Regardless of how good your website is, no visitor will stay on your site if it takes too long to load. The website should not take more than 3 seconds to load. Or else, the site will lose half of its visitors.
Are you searching for the right solution to load your website faster and improve your customers base? If yes, then you can make use of the progressive rendering. It helps you drastically enhance your website or web application’s page load time.
Do not think that progressive rendering increases the page load speed alone because it addresses specific significant issues in the server-side rendering and client-side rendering methods. Do you want to know more about progressive rendering in HTML? Keep reading.
Progressive Rendering In HTML – What To Know.
Progressive rendering is the technique for progressively updating small sections of the web pages and sites and then streaming it to the end-users in segments instead of waiting to display the whole page. The technique is also called progressive server-side rendering.
It indicates that once the restorative material is produced on the server, you can stream it to the client without waiting for the unimportant stuff. It combines the pros of both CSR (client-side rendering) and SSR (server-side rendering).
In short, progressive rendering is the technique accessed to enhance the website’s performance. To be more specific, the process maximizes the perceived load time to quickly provide the content for display.
You can implement the progressive rendering for your webpage to grab more benefits. If you want to learn deeper about progressive rendering in HTML, you should learn about CRS and SSR.
Server-Side Rendering (SSR)
SSR is how the entire HTML renders on the server and sends to the client. It is what Next.js does. The content you require to display on the screen is available once the HTML is parsed. Therefore, the first content loads faster than the CSR. Here are the steps explaining the working of SSR in detail.
- In SSR techniques, the browser requests the HTML from the server. Then, the server makes the API requests and provides the HTML content on itself.
- After that, the complied HTML is sent to the browser. As soon as the browser loads and parsers the HTML, the website is accessible to the end-user. It occurs without leaving the users to wait for the JS bundles to load.
- Then, the browser downloads and executes the JS bundles appropriately to make the website look interactive. Finally, the SSR technique eliminates the need to wait longer for page loading.
Since the APIs are co-located within the server, and initial JavaScript does not block the content, the initial content will load super fast in server-side rendering.
Even though you obtain the fast first contentful paint in SSR, the page is not interactive until the completion of the download and execution of the JS bundles on the browser.
Benefits
- Both browsers and search engines do not need to depend on JavaScript for the content anymore because the server serves HTML with the content.
- Compared to client-side rendering, the page loads much faster.
- When loading the JS (JavaScript) bundle, the content does not block.
Client-Side Rendering
Client-side rendering is the technique where the content renders in the browser with the help of JavaScript. The server sends the simple HTML without content in the body and script tags in the head. Here is how CSR works!
- Whenever the user navigates to the website, they initiate a request to get the HTML document.
- So, the server sends the HTML with the script tags to download and access the JS bundle with the empty body.
- After that, the browser parses the HTML and allows HTTP requests to fetch the JS bundle. Now, the user will see the HTML shell’s partial content as the loading indicator or blank page.
- Once the main JS bundle fetches and loads, the users will be able to see the real and meaningful content.
As soon as the initial JS loads in CSR, the content will load asynchronously. It helps you load the critical content first and then the non-critical content. The technique benefits the users by caching static HTML and the initial loaded JS bundles in the web browser. Thus, the navigation between the pages turns super fast and effortless.
But, users need to wait until the entire JS bundle finishes downloading and executing to see the content. Or else, they need to watch the blank screen without updating what’s occurring currently. If the bundle size goes up, users need to wait more before seeing anything meaningful.
Benefits
- The content will load asynchronously as soon as the initial JS loads. It means you can load the critical content prior.
- The server serves the static HTML and initial load JS bundles to cache in the browsers to benefit frequent users.
Progressive Server-Side Rendering [PSSR]
Did you know that progressive server-side rendering is a key to faster website loading? It is a technique of rendering the part of the web pages sequentially on the server-side. Later, it sends to the client in portions without the need for waiting longer to load the entire page.
PSSR is wholly based on the HTML streaming concept. It breaks the pages into meaningful and understandable components with the help of code splitting. The separate script controls those pieces of the web pages. Here is the working of the PSSR.
- As usual, the browser requests the server for HTML, and the server makes the API requests.
- Then, it renders the main content to the server and then streams the content to the browser.
- After the browser receives the chunk of HTML, it renders the content on the screen. Upon generating the vital data and streams to the client, the server provides the non-critical content.
- Finally, the browser receives and paints the non-critical content.
PSSR renders the benefits of both SSR and CSR. So, you can use the progressive rendering in HTML to attract more users with enhanced page loading time and performance.
