Given a large-ish JSON, browse it interactively in terminal.

$ output_long_json
{"packages":[{"name":"ba... <fill up entire screen>

It is already possible with repeated invocation of jq:

$ output_long_json | jq ''
{
  "packages": [
    {...
<better, but it dives in depth-first and I don't see top-level elements>

$ outout_long_json | jq 'keys'
[
  "packages",
  "resolve",
  "target_directory",
  "version",
  "workspace_members",
  "workspace_root"
]
<OK, now I want to enter "resolve" and see what's here>

$ outout_long_json | jq '.resolve | keys'
...

But is there maybe TUI way?

Imagined:

$ output_long_json | json_browse
-----------
| /
|   packages 
| * resolve
|   target_directory
|   ...

-----------
| /resolve
| * nodes
|   keys

----------
| /resolve/nodes
| * [0]
|   [1]
|   [2]
...

In case anyone chances on this question from a search engine, I found an answer.

fx is a command-line utility that allows TUI-style interactive browsing of JSON data. You can fetch that package through NPM or download a binary from the link.
