How to use it

-First you will need to import the class in your project

• import {CryptoCurrency} from "currency-conversion-lib-avilamelia" -After that you will need to instanciate a variable as a new Cryptocurrency class. Exem: -const myCrypto = new CryptoCurrency(your api key) -Also you will have to pass your apikey as a parameter to the class, you dont pass, it wont work

Using the libs methods

-This library consists in two methods: conversion and quotes

• convertion: takes 3 arguments: amount:number, symbol:string, convert:string[] amount: is the amount that you want to convert symbol: Is the crypto currency that you will be converting into convert: Is the currencies like USD or BRL that you want to convert into the crypto currency value = quotes: it takes 1 argument which is an array of string: symbol:string[] -symbol: this argument is the crypto currencies that you want to know its quotes

-Now, with your variable instanciated you can use its methods. first the quotes method:

myCryptoVariable.quote(['BTC']).then((response)=>{console.log(response)})

-this code will return the following json

   response 200
    {
      "data": {
		"BTC": {
			"id": 1,
			"name": "Bitcoin",
			"symbol": "BTC",
			"slug": "bitcoin",
			"date_added": "2013-04-28T00:00:00.000Z",
			"last_updated": "2022-01-26T20:20:00.000Z",
			"quote": {
				"USD": {
					"price": 36965.522480748834,
					"last_updated": "2022-01-26T20:20:00.000Z"
				}
			}
		}
	}
  }

-The conversion method is similar, the diference is that you will need to pass 3 arguments: myCryptoVariable.conversion(25, "BTC", ["NMC"]).then((res) => console.log(res));

this code will returning the following json:

   response 200
  {
	"data": {
		"id": 1,
		"symbol": "BTC",
		"name": "Bitcoin",
		"amount": 20000,
		"last_updated": "2022-01-26T20:28:00.000Z",
		"quote": {
			"NMC": {
				"price": 500642083.02869165,
				"last_updated": "2022-01-26T20:28:00.000Z"
