As long as the SPA is capable of resurrecting the same screen state from information contained within the URL hash, the expected back button behavior is retained. The difficulty comes in managing this and ensuring that everything is being tracked accurately — this involves checking for missing reports and double entries. Use cases include applications that surface private data hidden behind an authentication system. They also break HTTP referer headers as browsers are not allowed to send the fragment identifier in the Referer header. Because SEO compatibility is not trivial in SPAs, it is worth noting that SPAs are commonly not used in a context where search engine indexing is either a requirement, or desirable. Failing to call said function, the browser never triggers a new page load, nothing gets added to the browser history, and the analytics package has no idea who is doing what on the site. JavaScript can be used in a web browser to display the user interface UIrun application logic, and communicate with a web server.


  • Because the SPA is an evolution away from the stateless page-redraw model that browsers were originally. A single-page application (SPA) is a website that re-renders its content in When you navigate within an internal-state app, there is no external.

    There are many pros and cons of SPA as well as of MPA. I hope that the lines below will clear the differences between these two design.

    To avoid excessive downloading of unused features, an SPA will often progressively download more features as they become required, either small fragments of the page, or complete screen modules. Rendering from templates may have negative performance effects when only updating a small portion of the page—such as the value of a text input within a large template.

    This gives users the ability to download the SPA from a server and run the file from a local storage device, without depending on server connectivity. To avoid these problems, applications can use UI data bindings or granular DOM manipulation to only update the appropriate parts of the page instead of re-rendering entire templates. Retrieved 31 January The question of performance and wait-times remains a decision that the developer must make.

    The traditional solution for SPAs has been to change the browser URL's hash fragment identifier in accord with the current screen state. If you're already supporting a web API for use by other clients, it may require less effort to create a SPA implementation that leverages these APIs rather than reproducing the logic in server-side form.

    But it's not possible to get away from the fact that it needs to download the framework, at least some of the application code, and will most likely hit an API for data before displaying something in the browser.

    In an SPA, after the first page loads, all interaction with the server happens through AJAX calls.

    These AJAX calls return data—not markup—usually in JSON. Okay, now that I have your attention, let me say that I don't really hate your single page app.

    At the same time, this approach is more easily scalable because there is no per-client page data kept in the server and, therefore, Ajax requests can be dispatched to different server nodes with no need for session data sharing or server affinity. You can do this using the methods setCustomUrl and setDocumentTitle like this:.
