react-native-currency-formatter

library1.0.3jsnpmunverified

A lightweight React Native library for formatting currency values as IDR (Indonesian Rupiah) and USD (US Dollar). Current stable version is 1.0.3, updated infrequently (last commit in 2019). Key differentiators: simple API, automatic rounding of IDR values to nearest integer, and configurable decimal/thousand separators. However, it lacks modern ESM support, TypeScript definitions, and active maintenance. Alternatives like 'react-native-currency-input' offer more features and active development.

CurrencyFormatter

✓ import CurrencyFormatter from 'react-native-currency-formatter';

✗ const CurrencyFormatter = require('react-native-currency-formatter');

Default export; CommonJS require also works but not recommended for newer React Native projects.

Basic usage of CurrencyFormatter to format a number as IDR or USD based on configuration in the source file (default: IDR with left position).

import React from 'react'; import { Text, View } from 'react-native'; import CurrencyFormatter from 'react-native-currency-formatter'; export default function App() { const value = 1234511.47; const formatted = CurrencyFormatter(value); return ( <View> <Text>{formatted}</Text> </View> ); }

Debug

Known issues

deprecatedPackage not updated since 2019; may not work with latest React Native versions.

fix

Consider migrating to a maintained alternative like 'react-native-currency-input' or use Intl.NumberFormat.

affects: *

gotchaThe library does not export any types; TypeScript users will need to declare a module or cast to 'any'.

fix

Add a type declaration: declare module 'react-native-currency-formatter';

affects: *

gotchaFormatting is hardcoded to IDR or USD via source code modification; no runtime configuration API.

fix

Edit node_modules/react-native-currency-formatter/index.js to change currency settings, then use patch-package to persist changes.

affects: *

gotchaThe library only supports IDR and USD; attempting to use other currencies will not work without source modification.

fix

If other currencies needed, switch to a more flexible library like 'intl' or 'currency.js'.

affects: *

deprecatedNo CommonJS or UMD build; requires React Native Metro bundler.

fix

Ensure you are using a React Native environment; not suitable for plain React web apps.

Errors

Common errors & fixes

TypeError: CurrencyFormatter is not a function

Using named import instead of default import.

fix

Change import to: import CurrencyFormatter from 'react-native-currency-formatter';

Invalid currency code provided.

Attempting to set currencyCode to a value other than 'IDR ' or 'USD ' with trailing space in source file.

fix

In node_modules/react-native-currency-formatter/index.js, set currencyCode to 'IDR ' (note trailing space) or 'USD '.

Cannot read property 'format' of undefined

Using the library outside of React Native environment (e.g., Node.js or browser without polyfill).

fix

Ensure the code runs in React Native; or provide a polyfill for Number.prototype.toLocaleString if in other environment.
