react-lazy-list

This is a simple and fast realization of lazy list as the react component that show entities only when user can see them. Thats why it can render very large lists and does not lose performance.

import React, { Component } from 'react'
import LazyList from 'react-lazy-list'
 
export default class App extends Component {
  render() {
    const onMoreHandle = () => void
    return (
      <LazyList elementHeight={ 300 } onMore={ this.onMoreHandle } >
        { entities.map(entity => (
          <Item key={ entity.id } entity={ entity } />
        )) }
        <Dummy />
      </LazyList>
    )
  }
}
