+
+## Our Standards
+

+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism

+
+### Code of Conduct
+
+This project adheres to the Contributor Covenant [code of conduct](CODE_OF_CONDUCT.md).
+By participating, you are expected to uphold this code.
+Please report unacceptable behavior to [contact@digipolitan.com](mailto:contact@digipolitan.com).
+
+### Reporting Bugs
+
+This section guides you through submitting a bug report for Digipolitan. Following these guidelines helps maintainers and the community understand your report :pencil:, reproduce the behavior :computer: :computer:, and find related reports :mag_right:.
+
+Before creating bug reports, please check [this list](#before-submitting-a-bug-report) as you might find out that you don't need to create one. When you are creating a bug report, please [include as many details as possible](#how-do-i-submit-a-good-bug-report). If you'd like, you can use [this template](#template-for-submitting-bug-reports) to structure the information.
+
+#### Before Submitting A Bug Report
+
+* **Perform a [search](https://github.com/issues?q=+is%3Aissue+user%3Adigipolitan)** to see if the problem has already been reported. If it has, add a comment to the existing issue instead of opening a new one.
+
+#### How Do I Submit A (Good) Bug Report?
+
+Bugs are tracked as [GitHub issues](https://guides.github.com/features/issues/). After you've determined
+
+Explain the problem and include additional details to help maintainers reproduce the problem:
+
+* **Use a clear and descriptive title** for the issue to identify the problem.
+* **Describe the exact steps which reproduce the problem** in as many details as possible.
+* **Provide specific examples to demonstrate the steps**. Include links to files or GitHub projects, or copy/pasteable snippets, which you use in those examples. If you're providing snippets in the issue, use [Markdown code blocks](https://help.github.com/articles/markdown-basics/#multiple-lines).
+* **Describe the behavior you observed after following the steps** and point out what exactly is the problem with that behavior.
+* **Explain which behavior you expected to see instead and why.**
+* **Include screenshots and animated GIFs** which show you following the described steps and clearly demonstrate the problem.
+* **If you're reporting that perfect-middleware-swift crashed**, include a crash report with a stack trace from the operating system. On iOS, the crash report is available in Xcode, on macOS, the crash report will be available in `Console.app` under "Diagnostic and usage information" > "User diagnostic reports". Include the crash report in the issue in a [code block](https://help.github.com/articles/markdown-basics/#multiple-lines), a [file attachment](https://help.github.com/articles/file-attachments-on-issues-and-pull-requests/), or put it in a [gist](https://gist.github.com/) and provide link to that gist.
+* **If the problem is related to performance**, include a CPU profile capture and a screenshot with your report.
+* **If the problem wasn't triggered by a specific action**, describe what you were doing before the problem happened and share more information using the guidelines below.
+
+Provide more context by answering these questions:
+
+* **Did the problem start happening recently** (e.g. after updating to a new version of perfect-middleware-swift) or was this always a problem?
+* If the problem started happening recently, **can you reproduce the problem in an older version of perfect-middleware-swift ?** What's the most recent version in which the problem doesn't happen? You can download older versions of perfect-middleware-swift from [the releases page](https://github.com/digipolitan/perfect-middleware-swift/releases).
+* **Can you reliably reproduce the issue?** If not, provide details about how often the problem happens and under which conditions it normally happens.
+
+Include details about your configuration and environment:
+
+* **Which version of perfect-middleware-swift are you using?
+* **What's the name and version of the macOS or iOS you're using**?

-# perfect-middleware-swift
+DGPerfectMiddleware
+=================================
+
+[![Twitter](https://img.shields.io/badge/twitter-@Digipolitan-blue.svg?style=flat)](http://twitter.com/Digipolitan)
+
+Perfect middleware swift allows developer to register middlewares inside a Perfect HTTPServer
+
+## Installation
+
+### Swift Package Manager
+
+To install DGPerfectMiddleware with SPM, add the following lines to your `Package.swift`.
+
+```swift
+import PackageDescription
+
+let package = Package(
+    name: "XXX",
+    dependencies: [
+        .Package(url: "https://github.com/Digipolitan/perfect-middleware-swift.git", majorVersion: 1, minor: 0)
+    ]
+)
+```
+
+## The Basics
+
+Create an HTTPServer and register routes in the RouterMiddleware
+
+```swift
+let server = HTTPServer()
+
+let router = RouterMiddleware()
+
+router.get(path: "/") { (context) in
+    context.response.setBody(string: "It Works !").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)")
+}
+```
+
+Passing data between middlewares, you can provide 2 or more middleware for the same route and shared data across each middleware using the context
+
+```swift
+router.get(path: "/") { (context) in
+    context["name"] = "Steve"
+    context.next()
+}
+
+router.get(path: "/") { (context) in
+    guard let name = context["name"] as? String else {
+        return
+    }
+    context.response.setBody(string: "hello mr. \(name)!").completed()
+    context.next()
+}
+```
+
+It's possible to create and register Middleware subsclasses instead of closures
+
+```swift
+class RandomMiddleware: Middleware {
+
+    func handle(context: RouteContext) throws {
+        context["rand"] = arc4random()
+        context.next()
+    }
+}
+```
+
+Register Middleware as follow :
+
+```swift
+router.post(path: "/random", middleware: RandomMiddleware())
+
+router.post(path: "/random") { (context) in
+    guard let rand = context["rand"] as? UInt32 else {
+        return
+    }
+    context.response.setBody(string: "the result \(rand)").completed()
+    context.next()
+}
+```
+
+## Advanced
+
+### Register middleware for all routes
+
+it's possible to register middlewares before & after all child routes of the router
+
+```swift
+router.use(event: .beforeAll) { (context) in
+    context["start_date"] = Date()
+    context.next()
+}.use(event: .afterAll) { (context) in
+    guard let startDate = context["start_date"] as? Date else {
+        return
+    }
+    let duration = Date().timeIntervalSince1970 - startDate.timeIntervalSince1970
+    print(String(duration * 1000) + " ms")
+    context.next()
+}
+```
+
+This code will print the duration in second of the process for each route
+
+### 404 handler
+
+```swift
+router.use(event: .notFound) { (context) in
+    context.response.setBody(string: "404").completed()
+    context.next()
+}
+```
+
+### Error handler
+
+```swift
+router.use { (err, context) in
+    context.response.setBody(string: err.localizedDescription).completed()
+    context.next()
+}
+```
+
+### Register sub routers
+
+This code print "My name is" by calling "/user/name" path in your server
+
+```swift
+let router = RouterMiddleware()
+
+let childRouter = RouterMiddleware()
+
+childRouter.get(path: "/name") { (context) in
+    context.response.setBody(string: "My name is").completed()
+    context.next()
+}
+
+router.use(path: "/user", router: childRouter)
+
+server.use(router: router)
+```
