Benchmark

A wise man once said:

Not trying to measure our members, so to speak, but you must log more data next time. @jets-fool, 2022.

And actions prove more than words, here are my numbers:

About the suits

NpmPrune:

• Clean the dependencies with npm prune --production
• Zip the node_modules with archiver
• Restore the dependencies back (this can be skipped if you run on CI/CD)

NpmPrune (skipping restore):

• Clean the dependencies with npm prune --production
• Zip the node_modules with archiver

Node Modules Packer:

• Just zip the node_modules, that's it.

How to Run

First, install dependencies and build the library with:

# inside root folder
npm ci
npm run build
# inside benchmark folder
npm ci

Then run this script:

npm run benchmark

Setup: Ryzen 3 2200g, 32 GB 3200MHz, SSD m2 3500MB/s read, 3000MB/s write.

Npm Prune Results:

(index)	endTime	outputSize
0	38.24s	29.31 MB
1	39.64s	29.31 MB
2	40.44s	29.31 MB
3	41.91s	29.31 MB
4	35.80s	29.31 MB

Npm Prune (skipping restore) Results:

(index)	endTime	outputSize
0	23.56s	29.31 MB
1	28.76s	29.31 MB
2	23.43s	29.31 MB
3	23.22s	29.31 MB
4	23.09s	29.31 MB

Node Modules Packer Results:

(index)	endTime	outputSize
0	7.48s	17.44 MB
1	7.07s	17.44 MB
2	7.04s	17.44 MB
3	7.28s	17.44 MB
4	7.39s	17.44 MB

Node Modules Packer (minified) Results:

(index)	endTime	outputSize
0	10.13s	13.19 MB
1	10.03s	13.19 MB
2	9.99s	13.19 MB
3	10.45s	13.19 MB
4	10.38s	13.19 MB

Summary:

suite	endTime (mean)	outputSize (mean)
Npm Prune	39.21s	29.31 MB
Npm Prune (skipping restore)	24.41s (61% faster)	29.31 MB (0% lighter)
Node Modules Packer	7.25s (441% faster)	17.44 MB (~40% lighter)
Node Modules Packer (minified)	10.20s (284% faster)	13.19 MB (~55% lighter)

So running this library without doing any optimization can give you a speed improvement of 441% (284% minified) and reducing your zip file by ~40% (~55% minified), you can further reduce the size of the zip with a few more tweaks.

But, I don't know about you, but for me the big benefit is not having to run npm prune --production, I use Webstorm and this command makes my Webstorm re-index all node_modules making me lose more seconds of my life .
