1. Server-Side Swift as a Live Example @tnantokaɹɹɹɹɹɹɹɹɹɹɹ
2. Server-Side Swift?
3. Yes!
4. Why?
5. "Because it's there."
6. No...
7. Why?
8. "No reason."
9. We Can Use → Rails → Go → Node → Scala ...
10. Why?
11. ns*.com → nsdateformatter.com → nsregularexpression.com
12. Server-Side Swift as a Live Example
13. Showcase
14. nsurl.serversideswift.net
15. stringfilter.herokuapp.com
16. sssaale-reversi.herokuapp.com
17. How to Make
18. Framework ⭐ Perfect 10700+ Vapor 8800+ Kitura 5300+
19. Environment → Xcode (auto-completion) → swiftdocker/docker-swift (Linux)
20. #if os(Linux) error: use of unresolved identifier 'NSRegularExpression' error: value of type 'NSURL' has no member 'isFileReferenceURL' error: cannot convert value of type 'NSMutableString' to expected argument type 'CFMutableString!' (›°□°)›ớᵲᴸᵲ
21. Hello, World!
22. sssaale.herokuapp.com
23. AppLogic/Droplet+Setup.swift // GET / -> Views/welcome.leaf drop.get { req in return try drop.view.make("welcome", [ "title": title ]) } // /example -> Controllers/ExampleController.swift drop.resource("example", ExampleController())
24. Models/Example.swift final class Example: Model { // Input -> Output var input: String var output: String { return input.uppercased() } // JSON -> Model init(node: Node, in context: Context) throws { input = try node.extract("input") } // Model -> JSON func makeNode(context: Context) throws -> Node { return try Node(node: [ "output": output, ]) } }
25. Controllers/ExampleController.swift final class ExampleController: ResourceRepresentable { // Model -> JSON func create(request: Request) throws -> ResponseRepresentable { let example = try request.example() return example } // POST /example -> create func makeResource() -> Resource<Example> { return Resource( store: create ) } }
26. AppLogicTests/AppLogicTests.swift func testExample() { let drop = try! makeTestDroplet() let json = try! JSON(node: .object([ "input" : "hello" ])) let req = try! Request( method: .post, uri: "/example", headers: [ HeaderKey.contentType : "application/json" ], body: json.makeBody() ) let res = try! drop.respond(to: req) let body = res.body.bytes!.string XCTAssertTrue(body.contains("HELLO")) // hello -> HELLO }
27. Live Coding
28. Create Project $ vapor new MarkdownEditor --template=tnantoka/sssaale $ cd MarkdownEditor $ vapor xcode -y
29. Package.swift + .Package( + url: "https://github.com/IBM-Swift/Kitura-Markdown.git", + majorVersion: 0, + minor: 8 + ),
30. Models/Example.swift + import KituraMarkdown - return input.uppercased() + return KituraMarkdown.render(from: input)
31. scripts/app.js - <input type="text + <textarea - { example.output } + <div + dangerouslySetInnerHTML={ + { __html: example.output } + } + />
32. AppLogicTests/AppLogicTests.swift - try! JSON(node: .object([ "input" : "hello" ])) + try! JSON(node: .object([ "input" : "# hello" ])) - XCTAssertTrue(body.contains("HELLO")) + XCTAssertTrue(body.contains("<h1>hello</h1>"))
33. Test & Run $ docker pull swiftdocker/swift $ docker run -it -v `pwd`:/app -w /app -p 8080:8080 swiftdocker/swift $ swift test $ .build/Debug/App
34. localhost:8080
35. Deploy $ vapor heroku init $ vapor heroku push
