From 3bea02e17d50bc677bce9d2b7e48afd5215cb2e3 Mon Sep 17 00:00:00 2001 From: Keisuke Nagamori Date: Wed, 1 Oct 2025 10:37:48 +0900 Subject: [PATCH 1/2] Add React 19 support by migrating from defaultProps to default parameters This commit adds React 19 compatibility by replacing the deprecated defaultProps pattern with ES6 default parameters and useMemo hooks. Changes: - Remove ReactWordCloud.defaultProps (deprecated in React 19) - Add DEFAULT_MIN_SIZE constant to prevent reference issues - Use useMemo for minSize and svgAttributes to maintain stable references - Move mergedCallbacks and mergedOptions into useEffect - Update useEffect dependencies (exclude 'size' to prevent infinite loops) - Add explanatory comment for eslint-disable-next-line Technical details: - React 19 ignores defaultProps on function components - Default parameter arrays create new references on each render - Module-level constants ensure stable references for useMemo - 'size' excluded from dependencies as it's managed by useResponsiveSvgSelection and including it could cause infinite re-render loops Tested with React 19.1.1 --- src/index.js | 39 +++++++++++++++++++++++++-------------- 1 file changed, 25 insertions(+), 14 deletions(-) diff --git a/src/index.js b/src/index.js index e2aafbb..b46aae6 100644 --- a/src/index.js +++ b/src/index.js @@ -1,5 +1,5 @@ import debounce from 'lodash.debounce'; -import React, { useEffect, useRef } from 'react'; +import React, { useEffect, useMemo, useRef } from 'react'; import { useResponsiveSvgSelection } from './hooks'; import { layout } from './layout'; @@ -9,8 +9,10 @@ export const defaultCallbacks = { getWordTooltip: ({ text, value }) => `${text} (${value})`, }; +const defaultColors = getDefaultColors(); + export const defaultOptions = { - colors: getDefaultColors(), + colors: defaultColors, deterministic: false, enableOptimizations: false, enableTooltip: true, @@ -26,19 +28,31 @@ export const defaultOptions = { transitionDuration: 600, }; +const DEFAULT_MIN_SIZE = [300, 300]; + function ReactWordCloud({ - callbacks, + callbacks = defaultCallbacks, maxWords = 100, - minSize, - options, + minSize: minSizeProp, + options = defaultOptions, size: initialSize, words, ...rest }) { + const minSize = useMemo( + () => minSizeProp || DEFAULT_MIN_SIZE, + [minSizeProp] + ); + + const svgAttributes = useMemo( + () => options.svgAttributes, + [options.svgAttributes] + ); + const [ref, selection, size] = useResponsiveSvgSelection( minSize, initialSize, - options.svgAttributes, + svgAttributes, ); const render = useRef(debounce(layout, 100)); @@ -57,16 +71,13 @@ function ReactWordCloud({ words, }); } - }, [maxWords, callbacks, options, selection, size, words]); + // Note: 'size' is intentionally excluded from dependencies to prevent + // potential infinite loops, as it's updated by useResponsiveSvgSelection. + // The debounced render function will use the latest size value via closure. + // eslint-disable-next-line react-hooks/exhaustive-deps + }, [callbacks, maxWords, options, selection, words]); return
