chore(ci/pr): print size of respec-w3c

[sidvishnoi]

It'll show up in "headless tests" step:

This is very cute, but it would be more cute 🐨 if it showed in comparison to the old build... otherwise, it doesn't mean much, right?

[sidvishnoi]

That would require building twice..
There's https://github.com/preactjs/compressed-size-action to do the heavy lifting, but only tells of compressed size. I'm interested in both compressed and uncompressed. I might create an action for that maybe 🐱

[marcoscaceres]

That would require building twice...

Hmm... could we look at sizes before "npm run build:w3c" runs, then store them somewhere?

[sidvishnoi]

Building adds like 3-4 seconds, so I think might be okay to be build twice.
Storing adds its own maintenance issues.

[marcoscaceres]

Building adds like 3-4 seconds, so I think might be okay to be build twice.

Yeah, that's fine. It's only for us, after all.

Storing adds its own maintenance issues.

Oh, I was thinking just a simple environment variable, like:

ORIGINAL_BUILD_SIZE=$(stat -f%z builds/respec-w3c.js)

Just for quick comparison.

[sidvishnoi]

That would be comparing to previous release. I'm interested in comparing since last commit to base branch.

[sidvishnoi]

Unless you mean comparing size with the one we just built in previous step, which is something I'll do when I create that action.

[marcoscaceres]

Ok cool.

[sidvishnoi]

Will build an action later based on:
