KituraContracts
Summary
KituraContracts is a library containing type definitions shared by client (e.g. KituraKit) and server (e.g. Kitura) code. These shared type definitions include Codable Closure Aliases, RequestError, QueryEncoder, QueryDecoder, Coder, Identifier Protocol and Extensions to String and Int, which add conformity to the Identifier protocol.
Usage
KituraContracts represents the types and protocols that are common to both the Kitura server and KituraKit client side library. If you are using Kitura or KituraKit, your project does not need to depend on KituraContracts explicitly.
Add dependencies
Add the KituraContracts
package to the dependencies within your application’s Package.swift
file. Substitute "x.x.x"
with the latest KituraContracts
release.
.package(url: "https://github.com/Kitura-Next/KituraContracts.git", from: "x.x.x")
Add KituraContracts
to your target’s dependencies:
.target(name: "example", dependencies: ["KituraContracts"]),
Import package
import KituraContracts
Example
This example, shows how to use a shared type definition for RequestError
within a router POST method on users
. If no errors occurred and you have a User
you can respond with the user and pass nil as the RequestError?
value. If there has been an error you can respond with an appropriate error and pass nil for the User?
.
public struct User: Codable {
...
}
router.post("/users") { (user: User, respondWith: (User?, RequestError?) -> Void) in
if databaseConnectionIsOk {
...
respondWith(user, nil)
} else {
...
respondWith(nil, .internalServerError)
}
}
