chore: update dependencies, migrate to TypeScript 7, pin Node 24 - #58
Conversation
Remove frontend-design and feature-dev. Add mattpocock-skills, disabled: enabled plugins add always-on context to every session, so they stay off until actually used. README previously documented settings.json as permissions only. It now names it as the plugins file too, and warns that cloning the template installs my marketplaces and plugins into the clone. Also drops the Ngrok note from Quick Notes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com>
Link text now matches its target so readers can locate a file without hovering; directories keep a trailing slash. External links and image alt text unchanged. Step 7 drops counter.tsx (no such file in the repo) and qualifies the rest with their app/ or components/ directory. Adds a quick note on why some plugins sit at false in settings.json.
The markdownlint-cli2 bump is load-bearing, not routine. MD060 had no fix data before markdownlint 0.41.1, so `--fix` could report the 84 table-delimiter violations but never repair them, and the old `^0.22.1` range could not reach the release that bundles it. MD028 and MD036 stay off deliberately. Enabling them would merge distinct attributed quotes into single blockquotes and force bold pseudo-headings like "Step A:" into real headings — both are intended prose patterns, not oversights. Table reformatting and the added H1s are mechanical fallout from turning the rules on. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The template ships no .mdx files and no MDX tooling, so the recommendation prompted contributors to install language support for a format this repo never uses. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The project overview restated the README and would drift from it. CLAUDE.md loads into every session, so anything the README already answers is context spent for nothing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Runs `npm update`, taking every package to the newest version its existing caret range already permitted. No range widening — npm 12 rewrites the floors to match what it installed. next 16.2.6 -> 16.3.0 react/dom 19.2.6 -> 19.2.8 biome 2.4.15 -> 2.5.8 playwright 1.60.0 -> 1.62.1 tailwind 4.3.0 -> 4.3.3 vitest 4.1.6 -> 4.1.10 lefthook 2.1.6 -> 2.1.10 plus @types/*, user-event, @vitejs/plugin-react Two follow-on changes were required: Biome 2.5 lints standalone .svg files, so a11y/noSvgWithoutTitle failed on all five stock assets in public/. Excluded public/ from Biome — it holds build assets, not source, and the referenced SVGs already carry alt text via next/image. Inline SVGs in .tsx remain linted. Also ran `biome migrate` for the 2.5.8 schema and the recommended -> preset rename. Next.js 16.3 generates AGENTS.md on `next dev`, pointing agents at the version-matched docs in node_modules. Committed, because its generator upserts between markers only when AGENTS.md exists — so version bumps land as a small tracked diff rather than a recurring untracked file. The bridge lives in .claude/CLAUDE.md as @../AGENTS.md, keeping the repo root free of a generated CLAUDE.md. Gates: check, test:unit, test:e2e, build, lint:md all green.

Bumps typescript ^6.0.3 -> ^7.0.2, the Go port. Next.js 16.3 added support for it in `next build`, so the two land together. Type checking in `next build`: 1276ms -> 242ms (5.3x faster). Standalone `tsc --noEmit` completes in 0.36s wall at ~350% CPU — the native compiler parallelises where tsc 6 was single-threaded. Nothing in the codebase needed changing. The three classic TS 7 breakages did not apply: no baseUrl, esModuleInterop already true, moduleResolution already "bundler". target ES2017 was reviewed and left as-is — TS 7 accepts it and it matches create-next-app. TS 7.0 ships no stable JS compiler API (that lands in 7.1), which is what breaks typescript-eslint, ts-morph and similar. This stack is unaffected: Biome parses TypeScript in Rust, Vitest transforms via esbuild, and Playwright has its own transpiler. No package here imports the compiler API. The compiler is now a platform-specific native binary. All 20 @typescript/typescript-* variants are recorded in the lockfile — including darwin-arm64, darwin-x64 and win32-x64 — so `npm ci` resolves correctly for template users off linux. Gates: check, test:unit, test:e2e, build, lint:md all green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Follow-up to the TypeScript 7 migration, tightening three config
details that the upgrade exposed.
Adopt ESM ("type": "module"). Silences Vitest's warning that
`configLoader: 'native'` — planned to become the Vite default — cannot
load vitest.config.ts as CommonJS, and per the Next.js TypeScript docs
lets next.config.ts use native ESM (top-level await, dynamic import).
Migration cost was nil: postcss.config.mjs was the only non-TypeScript
module file and is already explicit ESM. There are no .js files.
Bump tsconfig target ES2017 -> ES2022. Functionally inert — noEmit
means tsc emits nothing (Turbopack/SWC transpiles, driven by
browserslist) and `lib` is set explicitly, so target selects no type
library. It is a coherence fix: `lib: esnext` and `target: ES2017`
contradicted each other, and in a template the config is the product.
Document why typescript.tsdk stays unset. TypeScript 7 ships no
tsserver — its bin is `tsc` alone and the package's main export is a
version stub — so "TypeScript: Select TypeScript Version -> Use
Workspace Version" disables IntelliSense outright. VS Code's bundled
tsserver is what loads the Next.js language-service plugin declared in
tsconfig.json, powering typedRoutes and 'use client' checks, while
`tsc` handles CLI and build type checking. The Next.js docs still
recommend the workspace switch; that guidance predates TS 7.
Gates: check, test:unit, test:e2e, build, lint:md all green.

Both majors live entirely in the Vitest lane, so they land together. jsdom 30's only breaking change is a raised Node floor (^22.22.2 || ^24.15.0 || >=26.0.0); the rest is additive — CSS.escape(), CSS.supports(), and a getComputedStyle() fix converting lengths to pixels. jest-dom 7 makes @testing-library/dom a required peer dependency, so it is now declared explicitly rather than relied on via hoisting from @testing-library/react. Adds an engines floor of Node >=24.15.0. That is where jsdom 30 supports the Node 24 line, and it matches both the local runtime and CI's lts/*. npm now warns at install time instead of failing opaquely at runtime. Adds components/button.test.tsx. The existing suite only covered a pure function, so a green run proved nothing about jsdom or jest-dom — the upgrade was unverifiable with the tests as they stood. This renders a component in jsdom and asserts through jest-dom matchers (toBeInTheDocument, toHaveAttribute, toHaveTextContent, toBeVisible, toHaveClass), confirming both matcher registration and the TypeScript matcher types resolved via tsconfig's types array. It doubles as the worked React Testing Library example the template was missing, and is marked deletable in the same style as lib/formatPrice.test.ts. Gates: check, test:unit (8 tests), test:e2e, build, lint:md all green. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Downgrades @types/node ^25.9.5 -> ^24.13.3. This is the one package in the upgrade where "latest" is the wrong answer. @types/node major versions track Node.js major versions, so the version should follow the runtime, not the registry. This project runs Node 24.18.0 locally and lts/* in CI, which resolves to the same Node 24 "Krypton" line — the current Active LTS. Node 26 exists but is a Current release and does not reach Active LTS until 2027; Node's own guidance is to run Active or Maintenance LTS in production. Sitting on @types/node 25 (and more so 26) meant type-checking against APIs the runtime does not have, which the compiler would happily allow. Resolution stays a single hoisted copy: vite and vitest both declare @types/node as an optional peer with wide ranges (>=22.12.0 and >=24.0.0), and vitest itself develops against ^24.12.0, so ^24 satisfies the tree with no nested duplicate — which would otherwise put two sets of Node types in one program. Also tells Dependabot to skip @types/node majors. Without it the bot raises a PR to undo this every time Node's types advance, and the rationale lives only in this commit message. The pin is now enforced by config and revisited deliberately at the next LTS. Gates: check, test:unit, test:e2e, build, lint:md all green.

CLAUDE.md loads into every session, so each line has to pay for itself. The breaking-changes list drops from five notes to two. Tested each against Next.js 16.3: segment configs, the Suspense rule and middleware.ts all fail or warn at build with a better message than the note gave. Only the sync `params` form is genuinely invisible — it passes typecheck and build, then renders undefined. The heading now states that inclusion test, so the list stays filtered rather than accumulating. Versions drop out of the stack list except where they change how code gets written, since a stale number in agent context is worse than none — it can suppress an API that does exist. README keeps fuller numbers, being read once by a human where they signal a current template. Both files gain a Node row now that package.json declares an engines floor.

c055546 excluded public/ wholesale to silence a11y/noSvgWithoutTitle on five stock SVGs, leaving anything else landing there — robots.txt, a webmanifest — silently unchecked. Adding a <title> to each SVG removes the need for any exemption, so biome.json drops the negation rather than trading it for a rule-level override. Gates: check, test:unit, build, lint:md green. test:e2e not run. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The four workflows used node-version 'lts/*', which resolves at run time: the moment Node 26 becomes Active LTS, CI silently moves while @types/node stays pinned to 24 (commit 9c4fb76) and the Dependabot ignore suppresses the PR that would flag it — recreating the exact runtime/types divergence that pin exists to prevent. Vercel drifts the same way: it picks the newest Node satisfying engines, and ">=24.15.0" is an open floor. .nvmrc is now the single source of the Node major. CI reads it via node-version-file; the engines upper bound keeps Vercel on 24 and makes npm warn on mismatched local Nodes. Moving to the next LTS is one deliberate step: raise .nvmrc, engines, @types/node and the Dependabot ignore together. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Inline comments:
In @.claude/CLAUDE.md:
- Around line 21-28: Update the “Traps Tooling Does Not Catch” section
introduction to cover mistakes that lint, typecheck, or build checks fail to
catch clearly, so the Tailwind v4 guidance remains in scope while preserving the
existing dynamic route params and Tailwind examples.
In @.nvmrc:
- Line 1: Update the .nvmrc Node.js version from 24 to 24.15.0 so the local
runtime matches the package.json requirement and avoids selecting an older
incompatible Node 24 release.
In `@README.md`:
- Line 44: Reconcile the housekeeping guidance with the README references to
xdocs: either move the referenced images and project-setup documentation outside
xdocs while updating the links, or revise the removal instruction to require
updating all affected README links and image references at the same time.
Preserve valid README assets and setup links after the cleanup.
- Line 60: Update the TypeScript 7 performance claim in the README table: either
document the measured TypeScript versions, workload, and hardware supporting
“~5x faster,” or replace it with qualitative wording or a citation to benchmark
context; do not present the unqualified figure as universal.
- Around line 269-273: Update the “Claude Code Plugins” section to use /plugin
consistently, clarify that a false enabledPlugins entry disables a plugin
without establishing that it is installed, mention that enabled plugins may add
always-on listing tokens and components can incur on-invoke costs, and change
the details command to use the plugin name without a marketplace suffix.
In `@xdocs/own/agentmd-over-skills.md`:
- Line 15: Update the publication date metadata for the linked Vercel source in
the SOURCE entry to 27 January 2026, leaving the URL and surrounding
documentation unchanged.
In `@xdocs/own/WORDS.md`:
- Around line 105-118: Separate the two Page examples into distinct labeled code
blocks or files so each block contains only one export default declaration;
preserve the cached and no-store fetch variants.
- Around line 120-127: Define or import a minimal fetcher for the useSWR call in
the Page component, ensuring it accepts the request URL and returns the parsed
response data so the example type-checks when copied.
- Around line 15-20: Update the dynamic route example to use userid consistently
as the params key and destructured variable, matching the [userid] segment;
remove the duplicate /users/[userid] path from the route examples.
- Line 5: Revise the Client Component guidance in WORDS.md to recommend use
client only when state, event handlers, or browser APIs are required; clarify
that navigation and form submission alone do not require a client boundary, and
state that Client Components are pre-rendered on the server during the initial
load rather than rendered exclusively in the browser.
- Around line 90-118: Update the Next.js 16 guidance in the terminology section
to target the repository’s cacheComponents configuration: state that routes are
dynamic by default and plain fetch() is not cached, retain CSR/SSR/ISR and
revalidation terminology, and correct the examples and explanations for cache,
revalidate, dynamic, 'use cache', and cacheLife behavior.

actions/setup-node node-version-file major version 24 check-latest false cached version resolution semver
💡 Result:
When using actions/setup-node with node-version-file, the action reads the specified file (such as.nvmrc,.node-version, or package.json) to determine the requested Node.js version [1][2]. If both node-version and node-version-file are provided, the node-version input takes precedence [1][3]. Regarding version resolution and caching: 1. Version Resolution: The action parses the content of the node-version-file to extract a version specifier [3]. For example, if using package.json, it looks for volta.node or engines.node [4]. 2. SemVer and check-latest: The check-latest input (which defaults to false) determines whether the action verifies if a newer version exists that satisfies your specified version range [1][2]. - With check-latest set to false, the action prioritizes stability by first searching the runner's local cache for a version that satisfies the resolved SemVer [1][2]. - If a matching version is found in the local cache, that version is used [1][2]. - If no match is found, the action proceeds to download a version [1][5]. It first attempts to fetch from actions/node-versions and falls back to the official Node.js distribution (nodejs.org/dist/) if necessary [1][2][6]. 3. Major Version 24: If your file or configuration specifies major version 24, the action treats this as a SemVer specifier [2]. With check-latest false, it will use the newest cached version of Node.js 24 available on the runner [1][2]. If no 24.x version is cached, it will download the latest available 24.x release [1][2]. In summary, setting check-latest to false instructs the action to prefer cached versions over checking for potentially newer releases, ensuring consistent builds by avoiding unexpected updates to the Node.js runtime [1].

TypeScript 7 announcement typical 8–12x full-build speedups benchmark
💡 Result:
TypeScript 7.0 was officially released on July 8, 2026, featuring a ground-up rewrite of the compiler in Go [1][2][3]. Microsoft announced that this native port, which leverages shared-memory multithreading, typically yields full-build speedups ranging from 8x to 12x [1][4][5]. Official benchmarks provided by Microsoft demonstrate these significant performance gains across several large open-source codebases [1][2]: | Codebase | TypeScript 6.0 | TypeScript 7.0 | Speedup | |:--- |:--- |:--- |:--- | | vscode | 125.7s | 10.6s | 11.9x | | sentry | 139.8s | 15.7s | 8.9x | | bluesky | 24.3s | 2.8s | 8.7x | | playwright | 12.8s | 1.47s | 8.7x | | tldraw | 11.2s | 1.46s | 7.7x | Microsoft also introduced new configuration flags to further tune performance, such as --checkers to control the number of type-checking workers [6][5]. In their testing, utilizing --checkers 8 allowed for even higher speedups, such as improving the vscode build time to 7.51 seconds (a 16.7x increase) [1][5][7]. While the "8–12x" range is the official metric, independent analysis suggests that actual results vary significantly based on codebase size, type complexity, and hardware resources [8][9][7]. Some real-world implementations have reported more modest gains (e.g., 3x–7.3x) on particularly type-heavy or complex monorepos, noting that total build time is often influenced by factors outside of type-checking, such as bundling and code generation [8][9]. Additionally, users are advised to balance the --checkers configuration with available system memory to avoid performance degradation due to resource contention [6][9].

Qualify the TypeScript performance figure.
If ~5x faster comes from a repository measurement, state the TypeScript versions, workload, and hardware. Otherwise, use qualitative wording or cite benchmark context because TypeScript 7 speedups vary by workload; published full-build examples typically report 8–12× gains.

Claude Code targeted version plugin command /plugin versus /plugins enabledPlugins false installation claude plugin details token cost always-on on-invoke official documentation
💡 Result:
In Claude Code, plugins provide a mechanism to extend functionality using custom skills, agents, hooks, and MCP servers [1][2][3]. Below are the details regarding the plugin system configuration and management. Plugin Commands: /plugin vs /plugins The primary command is /plugin [4][5]. - /plugin: When run without arguments, this opens an interactive plugin management menu (TUI) where you can discover, list, install, enable, or disable plugins [4][6][7]. - claude plugins: This is an alias for the shell command claude plugin, which is used for non-interactive scripting and management outside of an active Claude Code session [5][8]. EnabledPlugins and Installation The enabledPlugins setting in.claude/settings.json tracks whether a plugin is active [6][7][9]. - enabledPlugins false: Setting a plugin to false in your configuration is intended to disable it [6][7][10]. However, users have reported instances where this configuration may be ignored or where plugins persist despite being set to false [10]. - Installation Scopes: Plugins can be installed with user, project, or local scopes [2][8]. Project-scoped plugins are managed within.claude/settings.json, allowing them to be shared across teams when committed to a repository [8]. Token Cost and Plugin Details - Before installing a plugin, the interactive /plugin interface displays details about what the plugin will install [3]. - This interface provides an estimate of the context or token cost associated with the plugin [3]. - Users are advised to review these details carefully, as third-party plugins execute code with the user's privileges [3]. Always-On vs. On-Invoke - Plugins generally run within the context of your Claude Code session once enabled [3]. - Some plugins may include hooks or monitors that operate in the background, while others provide specific skills or agents that are triggered only on-invoke (e.g., when a user executes a specific command like /my-plugin:skill) [1][3]. - Developers can configure a plugin to ship as disabled by default by setting defaultEnabled: false in the plugin.json manifest [11]. Users can subsequently enable these plugins via the /plugin menu or the CLI [11]. Plugin Development and Testing - For development, you can load a plugin locally using the --plugin-dir flag when starting Claude Code [1][5][8]. This does not require an installation step and allows for testing before formal distribution [1][11]. - If you make changes to a plugin during development, you can use the /reload-plugins command to refresh the loaded components without restarting the Claude Code session [1][4].

site:code.claude.com/docs/en "claude plugin details" plugin details name marketplace
💡 Result:
Claude Code features an integrated plugin system that allows users to extend the agent's capabilities—such as adding skills, agents, hooks, and external tool integrations (MCP)—through installable plugins [1][2][3]. Marketplace Details Claude Code utilizes a decentralized marketplace model for plugin distribution rather than a single, monolithic store [4][3]. Key details include: 1. Official Marketplaces: Anthropic maintains an official, curated marketplace (claude-plugins-official), which is automatically registered when you first start Claude Code interactively [5][6]. There is also a community marketplace (claude-community) that users can manually add [6]. 2. Adding Marketplaces: Users can add, remove, or update marketplaces using the command /plugin marketplace add [5][4][7]. 3. Custom Marketplaces: Teams and developers can create and distribute their own marketplaces by hosting a marketplace.json file in a Git repository (e.g., GitHub or GitLab), allowing for private or team-specific plugin distribution [4][6]. 4. Management: Plugins can be managed via the CLI, the Claude Desktop app, or the VS Code extension [8][7]. In the CLI, the /plugin command opens a manager that allows you to browse ("Discover" tab), install, and configure your plugins [5]. Installation Plugins are typically installed from these marketplaces, which Claude Code then caches locally for future use [1]. When installing, users can often choose the scope, such as user-wide, per-project, or local-only [8][7]. Anthropic also provides a demo marketplace (claude-code-plugins) for examples of what the plugin system can do [5][9].

Correct the Claude Code plugin instructions.
Use /plugin consistently. A false enabledPlugins entry disables a plugin; it does not prove that the plugin is installed. State that enabled plugins can add always-on listing tokens and that components can also incur on-invoke costs. Use claude plugin details <name> without the marketplace suffix.

Next.js App Router Server and Client Components use client navigation form submission pre-rendered server initial load official docs💡 Result:
In the Next.js App Router, the rendering and navigation architecture relies on the interplay between Server Components, Client Components, and the React Server Component (RSC) Payload [1][2]. Server Components run exclusively on the server, generating the RSC Payload—a serialized representation of the component tree that includes the rendered output of Server Components and placeholders/props for Client Components [1][3][2]. They do not ship JavaScript to the client [4][5]. Client Components, marked by the "use client" directive, run on the server during the initial load to produce HTML and then hydrate in the browser to enable interactivity [1][6][2]. Initial Page Load During an initial load, the server produces full HTML via React's streaming renderer [7]. The RSC Payload is typically inlined into this HTML, allowing the client to hydrate without an additional network request [7]. The resulting HTML provides a fast, non-interactive preview before the JavaScript hydrates Client Components to make the page interactive [1]. Client Navigation For client-side navigation (e.g., via the Link component or programmatic router methods), the client sends a request to the server with a special header indicating it wants the RSC Payload rather than full HTML [7]. The server responds with only the binary RSC Payload, which the client-side router uses to reconcile the UI without a full page refresh [3][7][2]. Prefetching often happens in the background when links enter the viewport, ensuring that this payload is ready for instant navigation [8][9][2]. Form Submission The Next.js Form component (next/form) facilitates client-side navigation and progressive enhancement [10]. When a form is submitted: - If JavaScript is loaded, the default browser form submission is prevented [11][12]. - The form data is processed, and the router performs a client-side navigation (e.g., updating URL search params) by fetching the new RSC Payload from the server [10][11]. - If JavaScript is not yet loaded or is disabled, the form falls back to standard HTML form submission, ensuring the application remains functional [10][12]. - When combined with Server Actions, form submissions can perform data mutations on the server, followed by a re-render and a redirect or refresh to update the UI via the standard RSC workflow [12]. Top Results: [1][10][7][2]

site:nextjs.org/docs Next.js 16 caching fetch cache no-store use cache cacheLife ordinary fetch default💡 Result:
In Next.js 16, the caching model has transitioned to a new approach centered around the "Cache Components" feature, enabled via the
cacheComponents: trueflag innext.config.js[1][2]. Core Caching Concepts in Next.js 16: 1. Fetch Caching: By default,fetchrequests are not cached in the Data Cache and are considered dynamic [3][4]. To cache a specificfetchrequest, you must explicitly opt in by setting thecacheoption to'force-cache'[5][4]. Settingcache: 'no-store'explicitly opts the request out of any potential caching [5]. Note that whilefetchitself is not cached by default, Next.js may still prerender routes containing these fetches into a static HTML shell unless dynamic APIs (likecookies()orheaders()) force the route to be fully dynamic [4][6]. 2. The "use cache" Directive: Theuse cachedirective is the primary tool for caching component or function return values [7][6]. When applied to an async function or component, it caches the function's result [7]. Unlikefetchcaching, which is request-based,use cacheis scoped to the execution of the function or component itself [7][6]. 3. cacheLife:cacheLifeis used alongsideuse cacheto define the lifetime of the cached data [8]. It utilizes profiles defined in yournext.config.js(or preset defaults likedefault,seconds,minutes, etc.) to controlstale(client-side cache time),revalidate(server-side refresh frequency), andexpire(maximum time before forced dynamic) behaviors [2][8]. It is recommended to explicitly set acacheLifeprofile in everyuse cachescope to ensure predictable caching behavior [8]. 4. Migrating from Previous Models: If you are upgrading from earlier versions, note thatcacheComponentsis the unified flag that replaces experimental flags likedynamicIOandunstable_useCache[1]. Many previously experimental APIs, such ascacheLifeandcacheTag, are now stable and should be imported fromnext/cachewithout theunstable_prefix [9]. Summary Table: - Defaultfetchbehavior: Uncached (dynamic) [3][4]. - To cachefetch: Use{ cache: 'force-cache' }[5][4]. - To cache functions/components: Useuse cachedirective [7][6]. - To control cache duration: UsecacheLifewith defined profiles [2][8].Citations:

site:nextjs.org/docs/app Next.js 16 ISR revalidate dynamic rendering fetch cache no-store💡 Result:
In Next.js 16, caching and revalidation have been unified under the Cache Components model, which replaces earlier experimental features like
dynamicIOanduseCache[1][2]. Incremental Static Regeneration (ISR) and data caching are managed through the following mechanisms: 1. ISR and Revalidation: ISR is primarily configured using thecacheLifefunction [3] and theuse cachedirective [4]. To revalidate cached content, you userevalidateTag()orrevalidatePath()[5]. In Next.js 16,revalidateTag()now requires a second argument—acacheLifeprofile—to specify revalidation behavior [1]. For scenarios requiring immediate updates (read-your-writes),updateTag()can be used within Server Actions [1]. 2. Fetch Caching andno-store: When usingfetchin Next.js 16, settingcache: 'no-store'ornext: { revalidate: 0 }opts the request out of the persistent cache [6][7]. This causes the data to be fetched on every request, effectively making the affected component or page dynamic [7]. 3. Dynamic Rendering: Opting out of caching (e.g., viano-storeor using runtime APIs likecookies()orheaders()) forces the page to be rendered dynamically at request time [7][8]. In the Cache Components model, you can mix static and dynamic content within the same route [3][2]. Next.js can prerender a static App Shell while dynamic data streams in [9][2]. If a component or data fetch is uncached, it becomes a dynamic hole that is resolved at request time [3]. 4. Deprecations:unstable_noStoreis considered a legacy API in Next.js 16 [6]. It is recommended to useconnection()to opt out of prerendering [6], or simply use standardcache: 'no-store'configurations onfetchcalls [6][7]. Summary of interactions: - Settingno-storeon a fetch request prevents that specific data from being cached, forcing a fresh fetch on every request [7]. - This does not disable ISR for the entire page; rather, it creates a dynamic boundary [3][2]. - Components that depend on uncached data will render dynamically, while other parts of the page can remain statically cached viause cacheor ISR-configuredgenerateStaticParams[9][3][8].Citations:

The README had no link to a running instance. For a template repo that is the first thing an evaluator wants — the screenshots show light/dark mode, but nothing let you click through to it. It now links to https://nextjs-base-hello.vercel.app, placed directly under the screenshots. The rest of this message is how that URL came to exist, because getting there was not obvious. The URL was not presentable. Vercel had generated nextjs-base-livid.vercel.app: .vercel.app subdomains are globally unique and nextjs-base.vercel.app is owned by another account (it returns 402, not 404), so Vercel appended a random word. Fine as an internal address, poor as the first link in a public README. `vercel project rename` was necessary but not sufficient, in two ways worth remembering. It only affects new deployments. Immediately after the rename every nextjs-base-hello URL still 404'd and the old ones still served; nothing moved until a redeploy was triggered. And it does not move the production alias. After renaming and redeploying, previews read nextjs-base-hello while production still read nextjs-base-livid — the production alias is generated once for the project and does not follow a rename. Vercel's docs cover the new URL format but not this; the CLI said it plainly, printing "To deploy to production (nextjs-base-livid.vercel.app)" after the rename had supposedly taken effect. `vercel alias set` looked like the fix and is not. It pins a hostname to one specific deployment, so the README link would have frozen on whichever build was live when it ran and gone stale at the next merge to main. `vercel alias list` is how the two are told apart: manually-set aliases appear there with their pinned source deployment, auto-managed production domains do not appear at all. The fix was the dashboard — Settings -> Domains -> Edit domain, choosing "Remove old domain" over "Redirect old domain to new" so the project's production domain is replaced rather than duplicated. That domain is the thing Vercel re-points at every production deploy. nextjs-base-livid.vercel.app now 404s, confirming replacement rather than a second alias alongside. Two loose ends, both expected to resolve on the next production deploy: - The `vercel alias set` entry from the discarded approach is still listed against nextjs-base-hello.vercel.app. It targets the same deployment as the new production domain, so it is currently invisible, but it has not been removed. - Aliases minted before the rename still resolve under the old name (nextjs-base-michellepace-team, nextjs-base-git-main-michellepace-team). Orphans, not links. Verified by curl: nextjs-base-hello.vercel.app 200, nextjs-base-livid.vercel.app 404, branch preview nextjs-base-hello-git-chore-update-deps-... 200. Not yet verified through a production deploy — merging this PR is that test. `vercel inspect` still lists the dead -livid alias, so its output lags; curl is the reliable check.
