Slim VS Simple Form

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.

I also tend to use gems like simple_form to generate my form HTML, and this saves me from having to maintain a lot of view code to outputting translated content onto forms. Also simple_form has it's own i18n convention that compliments the Rails default pretty well.

I followed the RailsCasts tutorial and its GitHub page to set up the gem in my application and used it for all of the models in my application. It was working perfectly fine showing the default error message at the top and the validation message at the bottom of their respective fields.

Okay now for those "buttons". We don't want just a normal button or link though. This is where we need the booking update form. Let's use simple_form_for (check out the docs here).

There are many ways to create a form in Rails, whether you want to create a form with Form builder from Rails itself or maybe using third party gem like simple_form. Of course, simple_form is not the only option we have to build form in rails, there are alternatives out there such as formtastic, cocoon, nested_form, etc. However, in this post I'm going to give you a basic use case to use simple_form in Rails application.

I usually go with simple_form, I customise my forms by configuring it and letting it handle the repeated rendering.

Simple Form gem

The biggest unclear area that we saw related to view components were forms. There were glimpses of compatibility issues with Rails form helpers in the documentation and we saw a recent effort of the team to mitigate them. Moreover, we were used to building forms with Simple Form which added another variable to the equation. And, in general, we considered the Rails form builders (as well as the Simple Form builder) a system of form-related components in the first place so we were unsure how this would fit into the View Components ecosystem or whether we should even try to do that.
