Fix ChunkLoadError: Loading Chunk Failed in Next.js

Fix Dynamic Server Usage Error in Next.js App Router

Technology

Fix Dynamic Server Usage Error in Next.js App Router

Next.js throws this when a route it wants to render at build time calls a dynamic function — cookies(), headers(), searchParams, or a no-store fetch. The fix is either opt the route into dynamic rendering, or remove the request-time dependency if it should be static.

Fix next/image Hostname Not Configured in Next.js

next/image strictly allow-lists remote hosts. The fix is images.remotePatterns in next.config — matched exactly on protocol, hostname, port, and pathname. Get one wrong (http vs https, a subdomain, a missing port) and it still blocks.

use client vs use server in Next.js: The Real Difference

The #1 misconception in the App Router: "use server" is not the opposite of "use client". One marks a client boundary in the module graph; the other exposes callable server functions. Server Components are the default — no directive needed.

Select the First Row per Group in Supabase Postgres

The "greatest-N-per-group" problem: one representative row per group. Postgres solves it with DISTINCT ON; supabase-js can't express that directly, so you wrap it in a view or an RPC function. Both confirmed by Supabase maintainers.
