Allow dynamic cookie path

[piktur]

What problem does this feature solve?

In applications employing multiple authentication strategies it should be possible to isolate cookie attributes to a path unique to each strategy.

Given two login pages /admin/login and /customer/login

When I login as admin in one tab

document.cookie 
auth.strategy=admin

and login as customer in another tab

document.cookie 
auth.strategy=customer

then return to admin tab and refresh

document.cookie 
auth.strategy=customer 

then token verification fails because the strategy was overridden when we logged in as customer.

What does the proposed changes look like?

This would cease to be a problem if it were possible to configure the cookie path per strategy or simply allow the developer to provide a function to options.cookie.options.path as in the following example.

// nuxt.config.js
auth: {
  cookie: {
    options: {
      path: () => /path/.test(window.location.pathname) ? '/path-a' : '/path-b'
    }
  }
}

// auth/storage.js
setCookie (key, value, options = {}) {
  // ...

  if (_options.path instanceof Function) {
    _options.path = _options.path()
  }

  // ...
}
