Sinatra about swifter HOT 17 CLOSED

hi @jchannon

I've not seen it yet.

I've just had a quick look at it looks like a nice source of:

• templates language support
• DSL for requests handling

I will take my time on this.

I contribute to a C# framework - http://nancyfx.org which is inspired from Sinatra

Would be good to see a Swift inspired fwk too 😄

@jchannon wow, I really like this:

Get["/greet/{name}"] = 

from swifter.

Lets do it! 😄

You could do it somewhat like this:

class HttpServer {
  enum Method : String {
    case Get    = "GET"
    case Head   = "HEAD"
    case Post   = "POST"
    case Put    = "PUT"
    case Delete = "DELETE"
  }

  struct Router {
    let method: Method

    var handlers: [(expression: NSRegularExpression, handler: Handler)] = []

    init(_ method: Method) {
      self.method = method
    }

    subscript(path: String) -> Handler? {
      get {
        return nil
      }
      set (newValue) {
        do {
          let regex = try NSRegularExpression(pattern: path, options: NSRegularExpressionOptions(rawValue: 0))
          if let handler = newValue {
            handlers.append(expression: regex, handler: handler)
          }
        } catch {

        }
      }
    }
  }

  var Get    = Router(.Get)
  var Head   = Router(.Head)
  var Post   = Router(.Post)
  var Put    = Router(.Put)
  var Delete = Router(.Delete)

  // ...
}

var server = HttpServer()

server.Get["/login"] = { ... }
server.Post["/login"] = { ... }

from swifter.

Of course you could also do it like Nancy:

class MyServer: HttpServer {
  override init() {
    super.init()

    Get["/login"] = { ... }
    Post["/login"] = { ... }
  }
}

from swifter.

Nice!!

Hi...are u still following the idea to make a Sinatra inspired swift version ?!

When apple finally releases Swift for linux then "swifter" would be perfect for creating micro services

@mwelser and @tristaaan Swifter will not work on Linux even after Swift is open sourced and ported because it depends on Foundation, which Apple will not port to Linux or open source.

@sdgandhi we are going to get rid of the dependencies - #60

Basic support for Sinatra routing has been added recently: df24ced

hi guys ( @jchannon @sdgandhi @tristaaan @mwelser @18601673727 @jchannon @jayrhynas @julien-c and others ! )

This thread is the main place for discussing routing mechanism so let me summarise what we already have an what's the bright future :)

With version 1.0.5 we have a support for the following routing mechanism:

Example 1 ( new ):

let server = HttpServer()
server.GET['/books/:id'] = { ... } // For GET http method.

Example 2 ( old - still supported ):

let server = HttpServer()
server['/books/:id'] = { ... }     // For any http method.

We also extracted IO part from HttpServer class to HttpServerIO class:

class HttpServerIO {
    // socket IO to accept connection {
    //  delegate request handling to select() function.
    // }
    ...
    public func select(...) {
        return ([:], { _ in HttpResponse.NotFound })
   }
}

class HttpServer: HttpServerIO {
    let router: HttpRouter()
    ...
    override public func select(....) {
        return router.select(....)
    }
}

As you can see the only task for HttpServer class is to expose the routing API and perform the routing. It means everybody can now create a new cool routing DSLs and add is as another MyHttpServer or make an extension for current HttpServer without making huge changes in HttpServer class:

extension HttpServer {
    ...
}

or

class MyServer: HttpServerIO {
     ...
}  

Below I got examples of the new ideas I've been thinking about:

let server = HttpServer()
server < users << :id  = {

}

or

enum Router  {
    case users( (Int) -> {

        })
}

from swifter.

Is it possible to use wildcard/regexp in routes?

Thanks and Happy Holidays!

hi @BeQ

Initially we supported regexps but we removed it :) Wildcard is supported. Please have a look at the example: https://github.com/glock45/swifter/blob/master/Sources/DemoServer.swift#L104
