react-virtualized

Pros of Virtual

• Framework-agnostic, supporting React, Vue, Solid, and more
• More flexible API with customizable options for various virtualization scenarios
• Smaller bundle size and improved performance

Cons of Virtual

• Steeper learning curve due to more complex API
• Less mature ecosystem with fewer pre-built components
• May require more manual configuration for some use cases

Code Comparison

React-virtualized:

import { List } from 'react-virtualized';

<List
  width={300}
  height={300}
  rowCount={1000}
  rowHeight={20}
  rowRenderer={({ index, key, style }) => (
    <div key={key} style={style}>Row {index}</div>
  )}
/>

Virtual:

import { useVirtual } from '@tanstack/react-virtual';

const { virtualItems, totalSize } = useVirtual({
  size: 1000,
  parentRef: parentRef,
  estimateSize: () => 20,
});

<div ref={parentRef} style={{ height: '300px', overflow: 'auto' }}>
  <div style={{ height: `${totalSize}px` }}>
    {virtualItems.map(virtualRow => (
      <div key={virtualRow.index} style={{ height: `${virtualRow.size}px`, transform: `translateY(${virtualRow.start}px)` }}>
        Row {virtualRow.index}
      </div>
    ))}
  </div>
</div>

Both libraries offer efficient virtualization for large lists, but Virtual provides more flexibility at the cost of increased complexity. React-virtualized offers a simpler API with pre-built components, while Virtual allows for more customization across different frameworks.

Pros of react-window

• Smaller bundle size (approximately 1/3 the size of react-virtualized)
• Simpler API with fewer components, making it easier to learn and use
• Better performance due to reduced overhead and optimized rendering

Cons of react-window

• Fewer features compared to react-virtualized (e.g., no support for multi-directional scrolling or cell measuring)
• Less flexibility in customization options
• Might require additional work to implement some advanced use cases

Code Comparison

react-virtualized:

import { List } from 'react-virtualized';

<List
  width={300}
  height={300}
  rowCount={1000}
  rowHeight={20}
  rowRenderer={({ index, key, style }) => (
    <div key={key} style={style}>
      Row {index}
    </div>
  )}
/>

react-window:

import { FixedSizeList } from 'react-window';

<FixedSizeList
  height={300}
  width={300}
  itemCount={1000}
  itemSize={20}
>
  {({ index, style }) => (
    <div style={style}>Row {index}</div>
  )}
</FixedSizeList>

The code comparison shows that react-window has a slightly simpler API, with fewer props and a more straightforward implementation. However, both libraries achieve similar results in terms of rendering large lists efficiently.

Pros of react-virtuoso

• Simpler API with fewer components, making it easier to use and integrate
• Better support for dynamic content and variable-sized items
• More frequent updates and active maintenance

Cons of react-virtuoso

• Less mature and battle-tested compared to react-virtualized
• Fewer additional features and utilities beyond core virtualization

Code Comparison

react-virtualized:

import { List } from 'react-virtualized';

<List
  width={300}
  height={300}
  rowCount={1000}
  rowHeight={20}
  rowRenderer={({ index, key, style }) => (
    <div key={key} style={style}>Row {index}</div>
  )}
/>

react-virtuoso:

import { Virtuoso } from 'react-virtuoso';

<Virtuoso
  style={{ height: '300px', width: '300px' }}
  totalCount={1000}
  itemContent={index => <div>Row {index}</div>}
/>

Both libraries provide efficient rendering of large lists, but react-virtuoso offers a more straightforward API. react-virtualized requires explicit width, height, and rowHeight props, while react-virtuoso can infer these values in many cases. react-virtuoso's itemContent prop is more flexible than react-virtualized's rowRenderer, especially for variable-sized items.

react-virtualized has been around longer and offers additional components like Grid and Table, which may be beneficial for complex use cases. However, react-virtuoso's simpler API and better support for dynamic content make it an attractive option for many projects, especially those with varying item sizes or frequently changing data.

Pros of Virtual

• Framework-agnostic, supporting React, Vue, Solid, and more
• More flexible API with customizable options for various virtualization scenarios
• Smaller bundle size and improved performance

Cons of Virtual

• Steeper learning curve due to more complex API
• Less mature ecosystem with fewer pre-built components
• May require more manual configuration for some use cases

<div ref={parentRef} style={{ height: '300px', overflow: 'auto' }}>
  <div style={{ height: `${totalSize}px` }}>
    {virtualItems.map(virtualRow => (
      <div key={virtualRow.index} style={{ height: `${virtualRow.size}px`, transform: `translateY(${virtualRow.start}px)` }}>
        Row {virtualRow.index}
      </div>
    ))}
  </div>
</div>

Both libraries offer efficient virtualization for large lists, but Virtual provides more flexibility at the cost of increased complexity. React-virtualized offers a simpler API with pre-built components, while Virtual allows for more customization across different frameworks.

Pros of react-tiny-virtual-list

• Lightweight and focused: Smaller bundle size, specifically designed for simple list virtualization
• Simpler API: Easier to set up and use for basic virtualization needs
• Better performance for simpler use cases: Optimized for straightforward list rendering

Cons of react-tiny-virtual-list

• Limited features: Lacks advanced functionalities like grid layouts, scrolling utilities, and cell measuring
• Less flexibility: May not be suitable for complex virtualization scenarios
• Smaller community and ecosystem: Fewer resources, plugins, and third-party integrations available

Code Comparison

react-virtualized:

import { List } from 'react-virtualized';

<List
  width={300}
  height={300}
  rowCount={1000}
  rowHeight={20}
  rowRenderer={({ index, style }) => (
    <div style={style}>Row {index}</div>
  )}
/>

react-tiny-virtual-list:

import VirtualList from 'react-tiny-virtual-list';

<VirtualList
  width={300}
  height={300}
  itemCount={1000}
  itemSize={20}
  renderItem={({ index, style }) => (
    <div style={style}>Row {index}</div>
  )}
/>

Both libraries offer similar basic functionality, but react-virtualized provides more advanced features and customization options, while react-tiny-virtual-list focuses on simplicity and lightweight implementation for basic list virtualization needs.
