What?

Comparing the performance of native Node.js crypto utility vs libraries NanoID and UUID (v4).

Why?

We may reach for certain libraries because "everyone uses it" without asking what is the tradeoff?

How?

Created three scripts that all work the same: import the utility and then run it 10 million times.

const { utility } = await import('...');

for (let i = 0; i < 10000000; i++) {
    utility();
}

Then I used hyperfine to run each script at least 10 times and take the average.

hyperfine 'node uuid.js' 'node crypto.js' 'node nanoid.js' --warmup 3 --min-runs 10
