modd VS overmind

Modd is a library that makes hot reloading possible in Go applications. To use it, install it on your machine using the command below:

There's also modd[0] which allows for many file watch pattern -> command combos to easily be defined & run simultaneously from a modd.conf file.

i was using cortesi/modd for this while using docker. Since I change to Rancher with dockerd i wasn’t able to get live reloading working again, i also tried air but no luck.. out of curiosity did anyone have a similar issue?

Interesting. I've been using https://github.com/cortesi/modd for this for a while but I'll check this project out.

me likes: https://github.com/cortesi/modd A little more flexible for various files

I use a somewhat similar approach for Pirsch [0]. It's build so that I can run it locally, basically as a fully fledged staging environment. Databases run in Docker, everything else is started using modd [1]. This has proven to be a good setup for quick iterations and testing. I can quickly run all tests on my laptop (Go and TypeScript) and even import data from production to see if the statistics are correct for real data. Of course, there are some things that need to be mocked, like automated backups, but so fare it turns out to work really well.

You can find more on our blog [2] if you would like to know more.

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.
