SSR involves rendering web pages on the server side before sending them to the client's browser. This is in contrast to traditional Single Page Applications (SPAs), where the rendering happens primarily on the client side.

<h2>Pros</h2>
<ul>
<li>Improved SEO: Search engines can crawl and index the content more effectively because the initial HTML is fully rendered on the server.</li>
<li>Faster Initial Page Load: SSR provides a fully rendered page to the user's browser right away, reducing the time needed to display meaningful content.</li>
<li>Better Performance on Low-End Devices: SSR is more forgiving because the server does most of the heavy lifting helping devices with limited processing power or slow network connections to load content efficiently</li>
<li>Improved User Experience: With SSR, users see content quicker, which can lead to better user retention and satisfaction.</li>
<li>Progressive Enhancement: You can progressively enhance SSR applications by adding client-side interactivity using JavaScript after the initial render.</li>
</ul>
<hr />
<h2>Cons</h2>
<ul>
<li>Complexity: Implementing SSR can be more complex than building a traditional SPA as it requires rendering logic, routing setup, and handling data-fetching on the server.</li>
<li>Server Load: SSR can put a higher load on the server compared to SPAs, especially for applications with a high volume of users.</li>
<li>Slower Subsequent Page Transitions: While the initial page load is faster, subsequent transitions between pages in an SSR application might be slower because they require full-page reloads.</li>
<li>Development Overhead: SSR can introduce additional complexity to development and deployment, potentially requiring more server-side code and build processes.</li>
</ul>
<hr />
<h2>Ideal Use Cases</h2>
<ul>
<li>E-commerce Websites: E-commerce sites often benefit from SSR because they require good SEO for product listings, and users expect quick access to product information.</li>
<li>Content Publishing Platforms: Blogs, news websites, and content-heavy platforms can use SSR to ensure their content is indexed by search engines and to provide a fast initial page load.</li>
<li>Dashboard and Admin Interfaces: For applications where the primary user base includes administrators or internal users, SSR can provide a faster and more SEO-friendly experience for content such as dashboards and reports.</li>
<li>Hybrid Approaches: Some projects opt for a hybrid approach, using SSR for critical pages that require good SEO and initial load times while using SPAs for more interactive parts of the application.</li>
</ul>
