Sometimes, we want to create a secure (TLS/SSL) Websocket server with Node.js
In this article, we’ll look at how to create a secure (TLS/SSL) Websocket server with Node.js.
How to create a secure (TLS/SSL) Websocket server with Node.js?
To create a secure (TLS/SSL) Websocket server with Node.js, we can use the https module.
For instance, we write
const WebSocket = require("ws").Server;
const { createServer } = require("https");
const fs = require("fs");
const server = createServer({
cert: fs.readFileSync(config.sslCertPpath),
key: fs.readFileSync(config.ssKeyPpath),
});
const socket = new WebSocket({
server,
});
socket.on(() => {
//...
});
server.listen(config.port);
to call createServer to create a HTTPS server with the cert and key certificate and key files.
Then we use the WebSocket constructor to create a WebSocket server from the HTTPS server.
Next, we call socket.on to listen for communication.
And we call server.listen to start the server.
Conclusion
To create a secure (TLS/SSL) Websocket server with Node.js, we can use the https module.
