NFJS (NumberFormatter JS)
Introduction
A fast number formatter with no external libraries
Usage
const {
formatFromPattern,
formatFromConfig,
parsePattern,
} = require("number-formatter-js");
formatFromPattern(1000000, "$0,000.00"); // "$1,000,000.00"
formatFromPattern(1000000, "$+0,000.00"); // "$+1,000,000.00"
formatFromPattern(-1000000, "$+0,000.00"); // "$-1,000,000.00"
formatFromPattern(1000000, "+++-> +0,000.00USD"); // "+++-> +1,000,000.00USD"
// Recommended usage for using the same pattern more than one time
// To avoid re-parsing the pattern
let config = parsePattern("+++-> +0,000.00USD");
formatFromConfig(-1000000, config); // +++-> -1,000,000.00USD
formatFromConfig(1000000, config); // +++-> +1,000,000.00USD
// Customize the separator
formatFromPattern(1000000, "+++-> +0,000.00USD", { separator: "'" }); // "+++-> +1'000'000.00USD"Demo

Format Guid
| Description | Symbol | Summary |
|---|---|---|
| Zero | 0 | Defines digits cannot be used in the prefix/suffix |
| Separator | , | Defines a separation for example 0,00 -> Separate by 2 digits. 0,000 -> Separate by 3 digits. |
| Decimal Point | . | Show Decimal Numbers for example 0.00 -> Shows 2 decimal digits. 0,00.000-> Shows 2 decimal digits and separates by 2 digits |
| Signs | +/- | Must be used right before the number mask/pattern with no white space in between for example: +0,00.000, -0,00.000 AND NOT + 0,00.000, - 0,00.000 (the sign here will be counted as a prefix) Signs could be used in the suffix and prefix |
| Suffix/Prefix | Anything that is not a zero outside the mask/pattern for example +$(-0,00.00) -> Prefix = +$( Suffix = ) Pattern= -0,00.00 So the number 12345 will result -> +$(1,23,45.00) |
Notes
- If you want to use Zeros in the prefix you should change the PatternConfig for example:
let config = parsePattern("+0,000.000$");
config.prefix = "(000)";
formatFromConfig(1000, config); // output: (000)1,000.000$Installation
