# Standalone

Pioneer also come with first-party integration for a standalone server. This aims to make developing with Pioneer even faster by not having to worry about setting up the server.

Under the hood, the standalone server uses the Vapor integration.

import Pioneer

let server = Pioneer(
    schema: schema,
    resolver: Resolver(),
    websocketProtocol: .graphqlWs,
    introspection: true,
    playground: .sandbox
)

try server.standaloneServer()

# Configuration

The standalone server allow some configuration to be better suited for your use case and environment.

# Port, Host, and Env

Must be a valid port number and an Integer
Defaults to 4000

try server.standaloneServer(
    port: 8080
)

try server.standaloneServer(
    host: "0.0.0.0"

# CORS

Given that the standalone option is responsible setup the server, any middleware need to be configured by the function.

To allow CORS using a middleware, .standaloneServer function can take specified CORSMiddleware.Configuration.

try server.standaloneServer(
    port: 443,
    host: "0.0.0.0",
    env: "production",
    cors: .init(
        allowedOrigin: .all,
        allowedMethods: [.GET, .POST, .OPTIONS],
        allowedHeaders: [.accept, .authorization, .contentType, .origin, .xRequestedWith, .userAgent, .accessControlAllowOrigin]
    )  
)

# Context

Configuring context with the standalone server is identical with the Vapor integration.
