Yesterday, @davidteren asked what is the easiest way to setup TailwindCSS with Rails 8 and having hot reload.

This is how I believe it is to do so in a few minutes.

First thing is to add the tailwindcss-rails gem to the project and to run the installer to create the Tailwind config files:

And now you can run bin/rails tailwindcss:watch to rebuild the CSS files on file changes.

If you use CSS classes in a directory not watched by default, you can add that to config/tailwind.config.js under the content key:

And to make your workflow even smoother, you can use Foreman to manage all the necessary processes for you. To set that up is also pretty simple. Create a bin/dev file with the following content:

Then create a file, named Procfile in the root of your project with the following content:

After this, running bin/dev in your terminal will start the Rails server and the Tailwind watcher process.

That's it. It shouldn't take more than a few minutes to set this all up.
If you want to read this in a blog format and copy+paste the code snippets, here is a link to an article:

If you incorporate these 3 simple changes to your application, you will level up your application's security posture.

Setup dependency vulnerability monitoring.
Using dependencies with known vulnerabilities is a huge security risk.
To mitigate this, you can setup a Github action to run bundle audit and yarn audit on your codebase regularly and patch when needed.

Did you know that you can create a single-file Rails application?

You shouldn't unless you are experimenting with something, but here is how it can be done:

🧵 👇

Let's create a file and call it "app" with the "ru"(rackup) extension. Then we need to use bundler inline to install the dependencies:

Next, we require Rails and configure Active Record to use a sqlite database and we define the database schema and create a model:

One of Ruby's great features is method chaining.
For instance, Active Record heavily relies on this and method chaining enables us to do cool things like User.where("active = 1").count.
Have you ever wondered how is that possible?
Let's look into it, it is pretty simple.
🧵👇

Let's use a simple example of having a user model and you want to be able to set a default password for your user when they signup via OAuth. So you want to be able to do something like this in your controller:
