This course deals with all things server-side. We base the entire course around the NodeJS platform. We start with a brief overview of the Web protocols: HTTP and HTTPS. We examine NodeJS and NodeJS modules: Express for building web servers. On the database side, we review basic CRUD operations, NoSQL databases, in particular MongoDB and Mongoose for accessing MongoDB from NodeJS. We examine the REST concepts and building a RESTful API. We touch upon authentication and security. Finally we review backend as a service (BaaS) approaches, including mobile BaaS, both open-source and commercial BaaS services. At the end of this course, you will be able to: - Demonstrate an understanding of server-side concepts, CRUD and REST - Build and configure a backend server using NodeJS framework - Build a RESTful API for the front-end to access backend services

Before you embark on this course, let me take you through a quick tour of all
the learning resources that are available in this course.
And how best you can make use of these learning resources to
maximize the benefit of doing this course.
The course itself is organized into four modules.
Each module has an overarching theme that guides the design of the module.
A module itself is divided into multiple lessons,
each lesson concentrating on one specific topic.
There will be an assignment due at the end of each module.
Each module typically corresponds to one calendar week of work,
so this whole course could be completed in four weeks' time.
But please take the time necessary for
you to completely understand before you move on to that next module.
As already mentioned, each module is divided into multiple lessons.
Each lesson itself is organized in this manner.
A lesson starts out with a set of objectives and
outcomes being specified for that lesson.
Then following that,
you will have a set of videos that introduce you to the concepts and
technologies on which this particular lesson is concentrating on.
This will be followed by one or more hands-on exercises
that will help you to understand their concepts and
technologies by doing the exercises.
At the end of each lesson you will also have additional resources,
which will point you to resources that might be useful for
the topic covered in this particular lesson.
Let's take a quick tour of your course page.
So as you go to the course homepage,
you will find a lot of details about the course there.
You'll also notice that the course itself is organized into weeks,
each week corresponding to one module.
Let's visit one particular module to learn how the module itself is structured.
So as you go to each module, you will see that the module will have
a brief introduction on the theme of that particular module.
Then there'll be a set of learning objectives for that particular module.
Following that, you will have a set of lessons.
As I mentioned earlier, each lesson will be organized into a set of items.
Let's take a quick tour of this lesson on Introduction to Node.js and NPM.
As you click and go into that lesson,
you will notice that at the start of the lesson you will have the objectives and
outcomes for that lesson explicitly specified.
I would urge you to take a few moments to read through this document
because this will clearly set up the goals of this lesson and also tell
you exactly what you will achieve at the end of that particular lesson.
Following that, you will have a set of videos
that will explain some of the concepts and
technologies relevant to that particular lesson.
I would urge you to watch these videos first.
Following this set of videos, you will have a one or
more hands-on exercises for that particular lesson.
The exercises themselves will be illustrated through a video which
gives you step-by-step progress of that particular exercise.
So I would strongly urge you to watch this video in order to
understand how to do the exercise.
Also, in the exercise, I will explain a lot of details
about why each step is being performed in that particular exercise.
Now in addition to the video illustration of the exercise,
you will also have a summary of the instructions for
that particular exercise given as a separate document following that video.
The objectives and outcomes for that particular exercise will be listed out.
Then each step will be illustrated briefly in this particular document here.
So once you watch the video, you can also use these exercise
instructions as a guide as you perform your own exercise routine.
In addition, the exercise instructions will also contain
code snippets that will be useful for you to do your exercise.
I would strongly urge you not to simply cut and paste these code snippets, but
instead understand exactly what you're doing in each step.
And then either type in the code yourself or copy and
paste the code from the instructions here.
Furthermore, for every video,
if there is a set of presentation slides, those would be available
in the downloads to the right of this video there on the webpage.
Also, if you go to their additional resources that are provided for
you at the end of each lesson,
you will also have links to the PDFs of the presentation.
So there are two places from where you can download the PDFs of
the presentations about the concepts and technologies for each module.
You'll also have links to Node.js documentation about the specific
concepts and technologies covered in that particular lesson.
I will also give you links to articles, blogs, or
additional resources from the Internet that might be useful or
relevant to this particular topic of that lesson.
I would suggest to you to spend some time looking up these additional resources so
that they may aid you in also furthering your understanding
of the specific topics covered in that particular lesson.
To summarize, the learning resources in each lesson is organized into the set
of video lectures, illustrating the concepts and technologies.
Then hands-on exercises which include both step by step instructions
in the form of a video, and also written instructions for the exercises.
And additional resources that might be useful for
you relevant to that particular lesson.
Also, as I mentioned, at the end of each module you will have an assignment due.
The tasks to be performed in the assignment will be illustrated
through a video where all the tasks that
you need to do in the assignment will be shown to you.
Thereafter, you will have a written document that explains
the details of that assignment.
This written document will give you access to that resources that might be required
for this assignment.
Following that, you will have the set of objectives and outcomes for
the particular assignment given to you.
Then the requirements of the assignment will be specified in terms of
that set of tasks that you need to complete and the steps for
each task will be illustrated there.
At the end of the document, you will also be given the review criteria,
the criteria based on which your submission will be judged for
this particular assignment.
As you embark on this course, let me quickly remind you of
a Sanskrit subhashita, or a wise saying about learning.
It goes as follows.
[FOREIGN] What this means is that one-fourth
of your learning comes from your teacher,
one-fourth of your learning comes
through your own intelligence.
As you do the steps, use your own intellect to analyze and
understand what you're doing.
One-fourth of your learning comes from your classmates.
So this is where interacting with your colleagues that are also taking
this course at the same time, through the discussion forums,
would also help you to understand the concepts.
And finally the last fourth comes only through experience or only with time.
As you learn and make use of the concepts and technologies that we learn
on this course, you'll begin to understand more and more about this particular topic.
Let me leave you with my best wishes for you so
that you will get the most out of your journey through this course.
Wish you all the best.
