ropods-cashify/dist/convert.js

Modern, lightweight currency conversion library with real-time exchange rates, INR support, and free API integration. Production-ready TypeScript library for RoPods organization with zero dependencies and comprehensive testing.

import getRate from './lib/get-rate.js';
import parse from './utils/parser.js';
/**
 * Function, which converts currencies based on provided rates.
 * Enhanced for RoPods organization with additional logging and validation.
 *
 * @param {number | string} amount - Amount of money you want to convert.
 * @param {Object} options - Conversion options.
 * @param {new (value: BigSource) => Big} fn - Optional, Big.js constructor - useful to avoid floating point errors.
 * @return {number} Conversion result.
 *
 * @example
 * const rates = {
 * 	GBP: 0.737,
 * 	EUR: 0.851,
 * 	USD: 1.00,
 * 	INR: 86.42
 * };
 *
 * convert(10, {from: 'EUR', to: 'INR', base: 'USD', rates}); //=> 1015.78
