Basics of Framework
programming
Introductory session

Programming
Language
 In 1990’s, all of us developers, would develop solutions in one
language or the other
 For those who were comfortable with English, programming
language was simple to learn
 Just as each language we speak has a grammar, the programming
languages too had syntax which were different for each

Protocols
 Then came a situation where in data is not used only in one
computer, but across computers.
 That is similar to talking to a stranger
 Just as each culture has a way of handling strangers
 In the same way, in software development field too, we needed to
establish protocols and follow them

World of
internet
 Internet was a big revolution and it change the entire world
 Before internet, developers would design their own screens and
capture and display data
 With Internet, the dynamics changed
 Everyone had to use the same UI tool – the browser
 www organization developed the rules – i.e. the protocols
 HTTP - HypertextTransfer Protocol (HTTP) is an application-layer
protocol for transmitting hypermedia documents, such as HTML.
It was designed for communication between web browsers and
web servers, but it can also be used for other purposes (Referenced from -
HTTP - MDNWeb Docs – Mozilla https://developer.mozilla.org › en-US ›Web › HTTP)

TP/Overview
 HTTP is a client-server protocol: requests are sent by one
entity, the user-agent (or a proxy on behalf of it). Most of the
time the user-agent is a Web browser, but it can be anything,
for example, a robot that crawls the Web to populate and
maintain a search engine index.
 Each individual request is sent to a server, which handles it
and provides an answer called the response. Between the
client and the server there are numerous entities, collectively
called proxies, which perform different operations and act as
gateways or caches, for example.

HTTP/Overvie
w
 In reality, there are more computers between a browser and
the server handling the request: there are routers, modems,
and more. Thanks to the layered design of the Web, these
are hidden in the network and transport layers. HTTP is on
top, at the application layer. Although important for diagnosing
network problems, the underlying layers are mostly irrelevant
to the description of HTTP.

Domain world
 At one end of software development isTechnology
 Another important aspect is the Domain

Domain
emergence
 Since computerization was a new field, many domains need a
software tool
 This was during the 1990s –The programming age
 Many conflicts would arise due to the fact that the programmer
does not know the intricacies of the Domain
 Also, many domains needed the same modules – like
Authentication,Authorization, Profile administration etc.

Frameworks
 To reduce the conflicts and optimize software development, a new
layer was added on the application layer.
 That is the “Frameworks”

What is
Framework?
 In computer programming a framework can be best defined
as a tool which allows to develop software and create
systems.
 This tool itself is a set of processes which is why a framework
is defined as abstraction by engineers.
 And abstraction is similar to the generalization, meaning that
it simplifies the arrangement of details, leaving only the most
necessary structural things to allow the system work.

What are
Frameworks
Used For and
How They
Operate?
 Frameworks are designed to save time and provide shortcuts.
 It is also true that frameworks are in many ways similar to
libraries, so some even confuse these two.

 Statistically, time spent to learn how to operate a framework
pays off in the end, since it allows doing more in less time but
with a lot more quality.
 That’s because even an inexperienced programmer operating
within a framework can easily integrate great code into his
program and generally this is what programmers do because
for a myriad of processes there already exists code that is
perfect.
 All that’s left is to integrate it. Suppose your project needs
Process A + Process B + Process C. A developer looks for
the best code for each of the processes and unites them,
operating within a framework.

Popular ones
 Among the most widely used frameworks that we employ in
development are React, NodeJS, Angular but there are
many other as well.
 Frameworks like Django or Xamarin are used for more
nuanced aspects of development on certain projects that
require special approach.
 For a variety of commercial purposes Angular, React and
NodeJS best fit the requirements and they do streamline a lot
of development mechanisms to allow continuous delivery and
rapid deployment of the completed code.
