How search engines crawl sites built on various JS frameworks; source: Both of these do require quite a bit of effort, and can end up giving a maintenance headache for the large complex sites. This is traditionally difficult, because the rendering code might need to be written in a different language or framework on the server and in the client. This is a variant of the stateful server approach. Although this method is outdated, asynchronous calls to the server may also be achieved using browser plug-in technologies such as SilverlightFlashor Java applets. 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. Developers can integrate them into the application and make sure that everything is working correctly, but there is no need to do everything from scratch.

    Server-sent events SSEs is a technique whereby servers can initiate data transmission to browser clients. This is because the first load has to bring down the framework and the application code before rendering the required view as HTML in the browser.

    In this approach, the server knows with precision the DOM state on the client, any big or small page update required is generated in the server, and transported by Ajax, the exact JavaScript code to bring the client page to the new state executing DOM methods. There are also potential SEO pitfalls. The most prominent technique currently being used is Ajax.

WebSockets are typically used in applications where real time updates are required. 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.

    Like What You Just Read? 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 the cases where these applications are consumer products, often a classic "page redraw" model is used for the applications landing page and marketing site, which provides enough meta data for the application to appear as a hit in a search engine query.

    2. SPAs achieve this by dynamically updating website content without reloading the whole page.

    3. 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. This is a variant of the stateful server approach.
