The video will cover five topics: types of applications, examples of applications, the concept of Single Page Applications (SPAs), their advantages, and how to create an SPA in React.

What is the primary issue with traditional web applications that SPAs aim to solve?

Traditional web applications require the entire page to be re-rendered with each user interaction, which can slow down performance. SPAs address this by only updating the necessary parts of the page without a full reload.

Can you create a Single Page Application using React?

Yes, you can create a Single Page Application using React. The video will explain how to do this using the React Router, a third-party library.

What are some examples of Single Page Applications mentioned in the video?

Examples of Single Page Applications mentioned include Facebook, Google Maps, Gmail, and Google Drive.

What is a Single Page Application (SPA)?

A Single Page Application (SPA) is a type of web application that dynamically updates the content of a page without requiring a full page reload. This allows for a more seamless user experience.

Why are SPAs typically faster than traditional web applications?

SPAs are typically faster because they only update the necessary parts of the page, reducing the amount of data that needs to be loaded and processed, leading to quicker interactions and responses.

What is the role of React Router in creating an SPA with React?

React Router is a third-party library used in React to handle routing for SPAs. It allows developers to manage navigation and rendering of different components without reloading the entire page.

What advantage does an SPA have regarding server load?

An SPA reduces server load because it makes fewer requests to the server. Instead of reloading entire pages, it only requests the data needed to update the current view.

Keywords

💡Single Page Application (SPA)

A Single Page Application, or SPA, is a web application that interacts with the user by dynamically rewriting the current page rather than loading entire new pages from a server. This concept is central to the video's theme, as it discusses the advantages of SPAs over traditional multi-page applications. The script mentions that SPAs can load templates without refreshing the entire page, which is exemplified by the script's reference to applications like Facebook, Google Maps, Gmail, and Google Drive.

💡Web Application

A web application is a software program that runs on a web server and is accessed through a web browser. In the context of the video, web applications are categorized into two types: single page and multi-page applications. The script uses the term to introduce the concept of SPAs and to contrast them with traditional web applications, which reload the entire page for navigation.

💡Server-Dependent

The term 'server-dependent' refers to applications that rely on the server to process requests and send back responses. In the video script, this concept is used to describe traditional web applications where every user action requires a server request, leading to the full page reload and affecting the application's performance.

💡DOM (Document Object Model)

The Document Object Model, or DOM, is a programming interface for HTML documents. It represents the page so that programs can change the document structure, style, and content. The script refers to the DOM in the context of how SPAs improve performance by not re-rendering the entire DOM when navigating between pages.

💡React

React is a popular JavaScript library used for building user interfaces, particularly single-page applications. The script mentions React in the context of creating SPAs, and it discusses the use of React Router, a third-party library, for navigation in SPAs built with React.

💡React Router

React Router is a standard library for routing in React applications. It is mentioned in the script as a tool that developers can use to create SPAs within the React framework, allowing for page transitions without reloading the web page.

💡Navigation

In the context of web development, navigation refers to the process of moving from one page or section to another within an application. The script discusses the difference in navigation between SPAs and traditional web applications, highlighting how SPAs can navigate without a full page reload.

💡Performance

Performance in web applications refers to how quickly and efficiently they run. The script emphasizes the performance benefits of SPAs, noting that they are faster because they do not require the server to re-render the entire page for every user action.

💡Subscription

A subscription in the context of the script refers to the act of subscribing to the Techinfo Yt YouTube channel. The presenter encourages viewers to subscribe if they have not already done so, as a way to follow along with the series on SPAs.

Transcripts

Hello and welcome to Techinfo Yt YouTube channel, today in this video we will talk

about single page application as you can see on the screen, in this we will

cover some five topics like types of application and then

give its example. We will see what is the application at home, what are its advantages,

can we create a single page application in React or not and if we can,

how to do so, then if you have not subscribed to this channel before then do subscribe to

this channel . Subscribe to If you like the video, like it. If you like using it then

do share it with your friends and if you have any questions or suggestions then

do comment below. Types of Web Application So in this, the first thing that comes to me is right

within the application. So its definition can be seen on the screen. Apps test is totally

dependent on the server. These events and definition are basic definition. The meaning of this is to

explain that whenever we perform any query or different,

our request power which is hit to the server. And what happens because of that,

when our system goes down, the comment object model gets rendered again and again,

what happens because of this, the performance of the application becomes slow, which is simply, if you are

from PSP background, then you have seen. If you

work here without core PHP, then you must have noticed that what we do again and again is that we

send a request to the server, like I submitted the form, now we

will get its response back from the server, for which our whole There is a document, it will be rendered double,

so let me explain to you through an example, I have an application

i.e. a website which is made in Ravana Trip, so this is a website I have,

so see what is there in it, you can see. There is a landing page here and here in

the newspaper i.e. not in the vacation in which we have a

menu here of our service and contact so first of all you use it

notice here but what do we have this There is a button of Note i.e. if

you use ROM or you use Google Chrome or you box on Mohan Jhala, now whatever

browser you are using, then in this you relate from here and this

is what we have in this companion. The title of the web application of our website shows us here,

so if we enter any other page here, then see what happens, I

will click on SMS, then see our hall introduction, our complete stomach, which is there again.

It is related, that is, from its double we have created a DOM. Now see what

I have right now, here you can see this image on the skin, now I have

to change only this much, rest I have to keep the teaser like this, so now its So, if I

click on this and click on the service because here I clicked hair speed,

what happened to you for this, the full price which is

rendered back, this is a small application, so you will

not notice any difference. But we can understand it better when we talk about the application on single

then see you see that as I click on any I, then

here what happens from back that our page relaxes if I just

Specifically, see this here, suppose I have a slider of the website or

you can call it an image, then I have to change this, only this much text, still

what is happening with me, the entire value is being rendered in place, so this is The problem we have

is that of Ram Trick application, so to reduce this, single page application is made,

so let's move towards its definition. Single page application or you

can call it S Pye, so what does it mean as you see on the screen. You can see its

definition Single Page Application A different to the

Page Units Use Simple means that you

can get the template loaded in another test without refreshing the entire page as you use in the mode any

application Facebook Google Maps Gmail Google Drive So did you notice that if we

perform there i.e. on Liquid, ours is only this much that

changes there, so let me give you this example, I have an application, so just

open it and tell you. Here, I have an application, so here you

all do it, so I click on any link here, it

will change just by sniffing, the entire document will not change, ours which we use here,

which page is not related. Look here, I had a card for an online shop,

saying that we will see its complete tutorial in the upcoming videos, it

is still a working progress, so this complete application will be created in a year, don't worry.

In the upcoming videos, that is, readers like us, when the suction is complete, we

will create this application, so here I will tell you how this application works on a single,

so see, I will click here and you will notice this

refresh button here. But as I click, see, no moment happened here,

whereas what we were doing here in the environment, as if anyone clicks, then

our plate is here, if you notice, then you can see the whole page, relax, fear.

Whereas what happens in the application on single pen, we

can jump from one tree to another without refreshing the page. If we play on single,

then what is its benefit. See what happens with the single pen application on our don't.

Which is, the load falls less and in short, if I say, then if you have one should not bay,

then how fast is the alarm, if we create an application on a single, then

its speed increases, how does it provide the same number of parts as we need? Now suppose

I am doing this much on iPhone 11pro, I clicked on it here, only

this much point was rendered till we get what we find, this work of navigation above

is like justice, so this is the advantage of single application which will be discussed in the upcoming videos. We

will create this complete web application Mohan Stock Mein i.e. notes

with the help of legitimate demands Concession on TV We will create this complete commerce application Now

what should we do for single phase application in the next video What will we do and

will give the example of router after that What will we do immediately and you tell in the comment section,

after this I will do a mini project for you or if we start a direct leader

then I will meet him. We will see in the next video and this is about the grinder.

Yes but before that let me tell you. Let me give you

what is the function of Single Per Application in React JS. So see how to create Single Per Application in reject case.

So see and if you want to create Single Per Application then there

is no direct method in it i.e. there is no daughter model in Relax. If you or

someone else is using it regularly then you must have noticed there that go to us,

we get the package pendant of the router, we do not have to install any separate package here

but it is different in the report if we have to create an application on a single. We

have to depend on the price of React Router. There is a third party library which is

used to create writing. If you want in the city, you

can use it. It is very popular, so it does not consume much memory. If you do

this then you will be able to use it and its documentation

is very good, you can easily learn it by watching it, so in the next video we will see

how we can use it about React Router and create a

single page application with its help. can do
