observ-array

An array containing observable values

Example

An ObservArray is an observable version of an array, every mutation of the array or mutation of an observable element in the array will cause the ObservArray to emit a new changed plain javascript array.

var ObservArray = require("observ-array")
var ObservHash = require("observ-hash")
var Observ = require("observ")
var uuid = require("uuid")

function createTodo(title) {
  return ObservHash({
    id: uuid(),
    title: Observ(title || ""),
    completed: Observ(false)
  })
}

var state = ObservHash({
  todos: ObservArray([
    createTodo("some todo"),
    createTodo("some other todo")
  ])
})

state(function (currState) {
  // currState.todos is a plain javascript todo
  // currState.todos[0] is a plain javascript value
  currState.todos.forEach(function (todo, index) {
    console.log("todo", todo.title, index)
  })
})

state.todos.get(0).title.set("some new title")
state.todos.push(createTodo("another todo"))
