Seeding database with pnpm

I followed this tutorial and I'm using SQLite, but now when I run my Next.js app (

pnpm run dev

pnpm run dev

), a

dev.db

dev.db

file is created, but it's not seeded.
I assume it's normal for a new database to be created for each app, but how can I make sure it's seeded ?
