validator.js is a string validation and sanitization library for JavaScript.
The library addresses the need to validate and clean string input across web applications and Node.js environments. It provides a collection of functions that check whether strings match expected formats or patterns, and separate functions that transform strings by removing or escaping potentially harmful content. The approach is straightforward: developers call specific validator or sanitizer functions on input strings, passing options where needed, to determine validity or produce cleaned output.
The tool suits projects that need to validate common string formats like email addresses, URLs, IP addresses, and credit card numbers without building custom regex patterns or validation logic. It works well in both browser and server-side JavaScript contexts. The library is particularly useful when you want to avoid the complexity of larger validation frameworks while still covering standard validation scenarios.
The project shows consistent maintenance with regular updates addressing bug reports and feature requests. Pull requests receive timely review and feedback from maintainers. The codebase demonstrates active engagement with contributors, including responses to issues and incorporation of community-submitted improvements. Development activity reflects an established project that continues to evolve based on user needs rather than following a predetermined roadmap.
