Ideas for effectively reusing MongoDB Mongoose queries in Node.js

Can you re-use an existing exec mongodb/mongoose query in nodejs?

For example, let's say I create a query like this to check if a user exists:

const inviter = await User.findOne({ _id: req.userData._id }).exec()
// There is more code below before updating the user data

Basically, if I want to update the data, I have to write the same code again and add an update function like this:

User.findOneAndUpdate({ _id: req.userData._id }, { $push: { invited: recipient.value } }, { useFindAndModify: false })

Is it possible to continue the first query and add a short query to update based on the result of the first query, for example like this:

inviter.update({ $push: { invited: recipient.value }).exec()

I understand that this code may not work as intended...

Answer №1

Here's a potential solution you can implement:

 User.findOne({ _id: req.userData._id }).exec((err, result) => {
            if(result)
            {
             result.invited =  recipient.value;
             result.save((err) => {
              if (err) // handle error
             });
            }
           

        })
    }
