const P = require('js-parser-combinators')

// A parser that can parse paths such as:

//    /user/1234

//    /user/1234/details

const parser = P.exhaustive(

    P.and(

        P.and(

            P.literal('/user/'),

            P.param('userid', /^\d+/, parseInt)

        ),

        P.optional(P.literal('/details'))

    )

);

parser({ input: '/user/1234/details' }).ast

// => { userid: 1234 }
