In the latest version of @rolldown.rs, JSON imports are tree-shaken! No more superfluous JSON values in your bundle, only these that you actually access. Without any change of code or config ✨ Interested in the code? Then check out the PR! github.com/rolldown/rol...

Accessing only used keys shrinks the bundle.

Is it better for performance to convert the JSON to JavaScript values or keep it as JSON in the bundle and parse on the client? I’ve seen differing opinions.

I've only seen that json.parse is faster than js for large objects. Can you share where you have seen the opposite?

That’s what I’ve seen too but I also have that use case a lot and would like to control when I use one or the other.
