Managing countries and currencies with JS
- The npm country-currency-utils package allows developers to manage a list of over 200 countries and corresponding currencies without storing them within their codebase.
- Country-specific data, including country name, dial code, currency code, and flag emojis, among other details, can be accessed through different functions of the package such as getAllCountryDetails(), getAllCountryData(), and getCountryData(countryCode: string).
- Similarly, the package also provides information on currency codes, currency symbols, digit grouping, and decimal precision.
- The package also has utility functions to handle monetary amounts such as rounding and formatting. These include getRoundedAmount(), getFormattedAmountOnCurrency(), and getDisplayAmountOnCurrency().
- getRoundedAmount() can be used to round a monetary amount either up or down. The method getRoundedAmountOnCurrency() adjusts the rounding to suit the currency.
- The function getFormattedAmountOnCurrency() retrieves the amount with fixed decimal places and comma-separated values. getDisplayAmountOnCurrency() adds the currency symbol to properly formatted amounts.
- If the function getDisplayAmountOnCurrencyCode() is used instead of getDisplayAmountOnCurrency, it provides a promise which accepts only the currency symbol.
- The country-currency-utils package offers promises to fetch country and currency data from a CDN, instead of carrying lists of the data into the codebase.
- The package can help reduce the complexity of managing currencies in projects with clients in multiple countries.
- Developers can find the package useful in making monetary amount displays more uniform across diverse client bases.
