safe-regex-test is an npm package that provides a safer alternative to JavaScript's built-in RegExp.prototype.test method. It mitigates the risk of regular expression denial-of-service (ReDoS) attacks by limiting the execution time of the regex test. If the test takes too long, it aborts and returns false, preventing potential server crashes caused by maliciously crafted regular expressions. It enhances application security and reliability when dealing with user-provided regular expressions.
