masonry-gridify v1.0.3

Masonry React Component

A lightweight, responsive, and customizable Masonry grid component for React.

Features

• Auto-calculates columns based on container width.
• Resizes dynamically when the window size changes.
• Provides smooth transitions.
• Uses ResizeObserver for real-time adjustments.

Installation

npm install masonry-gridify
// or
npm install --save masonry-gridify
// or
yarn add masonry-gridify

Usage

If height is not defined

It takes the clientHeight of each element even if height is defined or not. So no need to explicitly define the height.

If height is defined

import Masonry from "masonry-gridify";

const Example = () => {
  return (
    <Masonry gap={10} width={"250px"}>
      <div style={{ height: "150px", background: "red" }}></div>
      <div style={{ height: "200px", background: "blue" }}></div>
      <div style={{ height: "250px", background: "green" }}></div>
      <div style={{ height: "180px", background: "yellow" }}></div>
    </Masonry>
  );
};

export default Example;

Props

How It Works

1. Dynamic Column Calculation:

   • Calculates columns based on container width and column width.
   • Uses ResizeObserver and window resize events for responsiveness.

2. Element Positioning:

   • Uses CSS transforms to adjust element positions.
   • Maintains vertical gaps between items.
   • Handles overlapping elements through margin adjustments.

3. Performance:

   • Debounced resize handling (200ms delay).
   • RequestAnimationFrame for smooth transitions.
   • Cleanup of observers and event listeners.

Debugging Guide

Common Issues & Fixes

1. No items appear

   • Ensure children are passed correctly.
   • Check for missing gap or width props.

2. Elements are overlapping or positioned incorrectly

   • Try refreshing the page. If the issue persists, inspect the elements in DevTools.

3. Layout Not Updating on Resize

   • Check if the ResizeObserver is working in your browser’s dev tools.
   • Try forcing an update by changing the window size.

4. Flickering During Transitions

   Copy paste this code in your item. If the issue persists, you can always create a pull request.

   // Add this to your masonry items' CSS:
   .masonryItem {
     will-change: transform;
     backface-visibility: hidden;
   }
