Whats Server Side Rendering and do I need it?

This works as expected in a pure client-side Vue application, since the modules in our application are initialized fresh for each browser page visit. Note that if a third-party library is not written with universal usage in mind, it could be tricky to integrate it into a server-rendered app. You might be able to get it working by mocking some of the globals, but it would be hacky and may interfere with the environment detection code of other libraries. During SSR, each request URL maps to a desired state of our application. There is no user interaction and no DOM updates, so reactivity is unnecessary on the server. By default, reactivity is disabled during SSR for better performance.

Instead of providing a uri option, you provide an HttpLink instance to the link option. This enables you to specify any required authentication details when sending requests to your GraphQL endpoint from the server side. Alternatively, you can eliminate long-running blocking tasks by splitting up rendering into smaller chunks. Vue has a createSSRApp() method and a corresponding best  ssr server rendering API.

In client-side rendering, the partial web page is returned by the server without dynamic data, but it offers the client-side scripts that are required to fetch the data on demand that are asynchronous. To facilitate independent deployments of our micro frontends, such that the web server does not have to reboot/redeploy every time we update every micro frontend, we can use dynamic module loading. Dynamic module loading refers to loading a module from a dynamic location – often from somewhere on disk or over the network. By default, NodeJS will only load modules from relative URLs or from the node_modules directory, but dynamic module loading allows you to load modules from any arbitrary file path or URL. Data fetching in Next.js allows you to render your content in different ways, depending on your application’s use case. These include pre-rendering with Server-side Rendering or Static Generation, and updating or creating content at runtime with Incremental Static Regeneration.

The initial page HTML is the same for all pages, so you can cache it and load it from a content delivery network along with the JavaScript code. As the largest content element is part of the static content your server pre-renders, SSR will display it faster on the screen. As a result, users see a blank screen or loading spinner for a relatively long time. This leads to a poorer user experience and higher bounce rates (see Google’s discussion of how page load time impacts bounce rates). Single-page applications are a web app architecture that appeared as an alternative to traditional websites and multi-page applications. Your bare bones HTML document lacks the keyword, description, and social media metadata (e.g. OpenGraph) necessary for search engine optimization and social media sharing.

The advantage of doing so is web app frontends are developed and delivered for users to view and interact with the page seamlessly. The only catch is that the extra burden it puts on your server, which most advanced servers can easily handle. If your GraphQL endpoint is hosted by the same server that you’re rendering from, you can optionally avoid using the network when executing your SSR queries. This is particularly helpful if localhost is firewalled in the server’s environment (e.g., on Heroku).

Now, let us create a standard Angular app using some Angular best practices that is by default development for client-side rendering. After that, we will use the new Angular schematic to configure the app as server-side rendering. One of the widely used modules used to do Server Side Rendering in Node.js is EJS Module.

It’s possible and valid for your GraphQL endpoint to be hosted by the same server that’s performing SSR. In this case, Apollo Client doesn’t need to make network requests to execute queries. Before Vite 2.7, this was informed to plugin hooks with a positional ssr param instead of using the options object. All major frameworks and plugins are updated but you may find outdated posts using the previous API.
