[Jellyswitch](https://www.jellyswitch.com) is a coworking space management platform
In response to [this tweet](https://twitter.com/joelhawksley/status/1232674647327547394):
I recently began refactoring many of my partials into components. Along the way I discovered an interesting use case, which was to componentize the various bootstrap components I was already using.
Some examples:
- I've componentized the specific layout that I've designed using the grid system. I have defined a `FullWidthLayout` component that wraps its contents in the correct classes to give my layout a good design on both mobile and desktop. (On desktop, there is a sidebar, and on mobile, the sidebar floats on top in a collapsed fashion.)
- [Modals](https://getbootstrap.com/docs/4.4/components/modal/) are now componentized and accept arguments. I had them as partials before, but having ruby classes is an upgrade.
- [Breadcrumbs](https://getbootstrap.com/docs/4.4/components/breadcrumb/) same as above.
Here's one that I use a LOT: `OnOffSwitch`:
```ruby
class OnOffSwitch < ApplicationComponent
def initialize(predicate:, path:, disabled: false, label: nil)
@predicate = predicate
@path = path
@disabled = disabled
@label = label
end
private
attr_reader :predicate, :path, :disabled, :label
def icon_class
if predicate
"fas fa-toggle-on"
else
"fas fa-toggle-off"
end
end
end
```
```erb
<div class="d-flex align-items-center">
<% if !disabled %>
<%= link_to path, class: "text-body", remote: true do %>
<span style="font-size: 20pt">
<% if predicate %>
<span class="text-success">
<i class="<%= icon_class %>"></i>
</span>
<% else %>
<span class="text-danger">
<i class="<%= icon_class %>"></i>
</span>
<% end %>
</span>
<% end %>
<% else %>
<span style="font-size: 20pt">
<span class="text-muted">
<i class="<%= icon_class %>"></i>
</span>
</span>
<% end %>
<%= content %>
</div>
```
Here is an example of how this looks:

I have found that refactoring complex views is made easier and faster by first putting them into a component, extracting the conditionals and other logic into private methods and proceeding from there. And I wind up with a nice set of well-factored components and sub-components, with argument lists and validations. I think the rails community is going to benefit from this library, and I'm hugely appreciative of y'all's efforts on it!
I plan to release an early version of the bootstrap components we've developed at some point in the near future. I would love to collaborate and learn the most appropriate way to structure that contribution.
