npm install append-onlyAppend only scuttlebutt structure
Represent an append only data structure through scuttlebutt.
You push new pieces of data onto the list. You can also remove
a item from the list (which is actually an append only message).
append-only generates a unique __id on your item for you.
``js
var AppendOnly = require("append-only")
, list1 = AppendOnly()
, list2 = AppendOnly()
list1.on("item", function (item) {
if (item.more) {
list1.remove(item.__id)
}
})
list1.push({ some: "data" })
list1.push({ more: "data" })
list2.on("item", function (item) {
console.log("items", item)
})
list2.on("remove", function (item) {
console.log("item removed", item)
})
setTimeout(function () {
var array = list2.createArray()
console.log("array", array)
}, 500)
var stream1 = list1.createStream()
, stream2 = list2.createStream()
stream1.pipe(stream2).pipe(stream1)
