Adds a size property to the new Icon component so that we don't have to use the component's CSS classes for sizing.

Hey 👋

Only had a quick glance at this, but my immediate thought was - how come you decided you wanted to move away from class? It kinda feels like class is the right tool for this? Maybe its just I don't understand the background.

Would be good to understand some of the reasoning behind this!

Thanks,

John

Hey @johncowen ! Yeah there's a bit of a story there :D

So Icon replaces an older component ICon, and there we allowed passing through an arbitrary number that would get passed to the SVG's height and width attributes in the template. Icon uses the SVGs from the structure-icons repo so we wanted a standard set of sizes and those got implemented via classes on the component, and the first pass was using those classes when we needed them. So in a way we went from one extreme with no restrictions on size, to another extreme where it was sized just via CSS classes, to somewhere in the middle where we restrict the allowed classes via a property.

The motivation here, moving from classes specific to the component all over the application to a property on the component, is really just one of encapsulation. The sizing classes are implementation details and it felt like having to use them for sizing all over the application was leaking those details. If the sizing classes are encapsulated in the component itself, they can be changed in one spot if needed at a later date. This encapsulation also keeps the interface / api surface of the component in JS, not a combination of JS and CSS which is a tidier boundary. If an application needs to do additional styling with it, there's still that option via CSS, but it's then an application concern, not a component one.

Oki doki, just seems strange to me that I set sizes of things for everything else using a class.
Also, on this component if I want to change the size I use the size attribute, but if I want to change the color I use class=""?

Most importantly though it needs to feel right to you, so as long as you are happy with it, it's all good with me!

Code looks fine, I had a comment, but then went 'oh yeah, I see now!', but left the comment in just to see if I guessed right


storiesOf('Icon/', module)
.addParameters({ options: { showPanel: false } })
.addParameters({ options: { showPanel: true} })

Not sure if you left this in by accident (showPanel: true)? Ah, maybe you want the panel in now as you have a setting you can tweak.? Will leave this comment in just incase, but 99% sure this is good

Yeah, this is so that the knobs panel shows up when you click Icon in the sidebar, otherwise it's hidden. We usually hide it if we're not using the knobs decorator, but since I added it here, I flipped it to true.

Sweet gotcha 👍
