These are some of the key features provided by a competitive SPA nowadays:
- No server-side roundtrips: A competitive SPA is able to redraw any part of the client UI without requiring a full server-side round trip to retrieve a full HTML page. This is mostly achieved by implementing a Separation of Concerns design principle, which means that the data will be separated from the presentation of data using a model layer that will handle the former, and a view layer that reads from the latter.
The list can easily grow, as these are only some of the major advantages of a properlydesigned, competitive SPA. These aspects play a major role nowadays, as many business websites and services are switching from their traditional Multi-Page Application mindset (MPA) to full-committed or hybrid SPA-based approaches. The latter ones, which have been increasingly popular since 2015, are commonly called Native Web Applications (NWA), because they tend to implement a number of small-scale, single-page modules bound together upon a multipage skeleton rather than building a single, monolithic SPA.
Not to mention the fact that there are also a lot of enterprise-level SPAs and Native Web Applications flawlessly serving thousands of users every day, want to name a few? WhatsApp Web and Teleport Web, Flickr, plus a wide amount of Google web services, including Gmail, Contacts, Spreadsheet, Maps, and more. These services, along with their huge user base, are the ultimate proof that we’re not talking about a silly trend that will fade away with time; conversely, we’re witnessing the completion of a consolidated pattern that’s definitely meant to stay.
