Vapor Simple REST API

import Vapor

struct Todo: Content {
    var id: UUID?
    var title: String
    var completed: Bool
}

var todos: [Todo] = []

func routes(_ app: Application) throws {
    app.get("/todos") { req -> [Todo] in
        return todos
    }

    app.post("/todos") { req -> Todo in
        let todo = try req.content.decode(Todo.self)
        todos.append(todo)
        return todo
    }
}

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

Demonstrates a simple Vapor application with routes for listing and creating Todo items.

Frequently Asked Questions about Vapor

What is Vapor?

Vapor is a server-side Swift web framework designed for building fast, safe, and scalable web applications and APIs, fully leveraging Swift’s type safety and performance.

What are the primary use cases for Vapor?

Server-side Swift web applications. RESTful APIs and microservices. Backend for iOS/macOS apps. Real-time applications using WebSockets. Cloud-native services deployed on Vapor Cloud or Docker

What are the strengths of Vapor?

Type-safe and performant due to Swift. Native async support for high concurrency. Modular architecture and easy extension. Good integration with Apple ecosystem. Scales well for microservices and cloud deployments

What are the limitations of Vapor?

Smaller ecosystem compared to Node.js or Python frameworks. Requires Swift runtime on server. Fewer third-party tutorials and libraries. Not ideal for teams unfamiliar with Swift. Relatively newer, so enterprise adoption is smaller

How can I practice Vapor typing speed?
