elemental-string-format
Advanced tools
Can be used standalone, though this library was developed to add missing functionality into the (Elemental Low-code platform)[https://elementalsystem.org].
This library provides the ability to format strings in the same way as String.Format in .NET.
Basic usage:
const stringFormat = require("elemental-string-format");
process.env.LANG = 'en_GB';
console.log(
[
// general
stringFormat("{0} {1}: {0}", "The", "first value is"), // positional arguments - The first value is: The
stringFormat("{0,-10}", "padded"), // left padded alignment - padded
stringFormat("{0,10}hello", "world"), // right padded alignment - world hello
// numbers
stringFormat("{0:c}", 3.14), // currency, supports decimal places {0:c4} - £3.14
stringFormat("{0:f4}", 1.23456), // fixed point, defaults to 6 places if no arg given - 1.2346
stringFormat("{0:d4}", 12), // zero padded number - 0012
stringFormat("{0:e2}", -1052.0329112756), // exponential - -1.05e+003
stringFormat("{0:G4}", 123.4546), // general number format - 123.5
stringFormat("{0:N}", 1234567890), // human natural - 1,234,567,890.00
stringFormat("{0:P}", 0.12), // percentage - 12%
stringFormat("{0:R}", 1.23), // round trip number - 1.23
stringFormat("{0:x4}", 255), // hexadecimal - 00ff
// dates/times
stringFormat("{0:d}", new Date()), // short date format - 20/01/2020 UK, 1/20/2020 USA
stringFormat("{0:D}", new Date()), // long date format - Wednesday, January 1, 2020
stringFormat("{0:f}", new Date()), // full date short time - Wednesday, January 1, 2020 1:34 PM
stringFormat("{0:F}", new Date()), // full date long time - Wednesday, January 1, 20202 1:34:45 PM
stringFormat("{0:Y}", new Date()), // year month - January 2020
stringFormat("{0:M}", new Date()), // day month - January 1
stringFormat("{0:u}", new Date()), // universal sortable - 01-01-2020 13:34:45Z
stringFormat("{0:t}", new Date()), // short time - 1:34 PM
stringFormat("{0:T}", new Date()), // long time - 1:34:45 PM
stringFormat("{0:R}", new Date()), // RFC1123 - Wed, 1 Jan 2020 13:34:45
stringFormat("{0:O}", new Date()), // round trip
stringFormat("{0:g}", new Date()), // general short time - 20/01/2020 1:34 PM
