Chokidar: Reduce package size

Created on 6 Sep 2018 · 9Comments · Source: paulmillr/chokidar

We can do better.

Ideas for 2.x:

Remove stuff from readdirp
Remove upath
Optimize fsevents

As of 2.0.4 with npm install -g cost-of-modules:

holy Moses, braces is 3mb? I just confirmed that myself. There has to be some duplication happening. I'll look into it and reduce as much as possible.

Pushed new version of readdirp with micromatch: 5.35M => 5.28M.

FYI - chokidar is currently 11.93M with 306 children on my machine...

Are you using chokidar in the browser?

jonschlinkert on 16 Apr 2019

@abritinthebay I don't think so — the new version is very small.

GREAT results for v3: 17x size reduction 4.78MB => 0.27MB; this could save NPM users 45 Terabytes of bandwith every single week

I’m just using it on disk. Latest published version, latest node version. I used the same tool you mentioned above.

This is what it shows in a project when I use it.
