Does Nextjs make you use Django less? I think my basic process going forward is going to be Nextjs + something like Supabase as default and only add a more complex backend as needed.
At work we don't have enough manpower*time to convert our React spaghettis to Next.js, but I'm starting to experiment with Next.js & prisma & postgres aside and plan to use it for my next hobby project which I'm never gonna finish just as the rest of them..., If I'm gonna like the approach and not miss some of Django's features right from the start I'm gonna think about letting Django in the past...
Supabase could be enough for a simpler project where you know you won't need any advanced features.., I wouldn't just start with it if I knew the project's gonna get huge in the future, but I did a couple of smaller projects with Firebase alone..
