mongo db with promise(async).
                  
                  
                  mongoose
                  
                  
                      .connect("mongodb://127.0.0.1:27017/shopping", { useNewUrlParser: true })
                  
                  
                      .then(res => {
                  
                  
                        logger.info("Connected to MongoDB");
                  
                  
                      });
                  
                  
                      
                  
                  
                  }In the main entry script, I have session setting like below executed before connecting to mongo
                  
                  
                  
                  
                  
                  app.use(
                  
                  
                    session({
                  
                  
                      secret: "43jkfd5kjG90",
                  
                  
                      resave: false,
                  
                  
                      saveUninitialized: false,
                  
                  
                      store: new MongoStore({ mongooseConnection: mongoose.connection })
                  
                  
                    })
                  
                  
                  );Is it OK? I do not have any problem with it.
                  
                  
                  Is it suitable to apply sync connection and after connecting to db I run other lines (commands)?
