express-bakery

Set cookies via query parameters.

• Convenient -- no mucking around with cookie extensions, just write a url!
• Simple -- no explaining to non-technical users how to install an extension and set a cookie, just send them a url like http://example.com?bake:in_experiment:true and once they visit it, they've got the cookie!

Installation

$ npm install --save express-bakery
# or
$ yarn add express-bakery
