🧹 Nitpick comments (16)
e2e/react-start/basic-nitro/tests/setup/global.teardown.ts (1)

1-3: Add explicit return type annotation for TypeScript strict mode.

The async function should have an explicit return type annotation for compliance with strict type safety.

🔎 Proposed fix
-export default async function teardown() {
+export default async function teardown(): Promise<void> {
   // No additional teardown needed for Nitro
 }
e2e/react-start/basic-nitro/.gitignore (1)

1-11: Add .nitro pattern for consistency with parallel Nitro e2e projects.

The e2e/solid-start/basic-nitro-spa/.gitignore includes .nitro (line 7), but this file omits it. Since both are Nitro-based e2e setups, ensure consistency by adding the .nitro pattern.

🔎 Proposed fix
 dist
 .output
+.nitro

 /test-results/
e2e/solid-start/basic-nitro/src/components/NotFound.tsx (1)

3-3: Improve type safety for children prop.

The children prop is typed as any, which bypasses TypeScript's type checking. For SolidJS components, use a more specific type like JSX.Element or JSX.Element | undefined.

🔎 Suggested type improvement
-export function NotFound({ children }: { children?: any }) {
+export function NotFound({ children }: { children?: JSX.Element }) {

If you need to support multiple types of children (strings, elements, etc.), you can use a union type:

-export function NotFound({ children }: { children?: any }) {
+export function NotFound({ children }: { children?: JSX.Element | string }) {

As per coding guidelines: Use TypeScript strict mode with extensive type safety for all code.

e2e/react-start/basic-nitro/package.json (1)

20-31: Use workspace:* for internal dependencies per coding guidelines.

The internal TanStack packages should use workspace:* instead of workspace:^ to align with project conventions.

🔎 Proposed fix
   "dependencies": {
-    "@tanstack/react-router": "workspace:^",
-    "@tanstack/react-router-devtools": "workspace:^",
-    "@tanstack/react-start": "workspace:^",
+    "@tanstack/react-router": "workspace:*",
+    "@tanstack/react-router-devtools": "workspace:*",
+    "@tanstack/react-start": "workspace:*",
     "react": "^19.0.0",
     "react-dom": "^19.0.0"
   },
   "devDependencies": {
     "@playwright/test": "^1.50.1",
     "@tailwindcss/postcss": "^4.1.15",
-    "@tanstack/router-e2e-utils": "workspace:^",
-    "@tanstack/nitro-v2-vite-plugin": "workspace:^",
+    "@tanstack/router-e2e-utils": "workspace:*",
+    "@tanstack/nitro-v2-vite-plugin": "workspace:*",

As per coding guidelines, use workspace:* for internal dependencies.

e2e/solid-start/basic-nitro-spa/src/styles/app.css (1)

3-30: Consider consolidating the two @layer base blocks.

Both blocks target @layer base. While functionally correct, consolidating them improves readability. Also note that the border-color rule on lines 4-10 and the @apply border-gray-200 on line 19 both target * - the latter will take precedence.

🔎 Proposed consolidation
 @import 'tailwindcss';

 @layer base {
   *,
   ::after,
   ::before,
   ::backdrop,
   ::file-selector-button {
     border-color: var(--color-gray-200, currentcolor);
   }
-}

-@layer base {
   html {
     color-scheme: light dark;
   }

   * {
     @apply border-gray-200 dark:border-gray-800;
   }

   html,
   body {
     @apply text-gray-900 bg-gray-50 dark:bg-gray-950 dark:text-gray-200;
   }

   .using-mouse * {
     outline: none !important;
   }
 }
e2e/solid-start/basic-nitro/src/styles/app.css (1)

3-30: Consider combining the duplicate @layer base blocks.

The file contains two separate @layer base declarations. For better organization and maintainability, these should be combined into a single block.

🔎 Proposed consolidation
 @import 'tailwindcss';
 
 @layer base {
   *,
   ::after,
   ::before,
   ::backdrop,
   ::file-selector-button {
     border-color: var(--color-gray-200, currentcolor);
   }
-}
-
-@layer base {
+
   html {
     color-scheme: light dark;
   }
 
   * {
     @apply border-gray-200 dark:border-gray-800;
   }
 
   html,
   body {
     @apply text-gray-900 bg-gray-50 dark:bg-gray-950 dark:text-gray-200;
   }
 
   .using-mouse * {
     outline: none !important;
   }
 }
e2e/react-start/basic-nitro/src/router.tsx (1)

10-11: Inconsistent component passing pattern.

defaultErrorComponent passes the component reference directly, while defaultNotFoundComponent wraps it in an arrow function. For consistency and clarity, both should use the same pattern.

🔎 Suggested consistency fix

Option 1: Use direct references for both

     defaultErrorComponent: DefaultCatchBoundary,
-    defaultNotFoundComponent: () => <NotFound />,
+    defaultNotFoundComponent: NotFound,

Option 2: Wrap both in arrow functions

-    defaultErrorComponent: DefaultCatchBoundary,
+    defaultErrorComponent: () => <DefaultCatchBoundary />,
     defaultNotFoundComponent: () => <NotFound />,

Option 1 is preferred for simplicity unless there's a specific reason to use a wrapper function.

e2e/react-start/basic-nitro/tsconfig.json (1)

1-22: LGTM! Consider adding Vite types for consistency.

The TypeScript configuration is properly set up with strict mode and appropriate React settings. All required compiler options are present.

For consistency with the Solid variant (e2e/solid-start/basic-nitro/tsconfig.json), consider adding the types field to explicitly include Vite client types.

🔎 Optional enhancement for consistency
     "paths": {
       "~/*": ["./src/*"]
     },
-    "noEmit": true
+    "noEmit": true,
+    "types": ["vite/client"]
   }
 }
e2e/react-start/basic-nitro/src/components/DefaultCatchBoundary.tsx (1)

39-48: Use a button element instead of Link for the "Go Back" action.

The current implementation uses a Link component with to="/" but prevents default navigation and calls window.history.back() instead. This creates semantic confusion and accessibility issues:

  • Screen readers announce "link to home" but the action goes back in history
  • The to="/" attribute is never used
  • Violates semantic HTML best practices

A <button> element is more appropriate for JavaScript-triggered actions that don't perform standard navigation.

🔎 Proposed refactor
        ) : (
-         <Link
-           to="/"
+         <button
+           onClick={() => {
+             window.history.back()
+           }}
            className={`px-2 py-1 bg-gray-600 dark:bg-gray-700 rounded-sm text-white uppercase font-extrabold`}
-           onClick={(e) => {
-             e.preventDefault()
-             window.history.back()
-           }}
          >
            Go Back
-         </Link>
+         </button>
        )}
e2e/solid-start/basic-nitro-spa/src/components/DefaultCatchBoundary.tsx (1)

39-48: Clarify "Go Back" navigation semantics.

The "Go Back" link has to="/" but prevents default and calls window.history.back(). This creates a mismatch between the href (which points to home) and the actual behavior (which navigates back in history). Consider using a <button> element instead for better semantic clarity.

🔎 Suggested refactor
-        <Link
-          to="/"
-          class={`px-2 py-1 bg-gray-600 dark:bg-gray-700 rounded-sm text-white uppercase font-extrabold`}
-          onClick={(e) => {
-            e.preventDefault()
-            window.history.back()
-          }}
-        >
-          Go Back
-        </Link>
+        <button
+          onClick={() => {
+            window.history.back()
+          }}
+          class={`px-2 py-1 bg-gray-600 dark:bg-gray-700 rounded-sm text-white uppercase font-extrabold`}
+        >
+          Go Back
+        </button>
e2e/react-start/basic-nitro/src/routes/__root.tsx (1)

61-64: Consider adding lang attribute to HTML element.

While this is an e2e test fixture, adding lang="en" to the <html> element is a best practice for accessibility and proper document semantics.

🔎 Proposed enhancement
-    <html>
+    <html lang="en">
       <head>
         <HeadContent />
       </head>
e2e/solid-start/basic-nitro/tests/app.spec.ts (1)

12-25: Consider adding missing assertion for consistency.

The React variant of this test (at e2e/react-start/basic-nitro/tests/app.spec.ts:26) includes an additional assertion to verify the "Generated at:" timestamp is displayed on the page. Consider adding this for consistency:

await expect(page.getByTestId('generated-at')).toContainText('Generated at:')
e2e/solid-start/basic-nitro/src/utils/seo.ts (1)

1-33: LGTM! Consider filtering undefined values.

The SEO utility function correctly generates meta tags and matches the established pattern in the codebase (see examples/solid/start-basic-netlify/src/utils/seo.ts and examples/solid/start-basic-nitro/src/utils/seo.ts).

For a minor improvement, you could filter out tags with undefined content values to avoid rendering content="undefined" in the HTML, though this is not critical for e2e test fixtures.

🔎 Optional enhancement to filter undefined values
   const tags = [
     { title },
     { name: 'description', content: description },
     { name: 'keywords', content: keywords },
     { name: 'twitter:title', content: title },
     { name: 'twitter:description', content: description },
     { name: 'twitter:creator', content: '@tannerlinsley' },
     { name: 'twitter:site', content: '@tannerlinsley' },
     { name: 'og:type', content: 'website' },
     { name: 'og:title', content: title },
     { name: 'og:description', content: description },
     ...(image
       ? [
           { name: 'twitter:image', content: image },
           { name: 'twitter:card', content: 'summary_large_image' },
           { name: 'og:image', content: image },
         ]
       : []),
-  ]
+  ].filter(tag => 'content' in tag ? tag.content !== undefined : true)

   return tags
 }
e2e/solid-start/basic-nitro-spa/tests/app.spec.ts (1)

21-30: Consider using modern Playwright locator API.

Lines 25 and 28 use page.click(), which is deprecated in favor of the locator API. Consider updating to page.locator() or page.getByRole() for better maintainability.

🔎 Suggested modernization
-  await page.click('a[href="/static"]')
+  await page.locator('a[href="/static"]').click()
   await expect(page.getByTestId('static-heading')).toBeVisible()

-  await page.click('a[href="/"]')
+  await page.locator('a[href="/"]').click()
   await expect(page.getByTestId('home-heading')).toBeVisible()
e2e/solid-start/basic-nitro-spa/package.json (2)

20-24: Internal dependencies use workspace:^ instead of workspace:*.

The coding guidelines specify using workspace:* for internal dependencies. Currently, these use workspace:^. While both are valid workspace protocols, you may want to align with the repository's convention.

Suggested change
   "dependencies": {
-    "@tanstack/solid-router": "workspace:^",
-    "@tanstack/solid-router-devtools": "workspace:^",
-    "@tanstack/solid-start": "workspace:^",
+    "@tanstack/solid-router": "workspace:*",
+    "@tanstack/solid-router-devtools": "workspace:*",
+    "@tanstack/solid-start": "workspace:*",
     "solid-js": "^1.9.10"
   },

26-39: DevDependencies: Internal packages use workspace:^ and nitro uses unpinned nightly.

Two observations:

  1. Internal dev dependencies (@tanstack/router-e2e-utils, @tanstack/nitro-v2-vite-plugin) use workspace:^ rather than workspace:* per coding guidelines.

  2. The nitro dependency uses npm:nitro-nightly@latest, which could cause non-reproducible builds if nightly versions introduce breaking changes.

Suggested change for workspace protocol
   "devDependencies": {
     "@playwright/test": "^1.50.1",
     "@tailwindcss/postcss": "^4.1.15",
-    "@tanstack/router-e2e-utils": "workspace:^",
-    "@tanstack/nitro-v2-vite-plugin": "workspace:^",
+    "@tanstack/router-e2e-utils": "workspace:*",
+    "@tanstack/nitro-v2-vite-plugin": "workspace:*",

File: e2e/react-start/custom-basepath/package.json:13-17
Timestamp: 2025-12-25T13:04:55.492Z
Learning: In the TanStack Router repository, e2e test scripts are specifically designed to run in CI (which uses a Unix environment), so Unix-specific commands (like `rm -rf`, `&` for backgrounding, and direct environment variable assignments without `cross-env`) are acceptable in e2e test npm scripts.

Timestamp: 2025-10-14T18:59:33.990Z
Learning: In TanStack Router e2e test files, when a route parameter is validated at the route level (e.g., using zod in validateSearch or param validation), switch statements on that parameter do not require a default case, as the validation ensures only expected values will reach the switch.

Timestamp: 2025-10-01T18:31:35.420Z
Learning: Do not review files named `routeTree.gen.ts` in TanStack Router repositories, as these are autogenerated files that should not be manually modified.

Timestamp: 2025-10-08T08:11:47.088Z
Learning: Test snapshot files in the router-generator tests directory (e.g., files matching the pattern `packages/router-generator/tests/generator/**/routeTree*.snapshot.ts` or `routeTree*.snapshot.js`) should not be modified or have issues flagged, as they are fixtures used to verify the generator's output and are intentionally preserved as-is.

File: packages/router-generator/src/generator.ts:654-657
Timestamp: 2025-12-17T02:17:55.086Z
Learning: In `packages/router-generator/src/generator.ts`, pathless_layout routes must receive a `path` property when they have a `cleanedPath`, even though they are non-path routes. This is necessary because child routes inherit the path from their parent, and without this property, child routes would not have the correct full path at runtime.

File: packages/start-client-core/src/client/hydrateStart.ts:6-9
Timestamp: 2025-11-02T16:16:24.898Z
Learning: In packages/start-client-core/src/client/hydrateStart.ts, the `import/no-duplicates` ESLint disable is necessary for imports from `#tanstack-router-entry` and `#tanstack-start-entry` because both aliases resolve to the same placeholder file (`fake-start-entry.js`) in package.json during static analysis, even though they resolve to different files at runtime.

Learning: In `packages/router-core/src/new-process-route-tree.ts`, the matching logic intentionally allows paths without trailing slashes to match index routes with trailing slashes (e.g., `/a` can match `/a/` route), but not vice-versa (e.g., `/a/` cannot match `/a` layout route). This is implemented via the condition `!pathIsIndex || node.kind === SEGMENT_TYPE_INDEX` and is a deliberate design decision to provide better UX by being permissive with missing trailing slashes.

⚠️ Potential issue | 🟡 Minor

Conditionally include meta tags when values are undefined.

The function unconditionally includes description and keywords in the meta tags array, even when they're undefined. This results in invalid HTML meta tags with content: undefined.

For example, calling seo({ title: 'Test' }) generates:

<meta name="description" content="undefined">
<meta name="keywords" content="undefined">

Filter out tags with undefined content values or conditionally spread them similar to the image handling.

⚠️ Potential issue | 🟡 Minor

Misleading to prop on history navigation link.

The "Go Back" link has to="/" but the onClick handler prevents default navigation and uses window.history.back() instead. The to prop is never used and creates confusion about the link's actual behavior.

🔎 Suggested fix

Either remove the to prop entirely and use a button, or use a semantic placeholder:

-        <Link
-          to="/"
-          class={`px-2 py-1 bg-gray-600 dark:bg-gray-700 rounded-sm text-white uppercase font-extrabold`}
+        <button
           onClick={(e) => {
             e.preventDefault()
             window.history.back()
           }}
+          class={`px-2 py-1 bg-gray-600 dark:bg-gray-700 rounded-sm text-white uppercase font-extrabold`}
-        >
+        >
           Go Back
-        </Link>
+        </button>

Alternatively, if you want to keep the Link component for styling consistency, use a more semantic approach:

         <Link
-          to="/"
+          to={window.location.pathname}

lines 39 to 48, the Link has a misleading to="/" prop while the onClick prevents
default navigation and calls window.history.back(); replace the Link with a
semantic <button> (keep the same class string and the onClick that calls
window.history.back(), remove e.preventDefault()) so the element's semantics
match its behavior and the unused to prop is removed.

⚠️ Potential issue | 🟡 Minor

Fix hex color typo.

The hex color value has 5 digits instead of 6. Valid hex colors should be either 3 or 6 hex digits.

🔎 Proposed fix
-      { rel: 'manifest', href: '/site.webmanifest', color: '#fffff' },
+      { rel: 'manifest', href: '/site.webmanifest', color: '#ffffff' },

In e2e/solid-start/basic-nitro/src/routes/__root.tsx around line 51, the
manifest link object uses an invalid 5-digit hex color '#fffff'; replace it with
a valid 6-digit or 3-digit hex (for example '#ffffff' or '#fff') so the color
value is valid CSS hex notation.

⚠️ Potential issue | 🔴 Critical

Fix server function to return correct runtime message.

The getData server function returns "Running in Unknown" when executed server-side (where navigator is undefined), but the test at e2e/solid-start/basic-nitro/tests/app.spec.ts:8 expects "Running in Node.js". This mismatch will cause the test to fail.

🔎 Proposed fix to detect Node.js runtime
 const getData = createServerFn().handler(() => {
   return {
-    message: `Running in ${typeof navigator !== 'undefined' ? navigator.userAgent : 'Unknown'}`,
+    message: `Running in ${typeof process !== 'undefined' && process.versions?.node ? 'Node.js' : 'Unknown'}`,
     runtime: 'Nitro',
   }
 })

In e2e/solid-start/basic-nitro/src/routes/index.tsx around lines 9 to 14, the
server function currently uses navigator presence to build the runtime message
and thus returns "Unknown" server-side; update the runtime detection to check
for Node.js (e.g. typeof process !== 'undefined' && process.versions &&
process.versions.node) and return "Node.js" when that check succeeds, otherwise
fall back to using navigator.userAgent for browsers or a default; adjust the
returned message to use "Node.js" on server so the test expecting "Running in
Node.js" passes.
