convertem's Introduction

Convert 'em

Small library that helps with conversion. Could be very helpful when getting values from configuration files (like yaml, etc).

Installation

npm install convertem

Usage

  • toNumber - convert argument to a number or return null if conversion failed

    import { toNumber } from 'convertem';
    
    toNumber('42'); // 42
    toNumber('0x42'); // 0x42
    toNumber(42); // 42
    toNumber('true'); // 1
  • toBoolean - convert argument to a boolean

    import { toBoolean } from 'convertem';
    
    toBoolean('1'); // true
    toBoolean(42); // true
    toBoolean('True'); // true
    toBoolean('yes'); // true
    toBoolean('on'); // true
    
    toBoolean(); // false
    toBoolean(null); // false
    toBoolean(''); // false
    toBoolean('0'); // false
    toBoolean(0); // false
    toBoolean('FALSE'); // false
    toBoolean('No'); // false
    toBoolean('Off'); // false
  • toMilliseconds - convert argument to a milliseconds

    import { toMilliseconds } from 'convertem';
    
    toMilliseconds(42); // 42
    toMilliseconds('42'); // 42
    toMilliseconds('42 ms'); // 42
    toMilliseconds('42 s'); // 42000
    toMilliseconds('42 sec'); // 42000
    toMilliseconds('42 seconds'); // 42000
    toMilliseconds('42 m'); // 42000 * 60
    toMilliseconds('42 min'); // 42000 * 60
    toMilliseconds('42 minutes'); // 42000 * 60
    toMilliseconds('42 h'); // 42000 * 3600
    toMilliseconds('42 hours'); // 42000 * 3600
    toMilliseconds('1:30'); // 90000
    toMilliseconds('42:00:00'); // 42000 * 3600
    toMilliseconds(); // 0
    toMilliseconds(''); // 0
    toMilliseconds(null); // 0
  • fromMsToString - convert argument from milliseconds to backward-compatible string

     import { fromMsToString } from 'convertem';
    
    fromMsToString(1000, 'ms'); // 1000 ms
    fromMsToString(1000, 'ss'); // 1 sec
    fromMsToString(1541, 'ss'); // 1 sec
    fromMsToString(1541, 'ss', 2); // 1.54 sec
    fromMsToString(90000, 'mm'); // 1 min
    fromMsToString(90000, 'mm', 1); // 1.5 min
    fromMsToString(5400000, 'hh'); // 1 h
    fromMsToString(5400000, 'hh', 1) // 1.5 h
    fromMsToString(5400000, 'hh:mm'); // 01:30
    fromMsToString(5400000, 'hh:mm:ss'); // 01:30:00
    fromMsToString(1802000, 'mm ss'); // 30 min 2 sec
    fromMsToString(5402000, 'hh mm ss'); // 1 h 30 min 2 sec
