db.get().collection("product").insertOne(product,(err,data)=>{
console.log(data);
})
result
{
acknowledged: true,
insertedId: new ObjectId("615c620b5fccd83152f4ad2f")
}
How do I get the id from the new ObjectId?
You can get the new ObjectId like that:
db.get().collection("product").insertOne(product).then(data => data.insertedId);
In short just use:
data.insertedId
As you found out return object is
acknowledged: true, insertedId: new ObjectId("615c620b5fccd83152f4ad2f")
here insertedId is what you you need.But it is not not returned as a string value. So to convert it into string by using
data.insertedId.toString()
this will return _id in string type
