Usage example

Deno module to convert fiat money currencies with initial fetched API from fixer.io There are two different modes for this module.

Mode 1) Convert Currency with Realtime Data from fixer.io (API-Key required: https://fixer.io/)

import {FiatConverter_fromAPI} from 'https://deno.land/x/currency_converter@v0.9.5/api_mod.ts'

const api_key = "12ed855902ddbea5df116639e8e3a1b2"
var amount = 100
var input_currency = "EUR"
var output_currency = "USD"

let FiatConverter = new FiatConverter_fromAPI()
var result = await FiatConverter.convert(api_key, amount, input_currency, output_currency)
console.log('Result:', result, output_currency)

Test via commandline (provided API-KEY)

deno run --allow-net "https://deno.land/x/currency_converter@v1.0.0/test_api.ts"

Output

Result: 113.25 "USD"

Mode 2) Convert Currency with Saved Data from data.json file

Step 1) Create a .json file in the same directory where you run the deno module and name it data.json

Link for the data.json file: https://deno.land/x/currency_converter@v0.8.1/data.json

Step 2) Import and create a new class

import {FiatConverter_fromJSON} from 'https://deno.land/x/currency_converter@v1.0.0/json_mod.ts'
let FiatConverter = new FiatConverter_fromJSON()

Step 3) Call the convert() method on created object

The convert() method receives four inputs:
arg0: A number of amount that should be converted into the target fiat currency
arg1: The inital currency for conversion [“EUR” –>] (ISO 3-Letter Currency Code) as string!
arg2: The target currency [–> “USD”] (ISO 3-Letter Currency Code) as string!

var result = await FiatConverter.convert(15,"EUR","RUB")
console.log(result)

Step 4) Run the module

deno run --allow-read
