Configuration

This is an example with a minimal use of the VirtualList component

import React from "react";
import ReactDOM from "react-dom";
import VirtualList from "react-vlist";
import "./Application.css";

const data = [{ name: "hola" }];
for (let i = 0; i < 1000; i++) {
  data.push({ name: `Row ${i}` });
}
function App() {
  return (
    <div className="app-container">
      <h1>Virtual List</h1>
      <VirtualList
        className="list"
        data={data}
        itemheight={50}
        renderItems={(item, index, style) => (
          <div className="itemRenderer" key={index} style={style}>
            <img
              className="itemImage"
              src="https://i.stack.imgur.com/4QkvN.jpg?s=64&g=1"
            />
            <div className="itemTitleContainer">
              <div className="itemTitle">{item.name}</div>
              <div className="itemContent">{item.name}</div>
            </div>
          </div>
        )}
      />
    </div>
  );
}

const rootElement = document.getElementById("root");
ReactDOM.render(<App />, rootElement);

So the first thing is to create some data

const data = [{ name: "hola" }];
for (let i = 0; i < 1000; i++) {
  data.push({ name: `Row ${i}` });
}

The next thing we implement a render method that use the list.

 <VirtualList
        className="list"
        data={data}
        itemheight={50}
        renderItems={(item, index, style) => (
          <div className="itemRenderer" key={index} style={style}>
            <img
              className="itemImage"
              src="https://i.stack.imgur.com/4QkvN.jpg?s=64&g=1"
            />
            <div className="itemTitleContainer">
              <div className="itemTitle">{item.name}</div>
              <div className="itemContent">{item.name}</div>
            </div>
          </div>
        )}
      />

The list recive 3 params:

data: Data is an array of elements to be render by the list
itemheight: is the height of each item of the list
renderItems: It is a hight order function where you can set what component is to be use to render the list elements.
- The function recive the following params:
  - item:A element from the data object.
  - index:The cardinal order of the element, it positio in the data array.
  - style:The style to be applied to position the element.
- This function returns:
  - A react component.(Make sure you assign the style to the returning component so it get position properly)
