Installation
The recommended way to get started using the Node.js 2.0 driver is by using the NPM
(Node Package Manager) to install the dependency in your project.
MongoDB Driver
Given that you have created your own project using npm init
we install the mongodb driver and it's dependencies by executing the following NPM
command.
npm install mongodb --save
This will download the MongoDB driver and add a dependency entry in your package.json
file.
Troubleshooting
The MongoDB driver depends on several other packages. These are.
- mongodb-core
- bson
- kerberos
- node-gyp
The kerberos
package is a C++ extension that requires a build environment to be installed on your system. You must be able to build node.js itself to be able to compile and install the kerberos
module. Furthermore the kerberos
module requires the MIT Kerberos package to correctly compile on UNIX operating systems. Consult your UNIX operation system package manager what libraries to install.
{{% note class="important" %}} Windows already contains the SSPI API used for Kerberos authentication. However you will need to install a full compiler tool chain using visual studio C++ to correctly install the kerberos extension. {{% /note %}}
Diagnosing on UNIX
If you don’t have the build essentials it won’t build. In the case of linux you will need gcc and g++, node.js with all the headers and python. The easiest way to figure out what’s missing is by trying to build the kerberos project. You can do this by performing the following steps.
git clone https://github.com/christkv/kerberos.git
cd kerberos
npm install
If all the steps complete you have the right toolchain installed. If you get node-gyp not found you need to install it globally by doing.
npm install -g node-gyp
If correctly compiles and runs the tests you are golden. We can now try to install the mongod driver by performing the following command.
cd yourproject
npm install mongodb --save
If it still fails the next step is to examine the npm log. Rerun the command but in this case in verbose mode.
npm --loglevel verbose install mongodb
This will print out all the steps npm is performing while trying to install the module.
Diagnosing on Windows
A known compiler tool chain known to work for compiling kerberos
on windows is the following.
- Visual Studio c++ 2010 (do not use higher versions)
- Windows 7 64bit SDK
- Python 2.7 or higher
Open visual studio command prompt. Ensure node.exe is in your path and install node-gyp.
npm install -g node-gyp
Next you will have to build the project manually to test it. Use any tool you use with git and grab the repo.
git clone https://github.com/christkv/kerberos.git
cd kerberos
npm install
node-gyp rebuild
This should rebuild the driver successfully if you have everything set up correctly.
Other possible issues
Your python installation might be hosed making gyp break. I always recommend that you test your deployment environment first by trying to build node itself on the server in question as this should unearth any issues with broken packages (and there are a lot of broken packages out there).
Another thing is to ensure your user has write permission to wherever the node modules are being installed.
QuickStart
The quick start guide will show you how to setup a simple application using node.js and MongoDB. Its scope is only how to set up the driver and perform the simple crud operations. For more in depth coverage we encourage reading the tutorials.
Create the package.json file
Let's create a directory where our application will live. In our case we will put this under our projects directory.
mkdir myproject
cd myproject
Enter the following command and answer the questions to create the initial structure for your new project
npm init
Next we need to edit the generated package.json file to add the dependency for the MongoDB driver. The package.json file below is just an example and your will look different depending on how you answered the questions after entering npm init
{
"name": "myproject",
"version": "1.0.0",
"description": "My first project",
"main": "index.js",
"repository": {
"type": "git",
"url": "git://github.com/christkv/myfirstproject.git"
},
"dependencies": {
"mongodb": "~2.0"
},
"author": "Christian Kvalheim",
"license": "Apache 2.0",
"bugs": {
"url": "https://github.com/christkv/myfirstproject/issues"
},
"homepage": "https://github.com/christkv/myfirstproject"
}
Save the file and return to the shell or command prompt and use NPM to install all the dependencies.
npm install
You should see NPM download a lot of files. Once it's done you'll find all the downloaded packages under the node_modules directory.
Booting up a MongoDB Server
Let's boot up a MongoDB server instance. Download the right MongoDB version from MongoDB, open a new shell or command line and ensure the mongod command is in the shell or command line path. Now let's create a database directory (in our case under /data).
mongod --dbpath=/data --port 27017
You should see the mongod process start up and print some status information.
Connecting to MongoDB
Let's create a new app.js file that we will use to show the basic CRUD operations using the MongoDB driver.
First let's add code to connect to the server and the database myproject.
var MongoClient = require('mongodb').MongoClient
, assert = require('assert');
// Connection URL
var url = 'mongodb://localhost:27017/myproject';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
console.log("Connected correctly to server");
db.close();
});
Given that you booted up the mongod process earlier the application should connect successfully and print Connected correctly to server to the console.
Let's Add some code to show the different CRUD operations available.
Inserting a Document
Let's create a function that will insert some documents for us.
var insertDocuments = function(db, callback) {
// Get the documents collection
var collection = db.collection('documents');
// Insert some documents
collection.insertMany([
{a : 1}, {a : 2}, {a : 3}
], function(err, result) {
assert.equal(err, null);
assert.equal(3, result.result.n);
assert.equal(3, result.ops.length);
console.log("Inserted 3 documents into the document collection");
callback(result);
});
}
The insert command will return a results object that contains several fields that might be useful.
- result Contains the result document from MongoDB
- ops Contains the documents inserted with added _id fields
- connection Contains the connection used to perform the insert
Let's add call the insertDocuments command to the MongoClient.connect method callback.
var MongoClient = require('mongodb').MongoClient
, assert = require('assert');
// Connection URL
var url = 'mongodb://localhost:27017/myproject';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
console.log("Connected correctly to server");
insertDocuments(db, function() {
db.close();
});
});
We can now run the update app.js file.
node app.js
You should see the following output after running the app.js file.
Connected correctly to server
Inserted 3 documents into the document collection
Updating a document
Let's look at how to do a simple document update by adding a new field b to the document that has the field a set to 2.
var updateDocument = function(db, callback) {
// Get the documents collection
var collection = db.collection('documents');
// Update document where a is 2, set b equal to 1
collection.updateOne({ a : 2 }
, { $set: { b : 1 } }, function(err, result) {
assert.equal(err, null);
assert.equal(1, result.result.n);
console.log("Updated the document with the field a equal to 2");
callback(result);
});
}
The method will update the first document where the field a is equal to 2 by adding a new field b to the document set to 1. Let's update the callback function from MongoClient.connect to include the update method.
var MongoClient = require('mongodb').MongoClient
, assert = require('assert');
// Connection URL
var url = 'mongodb://localhost:27017/myproject';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
console.log("Connected correctly to server");
insertDocuments(db, function() {
updateDocument(db, function() {
db.close();
});
});
});
Delete a document
Next lets delete the document where the field a equals to 3.
var deleteDocument = function(db, callback) {
// Get the documents collection
var collection = db.collection('documents');
// Insert some documents
collection.deleteOne({ a : 3 }, function(err, result) {
assert.equal(err, null);
assert.equal(1, result.result.n);
console.log("Removed the document with the field a equal to 3");
callback(result);
});
}
This will delete the first document where the field a equals to 3. Let's add the method to the MongoClient .connect callback function.
var MongoClient = require('mongodb').MongoClient
, assert = require('assert');
// Connection URL
var url = 'mongodb://localhost:27017/myproject';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
console.log("Connected correctly to server");
insertDocuments(db, function() {
updateDocument(db, function() {
deleteDocument(db, function() {
db.close();
});
});
});
});
Finally let's retrieve all the documents using a simple find.
Find All Documents
We will finish up the Quickstart CRUD methods by performing a simple query that returns all the documents matching the query.
var findDocuments = function(db, callback) {
// Get the documents collection
var collection = db.collection('documents');
// Find some documents
collection.find({}).toArray(function(err, docs) {
assert.equal(err, null);
assert.equal(2, docs.length);
console.log("Found the following records");
console.dir(docs);
callback(docs);
});
}
This query will return all the documents in the documents collection. Since we deleted a document the total documents returned is 2. Finally let's add the findDocument method to the MongoClient.connect callback.
var MongoClient = require('mongodb').MongoClient
, assert = require('assert');
// Connection URL
var url = 'mongodb://localhost:27017/myproject';
// Use connect method to connect to the Server
MongoClient.connect(url, function(err, db) {
assert.equal(null, err);
console.log("Connected correctly to server");
insertDocuments(db, function() {
updateDocument(db, function() {
deleteDocument(db, function() {
findDocuments(db, function() {
db.close();
});
});
});
});
});
This concludes the QuickStart of connecting and performing some Basic operations using the MongoDB Node.js driver. For more detailed information you can look at the tutorials covering more specific topics of interest.
