usage

one way binding

Automatically calls tag.update when dataObject is modified (recursively)

<my-tag>
  <script>
    var tag = this
    require('bind-tag')(tag)
    var dataObject = {
      property: {
        value: 42
      }
    }
    tag.bind('myState', dataObject)
    setInterval(function () {
      tag.myState.property.value += 1
    }, 1000)
  </script>
  <div>{myState.property.value}</div>
</my-tag>

two way binding

Automatically synchronizes dom elements' .value with dataObject

<my-tag>
  <script>
    var tag = this
    require('bind-tag')(tag)
    var dataObject = {
      property: {
        value: "42"
      }
    }
    tag.bind('myState', dataObject)
    tag.resetValue = function (e) {
      tag.myState.property.value = "42"
    }
    tag.printValue = function (e) {
      console.log(tag.myState.property.value)
    }
  </script>
  <input tag-value={bindProp('myState.property.value')} />
  <button onclick={resetValue}>reset value</button>
  <button onclick={printValue}>print vlaue</button>
</my-tag>
