Web Server components for NoFlo

This module provides NoFlo components for running HTTP servers and handling HTTP requests.

Components

• webserver/Server — starts an HTTP server per received port, emitting a scoped request/response pair per incoming request
• webserver/BodyParser — parses JSON and urlencoded request bodies into req.body (via body-parser)
• webserver/Query — parses the request URL's query string into req.query (Web-standard URL/URLSearchParams)
• webserver/WriteHead — writes a status code and headers to the response
• webserver/WriteResponse — writes a string (or stream of strings) to the response
• webserver/SendResponse — ends the response

For practical needs, the higher-level noflo-xpress library is recommended.

Usage

Components are discovered automatically by NoFlo 2.x on Node.js. Example in FBP:

WebServer(webserver/Server) LISTENING -> IN WriteHead
8080 -> LISTEN WebServer
WebServer REQUEST -> IN BodyParser OUT -> IN Query OUT -> IN WriteResponse
'Hello world!' -> STRING WriteResponse OUT -> IN SendResponse
