README
React component to highlight words within a larger body of text.
Check out a demo [here](https://bvaughn.github.io/react-highlight-words).
## Usage
To use it, just provide it with an array of search terms and a body of text to highlight.
[Try this example in Code Sandbox.](https://codesandbox.io/s/5v8yqoxv7k)
```jsx
import React from "react";
import { createRoot } from "react-dom/client";
import Highlighter from "react-highlight-words";
const root = createRoot(document.getElementById("root"));
root.render(
);
```
And the `Highlighter` will mark all occurrences of search terms within the text:
## Props
| Property | Type | Required? | Description |
|------------------------|-----------------------------|:---------:|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| `activeClassName` | String | | The class name to be applied to an active match. Use along with `activeIndex` |
| `activeIndex` | Number | | Specify the match index that should be actively highlighted. Use along with `activeClassName` |
| `activeStyle` | Object | | The inline style to be applied to an active match. Use along with `activeIndex` |
| `autoEscape` | Boolean | | Escape characters in `searchWords` which are meaningful in regular expressions |
| `className` | String | | CSS class name applied to the outer/wrapper `` |
| `caseSensitive` | Boolean | | Search should be case sensitive; defaults to `false` |
| `findChunks` | Function | | Use a custom function to search for matching chunks. This makes it possible to use arbitrary logic when looking for matches. See the default `findChunks` function in [highlight-words-core](https://github.com/bvaughn/highlight-words-core) for signature. Have a look at the [custom findChunks example](https://codesandbox.io/s/k20x3ox31o) on how to use it. |
| `highlightClassName` | String or Object | | CSS class name applied to highlighted text or object mapping search term matches to class names. |
| `highlightStyle` | Object | | Inline styles applied to highlighted text |
| `highlightTag` | Node or String | | Type of tag to wrap around highlighted matches. Defaults to `mark` but can also be a React component (class or functional) |
| `sanitize` | Function | | Process each search word and text to highlight before comparing (eg remove accents); signature `(text: string): string` |
| `searchWords` | Array | ✓ | Array of search words. String search terms are automatically cast to RegExps unless `autoEscape` is true. |
| `textToHighlight` | String | ✓ | Text to highlight matches in |
| `unhighlightClassName` | String | | CSS class name applied to unhighlighted text |
| `unhighlightStyle` | Object | | Inline styles applied to unhighlighted text |
| `unhighlightTag` | Node or String | | Type of tag applied to unhighlighted parts. Defaults to `span` but can also be a React component (class or functional) |
| * | any | | Any other props (such as `title` or `data-*`) are applied to the outer/wrapper `` |
## Custom highlight tag
By default, this component uses an HTML Mark Text element (``) to wrap matched text, but you can inject a custom
tag using the `highlightTag` property. This tag should be a React component that accepts the following properties:
| Property | Type | Description |
|------------------|--------|------------------------|
| `children` | String | Text to be highlighted |
| `highlightIndex` | Number | Index of matched text |
For example:
```js
const Highlight = ({ children, highlightIndex }) => (
{children}
);
```
## Installation
```
yarn add react-highlight-words
```
```
npm i react-highlight-words
