使用nodejs作为Websocket服务器的客户端。 还是事件驱动的

Question

I would like to code a performance test creating hundreds of concurrent websocket connections to a vendor's server, that will randomly send/receive messages and then hangup.

Can I use Websockets with nodejs to do this and will this be considered event driven?

To be clear, I am not building a websocket server. I basically want to use nodejs as a client to connect to an outside websocket server but create hundreds of concurrent connections that it will respond to.

Thanks.

Yes you can use node.js and yes it will be event driven. All network I/O in node.js is exclusively asynchronous and event-driven.

Be aware substack's rant in the hyperquest README about node.js core http module's connection pooling, which you will want to make sure you bypass. Presumably you'll be using a helper library such as socket.io or sock.js. Just check that they will create the number of connections you want to a single server without any pooling or throttling.
