            Socket.io not working when using multiple nodes through pm2
            Asked 2022-Jan-16 at 20:41

            I have NodeJS application running with Socket.io for real-time updates. I am using PM2 process manager for production Node.js application. Now I want to use cluster mode in PM2. As nodejs applications runs in single process, I want to utilize max cpu available in on my server system. Currently I have 4 cores in my system. So with PM2 cluster mode, i can utilize all cores and PM2 will handle everything on its own behind the scene.

            When using single server instance, My nodejs app with socket.io working fine with client. But when i am using cluster mode, PM2 launches 4 server instances. I tried to connect multiple client (through opening serveral terminals and running client side part on them) and they are connecting successfully with instances launched by PM2 in random manner which is expected and fine.

            What i want to do?

            1. Initiate the pm2 with cluster mode
            2. clients can connect with any of the launched instance by pm2
            3. after client connects, Server-1 will emit the events which should be sent to all the clients connected to all server
            4. After successfully testing above steps, i will integrate the logic of room, but as i am not getting success in step 3, I am not going for setp 4.

            My problem is, when i want to emit event from server-1 to clients, it should be sent to all clients connected to all 4 server instance (server-1, server-2, server-3, server-4 instances launched by PM2).

            But whenever i am emiting event from server-1, it only gets sent to clients connected to server-1 only.

            and i get error in server logs,

            Why do the major node arg parsers use chaining syntax?
            Asked 2021-Jan-21 at 18:52

            Both commander and yargs use a chaining syntax that is reminiscent of jQuery.

            Is the chaining syntax a historical outcome of the era in which the libraries were created, or is there a functional motivation?

            This approach has the name fluent interface and well-known because it simplifies making calls of a bunch of methods of the same object. The Martin Fowler mentions this approach earlier then jQuery appeared. See Fluent interface

            For instance look at LINQ in C# as a powerful implementation of a fluent interface principle.

            In Node.js, process.argv is an array containing the command line arguments passed when the Node.js process was launched. So, program.parse(process.argv) parses the the command line options for arguments, which is bypassing your inquierer.js prompt. You can leave it out.

            When you run your npm run command you need to utilize the special -- option to demarcate the end of any option(s) that may belong to the npm run command itself (e.g. --silent), and the beginning of the argument(s) that are to be passed to the end of the npm script.

            Run the following command instead:
