Deploy server

Page load and rendering– The client downloads the HTML file and displays the static components on the page. Views for specific URLs are managed by a JavaScript routing mechanism. Each URL request triggers a DOM update instead of a network request. As a result, sites that use client-side rendering can feel “snappier” and more responsive to user actions. However, client-side rendering has two significant drawbacks. Heavier initial page load due to loading of the framework, app code, and assets required for multiple pages.

To leverage the manifest, frameworks need to provide a way to collect the module IDs of the components that were used during a server render call. Move the creation and all usage of the best  ssr server behind dev-only conditional branches, then add static file serving middlewares to serve files from dist/client. First Input Delay is the third metric of Google’s Core Web Vitals.

This function walks down the entire tree and executes every required query it encounters . It returns a Promise that resolves when all result data is ready in the Apollo Client cache. The options object in load and transform is optional, rollup is not currently using this object but may extend these hooks with additional metadata in the future. Vite.middlewares is a Connect instance which can be used as a middleware in any connect-compatible Node.js framework. The following guide also assumes prior experience working with SSR in your framework of choice, and will only focus on Vite-specific integration details.

There is nothing to load since the actual content needs to be rendered using JavaScript. For starters, instead of having the content inside the HTML file, you have a container div with an id of root. You also have two script elements right above the closing body tag. One that will load the Vue.js JavaScript library and one that will load a file called app.js. Take note of the daemon ID that is generated, as you’ll need to use this in your apps deployment script.

Http Interceptor that avoids doing duplicate requests that were already made when the application was rendered on the server. By utilizing SSR and Universal JavaScript in our app, we can do an initial render of our app on the server and send over a precompiled version before any JavaScript has been run on the client. Learn about React Server Components, an opinionated data-fetching and rendering workflow for React apps. A Suspense boundary is any portion of React component code that’s enclosed by a pair of Suspense component tags. The components in a Suspense boundary share common rendering behaviors while awaiting data controlled by Suspense. Multiple Suspense boundaries can co-exist within a single component, and Suspense boundaries can also be nested.

All URL requests are redirected to the same bare-bones HTML document, like the example that follows. Server-side rendering means using a server to generate HTML from JavaScript modules in response to a URL request. That’s in contrast to client-side rendering, which uses the browser to create HTML using the DOM. In server-side rendered pages, it is common to use snippets of jQuery to add user interactivity to each page. However, when building large apps, just jQuery is insufficient.

To see how implementing server-side rendering impacts your site speed, you’ll need to monitor everything from page speed to Core Web Vitals scores. You don’t necessarily have to choose between these two options, though. There are hybrid solutions, too, which might work better for your application. This is not really an argument against SSR, just something to keep in mind as a potential risk if it’s implemented poorly. You can test your app for HTML bloat and other issues with our free HTML size analyzer tool.

Those are the main differences between server-side and client-side rendering. Only you the developer can decide which option is best for your website or application. This is much faster since you are only loading a very small section of the page to fetch the new content, instead of loading the entire page. To fix that, you would place the following lines of code into the app.js file. If you were to make a request to the URL with only the code above, you would get a blank screen.

However, in the case of the SSR, a request is sent every time to the server. But with caching mechanism up and running, rendering speed is improved significantly. This helps browsers to retrieve the scripts from the cache memory, resulting in a performance boost. JavaScript provides end-users with a fun and interactive experience while SEO enables those users to find the right web pages. Server-Side Rendering is what makes performing both tasks possible. But with the advent of JavaScript, SSR took a backseat for a while and client-side rendering rose to fame.
