Vvlv NPM | npm.io

vvlv

vvlv component build with vue and rxjs

Selling Point

virtualList won't create or remove any DOM when you scroll the list, it will reuse the existing DOM and only change their position and data. But when you resize your window, you'll find the DOM's number is changed, so your virtual list will always have just right number of DOM.

Install

npm install --save vvlv

Usage

import {Component,Vue} from 'vue-property-decorator';
import virtualList from 'vvlv'
@Component({
  components: {
    virtualList
  }
})
export default class App extends Vue {

  data:Array<any> = [];

  mounted() {
    fetch('https://jsonplaceholder.typicode.com/photos')
      .then(res => res.json())
      .then(data => this.data = data)
      .catch(console.error);
  }

  render() {
    return (
      <div class="virtual-box">
        <virtual-list style="height: 100%;"
          list={this.data} options={{ height: 180 }}
            {...{
              scopedSlots: {
                default: item => {
                  return (
                    <div class="card" style="height: 180px;">
