Web Development with MongoDB and Node.js

Chapter 2. Getting Up and Running

The first thing you need to take care of is to make sure your development environment is equipped with the necessary requirements in order for you to use both Node and MongoDB while launching the apps you write.

In this chapter, we will cover the following topics:

  • Installing and testing Node.js
  • Installing, configuring, and testing MongoDB
  • Writing and launching a simple app

Environment assumptions and requirements

For the remainder of this book, I will assume that you are using either a Mac with OS X, Linux, or Windows 7 or 8. You will also need superuser and/or administrator privileges on the computer, as you will be installing the Node and MongoDB server software. The code and examples after this chapter will all be OS agnostic and should work in any environment, assuming you have taken the steps I outline here so that you are prepared ahead of time.

You will need a good text editor to write and edit the code. Any editor of your liking will do. Personally, I am a huge fan of Sublime Text 3 (http://sublimetext.com). It is a simple, lightweight editor that has great color-coding syntax support. However, its true power comes from the unlimited plugins made available by other developers. There is literally a plugin for everything in Sublime! VI and Notepad are also good options if you want to stay super lightweight.

Finally, you're going to need access to...

Installing Node.js

Node.js can be easily installed by visiting the official Node website and accessing the Downloads section at http://nodejs.org/download/.

Once there, be sure to download the correct version depending on your OS and CPU (32 bit or 64 bit).

Mac OS X installation instructions

To determine which version of Node you want to download, you first need to determine your processor type: 32 or 64 bit. You can do this by executing the following command from a terminal:

$ sysctl hw | grep 64bit
hw.cpu64bit_capable: 1

If you get 1 in the response, then you are running a 64-bit CPU. If the response is 0, then you are running the 32-bit version. Fortunately, there is a universal installer specifically for Mac available from the Node website; however, if you wanted to download the binary, at least now you know which to get.

Once the download is complete, double-click on the .pkg file, which will launch the Node installer (as shown in the following screenshot):

Mac OS X installation instructions

Proceeding through each step of...

Installing the MongoDB server

MongoDB can also be easily downloaded by visiting the official MongoDB website and accessing the Downloads section at http://www.mongodb.org/downloads.

Note

Depending on the version of MongoDB you downloaded, you will want to replace <version> in the following sections with the appropriate version number that matches your file.

Once there, be sure to download the correct version depending on your OS and CPU (32 or 64 bit). You should have determined this in the previous steps when you downloaded and installed Node. For Windows users, you can opt to download the MSI installer file, which will make installation much simpler.

Mac OS X installation instructions

After completing the download, open and extract the contents of the .tgz file. You will want to move the extracted contents to a /mongodb destination folder. You can do this either via the Finder or the command line, whichever you prefer.

Note

Alternatively, MongoDB can be very easily installed using Homebrew...

Writing your first app

Now that you have everything installed and confirmed that it's all working, you can write your first quick app that will use both Node and MongoDB. This will prove that your environment is good to go, and you're ready to get started. In addition, it will give you a brief taste of the world of Node and MongoDB development! Don't worry if a lot of the following is confusing or just doesn't make sense to you—it will all be made clear throughout the rest of the book!

Step one is to create a folder that you can work from while creating files and installing Node modules. From your home or development folder, execute the following commands:

$ mkdir testapp
$ cd testapp

The code

The first thing you need to do before you write any code is download any modules you plan to use with your app from npm. Since this is a basic app, you'll only need to use the MongoDB Node driver. You can easily install this by executing the following command:

(term_1)...

Summary

In this chapter, we took time to make sure your development environment was properly configured with both the Node runtime environment as well as the MongoDB server. After making sure both were properly installed, we wrote a basic app that utilized both technologies.

The app connected to a locally running MongoDB server, checked for the existence of a specific set of data, and if it wasn't found, sample records were inserted automatically. It then retrieved those same records and displayed them to the screen, which were sorted alphabetically.

Now that the tedious but necessary tasks of set up and installation are out of the way, we can move on to some fun and get started with learning! In the next chapter, we will review a primer on the JavaScript language and understand the basics of Node. Then, we will review basic Create, Read, Update, Delete (CRUD) operations with MongoDB using the mongo shell.

I am not a professional coder or programmer. My job is health related. I code as a hobby. This book is what you need to get into development with Mongo and Nodejs. The example application inside the book will form a nice real time app also. The concepts are very well explained without boring you. Even a person like me can understand and code everything.

Writing RESTful services in Nodejs can be as simple as glueing modules. Internet is plenty of Node.js middleware. To achieve so, you first need to learn the basics.It's better to have some previous knowledge of Javascript before reading this book as Web Development with MongoDB and Node.js has a tiny introduction to Javascript and Node.js.The book explains how to scaffold web applications through full coded examples. Middleware is the key of being highly productive and the book uses and explains the most well-known modules. You'll find out a big example split into several chapters that is a clone of a popular social image-sharing site that will show you things such as:Express: handle routing, middleware injection, ...Connect: a suite of middleware for multiple things. In the book Connect is used to deal with json, cookies, logging, parsing, encoding, HTTP method support, handling errors ...Handlebars: apart from explaining the basics of this template engine, it also shows how to build html layouts, partial views which prevent code duplication and helpers used for injecting functions at the time of rendering.And all this is wired up with MongoDB which is a NoSQL database. You'll learn the really basics of CRUD operations over Mongo (Create, Retrieve, Update and Delete). But Mongo is such simple that it really doesn't need further explanation other than seeing the API definition. This makes the book swift and faster to read. As it's already a tradition with Mongo and Javascript, it also involves Mongoose. Mongoose introduces schemas and models, that is to say built-in types, field restrictions and validation.The book culminates with four miscellaneous chapters. A chapter dedicated to testing using Behavior Driven Development (Mocha, Chai.js, Sinon.js, Proxyquire). Another chapter that gathers some web services (like Heroku, Amazon, Digital Ocean, Nodejitsu and Microsoft Azure) and tells how to deploy your nodejs web-apps. And finally, the last two chapters reviews front-end frameworks like: Backbone.js, Ember.js, Angular.js; and Node.js frameworks like Meteor, Sails, hapi, Koa or Flatiron.At the end of the book you will be more likely to start developing your own RESTful services as Node.js makes things simple and this book covers really common problems.You can get your copy of Web Development with MongoDB and Node.js right here!

Jason is a MEAN expert! Great real world examples and spoken in a language that anyone can understand. Highly recommend this book to anyone who is spiking the Mongo/Express/Angular/Node stack to build engaging single page apps in JS.

This book contains hands-on instructions for getting started with development of complete interactive Web sites using up-to-day Web technologies. It empowers readers with practical knowledge of Node.js and MongoDB. The first chapter describes new concepts of Web development, which were introduced with Node.js. From chapter 4, Writing an Express.js Server, we are guided to create a sample Web application, which includes all main functionality of real-world applications, based on the usage of Express.js Web framework. Chapter 9, Testing Your Code, introduces the tools and techniques to write automated tests for Node.js code. Chapter 10, Deploying with Cloud-based Services, provides detailed instructions for Cloud-based deployment and hosting of Web applications. In chapter 12, Popular Node.js Web Frameworks, author reviews other Web frameworks, including recently-emerged ones, and analyzes their advantages, drawbacks and cases of usage. The book is written by clear and concise language. The content includes a lot of code fragments, schemes, and screenshots. Each chapter ends with Summary section, which recapitulates all the main topics of the chapter. There are several reminder sections, like A JavaScript Primer, which recalls JavaScript basics, or What is an API, which discusses API development concepts. All chapters include links to additional information resources. For all main technologies being discussed, detailed step-by-step installation instructions are provided for Windows, Mac OS, and Linux environment, which greatly stimulate readers to download and try all the stuff. I think that this book can be useful for all Web developers, who want to use modern technologies for creating powerful and scalable Web applications.

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
