View Curriculum
  • This example-packed video course starts with taking viewers through the fundamentals of Node.js. The steep but gradual learning curve will then take them some advanced topics such as streams, transformers, and micro services. The course will conclude with teaching viewers how to scale up their application and test their code.

Node.js is a modern web framework that allows you to build rich applications. As a developer, you need to know just one programming language to build an application that can be executed anywhere, be it the server, console, browser, or on your mobile phone.

This course begins with explaining how Node.js works and what its architecture is all about. You will then learn to create your first Node.js application and also create a command line tool for Node.js. Next, you will learn how to work with commander.js and use the event emitter because events are a powerful extension that can be used in our application.

The course will then teach you to use and define streams and transformers, after which you will be skilled to build a web server with Express.js. This will be followed by taking you through how to read, write, and manipulate files in the file system with Node.js. You will even learn how to create micro services with the loopback API framework and Seneca.js, post which we will scale our node.js application and test our code. Finally, you will complete your learning journey by using these APIs to create a web server, access file system, and create real-time interactions.

With this course, you will be able to build your own tools, along with big network and real-time applications.

Understand that when you want to build a tool in the console, you can use node.js to build it for you.

Preview 06:21

Creating CLI tools with just the basic Node.js API is hard. So to cover this, we have some useful libraries at our disposal.

Commander.js and prompt

We want to have access to our tool with a common name. Now when we want to use our tool we need to go to the location of the script and perform node <scriptname>.

Make Your Tool Global
Asynchronous Event Driven Programming
4 Lectures 28:25

Understand what are the events in node.js and how can we use them in our advance.

Preview 05:36

Timers are also a sort of event, an event scheduled in time. How does this come along in our entire story?


How can I use the functionality of EventEmitter to my own objects?

Creating an Event

We can go more into depth with events regarding what can we do when we want to listen to an event just once. How can we deal with listeners?

Events in Depth
Streaming Data across Nodes and Clients

Streams are very useful to work with data and to manipulate data. But how are we going to do that?

Preview 06:00

Learn more about how to play with streams and their transformers.

Object Streams

Understand how we can create a simple http-server that listens to http requests.

Creating an http-server

Understand how we can handle data when we post data to our web server.

Handling Post Data
Http and Web Server

If you want to build a big web application, using only the node.js APIsis a lot of effort. So in this chapter, we will dive into the libraries that are created on top of the http libraries of Node.js.

Preview 09:00

Middleware is a very important part of Express. It results in extending the request object and adding a certain value to every request.

Request Middleware

In this video, we explain more advanced middleware and in more detail, the authentication middleware.

Social Logins

To get away from callbacks and to provide a more elegant API to build web applications you can use Koa.js.

Using Node.js to Access File System

When we want to search for a file, we need to iterate over files and folders.

Preview 07:16

How can we react upon a file change by reading and watching a file?

Reading a File

Before we can write content to a file, we need to check whether the file exists!

When you need to upload files to your server, how do you handle this in node.js and Express.js?

Handling File Uploads
Utilizing Multiple Processes
