How to pass and use a URL parameters in the root/entry page

# Use case:

The link to the candidate's resume will have this format: https://resumeapp.heroku.com/?email=myemail@email.com

The end-user should be able to see the candidate's resume from the entry/root page.

The email parameter should be used to filter the soql query in the src/server/api.js

# What I tried

I tried to set the route to the root endpoint in both api.js and candidateService.js, but the page shows no details about the record.
