docker-rails-example VS Slim

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.

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.

I spent a few days of my spare time building a VS Code extension that would bring better syntax highlighting for the Slim template language to the editor. I quite enjoyed most of the process so I’d like to share what I learned.

I think they mean Server Side Rendering (normal rails controllers/views), and Slim is just the name of the templating engine. It's a little nicer than the default ERB. https://github.com/slim-template/slim

There's also SSR with react and other js frameworks, but I don't think that's what they meant.

I use something very similar on https://lunar.fyi and https://lowtechguys.com but I wouldn’t call this “simple” anymore.

They use Jinja templating, I prefer Slim (https://github.com/slim-template/slim#syntax-example) which has a more Pythonic syntax (there is plim [0] in Python for that)

I use Tailwind as well for terse styling and fast experimentation (allows me to write a darkMode-aware and responsive 100 line CSS in a single line with about 10 classes)

For interaction I can write CoffeeScript directly in the page [1] and have it compiled by plim.

I run a Caddy static server [2] and use Syncthing [3] to have every file save deployed instantly to my Hetzner server.

I use entr [4] and livereloadx [5] to rebuild the pages and do hot reload on file save. All the commands are managed in a simple Makefile [6]

You can already see how the footnotes take up a large chunk of this comment, this is not my idea of simple. Sure, the end result is readable static HTML and I never have to fight obscure React errors, but it’s a high effort setup for starters.

Simple for me would be: write markdown files for pages, a simple CSS for general styling (should be optional), click to deploy on my domain. Images should automatically be resized to multiple sizes and optimized, videos re-encoded for smaller filesize etc.

I have mostly implemented that for myself (https://notes.alinpanaitiu.com/How%20I%20write%20this%20blog...) but it feels fragile. I’d rather pay for a professional solution.

Checkout slim https://github.com/slim-template/slim it's a templating language

And this is what the HTML looks like (I'm using slim):

The template renders the tag and inside it the link and the counter itself (the Slim template language and Tailwind styling are used here, hopefully the notation is sufficiently self-explaining):

In this part of the series, let's explore another popular templating language, Slim.

Templating languages are widely used in Web development and two of the most popular ones are Pug and Slim. In this series, we're going to learn the basics of these two and hopefully they would help improve your workflow further.

You may want to checkout slim I'v tried ERB, SLIM, and HAML and absolutely sware by slim it's very easy to use and saves a ton of typing compared to ERB.
