Pull URL's referral info with NextJS

Question

I'm trying to create a referral system for an app by adding a referral link defined as:

const link = `${global.origin}?ref=${address}`;

which returns something like http://localhost:3000/?ref='address'

I'm struggling to find a way to get Nextjs to pull just the 'address' part of the url (and define it to be used in a function).

Answer 1

If I get it right you can use router.query["ref"] from Next router.
