Installation

  npm install react-gallery-grid

Usage/Examples

The only one requirement is: Every item of the grid should have "width" and "height" properties.

Source: data.ts

interface SizeType {
    width: number;
    height: number;
}

export const images: SizeType[] = [
    {
        url: 'image1.png',
        width: 470,
        height: 280,
    },
    {
        url: 'image2.png',
        width: 620,
        height: 1080,
    },
    ...
]

Basic usage: MyGallery.tsx

import { Gallery } from "react-gallery-grid";
import { images } from "data.ts";

function MyGallery() {
  return (
    <Gallery
      items={images}
      itemRenderer={({ item, size }) => (
        <img src={item.url} width={size.width} height={size.height} />
      )}
      rowHeightRange={{ min: 200, max: 350 }}
      gap={8}
      preserveAspectRatio={true}
    />
  );
}

Advanced usage:

"For everything you gain, you lose something else.” — Ralph Waldo Emerson

The same is true for our grid:

If we keep aspect ratio - we lose row height range.

In the example above we preserve the aspect ratio of our images and therefore not every row fits within the height range.

To strictly match the row height range, we should ignore the aspect ratio by setting preserveAspectRatio to false. In this case, we don't want our images to be distorted, so we can:

• Crop the images.
• Fit the images.
• Or perhaps something else; let me know :) We can achieve this in a simple way by using the object-fit CSS property.

import { Gallery } from 'react-gallery-grid';
import { images } from 'data.ts';

function CropOrFitGallery() {
    return (
        <Gallery
            preserveAspectRatio={false}
            rowHeightRange={{ min: 200, max: 350 }}
            items={images}
            itemRenderer={({ item, size }) => (
                <img
                    src={item.url}
                    width={size.width}
                    height={size.height}
                    //for cropping the image
                    style={{object-fit: 'cover'}}
                    //for fitting the image
                    style={{object-fit: 'contain'}}
                />
            )}
            gap={8}
        />
  )
}

P.S.: Sometimes it is not possible to use CSS for cropping\fitting images. So, the itemRenderer provides you with extra data, cropBox and fitBox, for every item."

Extra cool features:

1. Cut big images

Simetimes it is usefull to crop very long or very tall images. We can set up the itemRatioRange(Works only with preserveAspectRatio = false).

import { Gallery } from 'react-gallery-grid';
import { images } from 'data.ts';

function CropOrFitGallery() {
    // const aspectRatio = width/height;
    // 0.5 - means ratio 1:2
    // 2.0 - means ratio 2:1
    const itemRatioRange = {min: 0.5, max: 2.0};
    return (
        <Gallery
            itemRatioRange={itemRatioRange}
            preserveAspectRatio={false}
            items={images}
            itemRenderer={({ item, size }) => (
                <img
                    src={item.url}
                    width={size.width}
                    height={size.height}
                    style={{object-fit: 'cover'}}
                />
            )}
            rowHeightRange={{ min: 200, max: 350 }}
            gap={8}
        />
  )
}

2. Infinite scroll

For infinite scrolling of the gallery without losing performance, wrap it in the scroll element and pass its ref to the Gallery scrollRef prop.

import { Gallery } from "react-gallery-grid";
import { images } from "data.ts";
import MyScroll from "./MyScroll.tsx";

function InfiniteGallery() {
  const scrollRef = React.useRef(null);

  return (
    <MyScroll ref={scrollRef}>
      <Gallery
        scrollRef={scrollRef}
        items={images}
        itemRenderer={({ item, size }) => (
          <img src={item.url} width={size.width} height={size.height} />
        )}
        rowHeightRange={{ min: 200, max: 350 }}
      />
    </MyScroll>
  );
}

API

type SizeType = {width: number, height: number};

type BoxType = {width: number, height: number, left: number, top: number};

props:

| Prop | Type | Description | | :------------------ | :-------------------------------------------------- | :------------------------------------------------------------------------------------------------------------ | | items | SizeType[] | Required. Items need to be placed into the rows. Each item should have 'width' and 'height' properties. | | itemRenderer | (props) => any | Required. Renderer for every item where in props you can get extra info about the item and its size. | | rowHeightRange | {min: number, max: number} | Optional. Minimum and maximum row heights. Works when preserveAspectRatio is set to false. | | itemRatioRange | {min: number, max: number} | Optional. Minimum and maximum aspect ratio of every item. Works when preserveAspectRatio is set to false. | | gap | number | Optional. Gap between rows and columns. | | preserveAspectRatio | boolean | Optional. By default it's false. If set to true, rowHeightRange and itemRatioRange will be ignored. | | maxColumns | number | Optional. Max columns (items) in the row. | | scrollRef | React.RefObject | Optional. A reference to the scroll element for implementing infinite scrolling, enhancing performance. | | keyExtractor | (item: SizeType, index: number) => string | number | Optional. Key extractor for better performance. |

itemRenderer props:

| Prop | Type | Description | | :------------------- | :------- | :------------------------------------------------------------------------------------------------------------------- | | item | SizeType | The original item. | | size | SizeType | The rendering size of the item. | | index | number | The index of the item in the original array. | | cropBox | BoxType | Helper field to fill the image size. Analogous to the 'object-fit: cover' CSS property for the tag. | | fitBox | BoxType | Helper field to fit the image into the size. Analogous to the 'object-fit: contain' CSS property for the tag. | | aspectRatioPreserved | boolean | Indicates whether the aspect ratio was preserved or not. |
