Example Implementation

Here is how to set up a basic Swift Vapor application with envvault:

// main.swift
import Vapor

// Your environment variables are automatically loaded
let port = Environment.get("PORT") ?? "8080"
let dbUrl = Environment.get("DB_URL") ?? ""

let app = try Application(.detect())
defer { app.shutdown() }

app.get { req async -> String in
    return "Hello from envvault!"
}

try app.server.start(hostname: "127.0.0.1", port: Int(port) ?? 8080)
defer { app.server.shutdown() }
try app.run()

// Package.swift
// swift-tools-version:5.5
import PackageDescription

let package = Package(
    name: "MyApp",
    dependencies: [
        .package(url: "https://github.com/vapor/vapor.git", from: "4.0.0"),
    ],
    targets: [
        .target(name: "App", dependencies: [.product(name: "Vapor", package: "vapor")])
    ]
)
