PerfectBlink

Perfect Blink middleware swift is a request parser

Parse incoming request body, query, url parameters before the route handler, data available under the context.blink.

Installation

Swift Package Manager

To install PerfectBlink with SPM, add the following lines to your Package.swift.

import PackageDescription

let package = Package(
    name: "XXX",
    dependencies: [
        .Package(url: "https://github.com/Digipolitan/perfect-blink-swift.git", majorVersion: 1)
    ]
)

The Basics

Create a RouterMiddleware and register the blink middleware before all routes handlers

let server = HTTPServer()

let router = RouterMiddleware()

router.use(event: .beforeAll, middleware: Blink.shared)

router.post(path: "/").bind { (context) in
  guard let body = context.blink.body as? [String: Any],
        let name = body["name"] as? String else {
        context.next()
        return
    }
    context.response.setBody(string: name).completed()
    context.next()
}

server.use(router: router)

server.serverPort = 8887

do {
    try server.start()
    print("Server listening on port \(server.serverPort)")
} catch PerfectError.networkError(let err, let msg) {
    print("Network error thrown: \(err) \(msg)")
}

It's possible to register a specific type to parse for only one route as follow :

router.post(path: "/")
  .bind(Blink.shared.json())
  .bind { (context) in
    guard let body = context.blink.body as? [String: Any] {
      context.next()
      return
    }
    print(body)
    context.next()
}

You can parse query parameters and url parameters for only one route as follow :

router.get(path: "/")
  .bind(Blink.shared.query())
  .bind(Blink.shared.params())
  .bind { (context) in
    guard let query = context.blink.query,
      let name = query["name"] {
      context.next()
      return
    }
    context.response.setBody(string: name).completed()
    context.next()
}
