Docs: Intercepting Routes Diagram Lacking One Page.tsx file.
Showing the link in app/feed/page.tsx would make the example clearer. It navigates to the photo URL; it isn’t a redirect: // app/feed/page.tsx import Link from 'next/link' export default function FeedPage() { return ( Feed Open photo ) } With the @modal/(..)photo/[id] route and...
App Router: history traversal restores the expected router tree but an incorrect URL after entering through an HTTP 307 redirect in Android WebView
...Observed event order The following sequence is a normalized summary of one instrumented failing run, not a raw log. Times are relative to the captured form-value commit; paths and identifiers are anonymized. | Relative time | Observation | | --- | --- | | T+0 ms | The picker...
Default 'use cache' handler keeps a 64 KB buffer-pool slab alive per small entry, so cacheMaxMemorySize undercounts memory
...are affected? `next start`, standalone output (`node server.js`) ### Additional context Workaround: a custom `cacheHandlers.default` that copies each value into its own `Uint8Array` before storing it. With it, the same load left about 7 MB of the churn-phase allocations alive...
Middleware body clone hands route handlers only the tail of a multi-chunk body (Node runtime, 15.5.27)
...numbers are from 15.5.27; my local copy is 15.5.24 with the same calls at 1257 and 648. Workaround: exclude the route from the matcher and resolve inside the route whatever middleware used to provide. `experimental.middlewareClientMaxBodySize` is not involved; these bodies are...
Docs: Outdated file paths in documentation.
### What is the documentation issue? At Global Styles section, the code snippet imports `global.css` from `/app/ui/global.css`, but default conventions nowdays store globals at `/app/globals.css` ### Is there any context that might help us understand? code snippet in the docs:...
notFound() serves an empty body in production; an unmatched URL serves not-found.tsx
### Link to the code that reproduces this issue Minimal reproduction, App Router, four lines: With `app/not-found.tsx` present, run `next build && next start`, then: ### To Reproduce 1. Add the page above and any `not-found.tsx`. 2. `next build && next start` (production - this...
searchParams promise throws "TypeError: The .constructor property is not an object" when a query key is named `constructor`
### Link to the code that reproduces this issue No repository needed - the minimal reproduction is a 6-line Node script (below), because the crash is native V8 behavior triggered by how Next.js constructs the `searchParams` promise. ### To Reproduce 1. Any App Router page that...
Cache Components: app-shell prefetch (next-router-prefetch: 3) misses 'use cache' calls keyed on a root param, with no fill ever attempted
### Link to the code that reproduces this issue None yet. This is observed and fully traced (stack frames, debug logs, three independent builds - see below) in a private production app, but I have not yet isolated it into a standalone public repo - see "Isolation attempt" below,...
