Slim VS Ruby on Rails

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.

This config sets a ”medium“ font weight for our form labels by default. Now, suppose we want a specific input’s label to be bold instead, we might want to try the following naive approach (we’re using the Slim template notation here):

[0] is a my favorite demonstration of it.

Here's a real life example: Imagine a Ruby on Rails app on which a team of developers are working. The code is hosted on GitLab and all the work is coordinated using GitLab issues. In other words: For every commit, there's an associated issue and the issue number acts as a sort of primary key for documentation, time reporting and so forth. This convention has a few advantages, most notably the ability to easily learn more about how, when and by whom features were implemented as well as how this implementation came to be.

Ruby on Rails is regarded as one of the best ruby frameworks. It was the primary language in developing big projects such as Twitter and helped the language boost the community. Often referred to as “Rails,” Ruby on Rails is a web development framework with an MVC control structure and currently running its 6.1 version. The 16-year-old language has dramatically influenced the web development structures and managing databases, web pages, and other components on a web application.

In Rails 7.1, a new option _instance_methods is introduced, allowing developers to opt-out of the automatic generation of instance methods for enums. When enum is defined with _instance_methods: false, Rails will no longer generate methods like pending?, processed?, etc.

Rails isn't super opinionated about database writes, its mostly left up to developers to discover that for relational DBs you do not want to be doing a bunch of small writes all at once.

That said it specifically has tools to address this that started appearing a few years ago https://github.com/rails/rails/pull/35077

The way my team handles it is to stick Kafka in between whats generating the records (for us, a bunch of web scraping workers) and and a consumer that pulls off the Kafka queue and runs an insert when its internal buffer reaches around 50k rows.

Rails is also looking to add some more direct background type work with https://github.com/basecamp/solid_queue but this is still very new - most larger Rails shops are going to be running a second system and a gem called Sidekiq that pulls jobs out of Redis.

I'm looking forward to see what extractions from this will land on rails. For example: https://github.com/rails/rails/issues/50454

Here is what strict_loading does (source):

Kamal is a wonderfully simple way to deploy your applications anywhere. It will also be included by default in Rails 8. Kamal is trivial, but I don’t recommend using it on your development machine.
