Regexp based validation collection for common internet validation tasks

NPM version Build Status Coverage Status Dependency Status

This is a collection of regular expressions for general validation purposes. The basic design concept is to split up the regexes into semantic parts of the pattern to match. As an example a url consists of many parts like scheme, optional userinfo, subdomain, domain, toplevel domain, path, query and fragment. It is a lot easier to write a maintainable and reusable regular expression by mathing each of these parts individually and write a regex that combines the individual later.

The library includes a TLD whitelist that can be updated using make.

This module works as a NodeJS CommonJS module, a require.js AMD module and falls back to exposing itself in the global scope on one.validation if included directly in the page.

  • npm: npm install one-validation
  • bower: bower install validation
