Spacer Components introduced in ViewComponent 3.20

This article was originally published on Rails Designer

Version 3.20 of ViewComponent introduced spacer_component.

It’s a new attribute that can be added to a collection to add another component between each item of a collection. It works like this:

<%= render(ProductComponent.with_collection(@products, spacer_component: SpacerComponent.new)) %>

This will then render SpacerComponent‘s between each ProductComponent. Pretty cool.

If you think, you’ve seen this feature before. You could be right. It was inspired by Rails’ collection partial rendering.
