Fx – Terminal JSON Viewer
This fx rewrite is very exciting. I'll have to try it. I thought of fx as a wrapper around jq, that allowed quick iteration over building jq scripts. Sort of an Ultimate Plumber [1] but only for jq. It looks like it is now more like a JavaScript processor plus an interactive viewer.
Someone mention Visidata[2]? VisiData is also a TUI that is great on tabular data, and it can work with json. If your JSON is mostly tabular in nature, Visidata does a great job at showing that data and allowing you to explore it. A lot of json I deal with is tabular-like data. There is a great tutorial [3], that can help you get your bearings with Visidata. Once you understand those basics you might want to look at this thread [4] for what commands you can use with json.

An interactive wrapper around `jq`
Fun. But I can achieve the same result (I think) with ultimate plumber and regular jq, but without being restricted just to jq. Feel free to correct me.

Toolong: Terminal application to view, tail, merge, and search log files
The code base seems like a good reference as a small Python project.
My fav option in this class of apps: https://lnav.org/ It lets you use journalctl with pipes as requested here: https://github.com/Textualize/toolong/issues/4

Logdy.dev – web based logs viewer UI for local development environment
For local development, I cannot recommend lnav[1] enough. Discovering this tool was a game changer in my day to day life. Adding comments, filtering in/out, prettify and analyse distribution is hard to live without now.
I don't think a browser tool would fit in my workflow. I need to pipe the output to the tool.

Ask HN: How does `lnav` run its playground which you can just SSH into?
It looks like they run an SSH server inside a Docker container defined by this Dockerfile [1]. This uses the ForceCommand directive in the sshd_config file to ensure that a specific command is run when a user connects (rather than the user connecting directly to a shell).
Depending on whether the user connects as the `playground` or `tutorial1` user they interact with a bash script that is either [2] or [3].

Structured Logging with Slog
> I also don't see something else I might want: a way to have a different "view" for certain log messages; maybe to switch between filtering/viewing particular ones, maybe to just have line-format be conditional based on the detected format.
Have a look at the following comment on an issue that might be similar to what you're thinking of:
https://github.com/tstack/lnav/issues/1065#issuecomment-1602...
> I guess I can sort of do this based on `module-field`? but I might want it lighter-weight/finer-grained than that.
Unfortunately, the "module-field" does not work for JSON logs at the moment. It's something I should really fix.
Ultimately, lnav has existed for almost two decades now and I use it every day. So, it's always seeing improvements. If you're having a problem with it, file an issue on github. I don't always get around quickly to fixing other folks feature requests / issues, but it tends to happen eventually.
Thanks.
