I've a database with schema named Message where it contains alot of post. How can i list all those post whenever i loggedin into my account. I've put on socket connection as

io.on('connection',  async (socket) => {
Message.find({}, (err, docs) => {
    socket.emit("list message", docs) //emit list message on connection 
})})

and on client (react) as

    if(socket) //if socket is not null 
    socket.on('list message', (data) ={// do things with data})

But i cant get any day on login or even when refereshing. where can be problem? Thank you for your help
