How do I specify a route on the root?

[mozfet]

Hi. Just started using this package today.

I need a link url for sharing with external users. The link url needs to be as short as possible.

How do I register a route without a section, for example this url?

test.com/id=1234

I tried, without success:

Router.register({
  '': async parameters => {
    console.log('Viewing root:', parameters)
  }
})

and

Router.register({
  '/': async parameters => {
    console.log('Viewing root:', parameters)
  }
})
