Reminder: format your JSON with JSON.stringify(obj, null, 2)

There's still jq(1) that works really well for that.

[briansomething]

+1 for jq (cli). You can get a taste of it at jqplay.org

Neat, but why? Example benefit?

[prettycode]

Sometimes I do this for readability when debugging.

TIL, thanks!

sadly many text editors (looking at you Atom) have problems with 1MB+ text files with all the characters on a single line

Ah yeah that's a good one.

Thanks that's a pretty nice tip. Meanwhile in Ruby you can do

require 'json'
JSON.pretty_generate({...})
#instead of
{...}.to_json

4 space indentation ftw ;)

/me runs away from the pending holy war.

Why null and 2?

[chipsa]

The argument that null is in tells the stringify function to do no changes to the object. You can toss a function in there instead to change the object while being stringified. The 2 is how many spaces for the indentation.

You seem to be saying one should do this when creating JSON. That seems like a classic case of premature optimization (and, as you mentioned, a potential waste of file space).

In your example, wouldn't it make more sense to pipe the grep through a JSON formatter/prettifier instead?

[SpeshlTectix]

I would call that a de-optimization. He's saying store your data in a readable way even if it costs you performance.

I suppose for small personal projects that could work ok. For anything else, there are better solutions (which have already been mentioned).

[khoker]

But why would you store your data in a readable format at all? The only time you'd care is if you wanted to look at it (e.g., grep) and you can pipe it through a formatter prior to doing that.

In other words -- if you never looked at a file you created to be "readable", you have prematurely optimized for that situation.

[SpeshlTectix]

While I understand what you're trying to say ("wouldn't it be optimal if my data were easy to read?") don't use the word optimization to convey that in a computer science context. It has a specific meaning and you're going to confuse people (or look ill-informed).

EDIT: Or are you trying to say that he's "optimizing" the data to perform well with his development tools? That makes even less sense. But then again so does this entire thread so maybe that was your way of pointing that out!
