server-side Swift web framework a backend for CRUD iOS App

Why Vapor?

Vapor is an open-source web framework written in Swift. It’s built on top of Apple’s SwiftNIO library to provide a powerful, asynchronous framework. Vapor allows you to build back-end applications for iOS apps, front-end web sites and stand-alone server applications.

Product Controller

• GET

    // GET request routes
    func index(req: Request) throws -> EventLoopFuture<[Product]> {
        return Product.query(on: req.db).all()
    }

• POST

 // POST request routes
   func create(req: Request) throws -> EventLoopFuture<HTTPStatus> {
       let products = try req.content.decode(Product.self)
       return products.save(on: req.db).transform(to: .ok)
   }

• PUT

// PUT request /products routes
  func update(req: Request) throws -> EventLoopFuture<HTTPStatus> {
      let products = try req.content.decode(Product.self)
      
      return Product.find(products.id, on: req.db)
          .unwrap(or: Abort(.notFound))
          .flatMap {
              $0.name = products.name
              $0.actual_price = products.actual_price
              $0.profit_price = products.profit_price
              $0.work_price = products.work_price
              $0.quantity = products.quantity
              return $0.update(on: req.db).transform(to: .ok)
          }
  }

• DELETE

// DELETE Request /products/id (UUID) routes
  func delete(req: Request) throws -> EventLoopFuture<HTTPStatus> {
      Product.find(req.parameters.get("productID"), on: req.db)
          .unwrap(or: Abort(.notFound))
          .flatMap { $0.delete(on: req.db)}
          .transform(to: .ok)
      
  }
