## Gantt-elastic
is a vue component but it could be used in other frameworks or even with jQuery (vue is kind of elastic and lightweight framework).

gantt-elastic is not fully finished yet and may change (not released yet)

### Full documentation soon - if you can motivate me (leave a :star:)

For now you can look at [WIKI](https://github.com/neuronetio/gantt-elastic/wiki)

### Installation
`npm install --save gantt-elastic` or download zip from github / clone repo

### Standalone usage (vue.js bundled along with gantt-elastic component) for other frameworks like jQuery or pure vanilla js apps

### gantt-elastic as vue component

Take a look at the `vue.html` inside [examples folder](https://github.com/neuronetio/gantt-elastic/tree/master/examples)  file to see how you could add gantt-elastic inside `<script>` tag along with the Vue framework

You can also import gantt-elastic as compiled js component in commonjs or umd format ([examples](https://github.com/neuronetio/gantt-elastic/tree/master/examples) folder) or just grab GanttElastic.vue from src directory and add to your existing vue project.

```javascript
import Vue from 'vue';
import GanttElastic from "gantt-elastic/src/GanttElastic.vue";
new Vue({
  el:'#gantt',
  template:`<gantt-elastic :tasks="tasks" :options="options"></gantt-elastic>`,
  components: {
    ganttElastic: GanttElastic
  },
  data() {
    return {
      tasks: tasks,
      options: options
    };
  }
});
```
or
```javascript
import Vue from 'vue';
import App from './App.vue'; // your app that uses gantt-elastic from 'gantt-elastic/src/GanttElastic.vue'

new Vue({
  el: '#app',
  render: h => h(App),
});
```

### For webpack usage (pure javascript, inside other frameworks or Vue App/Component)

Take a look at this demo project: https://github.com/neuronetio/gantt-elastic-webpack for other bundlers use umd or commonjs from dist folder.

```javascript
import GanttElastic from 'gant-elastic/dist/GantElastic.umd.js';
import GanttElastic from 'gant-elastic/dist/GantElastic.common.js'; // same as import GanttElastic from 'gantt-elastic';
import GanttElastic from 'gantt-elastic/src/GantElastic.vue'; // if you want vue component directly without compilation - look above
// and the same with require
const GanttElastic = require('gant-elastic/dist/GantElastic.common.js');
```

### uglifyjs

If you are using uglifyjs in your project be sure to have es6 compatible version like [uglify-es](https://www.npmjs.com/package/uglify-es)
