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
