How to get only required data fields from mongoDB

If you are looking for a solution to get only the required fields data from mongoDB, this simple solution can help you without any side effect

Say, you have this data fields in your database

        meetingId,
        meetingDate,
        noticeDate,
        title,
        agenda,
        venue,
        notice,
        noticeDistribution,
        chairedBy,
        participants,
        minutes,
        minutesPreparedBy,
        minutesApprovedBy,
        minutesDistribuion,
        status,
        username,
        userid

But you need to send only minutes and minutesApprovedBy fields, then you can go this way,

yourDB.find({}, {minutes:true, minutesApprovedBy:true})
.then(data=>res.send(data))
.catch(err=>res.send(err))

The field you need, put together with a value to true as shown above. This will return only those fields (filter) from the database. You can also use findOne({}, {}) where necessary.
