req.params

This property is an object containing properties mapped to the named route “parameters”. For example, if you have the route /user/:name, then the “name” property is available as req.params.name. This object defaults to {}.

// GET /user/tj
req.params.name
// => "tj"

When you use a regular expression for the route definition, capture groups are provided in the array using req.params[n], where n is the n^th capture group. This rule is applied to unnamed wild card matches with string routes such as /file/*:

// GET /file/javascripts/jquery.js
req.params[0]
// => "javascripts/jquery.js"
