vcurrency

API wrapper (written in V) for https://api.exchangeratesapi.io/

Installation

Use:

v install mehtaarn000.vcurrency

Functions

The get_data function takes two arguments: options (type map) and symbols (type array of strings).

get_data takes arguments: start_date, end_date (which can both be an empty string to get latest data), and base (default "EUR").

The symbols array should have all the symbols that you would like to get from the API. For example, "USD", "INR", "NZD" (default is all symbols).

Example usage

Get raw JSON from the API (not reccommended):

module main

import mehtaarn000.vcurrency

fn main() {
    data := vcurrency.get_data(map{"start_date" : "2021-02-25", "end_date" : "2021-02-26", "base" : "INR"}, ["USD", "CNY"])
    
    // To get the response
    println(data.json)

    // To parse the json data
    println(data.json["rates"])

    // To get the generated url
    println(data.url)

}

Use the convert function: convert takes three arguments. base (type string), amount (type f64), and symbols (type []string). It returns a map[string]f64.

module main

import mehtaarn000.vcurrency

fn main() {
    data := vcurrency.convert("USD", 100, ["EUR", "INR"])
    println(data)
}

Or, Use the convert_on_date function to convert a value based on the given date: convert_on_date takes four arguments base (type string), date (type string in YYYY-MM-DD), amount (type f64), and symbols (type []string). It returns a map[string]f64.

module main

import mehtaarn000.vcurrency

fn main() {
    data := vcurrency.convert_on_date("USD", "2020-01-05", 100, ["EUR", "INR", "CZK"])
    println(data)
}
