Psl is a JavaScript domain name parser based on the Public Suffix List (https://publicsuffix.org/). This implementation is tested against the test data hosted by Mozilla and kindly provided by Comodo.

The Public Suffix List is a cross-vendor initiative to provide an accurate list of domain name suffixes. A "public suffix" is one under which Internet users can directly register names. Some examples of public suffixes are ".com", ".co.uk" and "pvt.k12.wy.us". The Public Suffix List is a list of all known public suffixes.

This package provides the node.js module.
