SPAs differ from traditional websites in that they greatly reduce the number of page refreshes needed to serve up the desired user interactions. They achieve this by leveraging AJAX - a tool that allows the site to exchange information with back-end servers and load data into the application without executing a full page refresh.
More directly, a single page application transfers most of the processing work to the client side, which allows the user to load a single HTML page and dynamically update the content on that page, without refreshing it, as they interact with the application.

The development, deployment, and debugging processes also make SPAs easier for developers. These applications rarely require any server-side coding and can be deployed to a server much like a typical web page. Programmers can also debug single page applications using the Chrome browser, which gives users the capability to monitor network operations, examine individual page elements and review the data connected to each element.
A major advantage of multi-page applications is that each page can be tailored for search engine optimization with specific keywords and content. Also, each page can contain Google Analytics tags, which can help site owners determine which content is reaching clients, which content is receiving the most interaction, and where visitors are finding out about specific types of content.
The additional levels involved in multi-page applications require a much more complex development process. The front-end and back-end systems may be developed independently but must work together to ensure that the user has a smooth experience. This split between the front and back ends also makes the debugging and maintenance processes much more difficult, which can lead to longer downtimes and loss of revenue.
In this particular instance, you might want to opt for a multi-page site that will handle the complex information architecture while providing an intuitive set of buttons or menus that users can leverage to find exactly what they are looking for.
On the other hand, maybe the data queries that are generated by user interactions are not numerous enough to warrant an MPA, so a single page application would be a faster, simpler, and possibly cheaper solution.
The primary takeaway from this comparison is that deciding whether or not a single page application is the right format for your product should begin by taking stock of the objectives that you have for the product and the specific needs of your users.
Both models come with inherent advantages and disadvantages, but when deployed in the right situation, single page applications can provide an outstanding experience for the end user while saving you time and money.
This is supported by data sources like the one below, which shows that interest in developers who are proficient in AngularJS - a programming language that is an integral part of developing single page applications - has skyrocketed.
These hybrid applications function much like an SPA that employs URL anchors as synthetic pages to mimicking the site navigation functionality traditionally found with multi-page applications only. Alternatively, developers might deploy multiple SPAs which share data between themselves. This is achieved by combining single page applications with a server-rendered shell application.
But to successfully operate a hybrid application, you need to optimize it and pinpoint any user experience areas where your user could benefit from having an SPA delivery, and where they would benefit from multi-page delivery.
Search engines such as Google and Bing work by reading HTML data of websites when you enter a search. With standard HTML websites storing pages in a hierarchical format with data on each, a search engine has a lot to work with in terms of searching and finding.
The slug URL contains relevant words, all of which should relate back to the data the page is trying to convey. These are much more human-friendly and clean, they should not contain any hashtags but if your links do you can get around this by using your router.
dotCMS makes use of Google Analytics to allow you to track and report usage of your SPAs. The codes given through Google are simply attached to the content within your website via the dotCMS GUI, which once again helps to streamline single page application development.
dotCMS is designed to deliver content-driven applications at scale. Whether you're building a network of global websites, an employee intranet, customer portal, or single page web application, dotCMS helps you manage content, images, and assets in one centralized location and deliver them to any channel.
This free book is what I wanted when I started working with single page apps. It's not an API reference on a particular framework, rather, the focus is on discussing patterns, implementation choices and decent practices.
Enter the modern single page web application (SPA). With the near universal availability of capable browsers and powerful hardware, you can push most of the web application to the browser; including HTML rendering, data, and business logic. The only time a client needs to communicate with the server is to authenticate or synchronize data. This means users get a fluid, comfortable experience whether they're surfing at their desk or using a phone app on a sketch 3G connection.
If your website is a jumpy collection of linked pages, you are behind. Single page web applications are your next step: pushing UI rendering and business logic to the browser and communicating with the server only to synchronize data, they provide a smooth user experience, much like a native application. But, SPAs can be hard to develop, manage, and test.
Note: Other software packages for completing these applications maybe available from other sources; however, it is essential that the type size and format specificationsare met. Otherwise application processing may be delayed, or the application may be returned tothe applicant without review.
As every designer knows, file functionality depends on file format. Web pages are built using a file format called HTML. Because of this, HTML is one of the most widely used formats all across the world. Unlike PDF, HTML does not require a separate software platform to view or access the files. It can run in any internet browser, making your files easily accessible. Also, HTML files are typically smaller than PDF files. Converting files to HTML makes it simple to add content from a PDF directly to a web page. To transform your PDFs into web pages, all you need to do is resave them as HTML files. Follow this step-by-step guide to learn how.
One way to embed a PDF in a web page is to use the HTML tag. This tag allows you to define the parameters for loading external content from the file. To embed your document using this technique, follow these steps:
A single-page application (SPA) is a web technology and design paradigm that reduces browser-level page loads by using JavaScript to fetch resources and build pages. This creates a smoother, faster user experience more similar to a desktop or mobile application than a traditional web page. React and Angular are two popular JavaScript frameworks used to create SPAs.
When a user navigates to a SPA, the initial page download is considered the "base page." The base page includes the HTML skeleton, the core CSS, and the JavaScript framework for fetching and constructing new content. The ensuing pages are constructed from resources downloaded with the base page or fetched dynamically from the backend in response to user interaction. This new content (or views) constructed from different sources by the SPA are called "virtual pages."
Until 4.4.3, Browser RUM only provided auto-instrumentation for AngularJS 1 SPA applications. For other frameworks, you had to manually report events with the JavaScript Agent API. This limited auto-instrumentation for SPA is known as SPA1 monitoring.
In general, you are highly recommended to use SPA2 monitoring. For most applications, the JavaScript Agent using SPA2 monitoring identifies the SPA transitions deterministically and captures the metrics and resources correctly without you having to write any special configuration or call methods from the JavaScript Agent API. If your SPA applications are built with AngularJS 1, you can simply add some configuration to enable auto-instrumentation.
To access the Snapshot Details dialog shown below, you double-click one of the browser snapshots in the Browser Snapshots page. The Summary tab is the default tab for the dialog, and it gives some additional information such as the parent page URL.
The Pages & AJAX Requests page as shown below enables you to view the number of requests for each type of page and the average metrics per page. You can also select which page types to view, such as virtual pages.
From the Pages & AJAX Requests page, you can double-click a page to view the Page and IFrame Dashboards. Dashboards for each page type will have a Summary section displaying the average metrics as well as a Key Performance Times section showing the requests and the metrics on a timeline.
By now you should really be getting the hang of embedding things into your web pages, including images, video and audio. At this point we'd like to take somewhat of a sideways step, looking at some elements that allow you to embed a wide variety of content types into your webpages: the , and elements. s are for embedding other web pages, and the other two allow you to embed external resources such as PDF files.
In this article we are going to jump straight into an active learning section, to immediately give you a real idea of just what embedding technologies are useful for. The online world is very familiar with YouTube, but many people don't know about some of the sharing facilities it has available. Let's look at how YouTube allows us to embed a video in any page we like using an . 2ff7e9595c
