100% Asynchronous

NodeOPCUA takes advantage of the asynchronous nature of node.js, creating highly responsive applications.

import OPCUAServer from "node-opcua";

const server = new OPCUAServer({});
await server.start();

console.log("Server is now listening ... ( press CTRL+C to stop) ");
await new Promise((resolve) => process.once("SIGINT",resolve));

await server.shutdown();
