micro-bmark

Benchmark your JS projects with nanosecond resolution.

• Precise: 1ns resolution using process.hrtime
• Lightweight: ~200 lines of code, no dependencies - to not interfere with benchmarked code
• Readable: utilizes colors and nice units, shows rel. margin of error only if it's high

Usage

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% [143μs..17ms]
sign x 4,980 ops/sec @ 200μs/op
verify x 969 ops/sec @ 1ms/op
recoverPublicKey x 890 ops/sec @ 1ms/op
getSharedSecret x 585 ops/sec @ 1ms/op
