npm install livewire

Livewire)

Streaming HTTP routing for Node.js. Best served with Oban and a dash of water. Built on Highland.

``bash npm install livewire`

`Example`

`livescript {route, get, post} = require \livewire {ok, not-found} = require \dram {body-params} = require \corps User = require \theoretical-user-model templates = require \theoretical-templater

route [ get '/' -> ok "hello" get '/user/:id' (req)-> User.get req.params.id .chain templates.user post '/user/:id' (req)-> params <- body-params JSON.parse, req .chain model <- User.get req.params.id .chain <- model.update params .save! .chain redirect '/user/#id' ]`

route returns a function that takes a request and returns a result Stream. Funnily enough, that's exactly the kind of function you serve with Oban. Have a look at Peat and Dram if you need fancy responses.

####

route : ∀a,b. [a → Stream b] → a → Stream b
Calls the functions in turn and returns the first nonempty stream. Given our handlers return empty streams for non-matching routes, this is sufficient to call the first matching route handler.

$3

#### respond : ∀a. Method → Path → (Request → Stream a) → Request → Stream a
Takes a string method and path, a handler, and a request, and gives back a stream for a response. If the method or the path don't match, the stream is empty, and you can switch to an alternate stream with .otherwise

#### get, post et al
Are just respond partially applied with the method.

$3

A simple string path matches exactly. If the last character is /, it matches a path prefix, unless the path is / exactly. Paths can contain parameters, which are of the form :ident. This match any non-/ string, and extract the value into req.params under the key given by the identifier.

Request body handling has been removed from Livewire 0.6, and split out into its own module, Corps.
