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/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)
    }
}

Swift version

The 1.x.x releases were tested on macOS and Linux using the Swift 4.1 binaries. Please note that this is the default version of Swift that is included in Xcode 9.3.
