1. Swift Superpowers FrenchKit 2019 8th October 2019 David Bonnet - @iGranDav
2. what swift can offer outside of Apple platforms? from an iOS developer perspective
3. write server-side code on top of Swift Standard Library cross-platform port of Foundation! https://github.com/apple/swift-corelibs-foundation you can !
4. struct Talk var id: Int var name: String var date: Date } {
5. struct Talk var id: Int var name: String var date: Date } { : Codable
6. struct Talk var id: Int var name: String var date: Date } : Codable { let encoder = JSONEncoder() { "name": "Origins of life", "date": 592131600, "id": 42 }
7. struct Talk var id: Int var name: String var date: Date } : Codable { let encoder = JSONEncoder() encoder.dateEncodingStrategy = .iso8601 { "name": "Origins of life", "date": "2019-10-07T09:00:00Z", "id": 42 }
8. struct Talk var id: Int var name: String var date: Date } : Codable { let encoder = JSONEncoder() encoder.dateEncodingStrategy = .iso8601 { "name": "Origins of life", "date": "2019-10-07T09:00:00Z", "id": 42 } ⚠ https://github.com/apple/swift-corelibs-foundation/blob/master/Docs/Status.md
9. KITURA VAPOR
10. VAPOR all the following applies to both, examples are using Vapor 3
11. use standard server services with swift ease of use! you can ! like the ones you hear every week
12. struct Talk: Codable { var id: Int var name: String var date: Date }
13. struct Talk: Codable { var id: Int var name: String var date: Date } PostgreSQL
14. struct Talk: Codable { var id: Int var name: String var date: Date } PostgreSQL Redis
15. struct Talk: Codable { var id: Int var name: String var date: Date } PostgreSQL Amazon WebServices Redis struct Talk: Codable { var id: Int var name: String var date: Date var imageUrl: String }
16. struct Talk: Codable { var id: Int var name: String var date: Date var imageUrl: String } PostgreSQL using vapor 3
17. struct Talk: Codable { var id: Int var name: String var date: Date var imageUrl: String } extension Talk: PostgreSQLModel {} PostgreSQL using vapor 3 ?
18. struct Talk: Codable { var id: Int var name: String var date: Date var imageUrl: String } extension Talk: PostgreSQLModel {} PostgreSQL using vapor 3 ? extension Talk: Migration {}
19. PostgreSQL using vapor 3 // GET /talks func getAll(_ req: Request) throws -> Future<[Talk]> { return Talk.query(on: req).all() }
20. PostgreSQL using vapor 3 // GET /talks func getAll(_ req: Request) throws -> Future<[Talk]> { return Talk.query(on: req).all() } // GET /talks?page=1&per=50 func getAllP(_ req: Request) throws -> Future<Paginated<Talk>> { let query = Talk.query(on: req) return try query.paginate(for: req) }
21. PostgreSQL using vapor 3 // GET /talks?q=Robert func getAllP(_ req: Request) throws -> Future<Paginated<Talk>> { var query = Talk.query(on: req) .filter(\.imageUrl != nil) .sort(\.dateCreated, .descending) if let searchQuery = try? req.query.get(String.self, at: "q") { query = query.filter(\.name, .ilike, "%\(searchQuery)%") } return try query.paginate(for: req) }
22. PostgreSQL using vapor 3 // POST /talks func create(_ req: Request, content: Talk.Create) throws -> Future<Talk> { let upload = try Storage.upload(bytes: content.imageData, fileName: content.filename, on: req) return upload.flatMap { imageUrl in let talk = Talk(name: content.name, date: content.date, imageUrl: imageUrl) return talk.save(on: req) } } Amazon WebServices
23. server side swift write server-side code on top of Foundation supports many existing services PostgreSQL / MySQL / MongoDB / ... redis cache support Third party services connectors like AWS S3 try! Swift Tokyo 2019 Swift Server Update by Tom Doron (Apple) # $
24. Wanna try? there is a classroom for that : please come and say hi David Bonnet - @iGranDav
