common-formatters

Common string formatters.

Motivation

There's no such thing as universal formatters collection, but ... Ha, and this one library is just a set of several controversial workarounds. What can be said in defense? Smaller is better.

Usage examples

    import {formatMoney, formatNumber, formatCardPan, formatPhone, formatPercent} from '@qiwi/common-formatters'

    formatMoney(12300.45, {currencyCode: 'RUB', fractionDelimiter: '.'}) // '12 300.45 ₽'
    formatMoney(123.45, {currencySymbol: 'Foo'}) // '123,45 Foo'

Phone numbers

• E.164
• Formatting International Phone Numbers

    // Basic cases
    formatPhone('1234567')     // 123-45-67

    formatPhone('12345')       // 1-23-45
    formatPhone('1234567890')  // 1234567890
    
    // Format by mask
    formatPhone('79876543210', {mask: '+* *** ***-**-**'}) // +7 987 654-32-10
    
    // Format by opts
    formatPhone('223344', {countryCode: '7', areaCode: '8443', areaBrackets: true, phoneNumberDelimiter: '_'}) // +7 (8443) 22_33_44
