Age Gate middleware for Express.js


  • Moment.js
  • Express.js
  • body-parser
  • cookie-parser


This middleware allows you to age gate your site to limit access. With this middleware you can customize what your age gate url is (default is /agegate) and the minimum age required to access your site (default is 21).

Options are sent to the middleware as a JSON object like


This middleware is also setup to look for common search engine robots and allow them to bypass the age gate so they may index your site.

To allow users to pass the age gate, your site must have a form that POSTs to the age gate url an input named - 'birthdate'. So for example if your age gate url is /agegate - that page should have at least the following form -

    <form method="post">
        <input type="text" name="birthdate"/>
        <input type="submit" val="submit"/>

When posting back to the age gate url - the birthdate field simply needs to be in any date format that moment.js can parse. For information about moment.js please checkout -
