API wrapper (written in V) for https://api.exchangeratesapi.io/
Use:
v install mehtaarn000.vcurrency
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).
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)
}
