 Vue wrapper for [`dragula`][1].
 
+## Status
+
+WIP attempting to make example work with Vue 2.x
+
+### Changelog
+
+- Changed life cycle method `ready` to `mounted`
+- Using `$nextTick` callback as recommended in Vue2 guide
+- Using `this.$dragula` to access dragula extension/plugin  via Vue prototype global inherited by components 
+
+### TODO
+
+Check new [directives API](https://vuejs.org/v2/guide/custom-directive.html) and modify as needed:
+
+`bind`: called only once, when the directive is first bound to the element. This is where you can do one-time setup work.
+
+`inserted`: called when the bound element has been inserted into its parent node (this only guarantees parent node presence, not necessarily in-document).
+
+`update`: called after the containing component has updated, but possibly before its children have updated. The directive’s value may or may not have changed, but you can skip unnecessary updates by comparing the binding’s current and old values (see below on hook arguments).
+
+`componentUpdated`: called after the containing component and its children have updated.
+
+`unbind`: called only once, when the directive is unbound from the element.
+
+
+Currently, `bind`, `update` and `unbind` hooks are used.

+Following npm scripts are included:

+- `npm run build` to build new distribution in `/dist`
+- `npm run dev` run example in dev mode
+- `npm run lint` lint code using ESlint

+    domReadyTime = Date.now() ;
+      
+    // First, check if it's a PRE and exit if not
+      var bodyChildren = document.body.childNodes ;
+```
+
+```
+Exception:
+TypeError: Cannot read property 'childNodes' of null at HTMLDocument.ready
+```       
+
+### Recommendations
+
+Basically, the example needs to use proper `.vue` templates to work as discussed [here](https://github.com/vuejs-templates/webpack/issues/215)
+
+So please update example to use webpack or better yet, create demo app using basic Vue2 setup with webpack :)  
+
+I've started such a [demo app](https://github.com/kristianmandrup/vue2-dragula-demo) but having problems :() 
+
+I don't yet understand the Vue2 plugin architecture! Please help out...
+
+### Vue 2 Plugin
+
+Trying to add dragula as a [Vue 2 plugin](https://vuejs.org/v2/guide/plugins.html)
+
+```js
+  // 3. inject some component options
+  Vue.mixin({
+    created: function () {
+      // something logic ...
+    }
+    ...
+  })
+  // 4. add an instance method
+  Vue.prototype.$myMethod = function (options) {
+    // something logic ...
+  }  
+```
+
+Looks correct to add `$dragula` to `Vue.prototype` as shown [here](https://github.com/aarondfrancis/vue-model/blob/master/src/VueModel.js#L99)
+
+```js
+function plugin (Vue, options = {}) {
+  if (plugin.installed) {
+    console.warn('[vue-dragula] already installed.')
+  }
+
+  console.log('Add Dragula plugin:', options)
+  VueDragula(Vue, options)
+}
+```
+
+
+We then call the function in `vue-dragula.js` which adds `$dragula` to `Vue.prototype` in accordance with Vue 2 specs on plugins.
+What is missing!?!?! WTF!!!
+
+```js
+export default function (Vue, options = {}) {
+  const service = new DragulaService(Vue)
+
+  let name = 'globalBag'
+  let drake
+
+  console.log('Adding Dragula as plugin...')
+  Vue.$dragula = {
+    options: service.setOptions.bind(service),
+    find: service.find.bind(service),
+    eventBus: service.eventBus
+  }
+  Vue.prototype.$dragula = Vue.$dragula 
+}
+```
