Swift Server with Vapor

I have tried Vapor, a server side swift project and I have presented it to my coworkers and this is my presentation.

Transcript

1. Server Side Swift Is that really real ?

4. Kitura Vapor Zewo Perfect Frameworks
5. Get Started ! $ ~/> mkdir TestVapor && cd TestVapor $ ~/TestVapor/> swift package init --type executable Creating library package: TestVapor ├── Package.swift ├── Sources │ └── main.swift └── Tests
6. $ ~/> vapor new Hello Cloning Template [Done] ├── Sources │ └── App │ └── Controllers │ └── Middleware │ └── Models │ └── main.swift ├── Public ├── Resources │ └── Views └── Package.swift Get Started ! $ ~/> mkdir TestVapor && cd TestVapor $ ~/TestVapor/> swift package init --type executable Creating library package: TestVapor ├── Package.swift ├── Sources │ └── main.swift └── Tests
7. Package Manager // Package.swift import PackageDescription let package = Package( name: "TestVapor", dependencies: [ .Package(url: "https://github.com/vapor/ vapor.git", majorVersion: 1, minor: 0) ] )
8. Package Manager // Package.swift import PackageDescription let package = Package( name: "TestVapor", dependencies: [ .Package(url: "https://github.com/vapor/ vapor.git", majorVersion: 1, minor: 0) ] ) $ swift build Cloning https://github.com/vapor/vapor.git $ swift package generate-xcodeproj generated: ./TestVapor.xcodeproj
9. Routing " // Main.swift import Vapor let drop = Droplet() drop.get("/hello") { _ in return "Hello Vapor" } drop.run()
10. #Running !
11. #Running !
12. Return JSON // Main.swift import Vapor let drop = Droplet() drop.get("hello" , String.self) { request, name in return try JSON(node: [ "message" : "\(name)" ]) } drop.run()
13. Return JSON // Main.swift import Vapor let drop = Droplet() drop.get("hello" , String.self) { request, name in return try JSON(node: [ "message" : "\(name)" ]) } drop.run()
14. Parse JSON // Main.swift import Vapor let drop = Droplet() drop.post("post") { request in guard let name = request.data["name"]?.string else { throw Abort.badRequest } return try JSON(node: [ "message": "Hello \(name)!" ]) } drop.run()
15. Parse JSON // Main.swift import Vapor let drop = Droplet() drop.post("post") { request in guard let name = request.data["name"]?.string else { throw Abort.badRequest } return try JSON(node: [ "message": "Hello \(name)!" ]) } drop.run()
