Server-Side Rendering means your HTML pages are built on the server for each request, with all the data already included when they reach the browser. Think of it like ordering a custom sandwich - it's made fresh for you right when you order it.
- User requests a page
- Server fetches all necessary data
- Server renders complete HTML with content included
- Fully-formed page is sent to browser
- JavaScript "hydrates" to add interactivity
- Fast initial load - Users see content immediately
- Perfect SEO - Search engines get complete HTML content
- Fresh data - Content is always up-to-date since it's fetched per request
- Works without JavaScript - Basic functionality available even if JS fails
- Good for slow devices - Less processing required on the client
- Slower navigation - Each page requires a server round-trip
- Server complexity - Need to maintain server infrastructure
- Higher hosting costs - Requires actual servers, not just static hosting
- Potential bottlenecks - Server can become overwhelmed with requests
- Slower Time to Interactive - May show content before it's fully interactive
- E-commerce sites (product pages, checkout)
- News and content websites
- Social media platforms
- Apps where fresh data is critical
- Sites that need both SEO and dynamic content
- Highly interactive apps (games, complex dashboards)
- Apps with mostly static content (use SSG instead)
- Projects with limited server budget
- Apps where every millisecond of interaction speed matters
