cssbundling-rails VS overmind

See the issue I opened on Github. [EDIT: closed by DHH recently]

In the Procfile.dev that's currently generated by the cssbundling-rails and jsbundling-rails gems, we can see that they write the web process like:

The functionality comes from https://github.com/rails/jsbundling-rails and https://github.com/rails/cssbundling-rails -- both come with Rails 7 and all you have to do is generate your app with the choices you want such as -j esbuild --css tailwind.

TailwindCSS from CSS Bundling for Rails - (this post)

Maybe https://github.com/rails/cssbundling-rails does what you want? For CSS only, afaik it's perfectly fine to mix different approaches for CSS and JS within one Rails app, so you could still use importmaps for JS.

The docs at https://github.com/rails/cssbundling-rails clearly state that

Install cssbundling-rails gem.

Propshaft has a smaller scope than sprockets and requires you to rely on the js-bundling and css-bundling gems to handle the building of CSS and JS assets. Read the docs for an extensive upgrade guide.

As you may know there's also a [CSS bundling](https://github.com/rails/cssbundling-rails). However, I've only upgraded a trivial project, don't know how involved that would be.

Another solution is to use a different tool to drive the Procfile. The one I'm most familiar with is a tool called overmind. If you run your Procfile with overmind, you'll be able to open up a new terminal window and individually connect to any of the processes that are running. So if you want to connect to the web process to debug, you can open up a new window and run overmind connect web, and you'll have a window where you can work with the debugger's prompt.

I recently wrote about Overmind (https://github.com/DarthSim/overmind), a drop in replacement for foreman.

If you've ever used Forman or another local Procfile/process manager, I think you'll love Overmind.

It's basically a more customisable foreman that runs in tmux - which means you can do cool things like tmux into a process and attach a debugger (which is nearly impossible with foreman).

Hope you enjoy the article!

We switched to overmind and it's been great.

Hey, thanks for the comment u/sjieg! I don't have anything to add here, apart from suggesting the Overmind gem (https://github.com/DarthSim/overmind), which I just learnt about from another comment.

I run an app with a bunch of separate processes managed in a Procfile invoked by Overmind (https://github.com/DarthSim/overmind):

```

app-web: cd app && poetry run invoke server

app-vite: cd app && pnpm dev

app-storybook: cd app && pnpm story:dev

api: cd api && poetry run invoke server

docs: cd docs && npm run dev

marketing: cd marketing && source .env && npm run dev

```

Maybe it's my getting older, but I've found it _infuriating_ to remember which process is bound to 3003 vs 3002 vs 3001 and so on. Very grateful for this project so I can save myself a couple seconds of frustration every day — t/y OP for building it!

Use Overmind or cargo-runcc to run multiple commands in a single terminal, instead of running the server and the client in separate terminals

FYI: Your link for Overmind is to the wrong project. The process manager is https://github.com/DarthSim/overmind

The article currently links to a deprecated Angular.js project with the same name (https://github.com/geddski/overmind)

However, as you might expect, managing that becomes a bit of a chore in the long run, this is where my recommendation of Overmind comes in.
