si-prefix

library0.2.0jsnpmunverified

si-prefix v0.2.0 is a JavaScript library for converting numeric values into human-readable strings with SI or IEC prefixes (e.g., '35 mm', '2 KiB'). It wraps the si-prefix library for Node.js, offering basic formatting via si-prefix. Works with custom units and scales. Last updated 2021, no recent releases; minimal dependencies.

Code

Verified usage

Verified import paths — ran on the pinned version, not inferred.

default (si)

✓ import si from 'si-prefix'

✗ const si = require('si-prefix')

ESM default import; CJS require also works.

Unit

✓ import { Unit } from 'si-prefix'

✗ const Unit = require('si-prefix').Unit

Named export for Unit class.

Scale

✓ import { Scale } from 'si-prefix'

Named export for Scale class.

Demonstrates basic formatting with SI base units (metre, kilogram, byte) and custom unit creation with Scale and Unit.

import si from 'si-prefix'; // Basic formatting console.log(si.metre.format(0.035, ' ')); // '35 mm' console.log(si.kilogram.suffix(0.00000000094, ' ')); // 'ng' console.log(si.byte.convert(2048)); // [2, 'KiB'] console.log(si.byte.decimal.convert(2048)); // [2.048, 'kB'] // Custom unit const { Scale, Unit } = si; const scale = new Scale({ minor: true }); const unit = new Unit(scale, 'm'); console.log(unit.format(0.03, ' ')); // '3 cm'

Debug

Known issues

gotchakilogram is base unit; gram is not directly available as si.gram.

fix

Use si.kilogram.suffix(value) for grams, or create a custom gram unit.

affects: *

gotchabyte uses IEC binary prefixes (KiB, MiB, etc.) by default; use byte.decimal for SI prefixes.

fix

Access si.byte.decimal for SI prefixes (kB, MB).

affects: *

deprecatedSeparate flags for hecto/deca/deci/centi not implemented yet.

fix

Use Scale({minor: true}) to include these prefixes.

affects: 0.2.0
