Nodes SSO 🔑

📦 Installation

Add NodesSSO to the package dependencies (in your Package.swift file):

dependencies: [
    ...,
    .package(url: "https://github.com/nodes-vapor/nodes-sso.git", from: "1.0.0")
]

as well as to your target (e.g. "App"):

targets: [
    ...
    .target(
        name: "App",
        dependencies: [... "NodesSSO" ...]
    ),
    ...
]

Install resources

Copy the NodesSSO folders from Resources/Views and Public from this repo and paste them into your project into the same directories. You can download this repo as a zip and then move the files into the mentioned directories.

🚀 Getting started

First make sure that you've imported NodesSSO everywhere it's needed:

import NodesSSO

Adding the provider

public func configure(_ config: inout Config, _ env: inout Environment, _ services: inout Services) throws {
    try services.register(NodesSSOProvider<MyNodesSSOAuthenticatableUser>(config: NodesSSOConfig(
        projectURL: "https://myproject.com",
        redirectURL: "https://url-for-sso.com",
        salt: "MY-SECRET-HASH-FOR-SSO",
        environment: env
    )))
}

There are also parameters for setting the routes that should enable SSO in your project. Have a look at the signature of NodesSSOConfig for more information.

Adding the SSO routes

Make sure to add the relevant Nodes SSO routes, e.g. in your configure.swift or routes.swift:

services.register(Router.self) { container -> EngineRouter in
    let router = EngineRouter.default()
    try router.useNodesSSORoutes(MyNodesSSOAuthenticatableUser.self, on: container)
    return router
}

Adding the Leaf tag

In order to render embed the SSO button, you will need to add the NodesSSO Leaf tag:

public func configure(_ config: inout Config, _ env: inout Environment, _ services: inout Services) throws {
    services.register { _ -> LeafTagConfig in
        var tags = LeafTagConfig.default()
        tags.useNodesSSOLeafTags()
        return tags
    }
}

Embedding the SSO button

On the page you want the NodesSSO button to appear, embed the sso-button leaf file:

#embed("NodesSSO/sso-button")

Conforming to NodesSSOAuthenticatable

The NodesSSOProvider is generic and requires a type that conforms to NodesSSOAuthenticatable. This protocol has one method that gets called when the SSO has finnished successfully:

public static func authenticated(_ user: AuthenticatedUser, req: Request) -> Future<Response>

Given this AuthenticatedUser the implementer can then look up the email and create the user if it doesn't exist, or if it does, log the user in automatically.
