An important step in that evolution is the development of single-page applications and the frameworks, such as Vue.js, that make them possible.
What Is a Single-Page Application?
As a result, the page never reloads or forwards to a new page. Instead, the screen is dynamically changed and updated as needed, just like a desktop application.
SPA Use Cases
Because of its ability to emulate the paradigm most people are familiar and comfortable with, SPA is ideal for complex web apps. Perfect examples are sites like Gmail, Google Maps, Twitter, Facebook and GitHub.
In each of the above cases, the web app updates, changes and adapts to what the user is doing without leaving the page or forwarding to another. For example, when a user browses Gmail, clicking on a mailbox or an individual message loads the corresponding content without the entire page redrawing and without sending them to a new page.
There are a number of advantages to this approach. Beyond the obvious advantage of simulating a desktop application, SPAs are often more responsive and faster for the user. With a traditional website or web application, there is much more data being sent back and forth between client and server. Because the server is generating HTML pages for each request, each page has the basic HTML tags and information common to all HTML pages.
As a result, a lot of duplicate information is passed to the client. While it may not be noticeable on a fast connection, on slower connections or mobile devices, that additional data can add up. In contrast, an SPA only sends the updated information, reducing the amount of network traffic. This has the added benefit of reducing the load on the server, since it doesn’t have to serve pre-formatted pages.
While it is still important for the programmer to properly code the application for optimal speed, even if there is little visible speed improvement, visual cues can be added to give the appearance of a faster, smoother experience, much like a desktop environment.
Vue.js: The New Kid On the Block
While there are several frameworks that open the door to desktop and mobile development, Vue.js (Vue) is one of the newer ones. As such, it has some positives and negatives, when compared with its competitors.
At the same time, because of its relative youth and its strong focus on speed and simplicity, Vue may not always be the best option for larger, more complex projects.
New or existing developers would do well to take a look at Vue to see how its simple, performance-based approach can help.
