LinkLens is a lightweight **React npm package** that automatically detects URLs in any text (comments, chat messages, posts) and highlights them. You can also enable **rich link previews** with thumbnails, titles, and descriptions — similar to how social media platforms preview links.


## Installation

```sh
npm install linklens --force
```


## Features

- Detects and highlights URLs, hyperlinks, mentions (@username), and hashtags (#topic) in text (React link highlighter, URL parser)
- Generates rich link previews with thumbnails, titles, and descriptions (React social media preview)
- Supports hover previews and clickable links (React interactive link component)
- Custom regex support for matching patterns like hashtags, mentions, or custom keywords (React text parser)
- Lightweight and optimized for React 18+ projects (npm package, zero dependencies)
- Fully customizable link colors, HTML tags, and container styles (React component styling)
- Works with chat messages, comments, posts, blogs, and forums (React chat app, comment system)
- Easy integration into React projects with minimal setup (npm React library, link detection)
- Supports accessibility-friendly links and previews (React ARIA support, screen reader friendly)
