Goal: have a personal blog, and try out another point in the 'modular
app design with elixir' space.

Designing OTP systems with elixir had some interesting ideas.

defmodule FirehoseWeb.CoreComponents do
@moduledoc """
Provides core UI components.
At first glance, this module may seem daunting, but its goal is to provide
core building blocks for your application, such as tables, forms, and
inputs. The components consist mostly of markup and are well-documented
with doc strings and declarative assigns. You may customize and style
them in any way you want, based on your application growth and needs.
The foundation for styling is Tailwind CSS, a utility-first CSS framework,
augmented with daisyUI, a Tailwind CSS plugin that provides UI components
and themes. Here are useful references:
* [daisyUI](https://daisyui.com/docs/intro/) - a good place to get
started and see the available components.
* [Tailwind CSS](https://tailwindcss.com) - the foundational framework
we build on. You will use it for layout, sizing, flexbox, grid, and
spacing.
* [Heroicons](https://heroicons.com) - see `icon/1` for usage.
* [Phoenix.Component](https://hexdocs.pm/phoenix_live_view/Phoenix.Component.html) -
the component system used by Phoenix. Some components, such as `<.link>`
and `<.form>`, are defined there.

Renders an input with label and error messages.
A `Phoenix.HTML.FormField` may be passed as argument,
which is used to retrieve the input name, id, and values.
Otherwise all attributes may be passed explicitly.
## Types
This function accepts all HTML input types, considering that:
* You may also set `type="select"` to render a `<select>` tag
* `type="checkbox"` is used exclusively to render boolean values
* For live file uploads, see `Phoenix.Component.live_file_input/1`
See https://developer.mozilla.org/en-US/docs/Web/HTML/Element/input
for more information. Unsupported types, such as hidden and radio,
are best written directly in your templates.

use Gettext, backend: FirehoseWeb.Gettext

gettext("Here is the string to translate")
# Plural translation
ngettext("Here is the string to translate",
