q-http v0.1.16

Provides a Q promise API for HTTP requests and responses. This should resemble JSGI and its hypothetical inverse, but I haven't pored through the specification to ensure this.

The API

• Server(app)
  • accepts an application, returns a server.
  • calls the application function when requests are received.
    • if the application returns a response object, sends that response.
  • listen(port)
    • accepts a port number.
    • returns a promise for undefined when the server has begun listening.
  • stop()
    • returns a promise for undefined when the server has stopped.
• request(request)
  • accepts a request or a URL string.
  • returns a promise for a response.
• read(request)
  • accepts a request or a URL string.
  • returns a promise for the response body as a string provided that the request is successful with a 200 status.
    • rejects the promise with the response as the reason for failure if the request fails.
• normalizeRequest(request)
  • coerces URLs into request objects.
• normalizeResponse(response)
  • coerces strings, arrays, and other objects supporting forEach into proper response objects.
  • passes undefined through as a signal that a request will not receive a response directly.
• request
  • url the full URL of the request as a string
  • path the full path as a string
  • scriptName the routed portion of the path, like "" for http://example.com/ if no routing has occurred.
  • pathInfo the part of the path that remains to be routed, like / for http://example.com or http://example.com/ if no routing has occurred.
  • version the requested HTTP version as an array of strings.
  • method like "GET"
  • scheme like "http:"
  • host like "example.com"
  • port the port number, like 80
  • remoteHost
  • remotePort
  • headers corresponding values, possibly an array for multiple headers of the same name.
  • body
  • node the wrapped Node request object
• response
  • status the HTTP status code as a number, like 200.
  • headers
  • body
  • onclose is an optional function that this library will call when a response concludes.
  • node the wrapped Node response object.
• headers are an object mapping lower-case header-names to corresponding values, possibly an array for multiple headers of the same name, for both requests and responses.
• body is a representation of a readable stream, either for the content of a request or a response.
  • forEach(callback)
    • accepts a callback(chunk) function
      • accepts a chunk as either a string or a Buffer
      • returns undefined or a promise for undefined when the chunk has been flushed.
    • returns undefined or a promise for undefined when the stream is finished writing.
    • the forEach function for arrays of strings or buffers is sufficient for user-provided bodies
  • the forEach function is the only necessary function for bodies provided to this library.
  • in addition to forEach, bodies provided by this library support the entire readable stream interface provided by q-io.
  • read()
    • returns a promise for the entire body as a string or a buffer.
• application
  • accepts a request
  • accepts Node's responder object as a second argument.
  • returns a response, a promise for a response, or nothing if no response should be sent.
