Report aggregate stats by folder and file type?

[slorber]

I'm using this project on Docusaurus, a static site generator, to monitor the build output size

Example PR comment: https://github.com/facebook/docusaurus/pull/10470#issuecomment-2324697764

Monitoring by file size is great, but in our case, we emit too many output files to monitor them all without creating noise, so I only added a "representative" list of output files.

What would be a great addition for us would be to have the ability to compare the before/after size of a whole folder. Eventually be able to break it down by file type, so that we could detect if JS, CSS, or HTML total output size increases after a PR.

I'm wondering if this could be part of this project, or if it's out of scope and should be a separate tool.

Interesting, would you only want the folder and file types inside of it, replacing individual files altogether then? Something like the following maybe:

Directory	Type	Size	Change
compat/dist/foo	CSS	3.53 kB	-567 B (-13.83%)	👏
compat/dist/foo	JS	3.44 kB	-582 B (-14.46%)	👏
compat/dist/foo	HTML	3.6 kB	-571 B (-13.71%)	👏

Or perhaps:

Directory	Type	Size	Change
compat/dist/foo	All	9.53 kB	-567 B (-13.83%)	👏
	CSS	3.53 kB	-567 B (-13.83%)	👏
	JS	3.44 kB	-582 B (-14.46%)	👏
	HTML	3.6 kB	-571 B (-13.71%)	👏
compat/dist/bar	All	9.53 kB	-567 B (-13.83%)	👏

(Ignore the nonsensical sizes that don't add up, I quickly copy/pasted from Preact 😄)

Or in addition to the existing output? Just thinking if it's a toggled either/or situation or just a new output table.

I think it would be a reasonable addition though!

Thanks!

I think a separate table makes more sense. I guess something like this could be nice, with the ability to count the number of files and the change too.

For flexibility, I'd break it down by extension and not just CSS/JS/HTML.

Folders	Count	Size	Change
website/build1	278 (+1 ⚠️)	666 kB	+34 B (+0.01%)
website/build2	10 (+0)	10 kB	+34 B (+0.01%)
TOTAL	288 (+1 ⚠️)	676 kB	+34 B (+0.01%)

ℹ️ Break down by extension

| Extension | Count | Size | Change | | :--- | :---: | :---: | :---: | | `.js` | 100 (+0) | 2 B | 0 B | | `.css` | 100 **(+1 ⚠️)** | 27.9 kB | 0 B | | `.html` | 100 (+0) | 27.9 kB | 0 B | | `.jpg` | 100 (+0) | 30.2 kB | 0 B |

Yeah that was just for a quick example, albeit using the names instead of the proper extension.

But this seems reasonable and I can see how many might want this. I'll take a look at this later this week if I get some time.

+1 this sounds like a really nice addition, in a monorepo the stats comment starts to get very noisy and unwieldy

Suggestion: would be nice to retain individual file stats in a collapsed section. Ie if you find a certain folder has increased you can then drill down to more indepth stats.
