what

Collection of helper methods for reactions within http and websocket context

why

Using node-organic core and Organelles based implementation of business logic usually needs helper functions to be able to express reactive logic in managable way.

In general this is an experiment of Continuation implementation in nodejs related to organic ecosystem.

how

var http_chain = require("organic-alchemy").http.chain

var httpReaction = http_chain( 
  function(req, res, next) {
    // ...
    next && next()
  },
  function(req, res, next) {
    // ....
  },
  ....
)

httpReaction({
  req: HttpRequest,
  res: HttpResponse
}, function(){
  // reaction completed
})
var ws_chain = require("organic-alchemy").ws.chain

var wsReaction = ws_chain( 
  function(c, next) {
    // c.socket ...
    next && next()
  },
  function(c, next) {
    // c.socket ...
    next && next()
  },
  ....
)

wsReaction({
  socket: WebSocketConnection,
  name: EventName,
  data: EventData
}, function(){
  // reaction completed
})

todo

  • change behaviour support of 'next' in reactions at alchemy.http.chain so that it assigns to res. the given arguments/results
