Release Notes

STRML/react-grid-layout (react-grid-layout)

v2.2.2

Compare Source

🧪 Tests

• prevent infinite loop when dragging external items in controlled state (#​2210) - #​2225 by @​STRML

🔧 Internal Changes

• prevent infinite loop when dragging external items in controlled state (#​2210) - #​2225 by @​STRML

v2.2.1

Compare Source

Bug Fixes

• Drag position: Fix items jumping half a screen down when drag starts on a grid container offset from the page top. Removed calcDragPosition from default position strategies since react-draggable handles parent-relative coordinates correctly. #​2223
• Compactor: Ensure all internal v2 code uses compactor.compact() instead of the legacy compact() function. Added optional compactor prop to hooks (useGridLayout, useResponsiveLayout) that takes precedence over compactType/allowOverlap. Fixed negative coordinate handling in compactors. #​2222, fixes #​2213
• Drag-from-outside: Add defensive guards for edge cases with drag enter/leave counter synchronization. Made removeDroppingPlaceholder idempotent and prevented negative counter values. #​2220, fixes #​2210

Internal Changes

• Removed never-exported compat layers (utils-compat.ts, responsive-compat.ts, calculate-compat.ts). These were internal implementation details and were never part of the public API.
• Removed onMove() method from Compactor interface. Custom compactors should implement only compact().

v2.2.0

Compare Source

Bug Fixes

• GridItem: Fix infinite loop when dragging from outside then leaving the grid without releasing the mouse. Applied the same layoutRef pattern from GridLayout to GridItem's constraint context. #​2214, fixes #​2210
• DropConfig: Fix dropConfig.onDragOver being ignored. The v2 API's onDragOver callback is now properly called when provided. #​2215, fixes #​2212
• Compactor: Fix custom compactor's compact() method never being called. GridLayout was extracting properties but ignoring the method implementations. #​2216, fixes #​2213
• PositionStrategy: Fix custom calcStyle() and calcDragPosition() methods never being called. Custom position strategies can now fully override positioning behavior. #​2217
• DragConfig: Implement threshold property (default 3px for v2 API). Drag callbacks now wait until mouse moves the threshold distance before firing, preventing accidental drags on click. Legacy API uses threshold=0 for backwards compatibility. #​2217, fixes #​1341, #​1401

v2.1.1

Compare Source

Bug Fixes

• Legacy API: Fix allowOverlap not working in legacy mode. Added noOverlapCompactor for when compactType=null and allowOverlap=true. #​2207
• GridLayout: Fix "Maximum update depth exceeded" during drag/resize/drop operations. Used layoutRef pattern to prevent callbacks from being recreated on every layout change. #​2208
• useResponsiveLayout: Fix infinite re-render loop when passing inline objects as layouts prop. Added separate ref to track props vs state changes. #​2209

New Features

Pluggable Layout Constraints System

A new constraints system allows custom validation and transformation of layout items during drag and resize operations. #​2190

import { createConstraintEnforcer, aspectRatioConstraint, positionConstraint } from "react-grid-layout/core";

const enforcer = createConstraintEnforcer([
  aspectRatioConstraint(16 / 9),
  positionConstraint({ minX: 0, maxX: 10 })
]);

<GridLayout constraintEnforcer={enforcer} />

Fast Compactors for Large Layouts

New O(n log n) compactors in react-grid-layout/extras for layouts with 200+ items:

• fastVerticalCompactor - Up to 45x faster than standard vertical compaction. #​2184
• fastHorizontalCompactor - Up to 74x faster than standard horizontal compaction. #​2189, #​2193

import { fastVerticalCompactor, fastHorizontalCompactor } from "react-grid-layout/extras";

<GridLayout compactor={fastVerticalCompactor} />

Wrap Compactor

New wrapCompactor for paragraph-style layouts where items flow left-to-right and wrap to the next row. #​2186

import { wrapCompactor } from "react-grid-layout/extras";

<GridLayout compactor={wrapCompactor} />

Improved Examples

• Added navigable sidebar to examples for easier exploration
• New grid matrix panel for visualizing layout state. #​2197

Bug Fixes

• WidthProvider: Re-observe element after measureBeforeMount switches from placeholder. #​2198
• Drop positioning: Center dropped items on cursor position instead of top-left corner. #​2196
• Margin calculation: Ensure consistent margins between grid items. #​2195
• Compaction: Disable early break optimization when static items are present, fixing incorrect layouts. #​2194
• Responsive layouts: Prevent infinite layout oscillation in toolbox pattern. #​2192
• CSS: Remove user-select: none from grid items to restore auto-scroll behavior. #​2188

Tests

• Added maxRows enforcement tests for calcXY and calcWH. #​2185

Internal Changes

• Improved changelog action for better automated release notes. #​2199

v2.0.0

Compare Source

Version 2 is a complete TypeScript rewrite with a modernized hooks-based API. See the RFC for the full design document.

Highlights

• Full TypeScript support - First-class types, no more @types/react-grid-layout needed
• React Hooks API - New useContainerWidth, useGridLayout, and useResponsiveLayout hooks
• Composable Configuration - Group related props into focused interfaces (gridConfig, dragConfig, resizeConfig, positionStrategy, compactor)
• Modular Architecture - Tree-shakeable ESM and CJS builds with multiple entry points
• Legacy Compatibility - 100% backwards compatible via react-grid-layout/legacy

Breaking Changes

See the migration section in the README for detailed examples.

width Prop Required

The grid no longer auto-measures width. Use the new useContainerWidth hook:

import ReactGridLayout, { useContainerWidth } from "react-grid-layout";

function MyGrid() {
  const { width, containerRef, mounted } = useContainerWidth();
  return (
    <div ref={containerRef}>
      {mounted && <ReactGridLayout width={width} ... />}
    </div>
  );
}

Or use the legacy wrapper for backwards compatibility:

import ReactGridLayout, { WidthProvider } from "react-grid-layout/legacy";
const GridLayoutWithWidth = WidthProvider(ReactGridLayout);

onDragStart Threshold

onDragStart now fires after 3px of mouse movement, not on mousedown. This fixes #​1341 and #​1401. Use onMouseDown directly on grid items if you need immediate response.

Immutable Callback Parameters

Callback parameters (layoutItem, placeholder) are now read-only. Mutating them in onResize/onDrag callbacks no longer works. Use onLayoutChange or item constraints (minW, maxW, etc.) instead.

data-grid Prop in Legacy Only

The v2 API requires explicit layout prop. The data-grid pattern is only available via the legacy wrapper (react-grid-layout/legacy).

Pluggable Compaction Algorithms

Compaction is now pluggable via the Compactor interface. The default compaction algorithm remains the same as v1 for backwards compatibility. For large layouts (200+ items), an optional O(n log n) fast compactor is available in react-grid-layout/extras:

import { fastVerticalCompactor } from 'react-grid-layout/extras';
<GridLayout compactor={fastVerticalCompactor} />

Other Breaking Changes

• UMD bundle removed - Use a bundler (Vite, webpack, esbuild)
• verticalCompact prop removed - Use compactType={null} or compactor={noCompactor}
• React 18+ required - React 16/17 support is available only via the legacy wrapper

New Features

Entry Points

// v2 API (recommended)
import ReactGridLayout, {
  Responsive,
  useContainerWidth
} from "react-grid-layout";

// Core utilities (framework-agnostic, no React)
import { compact, moveElement, collides } from "react-grid-layout/core";

// Legacy v1 API (100% backwards compatible)
import ReactGridLayout, {
  WidthProvider,
  Responsive
} from "react-grid-layout/legacy";

// Optional extras
import { GridBackground } from "react-grid-layout/extras";

Hooks

• useContainerWidth() - Reactive container width measurement with ResizeObserver
• useGridLayout() - Core layout state management for custom implementations
• useResponsiveLayout() - Responsive breakpoint management

Composable Configuration Interfaces

<ReactGridLayout
  width={width}
  layout={layout}
  gridConfig={{ cols: 12, rowHeight: 30, margin: [10, 10] }}
  dragConfig={{ enabled: true, handle: ".handle", bounded: true }}
  resizeConfig={{ enabled: true, handles: ["se", "sw"] }}
  positionStrategy={transformStrategy}
  compactor={verticalCompactor}
/>

Pluggable Compactors

Create custom compaction algorithms by implementing the Compactor interface:

import {
  verticalCompactor,
  horizontalCompactor,
  noCompactor
} from "react-grid-layout/core";

// Or create custom compactors
const myCompactor: Compactor = {
  type: "custom",
  allowOverlap: false,
  compact(layout, cols) {
    /* ... */
  },
  onMove(layout, item, x, y, cols) {
    /* ... */
  }
};

Position Strategies

Control CSS positioning with the PositionStrategy interface:

import { transformStrategy, absoluteStrategy, createScaledStrategy } from "react-grid-layout/core";

// For scaled containers
<div style={{ transform: "scale(0.5)" }}>
  <ReactGridLayout positionStrategy={createScaledStrategy(0.5)} />
</div>

GridBackground Component

New optional component to visualize the grid structure:

import { GridBackground } from "react-grid-layout/extras";

<GridBackground
  width={width}
  cols={12}
  rowHeight={30}
  rows={10}
  color="#f0f0f0"
/>;

Core Utilities

New calcGridCellDimensions utility for building custom grid overlays:

import { calcGridCellDimensions } from "react-grid-layout/core";

const dims = calcGridCellDimensions({
  width: 1200,
  cols: 12,
  rowHeight: 30,
  margin: [10, 10]
});
// { cellWidth, cellHeight, offsetX, offsetY, gapX, gapY, cols, containerWidth }

React 18 Compatibility

• Full React 18 support. The library now works seamlessly with React 18's automatic batching without any flushSync warnings.
• Removed flushSync usage from drag and resize handlers.

Bugfixes

• Fixed operator precedence bug in moveDroppingItem where shouldDrag would incorrectly evaluate to true when only the top position changed.
• Fixed resize position calculation when node is falsy in onResizeHandler.

Internal Changes

• Complete TypeScript rewrite - All code is now TypeScript with full type coverage
• Migrated from Flow to TypeScript - Removed all Flow annotations
• Modular package structure - src/core/ (pure TS), src/react/ (React bindings), src/legacy/ (v1 compatibility)
• Build system - Now uses tsup for ESM, CJS, and declaration file generation
• Migrated test suite from Enzyme to React Testing Library
• ESLint 9 with flat config
• Removed lib/ folder and Flow configuration
• Removed snapshot tests in favor of behavioral tests

Migration Guide

Quick migration (no code changes):

- import GridLayout from 'react-grid-layout';
+ import GridLayout from 'react-grid-layout/legacy';

Full migration (recommended for new features):

1. Replace WidthProvider HOC with useContainerWidth hook
2. Replace data-grid props with explicit layout prop
3. Use configuration interfaces (gridConfig, dragConfig, etc.) for cleaner props
4. Update any code that mutates callback parameters to use onLayoutChange instead
