Next.js and Gatsby support SSR, SSG, ISR/DSG, and RSC. So, the more rendering methods are available to you, the better you can optimize your website for various behavior scenarios. You don’t have to pick a single rendering method for the whole website. How do the frameworks compare on rendering methods?

Our agency can help you decide between frameworks You can combine RSC and SSR in the hydration phase to achieve partial hydration. That way, the JS bundle shipped to the client gets much smaller than in CSR, the data doesn’t get stale as in SSG, and the page doesn’t take much time to load. Server component updates are also rendered on the server and sent to the client in a JSON-like format. How does it work? The components that interact with other APIs are generated on the server, and others are rendered in the browser. The objective of RSC was to make the client and the server collaborate on rendering. Two years ago, React introduced React Server Components (RSC). Gatsby introduces deferred site generation (DSG), which tackles the issue of inconsistent data in big websites, but at the price of data getting stale: all the data is cached upon build time, and when item pages are re-rendered, they refer to this data layer. The main page is re-rendered upon consequential builds (once a day or even rarer), and item pages are re-rendered upon timeout (seconds or minutes). There is an issue, however: the data displayed on the main/grid page and the item page may diverge. This mechanism, called Incremental static regeneration (ISR), helps to profit from SSG without pages getting stale for a long time. If the following request comes after the timeout, the page will be re-rendered and saved again. Next.js introduces one more trick: when a page is generated upon request, it is saved for a predefined amount of time. If you want to build an extra-large website like Aliexpress, you may combine SSR and SSG: pre-render a small quantity of the pages and render the others upon request. Incremental static regeneration/Deferred static generation So, in SSG, pages are served faster! But they may become stale and won’t be refreshed until the next build. Upon request, a pre-rendered page is retrieved from the storage or a content delivery network (CDN) and served to the client. Conversely, all website pages are rendered upon build time at once in SSG. In SSR, each page is generated anew upon request, which takes time. There are many reasons to avoid client side rendering (CSR) and pick server-side rendering (SSR) or static site generation (SSG) instead. Different rendering methods optimize load latency for different page scenarios.įirst, let’s recap what’s there on the scene and then see how the meta-frameworks compare to rendering methods! Server side rendering/Static site generation When comparing meta-frameworks, they first consider the rendering methods they support. That’s why pre-built components are tailored to minimize developers' input. Your meta-framework won’t gain popularity if it doesn’t offer ease of development. Then, developer experience has great importance. Otherwise, your clients will experience delays, and you’ll fail to provide for their needs. What happens if your service becomes extremely popular in a short time? It needs to be easily scalable. So, most modern meta-frameworks were built with performance in mind. Your website should be fast to load, even on the slowest connection, and easy to navigate. When choosing a front-end meta-framework, you should remember that the contemporary web's main priority is excellent user experience.
