Is there a way to have expandable/collapsible json in a node.js cli app?

I'm working on a node.js CLI tool that works with large json objects. I'd love to be able to display root nodes and then allow the user to expand and collapse object nodes as needed. Are there any packages available that setup this kind of functionality?

Here's an example of the kind of expand/collapse behavior I'm looking for in a browser

There's precedence for this kind of functionality in modules like Inquirer.js

I haven't found a package that will setup completely the functionality you're looking for. But you could take a look at blessed (a fantastic library for terminal node-js applications).

Look under the lists widget and you have a highly extensible API for creating interactive lists (whether with the mouse, or the keyboard) inside a terminal.

You could use something like the items option in the list which takes "an array of strings which become the list's items".
Or, you have the potential to use Blessed's Layout widgets which mimic CSS functionality inside the terminal.

With that tool it shouldn't be very difficult to create a simple JSON list that's interactive.
