Socket.io custom client ID

Question

I\'m making a chat app with socket.io, and I\'d like to use my custom client id, instead of the default ones (8411473621394412707, 1120516437992682114

Answer 1

why not a simpler solution that does not need to maintain an array of connected clients and does not override internal socket id?

io.on("connection", (socket) => {
    socket.on('storeClientInfo', (data) => {
        console.log("connected custom id:", data.customId);
        socket.customId = data.customId;
    });

    socket.on("disconnect", () => {
        console.log("disconnected custom id:", socket.customId);
    })
});

Client side

let customId = "your_custom_device_id";
socket.on("connect", () => {
    socket.emit('storeClientInfo', { customId: customId });
});
