docker-rails-example VS importmap-rails

I took a 13,000 line Rails 7.0 app and updated it to 7.1. I had to change 1 line of test configuration code to make everything work.

I would say that's a success for having an easy upgrade path. Now the fun part is going back to refactor some of the code to use the new features in 7.1.

If anyone is curious, I updated my Rails / Docker example app to use 7.1 too https://github.com/nickjj/docker-rails-example. Even though Rails 7.1 comes with a Dockerfile, there's still a lot of opinions you can add such as using Docker Compose to have a fully working out of the box experience that works in development and production -- complete with Postgres, Redis, Action Cable, Sidekiq and more.

Even though Rails 7.1 comes with a Dockerfile, there's still a lot of opinions you can add such as using Docker Compose to have a fully working out of the box experience that works in development and production.

If anyone is interested in that, I updated my example Rails app https://github.com/nickjj/docker-rails-example to use Rails 7.1 a few hours after 7.1 dropped.

If you're itching for Docker compatibility I maintain https://github.com/nickjj/docker-rails-example.

There's https://github.com/nickjj/docker-rails-example if you're looking for an end to end 1 command solution that works in dev and prod. It pulls together Puma, Sidekiq, Action Cable, Postgres, Redis, esbuild and Tailwind. It's all set up and ready to use Hotwire as well.

If anyone is looking for a more complete guide I put together this a while back: https://nickjanetakis.com/blog/a-guide-for-running-rails-in-...

The post also includes a ~1h hour ad-free YouTube video. It includes running Rails and also Sidekiq, Postgres, Redis, Action Cable and ties in esbuild and Tailwind too. It's all managed by Docker Compose.

The example app is open source at https://github.com/nickjj/docker-rails-example and it's optimized for both development and production. No strings attached.

If you're interested I've created https://github.com/nickjj/docker-rails-example with a base project using Docker Compose, Postgres, Redis, Sidekiq, Tailwind and esbuild.

I create an Up controller https://github.com/nickjj/docker-rails-example/blob/main/app/controllers/up_controller.rb and then have Uptime Robot https://uptimerobot.com/ hit it every few minutes.

It is implemented as a thor task in lib/importmap/cmmands.rb

With importmaps (https://github.com/rails/importmap-rails) and Hotwire (https://hotwired.dev/), you write plain js and serve it.

Also packages are served via CDN. There is no tree shaking. Rails got rid of the whole bundling step.

Importmap audit - “checks the NPM registry for known security issues”

It worked, but JS changes were not coming through. Digging into the Importmap docs (see 'sweeping the cache', it monitors changes according to the setting config.importmap.cache_sweepers. So, by adding the locations where I have my JS files, I also got JS changes passed through.

You can't use TypeScript, or anything that requires pre-compile, with importmap. answered issue

Let's begin by installing the necessary dependencies. The first gem generates the importmap object, manages caching, and helps with library installations, among other things. I recommend reading the entire readme to become familiar with its capabilities. The second gem will be discussed later, it is used to compile JSX files. Gemfile

Yeah, those were brand new right around the time I started this project a few years ago with Rails 7 (or was it 6.1?). I actually ended up removing them in favor of importmap-rails since I wanted as simple of a frontend as possible and I wasn't sure of relying on what was, at the time, a brand new way of doing frontend work. Things change so quickly in JS-land that I'm always hesitant to make something a dependency unless it has a strong track record of being continuously maintained.

Also, installing StimulusReflex seems quite not easy for the moment: It seems there are some quirks along the way if you're using import-maps for managing javascript dependencies as I do. Embracing the Rails way at least prevents you from this sort of issue.
