What is SSR (Server-Side Rendering)?

SSR (Server-Side Rendering) is a method of rendering web pages where HTML is generated on the server at the time of the request and sent to the client in a fully ready form.

Advantages:

• SEO optimization: Search engines find it easier to index content as they receive ready HTML.
• Improved performance: The initial page load is faster because the browser does not need to wait for JavaScript execution to display content.
• Better user experience on slow devices/weak connections: Users see content faster.

Disadvantages:

• Increased server load: The server spends resources generating HTML for each request.
• Slower time to interactivity: Although content is visible quickly, interactivity may only appear after loading and executing client-side JavaScript (hydration).
• Development complexity: Requires a specific architecture and development approach.
