graf

Run a bunch of async and sync functions in some kind of order.

Example

var graf = require('graf')
var crypto = require('crypto')

function a(x, y) { return x + y }
function add() {
    return Array.prototype.slice.call(arguments).reduce(a)
}

function m(x, y) { return x * y }
function multiply() {
    return Array.prototype.slice.call(arguments).reduce(m)
}

var g = graf(
    {
        input: ['a', 'b', 'x'],
        nodes: {
            sum: {
                input: ['a', 'b'],
                syncFn: add
            },
            multiply: {
                input: ['sum', 'sum', 'randomInt'],
                syncFn: multiply
            },
            randomBytes: {
                input: ['x'],
                fn: crypto.randomBytes
            },
            randomInt: {
                input: ['randomBytes'],
                syncFn: function (bytes) {
                    return bytes.readUInt8(0)
                }
            },
            foo: {
                input: ['sum', 'randomInt'],
                syncFn: function (sum, int) {
                    console.log("sum: %d int: %d", sum, int)
                }
            }
        },
        output: 'multiply'
    }
)

g(3, 2, 1, console.log)

Obviously not ready for prime time
