Vite + TypeScript PWA that mirrors the Android app's core features: - Pre-processed shelter data (build-time UTM33N→WGS84 conversion) - Leaflet map with shelter markers, user location, and offline tiles - Canvas compass arrow (ported from DirectionArrowView.kt) - IndexedDB shelter cache with 7-day staleness check - Service worker with CacheFirst tiles and precached app shell - i18n for en, nb, nn (ported from Android strings.xml) - iOS/Android compass handling with low-pass filter - Respects user map interaction (no auto-snap on pan/zoom) - Build revision cache-breaker for reliable SW updates Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com> |

pretty-bytes
Convert bytes to a human readable string:
1337→1.34 kB
Useful for displaying file sizes for humans.
Note that it uses base-10 (e.g. kilobyte). Read about the difference between kilobyte and kibibyte.
Install
npm install pretty-bytes
Usage
import prettyBytes from 'pretty-bytes';
prettyBytes(1337);
//=> '1.34 kB'
prettyBytes(100);
//=> '100 B'
// Display with units of bits
prettyBytes(1337, {bits: true});
//=> '1.34 kbit'
// Display file size differences
prettyBytes(42, {signed: true});
//=> '+42 B'
// Localized output using German locale
prettyBytes(1337, {locale: 'de'});
//=> '1,34 kB'
API
prettyBytes(number, options?)
number
Type: number
The number to format.
options
Type: object
signed
Type: boolean
Default: false
Include plus sign for positive numbers. If the difference is exactly zero a space character will be prepended instead for better alignment.
bits
Type: boolean
Default: false
Format the number as bits instead of bytes. This can be useful when, for example, referring to bit rate.
binary
Type: boolean
Default: false
Format the number using the Binary Prefix instead of the SI Prefix. This can be useful for presenting memory amounts. However, this should not be used for presenting file sizes.
locale
Type: boolean | string
Default: false (No localization)
Important: Only the number and decimal separator are localized. The unit title is not and will not be localized.
- If
true: Localize the output using the system/browser locale. - If
string: Expects a BCP 47 language tag (For example:en,de, …) - If
string[]: Expects a list of BCP 47 language tags (For example:en,de, …)
minimumFractionDigits
Type: number
Default: undefined
The minimum number of fraction digits to display.
If neither minimumFractionDigits or maximumFractionDigits are set, the default behavior is to round to 3 significant digits.
import prettyBytes from 'pretty-bytes';
// Show the number with at least 3 fractional digits
prettyBytes(1900, {minimumFractionDigits: 3});
//=> '1.900 kB'
prettyBytes(1900);
//=> '1.9 kB'
maximumFractionDigits
Type: number
Default: undefined
The maximum number of fraction digits to display.
If neither minimumFractionDigits or maximumFractionDigits are set, the default behavior is to round to 3 significant digits.
import prettyBytes from 'pretty-bytes';
// Show the number with at most 1 fractional digit
prettyBytes(1920, {maximumFractionDigits: 1});
//=> '1.9 kB'
prettyBytes(1920);
//=> '1.92 kB'
space
Type: boolean
Default: true
Put a space between the number and unit.
import prettyBytes from 'pretty-bytes';
prettyBytes(1920, {space: false});
//=> '1.9kB'
prettyBytes(1920);
//=> '1.92 kB'
