gantt-elastic as vue component

Take a look at the vue.html inside examples folder file to see how you could add gantt-elastic inside <script> tag along with the Vue framework

Demo project: https://github.com/neuronetio/vue-gantt-elastic

You can also import gantt-elastic as compiled js component in commonjs or umd format (examples folder) or just grab GanttElastic.vue from src directory and add to your existing vue project.

import Vue from 'vue';
import GanttElastic from "gantt-elastic/src/GanttElastic.vue";
import Header from "gantt-elastic/src/components/Header.vue"; // if you want standard header
new Vue({
  el:'#gantt',
  template:`<gantt-elastic :tasks="tasks" :options="options">
    <gantt-elastic-header slot="header"></gantt-elastic-header>
    <gantt-elastic-footer slot="footer"></gantt-elastic-footer>
  </gantt-elastic>`,
  components: {
    ganttElasticHeader: {template:`<span>your header</span>`},// or Header
    ganttElastic: GanttElastic
    ganttElasticFooter: {template:`<span>your footer</span>`},
  },
  data() {
    return {
      tasks: tasks,
      options: options
    };
  }
});

or

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.

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');
