jsbundling-rails VS Foreman

I think this is more like a demo - you will not get the same features as jsbundling-rails by only following instructions in the video. For that you will need to change some other files as well. You can find out what files to be added/changed from the install script. The important bits are mostly the same as in the video, but some supplement parts are not mentioned in the video. Some people actually reported in the comment that they can't deploy such app, but I think it depends.

I'm sorry, I didn't see that in your title. Using esbuild is 100% supported by Rails through this gem https://github.com/rails/jsbundling-rails. Have a look at the docs there to make sure that you're setup correctly.

Rails applications are bundler-agnostic. They do not care how you bundle your javascript code. It just expects whatever comes from the bundler to be placed under app/assets, so the asset pipeline processes it. We can see this in the official jsbundling-rails gem, which consists of scripts to install different bundlers and configure a default npm build command to generate our bundles—no interaction whatsoever with the Rails configuration. This black-box bundler logic allows us to change and update our bundler system without tuning any other aspect of our Rails application.

Hello, this is my first time setting up a rails app that also uses react, I am using https://github.com/rails/jsbundling-rails I went with esbuild because I am following this tutorial on setting it up https://www.youtube.com/watch?v=yoLJXjEV2nM, however when I run bin/dev in the terminal I get the error bin/dev: 8: exec: foreman: not found

You first install your asset handlers as you need them for your project. They can be anything from rails/jsbundling-rails and rails/tailwindcss-rails to webpacker or something custom.

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.

The Rails https://github.com/rails/jsbundling-rails gem lets you pick between esbuild, rollup and Webpack. If Turbopack ends up being popular then jsbundling should be able to support it.

The nice thing about Rails now is there's no direct integration like Webpacker once was. Now we can basically use the JS tool straight up and Rails will just look at assets in a specific directory, it doesn't matter what tool generated it.

I was confused because there is https://github.com/ddollar/foreman and https://github.com/theforeman/foreman

Are you looking for something like https://github.com/ddollar/foreman?

Btw, there's a large number of tools that use the Procfile file format, including what appears to be the original one, written in Ruby https://github.com/ddollar/foreman (the readme has links to a partial list of foreman clones)

But I agree that overmind is the best of the bunch

We ran our app via bin/dev. You can find the div file inside ./bin/dev folder. It is a ruby wrapper over the process manager forman which manages Procfile-based applications. Rails automatically install foreman gem but it doesn’t bundle it because forman recommends NOT to do 🚫

Note: Alternatively, you can install Foreman on your computer and execute the ./bin/dev command to simultaneously generate the TailwindCSS classes and also run the Rails server in a single terminal.

using foreman with the foreman start -f Procfile.dev command to start my app.

Obviously, we still need to install a runner to handle this procfile. Meet foreman, or one of it's forks. Foreman is a Ruby script, so for that you'll need to have Ruby installed. There are many forks though. Such as shoreman, which is a dependency free shell script, or node-foreman, which is a javascript fork. I go with node-foreman, for the simple reason that I'm a node guy and I like that I can npm install it to the dependencies of my node projects.

Comes Foreman to the rescue! Foreman is a gem (for Ruby, but it already ported to many others languages) that will load a Procfile and start/stop the services configured by demand.

A bin/dev file - This should be how you run your application in development. It runs (and optionally installs if you don't have it) Foreman, so you can run your server and build Javsacript on the fly

So far, whenever I started the Rails app, I launched these supporting processes in multiple terminal windows. This week, I learned a new way to do this using a single command using the Foreman gem, which has saved me a lot of time.
