How do I import socket-io's client?

const cc1 = io("", {
    path: ""
});

cc1.on("HELLO", () => {
    console.log("hi")
});

cc1.on("connect", () => {
    console.log("i am here");
});

cc1.on("disconnect", () => {
    console.log("i have left");
});

cc1.on("error", () => {
    console.log("i have died");
});

cc1.io.on("reconnect", () => {
    console.log("i reconect")
});
