JSPM – react-highlight-words@0.18.0

Package Exports

react-highlight-words
react-highlight-words/dist/main.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (react-highlight-words) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

React component to highlight words within a larger body of text.

Check out a demo here.

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.

import React from "react";
import { createRoot } from "react-dom/client";
import Highlighter from "react-highlight-words";


const root = createRoot(document.getElementById("root"));
root.render(
  <Highlighter
    highlightClassName="YourHighlightClass"
    searchWords={["and", "or", "the"]}
    autoEscape={true}
    textToHighlight="The dog is chasing the cat. Or perhaps they're just playing?"
  />
);

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 `<span>`
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 for signature. Have a look at the custom findChunks example 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		Type of tag to wrap around highlighted matches; defaults to `mark` but can also be a React element (class or functional)
sanitize	Function		Process each search word and text to highlight before comparing (eg remove accents); signature `(text: string): string`
searchWords	Array<String \| RegExp>	✓	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
*	any		Any other props (such as `title` or `data-*`) are applied to the outer/wrapper `<span>`

Custom highlight tag

By default this component uses an HTML Mark Text element (<mark>) 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:

const Highlight = ({ children, highlightIndex }) => (
  <strong className="highlighted-text">{children}</strong>
);
