Firstable, I know its not good practice to share data like this in react App, But - let say "I have no choice" Now I have an issue with singleton in ReactJs. I can see that if i trying to get instance of singleton - constructor works only once. Inside constructor I have subscription to web socket which updates data inside singleton. But then Im try to reach the data from different places in app - its not update - shows me version then I took instance. How can I solve it?

export default class Manager {
    constructor(){
        this.data = null;
        socket.on('event', this.parseData)
    }

    static getInstance(){
       if (!this.instance) {
         this.instance = new QuotasManager();
       }
      return this.instance;
    }
   
   parseData(data){ ///parsedata}
   
   getData(){ return this.data}

}
