Can I conditionally add a where() clause to my knex query?

Question

I want to add a where() clause in my query, but conditionally. Specifically, I want it added only if a sepecific querystring parameter is passe

Answer 1

You can actually use query builder inside .where() like so:

.where((qb) => {condition == true ? do something if true : do something if false })

IMO @ItaiNoam answer should be correct with .modify()
