Why ViewComponent::Base#render does not reuse view context?

[joelmoss]

So looking at https://github.com/github/view_component/blob/main/lib/view_component/base.rb#L145-L147 which says that render will only reuse the view_context when not rendering a component.

I have a component that renders a child component within a call and I need it to use the same view context. So was wandering why the above is the way it is, and why rendering a child component does not also reuse the view context?

thx

Just an educated guess here, but I'd imagine it's a deliberate choice. It's probably where some of the performance benefit of ViewComponent comes from relative to plain Action View. @BlakeWilliams has something in the works that might change this if it's merged, however.

Surely reusing the view context is more efficient?

This will no longer be the case in v4: #2287
