view-list

An infinite scrolling list view element built on a virtual DOM.

Example

View a live example displaying 200k rows: http://shama.github.io/view-list

Render the ViewList using virtual-dom:

var ViewList = require('view-list')

// Create an instance of our view list in document.body
var viewlist = new ViewList({
  appendTo: document.body
})

// Create some data to add to the list
var data = ['one', 'two', 'three']

// Render the data
viewlist.render(data)

// Listen for scroll events coming up
viewlist.addEventListener('scroll', function (element) {
  console.log('List was scrolled to ' + element.scrollTop)
})

// Every second, append a new row
var i = 0
setInterval(function() {
  data.push('row ' + i++)
  viewlist.render(data)
}, 1000)
