## What it is
A TypeScript utility library that automatically converts URLs, email addresses, phone numbers, @mentions, and #hashtags in plain text or HTML into clickable anchor links. It handles HTML input safely without corrupting existing tags and runs in linear time without ReDoS vulnerability.

## Use cases
- autolink urls in user comments
- convert plain text emails and phone numbers into clickable links
- linkify hashtags and mentions in a social feed
- safely autolink text that contains existing HTML
- detect and link urls without protocol prefix like google.com
- prevent ReDoS when linkifying untrusted user input

## When to choose
- you need robust, fast, HTML-safe autolinking of mixed entity types (URLs, emails, phones, mentions, hashtags)
- you are processing untrusted input and need ReDoS-safe linear-time matching
- you need to avoid double-linking text inside existing anchor tags

## When to avoid
- you only need simple URL detection with no HTML handling and want a minimal dependency
- you need entity extraction with structured output rather than HTML anchor generation
- you need markdown-aware link processing

## Facets
- artifact type: library
- maturity: stable
- function: parser, nlp, developer-tools
- domain: web-development, text-editors
- platform: browser, cross-platform
- tags: autolinking, url-detection, hashtags, mentions, phone-numbers, email-detection, html-safe, redos-safe, natural-language-processing, nodejs, typescript
