Here is how it works and what it affects: --- ### 1. **The first screen appears sooner** **Without SSR (CSR):** - the browser receives an empty HTML shell - it waits for JavaScript to load - then it renders the content on the client There is a delay before the text, buttons, and structure appear **With SSR:** - the server has already generated the HTML - the browser immediately draws the finished page The user sees the content almost right away **Outcome:** **First Contentful Paint (FCP)** and **Time to First Byte (TTFB)** are reduced --- ### 2. **Less work for weaker devices** In CSR: all the JavaScript loads and runs in the browser → load on a mobile device or an older computer In SSR: most of the work is done by the server → the browser only has to display the result **Result:** less lag, less loading --- ### 3. **Optimal UX: HTML first, then interactivity** The user sees the text, images, and structure right away → and JavaScript "brings the page to life" a bit later (hydration) **This creates a sense of speed**, even while background logic is still loading --- ### There is a nuance though: SSR **speeds up the first paint**, but it **can add delay** when navigating between pages if the server renders them every time. This is solved with caching and pre-rendering strategies. --- ### Conclusion: - **SSR speeds up the display of the first screen** - **Reduces the load on the client** - **Makes the site feel "alive" right away, without a gray screen** - But it requires careful setup to balance the server and the client.For the reviewerNote to the moderator (optional)Visible only to the moderator.
