CHAPTER 1
INTRODUCTION
1.1 OBJECTIVE OF THE PROJECT
The main objective is to build a web application for Books which can help reader and even
authors. The Book Loft is a MEN(MongoDB, ExpressJs and NodeJs) Based web application
where user can read and write review, check prices of different E-Commerce platforms, authors
can publish books which will help them to advertise there book, live prices over a graph for last
6 months (Graphically) so the buyer will get to know the lowest price of that book.
1.2 TECHNOLOGIES
 MongoDB  NodeJs
 ExpressJs  Keepa
 ElfsightAPI  Earnkaro
MongoDB :- MongoDB is a document database with the scalability and flexibility that you want
with the querying and indexing that you need. The document data model is a powerful way to
store and retrieve data in MongoDB that allows developers to move fast. MongoDB's horizontal,
scale-out architecture can support huge volumes of both data and traffic.
NodeJs :- Node.js is an open-source, cross-platform, back-end, JavaScript runtime
environment that executes JavaScript code outside a web browser. Node.js lets developers use
JavaScript to write command line tools and for server-side scripting—running scripts server-side
to produce dynamic web page content before the page is sent to the user's web browser.
Consequently, Node.js represents a "JavaScript everywhere" paradigm,[6] unifying web-
application development around a single programming language, rather than different languages
for server- and client-side scripts.
ExpressJs :- Express is a minimal and flexible Node.js web application framework that provides
a robust set of features for web and mobile applications.
1.3 FEATURES
Compare the prices from various E-Commerce Websites
• Availablility of competitive price history
• Search option to choose books/novels per own interest
• Availabliltiy of filter option according per own interest on basis of: Type, language, price
• User Friendly UI / Responsive Design
• Option to upload books/ Launch book

THE BOOK LOFT
1.3 ADVATAGES OF MEN STACK
Easy to switch between client and server - Having a common language allows you to switch
seamlessly between client side and server side. You no more require a 3rd party server like
Apache. Instead, Node.js allows the developer to open the application on the server.
Highly flexible - Allows you to do more stuff that just act as a platform for developing web
applications. For instance, with MEN you can host the application on a cloud in case you want to
test the web application after development. Additionally, MongoDB, the database system used in
MEAN, is a system built for the cloud. Once, on the cloud, it provides automatic sharing and
cluster support across servers.
The quickest way to come up with an MVP - MVP is a minimum viable product. In most cases,
it comprises of the product (in this case a web application) with its preliminary set of features.
These are the most necessary features that customers are looking for.
A MEN Stack development company will ensure you achieve the MVP in the shortest possible
time. This is down to the fast nature of the framework.
An ever-increasing online community - Mean is a highly reputed framework that’s proven to
work well for lots of developers around the world.
Lots of enthusiastic developers who work with MEAN have given rise to a strong and helpful
online community. You only need to Google an issue to understand how comprehensive the
solutions are and how intricately connected harboring it is.
This is only because MEAN Stack is a proven tool for developers and you must opt for it without
harboring any inhibitions. In fact, right from small start-ups right up to tech giants, everyone is
making use of Node.js.

DESIGN METHOD
3.1 SCENARIOS
Authentication - Authentication is the process of recognizing a user’s identity. It is the
mechanism of associating an incoming request with a set of identifying credentials. The
credentials provided are compared to those on a file in a database of the authorized user’s
information on a local operating system or within an authentication server.
function checkCommentOwnership(req,res,next){
if(req.isAuthenticated()){
Comment.findById(req.params.comment_id, function(err, foundComment){
if(err){
console.redirect("back");
}
else{
if(foundComment.author.id.equals(req.user._id))
next();
else{
req.flash("error","You don't have permission to do that");
res.redirect("back");
} }
});
}
else{
}};

THE BOOK LOFT
Authorization - Authorization is the function of specifying access rights/privileges to resources,
which is related to information security and computer security in general and to access control in
particular. More formally, "to authorize" is to define an access policy.
function isLoggedIn(req,res,next){
return next();
}
res.redirect("/login");
};
isAdmin - It is a boolean function that will return true if the URL being accessed is in the admin
section, or false for a front-end page. ... This function does not verify whether the current user
has permission to view the Dashboard or the administration panel.
function checkAdmin(req,res,next){
if(res.locals.currentUser.role===1){
next();
}
else{
req.flash("error","You need to be logged in to do that");
res.redirect("/");
}
}
else{
} };

COMMENT
RESULT
So finally we came across making the final web app for The Book Loft. The app has been made
by using technologies: Nodejs, Javascript, MongoDB, ExpressJs, EJS, HTML, CSS and many
more. The application has been connected with the MongoDB Server.

CHAPTER 5
CONCLUSION
In this project, I have developed a Full Stack MEN based web application on books by providing
full details on it. This project also emphasizes on main ideas related to the topic.
I took the ideas and researched about this topic from the websites and some books which are
mentioned in the references. I wish this project will be a useful and the knowledgeable one.
FUTURE WORK
 Adding more features
Providing vouchers for launching book
Earrings for Authors (If traffic is buying books from our affiliate links)
