React-Text-Highlighter

Simple High Order Component that allows you to highlight your text based on text matches.

Why?

I needed a simple highlighter that works with React 0.14 and multiple non-connected words.

How to use?

npm install react-text-highlighter;

Create a component and wrap it in Highlighter.

Quick example using a stateless component:

import Highlighter from 'react-text-highlighter';
...
 
const MyComponent = ({highlightedText}) =>
<div id="result" dangerouslySetInnerHTML={{__html: highlightedText}}/>;
 
//!important
export default Highlighter(MyComponent);

Now you can cleanly add it like:

<HighLighter highlight={"Foo"} text={"Foo bar baz"} options={opts} />

Check the example dir for a simple example. You can run the example with: npm run example

Options

You need to pass an option object with the following properties:

{
  caseSensitive: true //true or false
  highlightClass: 'highlighted-text' // className for your highlighted text
}

dangerouslySetInnerHTML?

The component returns a HTML string which you need to set with dangerouslysetInnerHTML, otherwise highlighting highlighting multiple words becomes very complex. If you don't trust the source of your highlighted text. Use a library like DOMPurify. This allows you to:

import DOMPurify from 'dompurify';
...
 
<div dangerouslySetInnerHTML={ {__html: DOMPurify.sanitize(highlightedText)} }/>
