instructions to get started, but getting an error when installing.

Using Xcode 13 (is that the issue?)

Hey team,

Great work on Alchemy. Been toying with it and I see in the README there is supposed to be async/await support though I had to polyfill for 3.2.0 which is the latest release (unless I'm doing something wrong). Is there supposed to be a 4.0 release? I see Fusion has one late January.

Thanks,
Alejandro

Best wishes

This is a really elegant and thorough micro web framework. The API is pretty intuitive and the documentation is pretty easy to follow. This is a great addition to Server-Side Swift.
Good job to the authors and contributors of Alchemy. Keep it up 👍
