NodeOPCUA takes advantage of the asynchronous nature of node.js, creating highly responsive applications.
const { OPCUAServer } = require("node-opcua");
(async () => {
const server = new OPCUAServer({});
await server.initialize();
await server.start();
})();
NodeOPCUA has been developed using TDD and benefits from more than 2500 unit tests and 90% code coverage.
NodeOPCUA uses Travis as a continuous integration service.
NodeOPCUA can be use in Javascript as well as in Typescript.
NodeOPCUA is free for commercial use. Check out the license.
