▸case-01 I have an existing Next.js project using the Pages Router with getStaticProps and custom API endpoints. I want to upgrade to Next.js 14. Please provide a clear breakdown of how to restructure my file directory, refactor the data-fetching logic to leverage Server Components, and convert API handlers to Server Actions. | fail→fail | 20,700 | 23,985 | +16% | 1 | 1 | 0% | 4,031 | 4,403 | +9% | 0 | 0 | — |
▸case-02 I am building a photo gallery feed in Next.js 14 where clicking an image opens it in a overlay modal while preserving the background page context, but navigating directly to the photo URL renders a standalone page.
