Add Data to MongoDB

On this page

Overview
    Data Model
    Snippet Setup
Methods
    Insert a Single Document
    Insert One or More Documents

Overview

The code snippets on this page demonstrate how to insert one or more documents into a MongoDB collection. Insert operations take the documents to add to MongoDB as an argument and return documents that describe the results of the operation.
Data Model

The examples on this page use a collection named store.items that models various items available for purchase in an online store. Each item has a name, an inventory quantity, and an array of customer reviews.

// store.items
{
_id: ,
name: ,
quantity: ,
reviews: [ { username: , comment: } ]
}

Snippet Setup

Functions JavaScript SDK Android SDK iOS SDK 

To use a code snippet in a function, you must first instantiate a MongoDB collection handle:

exports = function() {
const mongodb = context.services.get(“mongodb-atlas”);
const itemsCollection = mongodb.db(“store”).collection(“items”);
const purchasesCollection = mongodb.db(“store”).collection(“purchases”);
}

Methods
Insert a Single Document

You can insert a single document using the collection.insertOne() action.

The following snippet inserts a single item document into the items collection:

Functions JavaScript SDK Android SDK iOS SDK 

const newItem = {
“name”: “Plastic Bricks”,
“quantity”: 10,
“category”: “toys”,
“reviews”: [{ “username”: “legolover”, “comment”: “These are awesome!” }]
};

itemsCollection.insertOne(newItem)
.then(result => console.log(Successfully inserted item with _id: ${result.insertedId}))
.catch(err => console.error(Failed to insert item: ${err}))

Insert One or More Documents

You can insert multiple documents at the same time using the collection.insertMany() action.

The following snippet inserts multiple item documents into the items collection:

Functions JavaScript SDK Android SDK iOS SDK 

const doc1 = { “name”: “basketball”, “category”: “sports”, “quantity”: 20, “reviews”: [] };
const doc2 = { “name”: “football”, “category”: “sports”, “quantity”: 30, “reviews”: [] };

return itemsCollection.insertMany([doc1, doc2])
.then(result => {
console.log(Successfully inserted ${result.insertedIds.length} items!);
return result
})
.catch(err => console.error(Failed to insert documents: ${err}))
