I get this error when trying to start the server.

MongooseError: Can't call openUri() on an active connection with different connection strings. Make sure you aren't calling mongoose.connect() multiple times. See: https://mongoosejs.com/docs/connections.html#multiple_connections

[nodemon] app crashed - waiting for file changes before starting...

I want to implement this chat my mobile app project. Is it possible to implement in apk?

Can I publish it on playstore because that is a webapp

plss reply....thank you in advance😊😊

socket.on('private message',function(msg){
            console.log('message  :'+msg.split("#*@")[0]);
            models.messages.create({
                "message":msg.split("#*@")[1],
                "sender" :msg.split("#*@")[2],
                "reciever":msg.split("#*@")[0],
                "date" : new Date()});
            io.to(users[msg.split("#*@")[0]]).emit('private message', msg);
        });

The above msg is coming from frontend and thus anyone can impersonate anyone by changing the string they are sending from the frontend
