Using this library with Vapor. Possible?

[nashysolutions]

It seems my Vapor App target and Vapor Test target are both running and setting independent instances of 'DependencyValues'. The docs mention preventing an iOS App from executing code using the dynamic overlay library, which I may have to do with Vapor. This would however, prevent end to end testing, but won't be the end of the world.

Has anyone else had any success with Vapor + this library before?

@nashysolutions Hi! I use Dependencies + Vapor and find it very convenient. It's important to be careful: dependencies can escape sometimes and it leads to weird and hard debuggable bugs. To avoid escaping I use this middleware:

import Dependencies
import Foundation
import Vapor

public struct DependencyMiddleware: AsyncMiddleware {

	private let values: DependencyValues.Continuation

	public init() {
		values = withEscapedDependencies { $0 }
	}

	public func respond(to request: Request, chainingTo next: AsyncResponder) async throws -> Response {
		try await values.yield {
			try await withDependencies {
				$0.logger = request.logger
			} operation: {
				try await next.respond(to: request)
			}
		}
	}
}

Also I had to wrap websocket methods with withEscapedDependencies.
