I am using nodejs as backend and mongodb. So I query using the email and get a array of data and how to use that data.

User.find({email: ""}, (err,response) =>{
--
--
});

Here I get data

{
  email: "..",
  name: "..",
  friend: "..",
}

So can I use response.email to get email, and response.name to get name?

CodePudding user response：

If the response is array use response[index].name or if email is unique in that collection you can use User.findOne(), it will return single object as response, Where you can access object properties directly.

There are 2 cases. Chose whatever suits your situation

1. If email is unique

   // use findOne (it will return only single object)
   User.findOne({ email: "[email protected]" }, (err, response) => {
       if (err)
           throw new Error(err);
   
       if (response) // to check if something is returned or not
           console.log(response.name);  // you can get any value from response.yourRequiredField or console.log(response) for full object
       else
           console.log("Nothing in response");
   });
   

2. If email is not unique

    // use find (this will return array of matching objects)
    User.find({ email: "[email protected]" }, (err, response) => {
        if (err)
            throw new Error(err);
   
        if (response.length > 0) // to check if something is returned or not
            console.log(response[0].name); // you need to use index here OR console.log(response) for full array OR console.log(response[0]) for full object at given index
        else
            console.log("No matching object in response");
    });
