UA sniffing. Historically, this was done with services like PhantomJS now deprecated and no longer developed, but today Puppeteer headless Chrome can perform similar functions.
Hybrid rendering - This is a long-standing recommendation from Google and is definitely the way to go for newer site builds. In short, everyone - bots and humans alike - is served the initial view as fully rendered static HTML. Crawlers can continue to request URLs this way and get static content each time, while on regular browsers JavaScript takes over after the initial page load. In theory , this is a great solution that also has a lot of other advantages in terms of speed and usability; more on this later
The latter is cleaner, does not involve UA sniffing, and is armenia mobile database Google's long-standing recommendation. It's also important to clarify that "hybrid rendering" is not a single solution - it's the result of many possible approaches to making static prerendered content available server-side. Let's analyze a few ways to achieve this result.
IsomorphicUniversal Applications
This is one way you might implement a "hybrid rendering" setup. Isomorphic applications use JavaScript that runs on both the server and the client . This is made possible by the advent of Node.js, which, among other things, allows developers to write code that can run both on the backend and in the browser.
Typically, you'll configure your framework React, Angular Universal, etc. to run on a Node server, pre-rendering some or all of the HTML before sending it to the client. Therefore, your server must be configured to respond to deep URLs by rendering the HTML for the appropriate page. In a normal browser, this is the point where the client application seamlessly takes over. The static HTML provided by the server for the initial view is "rehydrated" fancy term by the browser, which re-transforms it into a single page application and executes subsequent navigation events using JavaScript.
