Installation

Swift Package Manager

You can install graphzahl-vapor-support via Swift Package Manager by adding the following line to your Package.swift:

import PackageDescription

let package = Package(
    [...]
    dependencies: [
        .package(url: "https://github.com/nerdsupremacist/graphzahl-vapor-support.git", from: "0.1.0-alpha.")
    ]
)

Usage

You can now add a Schema direetly to your APPs Routes:

enum HelloWorld: GraphQLSchema {
    class Query: QueryType {
        func greeting(name: String) -> String {
            return "Hello, \(name)"
        }
    }

    typealias Mutation = None
}

// Add the API to the Routes of your Vapor App
app.routes.graphql(path: "api", "graphql", use: HelloWorld.self)

And you can even add GraphiQL:

app.routes.graphql(path: "api", "graphql", use: HelloWorld.self, includeGraphiQL: true)

And in case you need to provide a ViewerContext, just pass a closure, that describes how to get the ViewerContext from the Request:

enum TodoApp: GraphQLSchema {
    typealias ViewerContext = LoggedInUser?

    class Query: QueryType {
        let user: LoggedInUser?
        
        func myTodos() -> [Todo]? {
            return user?.todosFromDB()
        }

        required init(viewerContext user: LoggedInUser?) {
            self.user = user
        }
    }

    typealias Mutation = None
}

app.routes.graphql(path: "api", "graphql", use: TodoApp.self, includeGraphiQL: true) { $0.db }
