The SDK can be used in any frontend application, regardless of the framework used (react, Angular, Vue, etc.), or in a JavaScript application that does not use the framework at all. You can also use the SDK to calculate the trade on the NodeJS server; however, it will be impossible to conduct a transaction on the server on behalf of the user. In the future, we’re planning to develop a module for a more complete SDK integration on the server, as well as specialized modules for specific frontend frameworks for even faster SDK integrations.
