react-multi-highlite

react-multi-highlite is a lightweight React component that allows you to highlight specific words or phrases within a block of text. This component is very lightweight as it doesn't use highlight.js or lowlight and doesn't include bulky coding languages. It's a basic text highlighter designed to be simple and efficient.

Why 'Lite'?

react-multi-highlite is designed to be lightweight and efficient. It doesn't bring in large dependencies, making it ideal for projects where performance and bundle size are critical considerations.

pnpm

pnpm add react-multi-highlite

Usage

To use the MultiHighLite component, import it and pass the text you want to highlight along with an array of matcher objects. Each matcher object should contain the text to highlight and the class name to apply to the highlighted text.

import React from 'react';
import MultiHighLite from 'react-multi-highlite';

const App = () => {
  const text = "In software development, highlighting important pieces of information can greatly improve readability and comprehension. For instance, highlighting code snippets, errors, or important notes in documentation can make a significant difference.";
  const matchers = [
    { text: "highlighting", classname: "bg-red-200 text-black" },
    { text: "important", classname: "bg-green-300 text-black" },
    { text: "information", classname: "bg-gray-600 text-white" },
  ];

  return (
    <div>
      <MultiHighLite matchers={matchers}>{text}</MultiHighLite>
    </div>
  );
};

export default App;
