node-re2
Node.js bindings for Google's RE2 regex engine, providing a fast and safe alternative to backtracking regex engines.
What is node-re2?
node-re2 is a Node.js binding for Google's RE2 regular expression engine, providing a safe and performant alternative to JavaScript's built-in RegExp. It protects against Regular Expression Denial of Service (ReDoS) attacks by using deterministic finite automata instead of backtracking evaluation.
Node.js developers processing untrusted user input, building security-sensitive applications, or working with performance-critical regex operations on large datasets.
Developers choose node-re2 for its guaranteed linear-time matching that prevents ReDoS vulnerabilities while maintaining high compatibility with the standard RegExp API, plus additional features like Buffer support and multi-pattern matching.
