  "body": "---\nname: sfnext-routing\ndescription: >-\n  Add and change pages in a Storefront Next project: flat-file routes in src/routes, layout routes (_app, _checkout, _empty), splat routes for product and category pages, action.* and resource.* routes, src/route-paths.ts (routes, resourceRoutes, routeHref), site-aware Link and useNavigate wrappers, SeoMeta and JsonLd head tags, multi-site /:siteId/:localeId URL prefixes, url.seoRoutes and excludeRoutes, extension routes, and the SLAS callback routes. Use for \"add a page\", \"new route\", \"why is my link missing the site prefix\", \"route file naming\", \"redirect to login\", or a 404 on a new URL. Do not use for loader/action/fetcher data code (use `storefront-next:sfnext-data-fetching`), shouldRevalidate (use `storefront-next:sfnext-revalidation`), SEO strategy such as sitemaps and canonical rules (use `storefront-next:sfnext-seo`), or Page Designer regions (use `storefront-next:sfnext-page-designer`).\n---\n\n# Storefront Next Routing\n\nStorefront Next uses React Router 7 framework mode with file-based routes. Every route module lives in `src/routes/`; the file name is the URL. Your project also ships `docs/README-MULTI-SITE.md` (URL prefix, locale and site detection) and `docs/README-SEO.md` (titles, meta tags, canonical URLs); read those for depth.\n\n## How routes are discovered\n\n`src/routes.ts` imports `flatRoutes` from `@salesforce/storefront-next-runtime/routing` (not `@react-router/fs-routes`). It is a drop-in wrapper that:\n\n1. scans `src/routes/` (test files are ignored),\n2. merges routes from `src/extensions/\u003cname>/routes/` (see `storefront-next:sfnext-extensions`),\n3. wraps every route in the `app.url.prefix` pattern (default `/:siteId/:localeId`) through `src/app-wrapper.tsx`, and applies `app.url.seoRoutes` aliases to the product and category splats.\n\nThe two SLAS callback routes (`resource.slas-reset-password-callback.ts`, `resource.slas-passwordless-login-callback.ts`) are deliberately excluded from discovery in `src/routes.ts` and registered by hand at the bare paths `/reset-password-callback` and `/passwordless-login-callback`, outside the prefix, so a single callback URL works for all sites. If you add another server-to-server callback that cannot carry a site prefix, follow the same pattern in `src/routes.ts`.\n\n## Route tree (what exists)\n\n| Pattern | Files | Notes |\n|---|---|---|\n| `_app` layout | `_app.tsx` | header/footer shell; loads navigation; `shouldRevalidate` returns `false` |\n| Home, search, cart, wishlist | `_app._index.tsx`, `_app.search.tsx`, `_app.cart.tsx`, `_app.wishlist.tsx`, `_app.about-us.tsx` | |\n| Product detail | `_app.p.$.tsx` | splat; URL shape is build-time configurable (`url.seoRoutes`) |\n| Category / listing | `_app.c.$.tsx` | splat; URL shape is build-time configurable (`url.seoRoutes`) |\n| Account | `_app.account.tsx` (layout + auth guard), `_app.account.overview`, `.orders`, `.orders.$orderNo`, `.addresses`, `.payment-methods`, `.wishlist`, `.passkeys`, `.store-preferences` | |\n| Orders | `_app.order-confirmation.$orderNo.tsx`, `_app.order-lookup.*` (`results.$orderNo`, `verify.$orderNo`) | param is `$orderNo` |\n| `_checkout` layout | `_checkout.tsx`, `_checkout.checkout.tsx` | checkout chrome |\n| `_empty` layout | `_empty.tsx`, `_empty.login`, `.signup`, `.forgot-password`, `.reset-password`, `.logout`, `.maintenance`, `.oauth2.jwks`, `.preview.component`, `_empty.$.tsx` (catch-all) | no header/footer; there is no `_auth` layout |\n| Mutations | `action.*.ts(x)` (cart, wishlist, checkout, OTP, passkey, consent, site context...) | no UI; see `storefront-next:sfnext-data-fetching` |\n| Data endpoints | `resource.*.ts(x)` (recommendations, basket-products, category-products, analytics-proxy, `resource.api.client.$resource.ts`...) | no UI |\n\nNaming rules (flat routes): `.` becomes `/`, `$name` is a param, `$` alone is a splat, a leading `_` segment is a pathless layout, `_index` is the index route. Pick the layout by prefix: `_app.` for standard pages, `_checkout.` for checkout, `_empty.` for header-less pages.\n\n## Add a page\n\n```tsx\n// src/routes/_app.shipping-policy.tsx  ->  /shipping-policy\nimport type { Route } from './+types/_app.shipping-policy';\nimport { SeoMeta } from '@/components/seo-meta';\nimport { Link } from '@/components/link';\nimport { routes } from '@/route-paths';\n\nexport async function loader({ request }: Route.LoaderArgs) {\n    return { pageUrl: new URL(request.url).href };\n}\n\nexport default function ShippingPolicy({ loaderData }: Route.ComponentProps) {\n    return (\n        \u003c>\n            \u003cSeoMeta title=\"Shipping policy\" description=\"How we ship.\" openGraph={{ url: loaderData.pageUrl }} />\n            \u003ch1>Shipping policy\u003c/h1>\n            \u003cLink to={routes.cart}>Back to cart\u003c/Link>\n        \u003c/>\n    );\n}\n```\n\nChecklist for a new page:\n\n1. Create the file under `src/routes/` with the right layout prefix.\n2. Import types from `./+types/\u003cfile-name>` (`Route.LoaderArgs`, `Route.ComponentProps`, `Route.ActionArgs`). These are generated by `pnpm typecheck` (runs `react-router typegen`) and `pnpm dev`; run one if the import is unresolved.\n3. Add an entry to `routes` (page) or `resourceRoutes` (action/resource) in `src/route-paths.ts`. That file is the single source of truth for navigable paths. Keep it in sync when you rename or delete route files.\n4. Render `\u003cSeoMeta>` (and `\u003cJsonLd>` from `@/components/json-ld` for structured data) inside the component. React 19 hoists these tags to `\u003chead>` and they work with streaming. Use `meta` exports only when a route already does.\n5. Add locale strings for user-facing text (`storefront-next:sfnext-i18n`) and a test next to the route (`storefront-next:sfnext-testing`).\n\n## Links and navigation: always use the project wrappers\n\n```tsx\nimport { Link, NavLink } from '@/components/link';\nimport { useNavigate } from '@/hooks/use-navigate';\nimport { href } from 'react-router';\nimport { routes, routeHref, resourceRoutes } from '@/route-paths';\n\n\u003cLink to={routes.cart}>Cart\u003c/Link>\n\u003cLink to={routeHref(routes.accountOrderDetail, { orderNo })}>Order\u003c/Link>\n```\n\n`Link`, `NavLink` and `useNavigate` from `@/components/link` and `@/hooks/use-navigate` apply the site/locale prefix (`buildUrl`). The React Router originals compile but silently produce unprefixed URLs that break multi-site routing. `AGENTS.md` makes this a hard rule.\n\nFor product and category URLs use the helpers in `@/route-paths` (`createProductUrl`, `createCategoryUrl`, `createCategoryNavigationUrl`) with the SEO URL context so links follow `url.seoRoutes`. In server code (redirects), use `buildUrlFromContext(routes.login, context)` from `@/lib/url.server`:\n\n```ts\nimport { redirect } from 'react-router';\nimport { routes } from '@/route-paths';\nimport { buildUrlFromContext } from '@/lib/url.server';\n\nthrow redirect(buildUrlFromContext(routes.login, context));\n```\n\nForm and fetcher `action` targets come from `resourceRoutes` (for example `resourceRoutes.cartItemAdd`), which are excluded from the site prefix via `app.url.excludeRoutes` in `config.server.ts` (`['/resource/**', '/action/**']` by default). A new `action.*` or `resource.*` route needs no prefix handling; a new page route gets it automatically.\n\n## URL configuration\n\n`app.url` in `config.server.ts` (`prefix`, `excludeRoutes` and `seoRoutes` are protected config paths: set them in the file and rebuild, they cannot be overridden with `PUBLIC__` env vars; see `storefront-next:sfnext-configuration`) controls `prefix`, `excludeRoutes`, search-param mode, detection and `seoRoutes` (configurable product and category URL grammars). Changing the prefix or `seoRoutes` affects every link; follow `docs/README-MULTI-SITE.md` in your project rather than editing ad hoc.\n\n## Protecting routes\n\nThere is no `_auth` layout. Guard in the loader: read the session with `getAuth(context)` from `@/middlewares/auth.server` and `throw redirect(...)` to `routes.login` (see `_app.account.tsx` and `_app.wishlist.tsx`). Auth details: `storefront-next:sfnext-authentication`.\n\n## Rules to keep in mind\n\n- Only server `loader` and `action` exports are allowed; no `clientLoader`/`clientAction`.\n- Throw `new Response('...', { status: 404 })` for missing content so the right HTTP status reaches crawlers.\n- Resource routes called from the browser should reject cross-origin requests (see `resource.recommendations.ts` for the pattern).\n- Deeper references: [ROUTE-CONVENTIONS.md](references/ROUTE-CONVENTIONS.md) for exports and naming, [URLS-AND-SEO-ROUTES.md](references/URLS-AND-SEO-ROUTES.md) for prefixes and SEO aliases.\n\n## Finding more\n\nRead `AGENTS.md` in your project for the doc index. For other framework questions use `b2c docs search \"storefront next routing\"` (or the `docs_search` MCP tool).\n\n## Related Skills\n\n- `storefront-next:sfnext-data-fetching` - loaders, actions, fetchers\n- `storefront-next:sfnext-revalidation` - `shouldRevalidate` policy per route\n- `storefront-next:sfnext-seo` - canonical URLs, structured data, sitemaps\n- `storefront-next:sfnext-page-designer` - `@PageType` and regions on routes\n- `storefront-next:sfnext-extensions` - routes contributed by extensions\n- `storefront-next:sfnext-authentication` - sessions and login flows\n- `storefront-next:sfnext-overview` - architecture map\n\n---\nSource: https://github.com/SalesforceCommerceCloud/b2c-developer-tooling/blob/main/skills/storefront-next/skills/sfnext-routing/SKILL.md\nAuthor: Salesforce Commerce Cloud (SalesforceCommerceCloud/b2c-developer-tooling), licensed Apache-2.0.
