safe-regex safeguards your Node.js applications against ReDoS (Regular Expression Denial of Service) attacks. It analyzes regular expressions for vulnerability to excessive backtracking, preventing potential slowdowns or crashes. By identifying regex patterns that could take exponentially longer to process based on input, safe-regex helps developers write more robust and secure code, ensuring application stability. It offers a crucial defense against exploits that leverage inefficient regular expressions.
