Not a new trend that is not losing popularity yet. Typically, this technology is used to create websites that interact with the user by dynamically rewriting the entire page, instead of fully loading new pages from the server.
Somehow this principle can be compared with the development of computer games. The computer has at once all the information about the gaming environment. However, only the part in which the camera is turned is displayed on the screen. All that “outside the lens” has no appearance. But when transferring the camera, some textures are loaded, while others are cleared from memory.
In the case of sites, the common code will be permanently extracted, displaying key elements of the service (navigation bar, background, registration window, etc.), and the rest will be loaded and added to the page as necessary (in response to user actions).
To understand the technology, I propose to read the Hacker Rank report on the development of developer skills and upcoming programming trends.
This approach will avoid interrupting user interaction between consecutive pages. SPA spared from difficult navigation and swirling menus. They perfectly adapt to any device.
That’s why they will be relevant in 2020.
