PCRE to JavaScript RegExp Converter

pcre-to-regexp is a utility library designed to convert Perl Compatible Regular Expression (PCRE) strings into native JavaScript RegExp instances. It supports parsing PCRE patterns, including handling delimiters and flags, and can extract named capture group keys. The current stable version is 1.1.0. The project maintains a somewhat irregular release cadence, with the last major update (v1.0.0) occurring relatively recently, primarily focusing on a refactor to TypeScript for improved type safety and maintainability. Its key differentiator lies in its specialized focus on PCRE conversion, which is useful for migrating regular expressions from environments like PHP (which heavily uses PCRE) to JavaScript, although it notes it's not yet feature-complete for all PCRE constructs.
