How to insert array of document in mongodb using node.js? - arrays

Question

I want to insert array of document to mongodb using node.js but while inserting it's only inserting first data only.
[{
"userid": "5664",
"name": "Zero 2679",
"number": "1234562679",
"status": "contact",
"currentUserid": "Abcd"
},
{
"userid": "5665",
"name": "Zero 3649",
"number": "1234563649",
"status": "contact",
"currentUserid": "Xyz"
}]
Sample code
collection.insert([{"userid": userid,"name": name,"number": number,"status": status,"currentUserid": currentUserid}], function(err, docs) {
if (err) {
res.json({error : "database error"});
}else {
collection.find({currentUserid:currentUserid}).toArray(function(err, users) {
res.send(users);
});
}});
But it still inserting first value only can you please tell me how to insert all these documents.
Please kindly go through my post and suggest me some solution.

Answer 1

In your sample code you are adding only 1 user.
db.collection('myCollection').insert([doc1, doc2]); inserts two documents using bulk write.
See documentation here: https://docs.mongodb.org/manual/reference/method/db.collection.insert/
From your sample, you can do:
var data = [{
"userid": "5664",
"name": "Zero 2679",
"number": "1234562679",
"status": "contact",
"currentUserid": "Abcd"
},
{
"userid": "5665",
"name": "Zero 3649",
"number": "1234563649",
"status": "contact",
"currentUserid": "Xyz"
}];
db.collection('myCollection').insert(data)
.then(function() {
return db.collection('myCollection').find({number: {$in: ["1234563649", "1234562679"]}});
})
.then(function(res) {
console.log(res);
});
