# react-d3-cloud
[](https://badge.fury.io/js/react-d3-cloud)
[](https://github.com/Yoctol/react-d3-cloud/actions?query=branch%3Amaster)
A word cloud react component built with [d3-cloud](https://github.com/jasondavies/d3-cloud).
## Installation
```sh
npm install react-d3-cloud
```
## Usage
Simple:
```jsx
import React from 'react';
import { render } from 'react-dom';
import WordCloud from 'react-d3-cloud';
const data = [
{ text: 'Hey', value: 1000 },
{ text: 'lol', value: 200 },
{ text: 'first impression', value: 800 },
{ text: 'very cool', value: 1000000 },
{ text: 'duck', value: 10 },
];
render(, document.getElementById('root'));
```
More configuration:
```jsx
import React from 'react';
import { render } from 'react-dom';
import WordCloud from 'react-d3-cloud';
import { scaleOrdinal } from 'd3-scale';
import { schemeCategory10 } from 'd3-scale-chromatic';
const data = [
{ text: 'Hey', value: 1000 },
{ text: 'lol', value: 200 },
{ text: 'first impression', value: 800 },
{ text: 'very cool', value: 1000000 },
{ text: 'duck', value: 10 },
];
const schemeCategory10ScaleOrdinal = scaleOrdinal(schemeCategory10);
render(
Math.log2(word.value) * 5}
spiral="rectangular"
rotate={(word) => word.value % 360}
padding={5}
random={Math.random}
fill={(d, i) => schemeCategory10ScaleOrdinal(i)}
onWordClick={(event, d) => {
console.log(`onWordClick: ${d.text}`);
}}
onWordMouseOver={(event, d) => {
console.log(`onWordMouseOver: ${d.text}`);
}}
onWordMouseOut={(event, d) => {
console.log(`onWordMouseOut: ${d.text}`);
}}
/>,
document.getElementById('root')
);
```

for more detailed props, please refer to below:
## Props
| name | description | type | required | default |
| --------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | -------------------------------------------------------------------- | -------- | ------------------------------------------- |
| data | The words array | `{ text: string, value: number }>[]` | ✓ |
| width | Width of the layout (px) | `number` | | `700` |
| height | Height of the layout (px) | `number` | | `600` |
| font | The font accessor function, which indicates the font face for each word. A constant may be specified instead of a function. | `string \| (d) => string` | | `'serif'` |
| fontStyle | The fontStyle accessor function, which indicates the font style for each word. A constant may be specified instead of a function. | `string \| (d) => string` | | `'normal'` |
| fontWeight | The fontWeight accessor function, which indicates the font weight for each word. A constant may be specified instead of a function. | `string \| number \| (d) => string \| number` | | `'normal'` |
| fontSize | The fontSize accessor function, which indicates the numerical font size for each word. | `(d) => number` | | `(d) => Math.sqrt(d.value)` |
| rotate | The rotate accessor function, which indicates the rotation angle (in degrees) for each word. | `(d) => number` | | `() => (~~(Math.random() * 6) - 3) * 30` |
| spiral | The current type of spiral used for positioning words. This can either be one of the two built-in spirals, "archimedean" and "rectangular", or an arbitrary spiral generator can be used | `'archimedean' \| 'rectangular' \| ([width, height]) => t => [x, y]` | | `'archimedean'` |
| padding | The padding accessor function, which indicates the numerical padding for each word. | `number \| (d) => number` | | `1` |
| random | The internal random number generator, used for selecting the initial position of each word, and the clockwise/counterclockwise direction of the spiral for each word. This should return a number in the range `[0, 1)`. | `(d) => number` | | `Math.random` |
| fill | The fill accessor function, which indicates the color for each word. | `(d, i) => string` | | `(d, i) => schemeCategory10ScaleOrdinal(i)` |
| onWordClick | The function will be called when `click` event is triggered on a word | `(event, d) => {}` | | null |
| onWordMouseOver | The function will be called when `mouseover` event is triggered on a word | `(event, d) => {}` | | null |
| onWordMouseOut | The function will be called when `mouseout` event is triggered on a word | `(event, d) => {}` | | null |
## FAQ
### How to Use with Next.js/SSR
To make `` work with Server-Side Rendering (SSR), you need to avoid rendering it on the server:
```js
{
typeof window !== 'undefined' && ;
}
```
### How to Avoid Unnecessary Re-render
As of version 0.10.1, `` has been wrapped by `React.memo()` and deep equal comparison under the hood to avoid unnecessary re-render. All you need to do is to make your function props deep equal comparable using `useCallback()`:
```js
import React, { useCallback } from 'react';
import { render } from 'react-dom';
import WordCloud from 'react-d3-cloud';
import { scaleOrdinal } from 'd3-scale';
import { schemeCategory10 } from 'd3-scale-chromatic';
function App() {
const data = [
{ text: 'Hey', value: 1000 },
{ text: 'lol', value: 200 },
{ text: 'first impression', value: 800 },
{ text: 'very cool', value: 1000000 },
{ text: 'duck', value: 10 },
];
const fontSize = useCallback((word) => Math.log2(word.value) * 5, []);
const rotate = useCallback((word) => word.value % 360, []);
const fill = useCallback((d, i) => scaleOrdinal(schemeCategory10)(i), []);
const onWordClick = useCallback((word) => {
console.log(`onWordClick: ${word}`);
}, []);
const onWordMouseOver = useCallback((word) => {
console.log(`onWordMouseOver: ${word}`);
}, []);
const onWordMouseOut = useCallback((word) => {
console.log(`onWordMouseOut: ${word}`);
}, []);
return (
);
);
```
