Status: Experimental / In Progress

Define Dependencies

You can define a dependency to require the Application, Request or Database to be created.

extension AnalyzerDependency: ApplicationDependencyKey {
  public static func live(app: Application) -> Self { ... }
}
extension SearchDependency: RequestDependencyKey {
  static func live(request: Request) -> Self { ... }
}
extension TopicsClient: DatabaseDependencyKey {
  public static func live(db: Database) -> Self { ... }
}

Configure

// Configure custom dependencies to use
app.dependencies.use(\.analyzer)
app.dependencies.use(\.search)
app.dependencies.use(\.topicsClient)

// Wrap requests in middleware
app.middleware.use(WithDependenciesMiddleware())

Use in a Request

// Gain access to configured dependencies during a request.
try await request.yieldDependencies {
  // do work, all dependencies are here!
}

Use in an Application

// Use outside of request context, for example with Commands.
try await application.withDependencies {
  // do work, all dependencies are here!
}
