How to implement currency conversion?

Question

JavaScript

Good day.
I need to implement multi-currency on a store website. There is a currency selection field. All prices in the store are in euros.
What tool to use? Where to get exchange rates from? And other recommendations)
I would be very grateful for the help.

Answer 1

It is better to take courses from where you take them when making calculations. From your bank for example.
As for the rest, I don't see the problem. You can recalculate currencies at least in JS on the event of a change in the current currency by the user.

Answer 2

Create a "currency" model, and in the product model add the function of multiplying the price by the exchange rate!!!
