Mongo Find() function won't exclude _id

Question

Hello I can\'t seem to get the exclude _id to work, here is the code

const findLabels = (db, cb) => {
  // Get the documents collection
  const collection         


        

Answer 1

I think the correct way to specify a projection is to use the "fields" or "projection" property, depends on the version of your driver.

collection.find({}, {projection:{ _id: 0 }})

Read documentation here.

Answer 2

if you use findOne,

you can try

    const posts : Collection= db.collection('posts')
    let document = await posts.findOne({
            path: path
        }, {
            fields: {
                _id: 0
        }
    })

In example, I query path(used as _id)
