Can anyone point me in the direction of any SPA framework well integrated with a backend framework that can make me as productive as Django, Laravel or Rails?
I find myself very productive in it, especially compared to trying to build a highly interactive frontend on top of a Django app. The tutorial app on their website does a great job of demonstrating the capabilities of it and the patterns you'll expect to use, and you should be able to follow along in one long coding session.
It doesn't have built in auth, admin, or ORM, but it heavily advocates for the use of Prisma which is probably your best option for ORM in js. So far, no node ORM really comes close to Django's in terms of capabilities. They don't really even try on the production-ready migrations system. However, you could always use Django to get auth (change your hashing to bcrypt and get a bcrypt lib from npm) and admin for free and use `prisma db pull` to keep your Prisma schema definitions (and corresponding type modules) in sync.
That‘s the only SPA model I have seen which is a real productive approach.
That's significantly more work than just doing whatever logic you want on the server to begin with where you have access to all tables directly (they're an ORM call away) and not have to worry about access control because all of this still happens within the trusted environment of the server.
Instead of this:
def endpointAB:
a = db.getA()
b = db.getB()
return template('ab.html', {a=a, b=b})
def endpointAB:
a = db.getA()
b = db.getB()
return json({a=a, b=b})
