Virtualized by Default Multiple Layouts Masonry Layout Lightweight

Features

• Generate grids easily.
• Build beautiful Masonry grids using the Masonry component
• Render images horizontally or vertically in a grid.
• Built-in virtualization for improved performance.
• Load 1000's of images without worrying about performance.
• UI controls for adjusting image sizes.
• Resizable Grid
• Lightweight (7kb gzipped)
• Built with typescript.
• Intuitive API.

How it works

react-visual-grid works with the absolute minimum of properties to determine the optimal method to render images. Specify the desired picture sizes and the layout, the component will automatically determine the optimum approach to rendering the images.

Comes with two different layouts (horizontal and vertical) for rendering images. The in-built virtualization ensures that the component renders only the images that are visible on the screen. This ensures that the component is able to render thousands of images without any performance issues.

Resize the grid or go full screen, and the component will automatically adjust the ideal number of images to be displayed in the new grid size.

In addition to the traditional grid, the library also comes with a masonry layout. The masonry layout is used to display images in a grid with varying heights/widths.

Installation

You can install react-visual-grid using npm or yarn.

  npm install react-visual-grid

  yarn add react-visual-grid

Usage

Grids can be generated in two modes: Horizontal and Vertical. The default mode is vertical

import { Grid } from "react-visual-grid";

// generate random images using lorem picsum service
const images = Array.from({ length: 50 }, (_, i) => ({
  src: `https://picsum.photos/id/${Math.round(Math.random() * 110)}/800/600`,
  alt: `Image ${i + 1}`,
}));

const App = () => {
  return <Grid images={images} width={1800} height={1200} />;
};

The dimensions of the grid can be also specified as percentages.

import { Grid } from "react-visual-grid";

const App = () => {
  return <Grid images={images} width="90%" height="80%" />;
};

Props

Name	Description	Type	Default
enableResize	Allows the grid to be freely resized	boolean	true
enableDarkMode	Displays a toggle switch for switching between dark mode and default mode	boolean	false
gap	Gap in pixels between the images	number	20
gridLayout	Sets up the layout of the grid. can be horizontal or vertical	string	vertical
height	Height of the Grid	number or string	600
imageSizes	Configures the zoom sizes of the Images	Object	read more
images	Collection of Images to be rendered	ImageProps	[]

Demo 1 (Horizontal)

import { Grid } from "react-visual-grid";

const App = () => {
  return (
    <Grid images={images} gridLayout="horizontal" width={1800} height={1200} />
  );
};

Horizontal Grid rendering 1k+ images

Demo 2 (Vertical)

import { Grid } from "react-visual-grid";

const App = () => {
  return (
    <Grid images={images} gridLayout="vertical" width={1800} height={1200} />
  );
};

Vertical Grid rendering 1k+ images

ImageProps

Name	Description	Type	Default
src	URL of the image	string
alt	Alt text for the image	string
width	Width of the image	number	100
height	Height of the image	number	100
id	Unique of the image	string
onClick	callback to be executed on click	Function

ImageSizes

react-visual-grid currently supports 3 zoom levels and the default level is 2x. The zoom levels can be configured using the imageSizes prop.

The component comes with a default configuration for the image sizes.

export const defaultImageSizes = {
  "1X": {
    width: 120,
    height: 100,
  },
  "2X": {
    width: 200,
    height: 180,
  },
  "3X": {
    width: 320,
    height: 280,
  },
};

you should be able to easily customize the desired dimensions for each zoom level.

Theme

Customize the colors of the component with the theme prop.

Here is the list of all the colors that can be customized:

Name	Description	Type	Default
primaryColor	Primary color of the gallery	string	#007fff
backgroundColor	Background color of the gallery	string	#000
controlBgColor	Background color of the control strip	string	#303030
controlBtnColor	Button color of the controls	string	#595959
controlsBackDropColor	Backdrop color of the controls	string	rgba(0, 0, 0, 0.95)
thumbnailBgColor	Background color of the Thumbnails	string	#202020

<Grid
  gridLayout="vertical"
  theme={{
    backgroundColor: "#000",
    controlBgColor: "#303030",
    controlBtnColor: "#595959",
    controlsBackDropColor: "rgba(0, 0, 0, 0.95)",
    thumbnailBgColor: "#202020",
  }}
/>

Custom Theme

Masonry

The masonry layout is a great choice for displaying images of different sizes. You can choose to fill the images horizontally or vertically, and choose how big you want them to be. The Masonry component sets the height and width of each image using class names. Class names should be formatted rc-w-[width], where [width] corresponds to an integer length value measured in pixels; similarly, class names should be formatted rc-h-[height], with correspondingly formatted values.

The layout honors the dimensions of the parent container, and the images will be automatically wrapped to the next row or column depending on the fill mode. In vertical fill mode, the images are arranged in columns, and in horizontal fill mode, the images are arranged in rows.

The Masonry Component exports as its own React Component, with documentation available at the following URL

<Masonry fillMode="HORIZONTAL" height={1200} width={300}>
  <span className={`rc-w-100 rc-h-100`}>
    <img alt="Image 1" src={`https://picsum.photos/id/10/100/100`} />
  </span>
  <span className={`rc-w-200 rc-h-100`}>
    <img alt="Image 1" src={`https://picsum.photos/id/11/100/100`} />
  </span>
  <span className={`rc-w-200 rc-h-100`}>
    <img alt="Image 1" src={`https://picsum.photos/id/13/200/100`} />
  </span>
  <span className={`rc-w-100 rc-h-100`}>
    <img alt="Image 1" src={`https://picsum.photos/id/14/100/100`} />
  </span>
  <span className={`rc-w-300 rc-h-150`}>
    <img alt="Image 1" src={`https://picsum.photos/id/15/200/100`} />
  </span>
</Masonry>
