I recommend using a recursive component structure for nested comments. For data, you can use a JSON tree structure where each comment has:
- id: unique identifier
- parentId: to track the parent comment
- content: the comment text
- author: author information
- timestamp: date of creation

Great point about the data structure! I've been considering a flat structure with a recursive component tree. What about using a flat database with a JSONB field for comments? That could simplify queries.

I've implemented a similar structure in React. The key is to use a recursive component that renders children based on the parentId. Performance-wise, I've found that virtualizing the comments list works well for deep trees.

For UI implementation, I recommend using a tree view component. There are great libraries like react-treeview or vue-nested. They handle the rendering of nested elements efficiently.

I've found that using a flat structure with a recursive component works best for performance. We store each comment as a separate row in the database, and then use a recursive component to render children. This way, we can use virtualization for long comment threads.

I'm building a forum application and want to implement nested comments. What are the best practices for structuring the data and UI for this?
I've considered using a tree structure where each comment has a parent_id. However, I'm concerned about performance with deep nesting.
