remove _id from mongo result
Try this solution:
app.get('/itesms', function(req, res) {
items.find({}, { _id: 0 }).toArray(function (err, array) {
res.send(array);
})
});
The usual .find({}, {_id:0})
approach wasn't working for me, so I went hunting and found in another SO answer that in version 3 of the Mongo API, you need to write it like this: .find({}, {projection:{_id:0}})
. So, for example:
let docs = await db.collection("mycol").find({}, {projection:{_id:0}}).toArray();
It seems that (in the nodejs API, at least) you can also write it like this:
let docs = await db.collection("mycol").find({}).project({_id:0}).toArray();
