Although there wasn’t any talk focused on TypeScript, we could feel that it was on everyone’s mind. Interestingly, TypeScript seems to be the obvious, default choice for everyone — but it still looks to be a bit scary to many of us. Some talks had types in their coding examples, and the speakers didn’t feel the need to explicitly explain what they were : types are now ubiquitous and expected.

One could think that components and component libraries are a solved problem : they definitely are not. Usually part of a larger Design System, they are still hard to implement : discussions revolved around the ideas of composition vs. configuration, flexibility vs. consistency, or whether a Design System was needed at all. The “spectrum of flexibility” concept is interesting :

I really liked the idea of “not ejecting” expressed by Sid Kshetrapal (Github) , which I understood as “not giving up control” over what is allowed to be rendered. Instead of allowing any component as a prop (in his example, a renderItem: React.ComponentType), we can leverage composition to achieve the same level of flexibility. From his slides :

iAdvize has its own Design System. On the flexibility spectrum, I think we are near the middle, leaning on the left (strict) side. It makes sense that a private component library is more strict and closed than a public one, as we favor predictability (easy to work with, easy to onboard new developers) over flexibility (we are our only client).
