SSR
SSR (Server-Side Rendering) is a way of creating websites that helps them load faster and work better with search engines like Google. Instead of letting the user's web browser do all the work, SSR means the website's content is prepared on the server before being sent to the user. Think of it like a restaurant that serves pre-cooked meals (SSR) versus giving customers ingredients to cook themselves (client-side rendering). Companies often look for developers who understand SSR because it can lead to better website performance and help businesses appear higher in search results. This approach is commonly used with popular tools like Next.js, Nuxt.js, or React with server components.
