Benchmark your JS projects with nanosecond resolution.
- Utilizes
process.hrtimefor 1ns resolution - Colorful formatting with nice units
- No dependencies, only ~150 lines of code: as lightweight as possible to not interfere with benchmarked code
- No code for estimating running time - specify samples manually
- Shows relative margin of error, min/max runs only if it's high
npm install --save-dev micro-bmark
import bench from 'micro-bmark';
(async () => {
await bench('printing', () => Promise.resolve(0));
await bench('base', () => Promise.resolve(1));
await bench('sqrt', 10000, () => Math.sqrt(2));
})();Example output:
getPublicKey() x 6,072 ops/sec @ 164μs/op ± 8.22% (min: 143μs, max: 17ms)
sign x 4,980 ops/sec @ 200μs/op
signSync x 4,671 ops/sec @ 214μs/op
verify x 969 ops/sec @ 1ms/op
recoverPublicKey x 890 ops/sec @ 1ms/op
getSharedSecret aka ecdh x 585 ops/sec @ 1ms/op
