The most prominent technique currently being used is Ajax. On subsequent requests, your single page application will, of course, use the regular client-side rendering ensuring that the content loads fast for both the first and for the umpteenth times. Most of the logic is executed on the server, and HTML is usually also rendered on the server. The client page sends data representing its current state to the server, usually through Ajax requests. Once an initial connection has been established, an event stream remains open until closed by the client. However, merely sharing templates typically requires duplication of business logic used to choose the correct templates and populate them with data. Replacing an entire template might also disturb a user's selection or cursor position, where updating only the changed value might not.

  • It uses Ajax to achieve this feel with some of its components when they're already loaded, but generally everything is reloaded when you change the URL - with the exception of Facebook pages.

    Facebook uses the OpenGraph tags defined on your page to populate its share dialogs. But what if you have a single-page app and you want. A single-page application is an app that works inside a browser and does These are, for instance: Gmail, Google Maps, Facebook or GitHub.
    We built it because we thought that other libraries made user interface programming unnecessarily difficult and confusing.

    Single Page Applications have a slower first page load than server-based applications. 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. There are some ways of speeding up the initial load of an SPA, such as a heavy approach to caching and lazy-loading modules when needed.

    An SPA moves logic from the server to the client, with the role of the web server evolving into a pure data API or web service. Server-sent events SSEs is a technique whereby servers can initiate data transmission to browser clients.

    The client page sends data representing its current state to the server, usually through Ajax requests. This architectural shift has, in some circles, been coined "Thin Server Architecture" to highlight that complexity has been moved from the server to the client, with the argument that this ultimately reduces overall complexity of the system.

    Both of these do require quite a bit of effort, and can end up giving a maintenance headache for the large complex sites.

The page does not reload at any point in the process, nor does control transfer to another page, although the location hash or the HTML5 History API can be used to provide the perception and navigability of separate logical pages in the application.

    These applications benefit from advances available with HTML5.

    The term “single page application,” or SPA, is used to characterize a scrolled through your Facebook news feed, or looked up directions.

    Developers can decide which page states must be crawlable by web spiders for SEO and be able to generate the required state at load time generating plain HTML instead of JavaScript.

    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.

    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. The client page sends data representing its current state to the server, usually through Ajax requests. Such templates can be rendered from different host languages, such as Ruby on the server and JavaScript in the client.

    Use cases include applications that surface private data hidden behind an authentication system.

    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. In an SPA, either all necessary code — HTMLJavaScriptand CSS — is retrieved with a single page load, [1] or the appropriate resources are dynamically loaded and added to the page as necessary, usually in response to user actions.

    The question of performance and wait-times remains a decision that the developer must make. Blogs, support forums, and other traditional page redraw artifacts often sit around the SPA that can seed search engines with relevant terms.

    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.

    1. If you put enough effort into making your SPA crawlable, you can make it as SEO-friendly as any traditional web application. 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.

    2. Mature open-source libraries are available that support the building of an SPA, reducing the amount of JavaScript code the developer has to write.

    3. Because "state navigation" in the same page is analogous to page navigation, in theory, any page-based web site could be converted to single-page replacing in the same page only the changed parts result of comparing consecutive pages in a non-SPA.

    4. One way to increase the amount of code that can be shared between servers and clients is to use a logic-less template language like Mustache or Handlebars.
