VS.
.NET Core vs.
Node.js:
What to
Choose
When?
www.bacancytechnology.com

The Big doubt of choosing the ideal
framework for entrepreneurs like you
always prevails. There are several options to
choose from, but the top of the list is still
the trickiest problem. As I was skimming
through Quora, I realized that both
enthusiastic web application developers
and entrepreneurs are frowning over
choosing between the newest sensation
Node.js and the classic ASP .NET Core
framework for their upcoming app
development.
After spending over an hour of question-
answer reading, I finalized that I’ll come up
with a coherent blog post that will serve as
the “Must-read Manual” before completing
the tech-stack for your future application.
So here I am with this post on Top 03
Considerations When electing between
Node js Vs. .NET Core. For beginners and
startup boosters, I will start from scratch.

What is
Node js?

Node is a javascript runtime environment
that is open-source, which developers use
for server-side scripting. It has the potential
of building a web application both client-
side and server-side with this one
programming language. The first release of
Node.js was out in May 2009.
Node.js supports the functioning of various
operating systems, including Windows,
Mac, Linux, FreeBSD, OpenBSD, Smart OS,
and to z/OS and IBM AIX.

What is
.NET Core?

The famous successor of the ASP .NET
framework is .NET Core, a software
framework for Windows, macOS, and Linux.
It is open-source and free. It supports C#,
F#, and VB for web app development and
building libraries.
Read a brief on .Net Core.
Both these frameworks are open-source and
have their strengths and limitations.
However, to help you ease out your
dilemma, I’ve compiled three points of
considerations before you make a decision.

Considerati
ons before
choosing
your
Framework

Node.js uses the single-threaded callback
handler, whereas .NET now uses
asynchronous programming for request
handling. Earlier, the old ASP .NET version
used a synchronous pattern, though.
When using Apache, it uses a separate
thread to handle each of your requests.
However, Node.js being single-threaded
uses a single thread and answers your calls
asynchronously, without blocking your
requests. Thus, Node.js is an ideal choice for
I/O bound apps.
You can cluster the single-threaded request
handling using Nginx- load balancing,
native Node js clustering, or Node.js process
management PM2 using which you can
utilize maximum server cores to startup as
much your CPU can handle.
1 a. Request Handling in
Node.js

The downfall of the ‘single-threaded’
characteristic of Node.js also brings a
“callback-hell,” which may introduce
complexities in your code.
See how Node.js handles a database query
asynchronously:

Before the .NET version 4.5, it handles
requests via the traditional Apache/PHP way,
i.e., synchronously. So, each I/O process
would require individual threads, and all the
threads execute synchronously. This method
has barriers and doesn’t stand against the
Node.js request handling mechanism.
However, the async/ await pattern of request
handling introduces since v4.5 manages
requests without blocking your app
execution. It is a task-based model that uses
callback, and async/ await programming
models or promise.
Let us see an alternative approach to Node.js
as above, where ASP .NET core code using
async method handles incoming requests
without using boilerplate startup code:

Core

[Source: Medium]
As you saw, comparing Node.js Vs. .NET Core
for the matter of request handling, ASP.NET
Core will handle more requests because it
handles parallelly. However, in the case of
context switching, when you use many
thread-shared variables, Node.js is better
because .NET can be costly.

You must consider both .NET Core and
Node.js framework because both offer
diverse capabilities if you are thinking of
working on containers or containerizing
your roadmaps.
While using Node.js containers, a Node.js
developer can build their app faster and
quickly reproduce build components.
Node.js implements the microservices
architecture, which enables it to deploy
horizontal scaling for rapid development. In
this way, developers can use containerized
Node.js applications to ramp up or shrink
down as per workload requirements.
2. Container Capabilities

Similarly, in .NET Core, developers can
deploy and build desktop, mobile server, or
web-based workloads. ASP.NET Core uses
Microsoft Nano Server container handling
which, you can yield a custom runtime
environment in Windows or Linux
distributions.
Nano Server is a remote administered
server OS for private clouds or data centers.
It is a small Windows server supporting 64-
bit tools/ agents/ apps.

Microsoft created ASP .NET in 2002, which
is an open-source server-side framework.
Developers can use .NET Core to build apps
and dynamic web pages using the
traditional C#, Visual Basic, and F#
languages. This reason makes the .NET
community strong, especially on
Stackoverflow.
Ryan Dahl, an Engineer, created Node.j in
2009 after 7 years of .NET Core’s release.
Using Node.js, developers can write back-
end code with the help of front-end
languages. With its ease and popularity,
Node.js has gained excellent community
support in a short time. It has a unique
GitHub fan club.

3. Community Support

The Mystery
Busted
You finally get the answer straightforward
in this section. Here’s when to choose for
.Net Core and when for Node.js. Get it.

.NET Core-
Highly
Suitable for
Enterprise
Applications

.NET Core has a favorable history and has
earned trust amongst business
corporations. It has been a reliable platform
for many entrepreneurs over the years,
owing to its immensely useful tools and
library support.
Another reason is that javascript doesn’t
support static types, which are essential for
writing a million lines of code, and thus
.NET Core has a larger share over the
entrepreneurial market.

Node js
Preferable for
Large Web
Applications

Node.js is the right choice for building a fast
and scalable hi-tech application, which is
data-intensive and requires technical
support like IoT, AI, and more. Node.js has a
non-blocking architecture that enables it to
create flawless media applications with its
full-stack technology orientation.
