I have socket.io connection, I want to pass the original instance to other components. I am using Typescript React. It gives me error like:
Type '{ socket: Socket<DefaultEventsMap, DefaultEventsMap>; }' is not assignable to type 'IntrinsicAttributes'.
Property 'socket' does not exist on type 'IntrinsicAttributes'.ts(2322)
My code: main.tsx
import React from "react";
import ReactDOM from "react-dom/client";
import App from "./App";
import "./index.css";
import { io } from "socket.io-client";
const socket = io("http://localhost:8081");
ReactDOM.createRoot(document.getElementById("root")!).render(
<React.StrictMode>
<App socket={socket}/> //getting error from socket
</React.StrictMode>
);
I would create a wrapper around the socket, something like this (the code is in typescript):
// Singleton
class MySocket {
public socket:Socket;
public static instance: MySocket = new MySocket();
private constructor() {
socket = io("http://localhost:8081");
}
public doSomething(){
//...
}
public doOtherThings(){
//...
}
}
Then I would use it like this:
// Component A
const ComponentA = () => {
useEffect(()=>{
MySocket.instance.doSomething();
},[]);
}
export default ComponentA
// Component B
const ComponentB = () => {
useEffect(()=>{
MySocket.instance.doOtherThings();
},[]);
}
export default ComponentB
But, with your approach I think you can go this way:
interface Props {
socket: Socket<DefaultEventsMap, DefaultEventsMap>
}
const App = (props:Props)=>{
}
and you should be able to pass the socket instance you are creating it in the main.tsx to the App component.
