I'm all for a monorepo – or to a lesser degree, utility functions that are re-usable across components. That's not what I'm talking about.

Running NextJS as a handful of lambdas is fine, but you still likely need to initialize other services in the background (like databases)... otherwise you have a monolithic front-end... as in: "my monolithic front end talks to my monolithic back end, so I really have two micro/macro services", and maybe I should investigate breaking the FE/BE down into smaller components".

sure, you can use pgbouncer, etc. but it becomes sorta cost prohibitive to run a few apps.

Monolith + a database, that's always implied, isn't it?

How you make the database connection work with serverless connection requirements seems like a minor issue. I haven't used it but it seems like next + prisma (+ tailwind lol) is the default stack of tutorial writers these days.

It's really not. See... databases like PostgreSQL aren't designed for an infinite number of simultaneous connections (doing things like, checking for a logged in user, and auth). This is where something like pgbouncer comes in – that at least takes care of transaction boundaries – because we're a monolith, remember?

Now you're also setting up the state of your application as global variables. Seems like a pretty poor choice, and now you also need to figure out the gotchas with HMR here.

Let's not even get into the fact that a lot of code isn't meant to be (or cannot be) bundled by webpack. So now you're resorting to a custom Webpack config to exclude certain modules. [0]

On AWS, pgbouncer is called "RDS Proxy" and runs you $11.16/mo. [1]

That's not even getting into the cognitive overhead of just "rolling out an app over a weekend" now being a weekend adventure in and of itself – again managing an alphabet soup of services either all within AWS or between AWS and Vercel.
