We all need to agree that when it comes to technology, things are unpredictable. Whether you're a startup enabler, entrepreneur or developer you need to keep yourself updated for two reasons:

#1. To sharpen your knowledge.

#2. To cherish your business in this competitive world.

Similarly, new trends keep coming on web application development every year. And this time its turn of single page application for web apps.

Some of us still get confused about what is a single page application, hence I've provided a glimpse on it.

Brief on Single Page Application

To understand SPA lets first go to the past. There was a time where the server would reload the whole page whenever users request some part of the data. It used to result in heavy loading.

Now, with the help of the single page application, this problem was completely solved. SPAs as its name suggests, never reload the whole page, only the requested data gets updated.

To make it more clear, when you go for the one-page website, the server will load the whole page in intail time. Later, the server sends the requested data in the form of JSON (JavaScript Object Notation). Thus, the page never gets wiped away but it will be filled with the new information. The principle to build a web app remains the same but the components change.
Popular Examples SPA,
Many of us use single page web apps in their routine but might not be aware of it. Here are a few biggest platform built with SPA,

● Facebook

● Pinterest

● Linkedin

● Airbnb

● Twitter

● Gmail

One thing you should remember here that all these platforms are built with different single page application framework.

To understand better, here is a pictorial representation of single page application.

How Single Page Web Apps Enhance User Experience?

So whats that key thing which provides a better user engagement to the single page web apps?

Here is the answer. As the whole page gets reload only once, the loading speed automatically increases. And as per the Google Research, it shows a good impact on the business and sales, if the page takes approximately 0.2 seconds to load. It is possible to achieve this loading speed with the help of the single page application.

SPAs give an impeccable experience to the users with easy Navigations, innovative layouts and adaptive to different mobile screen sizes. Let us have a look at some of the major benefits of SPAs and how they help to enhance the user experience.

Pros of Single Page Application

● All the data consist under a single location on the client's side, that's one HTML file. Its makes the debugging or upgrading much easier for the developers.

● Another point to note here is SPAs can effectively cache the local data. Thus when a user is having poor connectivity, the local data gets synchronised with the server. But it is only possible when connection allows.

● Single page application provides a liner experience that gives uninterrupted and easy scrolling.

● The debugging is with easy Chrome for single page web apps as you can examine the page components, the network associated with it and much more.

We can thanks here to the frameworks like Angular.js, Ember.js, React.js, Backbone.js etc. In short, single page web apps provide a space to the user in a simple and workable fashion. All these points ultimately enhance the user experience.

Why launch Single Page Web Apps in 2020?

Many of the eCommerce brands launch their platform with single page application as it comes with lesser interruption. Users can do their shopping seamlessly which ultimately leads to more sales. And it is not only convenient for the user experience but even provides relaxation to the developers in coding and deploying.

And it is the phase where everyone is so busy with their daily routine. Hence they expect to have faster navigation and seamless experience while browsing your platform. With SPAs, load delays are almost eradicated, so you can expect a better user engagement.

For instance, you are going through a web app to buy a smartphone, you almost went through 15 pages while surfing. Every time a new page gets loaded and approximate time a page takes to load is 10 seconds. To calculate the time you just spent in waiting for a page to load. It is where SPAs works like a miracle.

I guess, now the whole picture is clear in your mind. You exactly got the idea of why single page application in the future.

When To Avoid Using Single Page Application?

When your focus is on SEO (Search Engine Optimization), you must avoid using single page application. Its comes with poor SEO optimization. The main reason for it is that the URL does not change as various pages here do not have a unique URL address.

Search bots cannot scan such pages hence it becomes hard to optimize. In comparison to the traditional page, single page application is less secure due to XSS (Cross-Site Scripting).

Another thing is a memory leak of javascript, which may lead a powerful system to slow down.

Thus, have a look at what your business is all about and then decide whether to go for single page application or not.

Summing It Up

I guess, still, a question will be rolling in your mind. When to use single page application?

Straight to the point, if you want an excellent user engagement between your application and them, single page web apps is the best choice. To offer the best real-time experience to the users, web apps like Google-Maps use single page application.

Whenever users tap on the place markers they get the information as they move from one place to another.

In short, it is a good option if you're planning to build a dynamic platform. Again it is one of the types of web apps which is in trend. Choose the one which suits best to your platform.

Currently, there are two ways of building websites: as multi-page applications (MPAs) or as single-page applications (SPAs). SPAs are more modern, but that does not invalidate MPAs. The decision between a single-page and multi-page application depends on business goals and the future architecture.

It’s fairly standard these days for a business to have its own website. It’s a great way to showcase your services, products, and credentials. Many companies in 2021 exist and operate solely online and do not have a “bricks and mortar” presence, such as a shop or office.

It's fairly standard these days for a business to have its own website. It's a great way to showcase your services, products, and credentials. Many companies in 2021 exist and operate solely online and do not have a "bricks and mortar" presence, such as a shop or office.

In order to get found by potential customers, marketing professionals spend millions each year on advertising through social media platforms and search engines. Search Engine Optimization (SEO) remains the foundation for many business endeavors, providing 'free' traffic from a search engine such as Google and Bing.

User Experience (UX) is also crucial. It is no use spending months perfecting your latest SEO campaign and social media adverts if the majority of your website's visitors bounce straight back to the search engine because the site is too slow or too hard to use.

With a SPA, users enjoy the fastest and most fluid experience possible. This is why applications such as Gmail, Trello, and websites such as Angular University, Moneypenny.com, and Airbnb ause SPAs.

What is a Single Page Application?

One of the latest developments in web design, is the use of single page applicatins or "SPAs".

SPAs are a lot faster in terms of the speed that they load and in their general functionality. With a standard website, such as a hardcoded HTML site, WordPress, Wix or Shopify site, the website has to download ingormation from the browser each time a user clicks on a navigation item, in the menu.

With a SPA, as soon as the first page of the website, such as the homepage, is loaded, the SPA no longer has to communicate with the server. It uses a small javascript program that downloads to the users browser in a couple of seconds, to load and resolve every required element of the website. It functions much like a desktop application.

Unlike multipage, standard websites, a SPA doesn't reload any identical elements of a page. It downloads an "application shell" on the first page that is visited. So for example, if a website uses the same header and footer throughout, this is loaded once and does not have to reload when the user navigates to a new page. With a standard website, the whole page has to load and resolve each time a new page is navigated to by the user.

Pros & Cons of Single Page Applications

The whole application is loaded only once. If a users internet went down mid-session, the SPA would still work.

Some of the drawbacks, or cons of SPAs include:

A small percentage of internet users like to disable Javascript. This can help provide a faster web experience, but will stop many websites from functioning fully. The big difference between SPA and standard websites, is that SPAs use Javascript to load the HTML and other content. So almost nothing will work on a SPA website if the user has JavaScript disabled.

A big issue with SPAs is the difficulty when it comes to SEO. Due to the amount of code and Javascript, Google can struggle to crawl the website properly. SEO professionals can also struggle to optimize SPA websites, if they are not competent at coding.

SEO & Single Page Applications

If you or your company is going to use a SPA, then it is really important to start with SEO in mind. It is not unusual for a SPA to go live and replace a standard multipage website, only for rankings to plummet, in turn losing substantial amounts of revenue for the business.

Common issues with SPA websites include unsupported features such as APIs, issues with URLs resolving and displaying. There can also be issues with tracking - making it difficult to identify if tracking came from a Google Ads, a Google organic listing or a social media source.

Finally, SPAs can have issues displaying error pages and the correct http status codes. For example, if a page does not exist or has been moved, it is common for a SPA website to show a 200 status code - which suggests everything is fine, instead of a 404 status code, which tells the server and the user that the page cannot be found.

Resolving SEO Issues with SPAs

As ever, its always better to bring forward solutions, instead of problems.

For example, if the URL does not change when a user clicks onto a new page (or "view" as they are sometimes called in applications such as SPAs), this is a problem, as Googlebot and other search engines will only index a single page.

To overcome the URL issue, use the history API and proper link HTML markup. You can learn more about the history API in this YouTube tutorial and link markup in this tutorial.

To ensure that the SPA displays the correct https status codes, configure the server to respond with a specific status code for a given URL. For example, if all pages that don't exist are redirected to a specific URL such as example.com/notfound/ then the server can be configured to generate a 404 https status code every time example.com/notfound/ is loaded. You can learn more about how to set this up, in this YouTube tutorial from Google Search Central. This will tell both the user and Googlebot that there is an error and that the page shouldn't be indexed.

Campaign Tracking & Single Page Applications

The issue with tracking URLs with SPAs, is that the URLs don't load or reload in the same way that they do on a standard HTML website.

As mentioned above, it is important to incorporate the history API into the development of a SPA to ensure that the user sees the different URLs in the address bar.

Google Tag Manager has a special trigger that can read the information that gets sent to the history API.

To make use of Google Tag Manager, you will need a google account and you will need to sign up for a specific Google Tag Manager account.

You then need to install the necessary code on your website to use and implement tags. You can do this yourself, or if it is too technical, you can always hire a freelancer on a website such as UpWork or PeoplePerHour.

To install the tag, go to Google Tag Manger, click on "Triggers" in the side menu. For "trigger type" click on "history change", then click "save".

Next click "variables" and click to check/tick all of the "History" variables, including "New history fragment" and "history source". Refresh everything and then navigate back to your website.

Single Page Applications can provide a higher standard of user experience, which in turn can give your company a competitive advantage. However, even with experienced developers and a highly skilled team of SEO executives, the deployment of a SPA, rarely seems to go smoothly. It can certainly help to be aware of all the common problems related to SPAs and SEO, so that you can prevent many of them from occurring in the first place.

Google Tag Manager is a great tool in general and can help with tracking campaigns, especially with SPAs. Click here to see a full tutorial of Google Tag Manger for beginners. One final thing to be aware of with SPAs are potential security issues. Because of cross site scripting, hackers can potentially gain access to the client-side of a website and insert new scripts.

SPAs are a great idea when you have a dynamic website with a small data volume and if you are thinking of developing a mobile app - as the backend API can be used to develop desktop and mobile apps.

Single-page applications are the most popular way to create websites that load faster without hitting the server every time the user interacts with the application.

In this guide, you'll learn about single-page applications, why we need to use them, and how they compare with multi-page applications.

The major difference between multi-page and single-page applications is that single-page apps download the page a single time once it is executed.

As soon as a user interacts with the app, only the required component will be modified, not the complete application, which makes a single-page app much faster in terms of interactivity. Single-page applications offer a much better user experience (UX), meaningthat users can navigate easily between the different pages of an app without waiting for the pages to load.

An important feature of single-page applications is performance. They get a performance boost by loading HTML, CSS, and JavaScript resources as soon as the website is loaded.

The reason is that when users come to an application, they need the shortest possible wait time so that they can do their work and leave. The performance reflects the demand for the application.

If the application does not provide the necessary performance, users may leave that app and choose another platform. That's one of the primary reasons developers choose single-page apps nowadays.

There are other advantages as well:

There are also some disadvantages to using single-page apps:

Multi-page applications contain tons of pages, and when users request resources or interact, the app has to go to the server, download the resource, and show it to the user.

The process is quite slow and painful when it comes to performance, but mostlarge companies use multi-page applications because they have to deal with tons of services and products.

Onedisadvantage is in flexibility and optimization. Users may need to put in more effort, and required changes may be costly over time.

Other disadvantages of multi-page applications include:

Understanding the difference between single-page apps and multi-page apps can help you decide which type of application structure you need. Here are some things to keep in mind:

To build powerful single-page apps, you need a powerful framework or library. There are plenty of options to choose from, including:

These are some frameworks and libraries that can be used to create single-page applications without any fuss.

This guide introduced you to single-page applications and multi-page applications, including their use in real-life scenarios.

There are certain advantages and disadvantages of single-page and multi-page applications, and knowing them can help you choose the right type of application for your project.

# data[].attributes.attachment_link.readable_text
In this tutorial, before going forward with what is Angular and what is the difference between its major versions, let's first discuss what is Single Page Application (SPA) in Angular or React.

What are Angular or React?

So, before starting the learn Angular or React, it is very important that we know their definitions and also what is the exact meaning of that definition.

So basically, they are JavaScript Framework(hacker.io) that allows us to create reactive Single-Page-Application( SPAs).

What is the meaning of Single Page Application?

SPA is an application in which we think, or we seem that we visit the different pages but at last or in the end, our page never changes.

In layman terms, we can say that SPAs are the application that works inside a browser and during the usage of the application, they don't require the page reloading.

So, it's like only one HTML file and a bunch of JavaScript code we got from the Server and everything you see on your application screen and every change in your application rendered in the browser.

So why this is an awesome approach? This approach is awesome because it gives the user a very reactive user experience.

Also, JavaScript is much faster than having to reach out to a server for every page change and for every new piece of data you want to display on the screen. So, this approach allows you to create a web application that is much faster and looks like a mobile application.

When we click any button or element in Angular SPAs then only that single page changes that are one HTML page.

So, in simple terms, we can say that there is one single HTML page that is changing continuously.

How it is possible?

All this happened due to JavaScript. So, JavaScript changes the DOM, changes whatever is displayed in the browser by changing the HTML code during runtime.

So, this is the reason that we never see that our page is reloaded or refresh completely because we only change the currently loaded page.

Also, if you inspect the source code of a Single Page Application page then you can see that inspect does not contain content you write for your page.

So, we have only one single HTML element in SPAs which seems to be a built-in one but that's Angular and we can say that here Angular does its job.

Advantage of Single Page Application

There are many advantages of SPAs and we are discussing a few of them here:

1. Single Page Application is very fast and the reason behind it is that most of the resources that are HTML, CSS and Scripts are only loaded once throughout the total lifespan or total life of an application. So, it is only data that is transmitted from one place to another.

2. In the case of Single Page Application, there is no need to write code for rendering the pages on the server. We can easily start and kick-off development from a file: URI.

3. Also, you can easily develop the mobile application because developers or programmers can reuse the same backend code for web development and for native mobile applications.

4. When it comes to caching then Single Page Application cache local storage effectively. SPAs application sends only the request one time and stores all the data and due to this, it can work offline as well.

5. Also debugging is also easy with SPAs and Chrome.

Disadvantage of Single Page Application

1. The main disadvantage of SPAs is that they require JavaScript to be present and enabled in the browser. So, if any user disabled the JavaScript from the browser then SPAs do not work in a proper way.

2. Sometimes most of the power systems also got slow due to the memory leakage in JavaScript. Also, JavaScript memory leakage can cause other problems as well.

3. When it comes to the download then it is very slow to download because very heavy frameworks are required to load to the client.

4. Also, SEO optimization is very difficult in the Single Page Application. When it comes to loading the content then it uses the AJAX which is like a method of exchanging data and updating our application without refreshing the complete page.

Conclusion

Let's concluded the overall discussion of Single Page Application in 2-3 lines, and below are these lines.

So, in layman term, we can say that Single Page Applications are the application that works inside a browser and during the usage of the application they don't require the page reloading.

Single Page Application is all about giving a very fast and reactive experience to the user.

This is all about the basic information of the Single Page Application.
