Incremental Static Regeneration (ISR) vs Server Components

Next.js App Router has introduced new paradigms. Understanding when to use Static Site Generation (SSG), Incremental Static Regeneration (ISR), and dynamic Server Side Rendering (SSR) is crucial to keeping hosting costs low and speeds high.

For headless blogs, we highly recommend using a hybrid approach: static layouts that regenerate periodically when content edits are made in WordPress, combined with client-side interactivity for features like comment submissions and search inputs.
