| [Lazy-loaded routes](best-practices/performance/lazy-loaded-routes#lazily-loaded-components-and-routes) | Defers loading route components until navigation, reducing the initial bundle size | Applications with multiple routes where not all are needed on initial load |
| [Deferred loading with `@defer`](best-practices/performance/defer) | Splits components into separate bundles that load on demand | Components not visible on initial render, heavy third-party libraries, below-the-fold content |
| [Lazy loading services with `injectAsync`](guide/di/lazy-loading-services) | Splits rarely used services into separate chunks and loads them on demand | Services backed by large libraries or infrequently used features |
| [Image optimization](best-practices/performance/image-optimization) | Prioritizes LCP images, lazy loads others, generates responsive `srcset` attributes | Any application that displays images |
| [Server-side rendering](best-practices/performance/ssr) | Renders pages on the server for faster first paint and better SEO, with [hydration](guide/hydration) to restore interactivity and [incremental hydration](guide/incremental-hydration) to defer hydrating sections until needed | Content-heavy applications, pages that need search engine indexing |
