Question

In node.js I’d like to create a client that:

• open a socket to “server1”
• through this socket: send info (array of bytes) to “server1” (this will activate a module on server side that will send data to client on irregular basis)
• read data sent by “server1”

Can I only use a socket that is created when my client startup and then wait for data from server1 or do I need to implement a server instead ?

Answer 1

var net = require("net");

var client = net.createConnection(port, host);

client.on("connect", sendInfo);

client.on("data", readData);

client.on("end", cleanUp);

Just create a TCP connection to your server. Then just do stuff with it.
