Learning Node.js for .NET Developers

Chapter 2. Getting Started with Node.js

This chapter will get you up and running with Node.js. You'll see how quick this can be and how easy it is to start writing web applications. You'll also choose a development environment for working with Node.js. In this chapter, we will cover the following topics:

  • Installing Node.js
  • Writing our first Node.js web application
  • Setting up our development environment

Installing and running Node.js

To install Node.js, visit https://nodejs.org, and download and run the installer package for the currently recommended version. The examples in this book are based on Node.js v6, released in April 2016 and supported through to April 2018.

After installation, open up a console window (run command prompt on Windows, or terminal on Mac) and type node.

This opens the Node.js REPL, which works like the JavaScript console in browsers. Try typing in a few commands and see the output:

> function square(x) { return x*x; }
undefined
> square(42)
1764
> new Date()
2016-05-02T16:08:41.915Z
> var foo = { bar: 'baz' }
undefined
> typeof foo
'object'
> foo.bar
'baz'

Now let's make use of one of the Node.js-specific APIs to create an HTTP server. Type the following commands into the REPL (the output of each command is omitted from the listing below for brevity):

> var listener = function(request, response) { response.end...

Choosing an editor

Of course, we're not going to write all of our code inside the REPL. You can use any text editor or IDE you like for writing JavaScript for Node.js. If you're not sure what to use, try one of the following:

These are both free, lightweight IDEs that are actually implemented in Node.js. They are both available for Windows, Mac, and Linux.

The code listings in the rest of this book will be JavaScript source code files, not commands to be typed into the REPL.

Using an application framework

The server we created in the REPL used the low-level HTTP module built into Node.js. This provides an API for creating a server that reads data from requests and writes to responses.

As with other programming platforms, there are frameworks available providing more useful high-level abstractions for writing web applications. These include things such as URL routing and templating engines. ASP.NET MVC, Ruby on Rails, and Spring MVC are all examples of such frameworks on different platforms.

Note

Example code

If you get stuck at any point in this book, you can follow along with the code at https://github.com/NodeJsForDevelopers (there is a repository for each chapter and a commit for each heading that introduces any new code).

In this book, we'll be using a framework called Express to write a web application in Node.js. Express is the most popular web application framework for Node.js. It is well suited to small-scale applications such as the one we'll...

Summary

In this chapter, we installed Node.js, saw how to interact with it from the command line, and started using it to write web applications. We learned about Express and how we can structure an application using routes and middleware.

Although we've seen some code in this chapter, we haven't really explored the JavaScript syntax in detail. Before adding more functionality to our application, we should make sure that we're up to speed with JavaScript. This is the subject of the next chapter.

Key benefits

  • Learn the concepts of Node.js to gain a high-level understanding of the Node.js execution model
  • Build an interactive web application with MongoDB and Redis and create your own JavaScript modules that work both on the client side and server side
  • Familiarize yourself with the new features of Node.js and JavaScript with this exclusive step-by-step guide

Description

Node.js is an open source, cross-platform runtime environment that allows you to use JavaScript to develop server-side web applications. This short guide will help you develop applications using JavaScript and Node.js, leverage your existing programming skills from .NET or Java, and make the most of these other platforms through understanding the Node.js programming model. You will learn how to build web applications and APIs in Node, discover packages in the Node.js ecosystem, test and deploy your Node.js code, and more. Finally, you will discover how to integrate Node.js and .NET code.

Who is this book for?

This book is for developers who want to learn JavaScript and Node.js. Previous experience with programming is desired, but no JavaScript or Node.js knowledge is required. The book focuses mostly on web development, such as networking, serving dynamic pages, and real-time client-server communication.

What you will learn

  • Understand which problems Node.js best solves
  • Write idiomatic JavaScript and Node.js code
  • Build web applications and command-line tools
  • Minimise complexity and efficiently solve difficult problems
  • Test and deploy Node.js applications
  • Work with persistent data
  • Implement real-time client-server applications
  • Integrate .NET and Node.js code

Looks like it's covering all of the topics I thought it would.The one exception is Visual Studio. I wish it covered Node.js development using Visual Studio more thoroughly.

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.
