React background management system websocket realizes real-time status update

A project under development, based on the ant admin open source project, now has a requirement to establish a socket connection with the backend to automatically update the task status. I have no previous development experience in this area. The project is now a http connection. According to the return of the background, the subcomponent is passed to the sub-component through parameters to show that the sub-component is a list of ant design, and the requirement should be changed to the backend active push task status. So the question is: how do I rewrite this piece?

this.socket.close();

because I use socket.io, at the back end, I don't know if there is a match between the two socket.io-client,. The general idea is this
